Are Index Funds Eating the World? (wsj.com)

As always when articles like this come up, I want to issue the usual reminder to HN to beware of what pg called "submarine stories" (http://paulgraham.com/submarine.html). There are a lot of people who stand to lose a lot of money in fees if "just park it in index funds" becomes more popular advice than it is already. Not to say the analysis above is wrong, but just keep in mind (especially at the WSJ) that it may not be coming from sources with your best interest in mind.


"A report this past week from investment firm Sanford C. Bernstein, titled “The Silent Road to Serfdom: Why Passive Investing Is Worse than Marxism,” warned that..."

It would be funny if it wasn't so incredibly blatant.


A friend worked there as an investment advisor and wound up quitting because so many of their funds were losing to the market.


Funny enough, index funds outperform hedge funds, etc, however you can outperform the indices by buying stock at 3:00-3:30pm and selling at 4:00pm every day, because that's when many funds vest, and when most of the daily volume occurs. It's a horrible irony. The "3:30 Ramp" is so well known that there's a Twitter parody account followed by huge swaths of "Finance Twitter."


https://twitter.com/RampCapitalLLC http://www.zerohedge.com/news/2013-04-08/invest-330-pm-ramp-...

I barely know anything about trading, and nonetheless this is absolutely glorious. It's grown into a subculture that rivals any subreddit, with its own set of memes, photoshops, even animations. And to listen to the ever-bullish narrator, there's no end in sight to the ramp...


I don't see how this can be a viable strategy, if the effect is so well known. These things only work as long as few people are aware of the pattern.


>> Funny enough, index funds outperform hedge funds, etc

I'm weary of reading this on Hacker News. Index funds do not beat hedge funds. That statement is devoid of nuance and accuracy, and contributes to a narrative that active managers do not have a skillset or function.

Most hedge funds do not maintain performance that beats the market, but many do. This is easily verifiable.


>Most hedge funds do not maintain performance that beats the market, but many do. This is easily verifiable.

Yes, it's easily verifiable. It's also completely meaningless without a rational way to predict which ones will be outperforming in the future.


Exactly!

On a related note, Buffet vs. Protege Partners: http://longbets.org/362/


It's not at all meaningless, because it is rational to use past performance as a predictor of future performance.

Past performance does not necessarily indicate future performance, and it should not be the only predictor, but to dismiss a fund's history as inconsequential to its future is silly.

A fund's prior performance is a useful signal that can be rationally incorporated into a risk versus reward decision process.


>> it is rational to use past performance as a predictor of future performance

No, it isn't and all the funds explicitly warn you that you shouldn't do it.

The point is, funds perfomance is just a bad case of "survivor bias". Many funds are created, most of them tank and you never hear about them again, but few get lucky, make some remarkable return and get their 5 minutes of fame.

There is also one more problem with the "successfull" funds:

let's say that some fund manager actually has a secret strategy that works. At the begining, he or she just takes some initial money from investors and invest it in whatever the secret strategy suggests.

Unfortunately as soon as fund becomes popular, and people start putting more and more money in it the strategy gets thrown through the window. Why? because if you put your money in a fund that fund MUST use your money to buy stocks. Even if manager thinks that this is a bad time for buying.

Therefore, as soon as fund becomes popular it stops being strategy-based and becomes "bubble based" :)


The problem with managed funds is that the whole fund market is completely skewed by survivorship bias. Despite all the warnings not to do it, people do value funds based on past performance, and because they do that, fund managers eliminate funds with bad past performance, so the only funds you'll ever see in the market are ones with good past performance, but there's still absolutely zero evidence that any of those funds will perform well in the future, because the actual performance is indistinguishable from random chance.


>Past performance does not necessarily indicate future performance, and it should not be the only predictor, but to dismiss a fund's history as inconsequential to its future is silly.

I'm not dismissing it unconditionally, but I'm not going to believe it unless I see the data. What's the probability of a fund outperforming given it has outperformed the year before?


If it has been doing it for three of the last four years, good. If it has been doing it for five of the last seven years, dodgy. IANACFA


The median index fund easily beats the median hedge fund after accounting for fees on both.

Are you more comfortable with that statement?

Also, here's another one to ponder: It may be just as hard to pick a fund manager who will outperform his/her peers as it is to pick a stock that will outperform its peers. For this reason alone, I index almost all my money.


Is it enough to cover the typical discount broker commission?


That would depend on your trading volume.


Why not choose the 3 or 4 that happened to perform well and buy a full-page ad featuring them in Wall Street Journal, Money and Kiplinger's, the way every other fund company had done?


Wooooow.

It's always funny/concerning when people who make money by taking advantage of others by leveraging their lack of education then start acting as though fixes to that imbalance are afronts to their earned/deserved position.

Although, when any industry changes, those that stand to lose always put up a fight. Everyone thinks everything they have is deserved or owed to them.


Wow I thought you were joking about that book title


Poe's Law.


I disagree, it's funny because it's so incredibly blatant.


> Why Passive Investing is Worse than Hitler


"The tone of the report was a little operatic, but the question it raised is deadly serious."


But there is a story here:

>Because corporations know that, says Prof. Heemskerk, coziness and complacency may arise. “If you have only long-term investors, how do you keep management on their toes?” he asks. “Where are the checks and balances when you have such large block holdings?”

The whole system depends on the fact that investors have an interest in voting for a competent board and are willing to sell their shares if the company doesn't seem to be managed well. If the actual owners of the company aren't paying attention the opportunities for self-dealing and just plain incompetence on the part of company officers multiply.


Not really. If Index funds become more popular than regular trading becomes more profitable. The opposite of what you say is actually true.


It may make regular trading more profitable, but most asset managers are paid for getting more assets under management, not their fund's profits.

So siphoning money away to index funds does put a direct crimp on active managed fund managers' compensation.


> asset managers are paid for getting more assets under management, not their fund's profits.

I've always wondered why they aren't paid a percentage of profits? That would align their interests with the customers'.


They're generally paid both. They often charge "two and twenty" meaning 2% yearly of the assets under management and 20% of the profit. (Of course they don't absorb 20% of the losses in a bad year)


That's only hedge funds, which are a small fraction of total fund capitalization.


What are the percentages of the market occupied by different fund types? Where would I go to look that up?


http://www.hedgefundfacts.org/hedge/wp-content/uploads/2009/...

Page 4

"Hedge funds as a percent of total: 1.1%"


Or even a percentage that increases by the percentage of profit.


If you trade with your own (possibly leveraged) funds, sure. If you're trading with other people's money and rely more on asset management fees than profit-sharing, then your personal expected profits fall when index funds become more popular.


However, running a consumer-facing actively managed fund and taking a percentage fee becomes less profitable if demand shifts from that product to index funds, because there is less money to take a percentage fee out of.


Not really. The "who stands to lose" is money managers/financial advisers, assuming they don't want to become a trader or fund manager.


Yes, but then what's that law of headlines ending with a question mark? The implied answer is typically "no".


The implied answer is typically "yes". It's the _correct_ answer that's typically "no".


According to the wiki article on the subject and as outlined by Marr, the answer to most headlines questions are in the negative. Most people will interpret them in the negative. It may be that the set-up is for people to _consider_ the positive, while answering in the negative.

Great point, I never had a word for it (thanks for the link) but I've felt this whenever reading the high-level economic stories about things like interest rates and the market slowing, etc. The cynic in me just assumes that whatever the author is saying will fail or whatever they're likely shorting.


When people wonder what would happen if index funds become too popular, I usually refer them to Warren Buffet's 2005 essay, 'How to minimize investment returns':

http://www.mymoneyblog.com/how-to-minimize-investment-return...

It is essentially a thought experiment about what would happen if everyone switched to one big index fund.

But, it glosses over the issue of individual security pricing and corporate management, which would become issues in a 100% pure index environment.

Of course, we won't ever get a 100% pure index environment, because the closer you approach it, the more incentive there is for active managers to exist.

I think what is really happening is that as more people use indexing, the less talented active managers are driven out of business. A small number of very talented active managers may eventually find themselves in a highly competitive market to exploit pricing inefficiencies, and they will end up incidentally providing management oversight and marginal pricing services to the indexers. These active managers will probably look more and more like private equity firms (taking an active hand in management), and less and less like traditional arms-length traders.

As long as this small number of talented firms isn't allowed to collude with each other, or self-deal unethically by controlling management, everything should be fine. In fact, having met some less talented active traders in person, I suspect that the quality of marginal pricing and managerial oversight may go _up_ as the number of active managers decreases, and the less informed and talented among them are eliminated.


> As long as this small number of talented firms isn't allowed to collude with each other, or self-deal unethically by controlling management

... and I've got a bridge to sell you.

More seriously though, the smaller the number of players, the more likely (and easy) collusion becomes. Successful cartels always have relatively few players.


This is very true. So many active managers are AUM businesses rather than alpha businesses. Long only funds which use bulge bracket banks as sales channel partners are particularly egregious.


One thing I like to point out whenever this kind of discussion comes up, is that there is no single index. Articles like this always seem to assume that everyone will buy the same index, namely the S&P 500 or total US market.

But that's not what a lot of index investors do. Indexers enjoy adding tilts to their portfolios. So some people will buy value funds, others will buy small cap funds, and yet others will buy small value funds. There are people who overweight certain sectors, like REITs or utilities. There are those who invest in international index funds (with all their variations) and those who don't. So there's a huge number of combinations you can think of when it comes to indexing.

Now, with people indexing like that, there would still be market liquidity. Maybe not as much as when there are single stocks being actively traded, but on any given day there will be people buying into different indexes, selling shares, or rebalancing.

Valuation would become troublesome though, but at least people would still get some return from dividends.


> S&P 500

Plus everyone knows the S&P is a terrible benchmark because it excludes mid- and small-cap cos.

After watching mine from a far for ~7 years, I've come to accept that one really needs to invest in multiple index funds to get global diversification as well.


> Plus everyone knows the S&P is a terrible benchmark because it excludes mid- and small-cap cos.

Such a terrible fund that it is what almost everyone bases their performance off of.


It's really not that bad. If you want, the Wilshire 5k is probably about as broad as you can go. And with market cap weighting, the additional diversification wouldn't likely help much.


Performance is irrespective of representing the market broadly.


Possibly because it's relatively easy to beat.


You can be immensely wealthy if you beat it consistently. Almost no professionals can. Warren Buffet is winning his $1m charity bet that the S&P beats pro hedge funds over a decade:

http://www.cnbc.com/2016/02/16/warren-buffett-slips-but-stil...

> His horse in the race, the Vanguard 500 Index Fund Admiral Shares, which tracks the benchmark S&P 500 index, is up 65.7 percent. That's well ahead of the 21.9 percent average gain for the unnamed five funds of hedge funds chosen by Protege Partners, a New York City money management firm.

So not just an average of hedge funds, but ones specifically selected to out perform by a multi-billion dollar management firm.


Warren Buffet is a spectacular value investor, but those funds are not representative of the best performers in the industry. A brief Google search demonstrates that a variety of hedge funds have consistently beaten the S&P 500 for well over a decade; in some cases, for 25-30 years.

I do agree with you that almost no professional can beat the S&P 500, but I think that is due to a variety of factors, including but not limited to the outright difficulty. For example, if you beat the market consistently you still might not become rich. With $100k in starting capital, "merely" beating the S&P 500 by a few percentage points each year (let's say 10% average annual return instead of 7%) will not make you rich in the conventional sense of the word. This prevents many people with the aptitude from investing in the skill development because they could earn a greater living doing other things.

A trader whose insight is primarily responsible for driving that same return on $2B in assets is already very rich or will very quickly become so. Beating the market with that kind of capital requires an entire infrastructure devoted to trading and execution just to make the trades with minimal market movement and signalling, let alone maintaining alpha on it. Not all people capable of beating the market can do so in a manner that is actually worth their own time, because the scale can be astronomically different.


The key point of the wager is that the bettor must select the funds at a point in time and bet only on the future returns.

Gazing back into the history of thousands of funds to find a few funds who have beaten the S&P 500 over 25 years is interesting, but is far a guarantee that those funds will beat going forward.


Yet most investors can't beat it.


I guess this is a good place to ask: For someone who knows nothing about the market, what would be a good way to invest their money? From the responses here, I'm guessing "park them in an index fund", but is there a trustworthy company I can talk to that will do that?


I would recommend Invest Like a Pro (10 day investing course) [1]. It's written by the founder of YNAB, and gives a really good introduction to different types of funds and investment vehicles.

[1]: https://www.amazon.com/Invest-Like-Pro-10-Day-Investing-eboo...


Find a reputable low cost online broker in your country, look into Vanguard funds.


Hello StavrosK - I recommend you find an RIA (Fee Based Fiduciary Registered Investment Advisor) who offers DIMENSIONAL FUNDS = DFA. www.dfaus.com they are NOT really 'passive' and they are NOT really an 'indexer' - yet - over an extended period of time their funds have demonstrated outperformance when compared to their relevant benchmarks


Quick answer:

You could do a lot worse than parking it in an index fund, so yeah, that's a good approach :) If you have a 401(k) or other retirement account, it is quite common for those to offer an S&P 500 index fund where you could invest your money. If you want to do it in a taxable brokerage account, you should open an account with Vanguard and buy their Total Stock Market index fund (VTSMX, or VTSAX if you have more than $10,000 to invest).

Then stay the course - if the market tanks 50% the day after you put your money in, don't panic. Wait it out. Your investment horizon here is at the very least 10 years.

But that's the quick, the-best-time-to-invest-is-tomorrow-so-just-do-it answer.

There are a number of things you should do if you want to learn more about how to invest your money in stocks (and maybe bonds):

0) A good resource to get started quickly is If You Can, by William Bernstein:

https://smile.amazon.com/If-You-Can-Millennials-Slowly-ebook...

But you can skip it if you want to dive deeper with the stuff that follows.

1) Learn about what investing in the stock market means, what's the nature of it and what to expect from it. I have two recommendations here:

1.1) jlcollinsnh's Stock Series: http://jlcollinsnh.com/stock-series/ He recently released a book (The Simple Path to Wealth) which is supposedly a better-edited version of the Stock Series. He's a rather optimistic guy, but what he says is not wrong. He stays away from investing in non-US markets, which is not the most common position among indexers.

1.2) A Random Walk Down Wall Street, by Burton Malkiel. It's an amazing book that everyone should read if they want to learn about the stock market. Many people recommend Bogle's books (he's the father of index investing), but I find them incredibly tedious to read.

2) Learn about the different investment accounts available to you - 401(k)/403(b)/457(b)s, IRAs, HSAs, taxable brokerage accounts. Each one receives different tax treatment and you should be familiar with that in order to avoid "tax drag" i.e. taxes slowing down the growth of your investments.

3) Another resource I highly recommend is the Bogleheads wiki: https://www.bogleheads.org/wiki/Main_Page. In particular, check out the following pages:

https://www.bogleheads.org/wiki/Bogleheads%C2%AE_investing_s...

https://www.bogleheads.org/wiki/Three-fund_portfolio

https://www.bogleheads.org/wiki/Tax-efficient_fund_placement

4) Don't obsess about it once you get started. After you've learned a few things it's tempting to start "tweaking" your investments here and there, but if you do that often you do yourself more harm than good. Invest your money then go have some fun :)


Thank you for the detailed answer!


Schwab, Vanguard.


That's a great point. I've always bought VTSMX, on the assumption that it's as close to "total US market" as one can get. Is anyone aware of downsides of VTSMX (excluding downsides of indexing in general)


This may fall into the category of "downsides of indexing in general", but even VTSMX, which is based on the CRSP index, isn't necessarily getting you the entire stock market in the U.S., which is something to be aware of, I suppose.

The criteria for inclusion in the CRSP index specify "a minimum total market capitalization of more than $10 million with a float that more than 10 percent of the total shares outstanding". So there is sub-micro stuff 'beneath' the index that's not included due to the $10M minimum, and others that aren't included because of the float requirement. Do you care? Probably not, but you might.

Also, I've periodically heard arguments against market-cap weighting, which is what indexes do (this is probably one of those "downsides of indexing" arguments). If you are not careful, with a couple of index funds you can end up really exposed to a handful of very large, and therefore highly-weighted, blue chips. But I can't think of another way of weighting within a whole-market index that would make sense.

The other thing that comes up a lot, mostly in tech circles, is that index funds (of course) don't give you exposure to the private market, and it seems that more and more tech companies are waiting a long time until they go public, such that at any given time a lot of growth is happening where most investors can't get in on it. The argument is that, if you are financially qualified, there are more opportunities out there for qualified/accredited investors on the private market. I don't personally agree with this if you're looking for an investment rather than a job as an investor, but you'll sometimes hear the argument get made.


I think people routinely over estimate the amount of money that VC funds are making.


No love for equal weight? RSP has some interesting performance characteristics. There is the Wilshire 5000 Equal Weight Index, but, alas, no fund tracks it.


I highly recommend most people, at least when they are young, don't put all their eggs into market cap weighted total market funds by getting at least some direct exposure to mid and small-caps. You can potentially leave a lot of growth on the table by being too heavily weighted towards the more conservative big boys(and conversely, lose a lot by not being so weighted towards them, but that's why you do it when you are young).


Not really? Go to http://quotes.morningstar.com/chart/fund/chart?t=VITSX&regio... and click on "Maximum" and compare to VFINX. The total market and S&P500 indices have tracked really closely for a long time. You're not missing out on much, if anything, by holding only the S&P500.


tcoppi is arguing against market cap weighting, which is the reason why VITSX is so close to VFINX despite containing other stocks.

If the total market is outperforming S&P 500, that means the companies not in S&P 500 perform better overall, so giving them greater weight than suggested by their relative market cap would have been beneficial.


Total market has outperformed slightly since 2008, but for a good period prior to that, the S&P500 was outperforming total market (also slightly). It's not super cut and dried.


The 5 year performance of VTI (the ETF version of that mutual fund) and SPY is .44% in favor of VTI. There is a better dividend yield on SPY though so you would have been better off there. Large companies dominate so adding in small caps doesn't really change things a ton. The two funds haven't diverged in a meaningful way in a very long time.


One downside of VTSMX is 0.16% expense ratio, compared to 0.05% for VTSAX (same fund, different class).


Which is still more expensive than SCHB.


It's too broad. When you buy everything, you buy the downsides of everything.


Hmmm... is anyone offering an index of indexes?


You can get a whole world index. MSCI offers an ETF like this (https://www.ishares.com/us/products/239600/ishares-msci-acwi...).


Vanguard's LifeStrategy funds are an index of indexes.


They're a fund of funds but not an index of indexes. An index of indexes would be composed of indexes weighted by how much money is invested in each. Vanguard's LifeStrategy funds have fixed allocations to each underlying fund.


Useful to know, thanks for the correction.


From the article: "Funds run by Vanguard hold roughly 6% of total U.S. stock-market value."

So index funds are not eating the world.

Most Wall Street traders underperform the market. Even the hedge fund crowd mostly underperforms the market. "A Random Walk Down Wall Street" is real.


Owning a few percent of a Fortune 500 company will probably get you a board seat, and a 10% stake probably makes you the single largest holder (especially ignoring companies still held by the founders/family like Wal-Mart or Google). Vanguard's current holdings makes them the single largest owner of Apple, Microsoft, and Exxon (the 3 largest companies in the S&P 500, I didn't check further). And that's just one of the firms offering index tracking ETFs.

Vanguard owning 6% of the entire US stock market value is huge. You could reasonably re-title this "Is Vanguard Eating the World" and be right if it wasn't for Blackrock and other ETF firms being close behind them.

Sources: https://finance.yahoo.com/quote/AAPL/holders?p=AAPL and similar pages.


But "Vanguard" is simply the sum total of all fund investors, since it has an inverted corporate structure.


In terms of using equity to exercise voting rights, you complete give up those rights when you buy into an index fund. So to a large extent, the voting policies of Vanguard and other index fund managers can matter a lot, especially if they are easily persuaded by activist investors.


That inverted structure is BS you can only vote for people proposed by the management company for funds and in turn those people will vote for management company appointments. Whoever started this whole thing is still controlling it you just have an illusion of control. "Own nothing, but control everything."


True, I got a little carried away with "Vanguard eating the world". I was just trying to get across the scale of 6% of the entire US stock market.


> "A Random Walk Down Wall Street" is real. reply

It's a real book, but it doesn't prove the market is random, nothing does as the efficient market hypothesis is just that, an unproven hypothesis lacking even enough evidence to become a working theory.

That certain funds consistently beat the market year in and year out for decades is enough to disprove the notion that markets are random; they're not.


The claim of the book is that you, as a regular investor, do not have access to better-than-market returns, not that they are not possible. Anyone who can provide better returns will claim the difference for themselves (in fees) rather than pass it on to you. Why would they give you free money?


Let's say that funds X, Y, and Z can regularly beat the market. Fund X then passes on better returns to its customers, and therefore gets more customers. Then Y and Z have to do the same thing, otherwise they lose customers. Simple competition.

Are you saying the above won't happen?


That doesn't prove a damn thing.

When so many people are playing, there's bound to be some that consistently win, just by chance alone. The book discusses this.



And there are statistics tests one can use to determine if one's performance meets those statistical parameters to be random. Many funds and managers beat it over the long term, such as Warren Buffet, but the vast majority indeed do not.


Warren Buffet usually invests to the extent that he has the power to change how the company is run. He usually uses that power.


In addition to that, there might be an effect due to the media hype around investments of Warren Buffet. People see in the news that Buffet invested in companyXYZ so they think that must be a smart idea and also invest in the same company and therefore driving the price higher...


Does that change my thesis at all?


I was just drawing the distinction between beating the market through passive investing (simple stock picking) vs. what Warren Buffet does.


Over any one year, sure, even over a few years, sure, but when you see consistent winners over decades in numbers that exceed what random chance would expect, it's foolish to still insist the market is random other that it being a good way to sell books. I know what the book discusses, and the book is an unproven hypothesis, it doesn't need to be disproven as it has never been proven in the first place.

That markets are random is a hypothesis only; one lacking sufficient evidence to declare it a theory.

No one has proven markets are random and that's where the burden of proof lies.


Show me an example of someone repeatedly beating the market, year after year, for decades.

Besides, even that is "only" a one in a million chance. How many people trade on the stock market?


From what I remember from the book, the claim is not that nobody can beat the market; it's that you can't distinguish them from lucky winners.

By the way, which funds have beaten the market for decades?


Renaissance Tech? Clearly at some level of expenditure you can beat risk/return of the market, but it doesn't necessarily scale either up or down. You need enough money to hire your army of PhDs, but not so much money that it starts to affect the market.

edit: heh, snap.


> it's that you can't distinguish them from lucky winners.

Jim Simmons doesn't agree, see Renaissance Technologies as an example. And time would week out lucky winners; luck isn't consistent over long time periods and this is just one example.


The RenTech Medallion fund is owned entirely by fund employees. It's not accessible to people who are not able to contribute to its success.


True, but not relevant to whether the market is or isn't random, which is the topic.


I think the argument is a little more complicated than that. It might not be enough to observe that active traders aren't outperforming the indexes, because, as the argument goes, passive indexing creates its own market forces that tend to favor incumbents and work against aspirants.


But maybe. Vanguard has 6%, Blackrock and Fidelity at 5% each, some of the other investment firms also offer index. I'll peg that all up, 45-50% of the investments are in some kind of index fund.

Lots of money and market push there as indexes.

Bogle said that there could be issues at the 90% level, so we are still pretty far away.

My issue is funds that are Index 500 or DJI average are set by someone else. Hence the huge number of funds that own Apple and can push on them. When they rebalances those indexes, it can be a traumatic event.

On the other hand, index funds are a way of playing par golf with your money every day.


People own a lot appreciated stock they don't really want to sell and take the tax hit on. EX: CEO/Founders etc.

So, the real question is what percentage of funds are index funds.


"Yet Mr. Fraser-Jenkins has a point. Index funds don’t set prices; they only accept the prices that active investors have already set. If everyone owned index funds, he says, “no one would be doing” the job of figuring out what securities are worth."

The situation described is clearly not a Nash equilibrium. If you have special, accurate information on the price of a security, then you're going to act on it. Why would no one be doing the work of pricing something if it's profitable? Sounds like actively managed mutual funds are getting antsy because people are starting to realize that they're getting screwed not going with index funds.


If everyone invested exclusively in index funds, and no one works to establish a market price for each individual component, the obvious thing to do would be to adjust indices to manage the portfolio based upon actual dividends.

All companies converge on the same P/E ratio, and the ratio of the index depends on how much investor money is chasing the overall productive activity of every [investable] company in the economy.

It wouldn't be the end of the world, by far.

But it is doubtful this will ever get even close to happening, because some investors will always be gamblers at heart, and if they learn that Coca-Cola is releasing a new beverage flavor, they will use the financial markets to make bets on whether it will be insanely popular or a colossal failure.


If one company's earnings are growing quickly, and another's is slowly shrinking, and they have the same P/E ratio, I'm likely to skip the index and buy the high-growth company directly.

If a company can reinvest earnings at a high rate of return, it's to the advantage of stockholders if it doesn't pay dividends. How much should the index weight it?


...illustrating why the price system will always be available to value things.

If there is no market trade price for a stock, the only way investors can realize value from owning shares is through dividends. Increasing the value of the company does nothing for the owners individually if shares for a specific company have no individually identifiable price. Everybody is buying and selling through the automated index funds, remember? The only way to get higher capitalization in the opinion of the fund robots is to issue better dividends. There's no one to sell to at a higher price, except the other robots, who all have similar valuation algorithms, and will need to sell the same amount as your fund robot in order to realize any gains.

But that is all absurd and moot, because there will always be a price, as long as two individuals are willing to move differently from the herd. As we are mostly humans in our market, that behavior is practically guaranteed. The outlier who thinks the stock is outperforming the whole market will buy from the outlier who thinks that the stock is underperforming. And their combined beliefs and opinions will create a price for it.

Ergo, index funds are not eating the world.

The fewer people there are that are willing to try to beat the funds or game their algorithms, the easier it will be for any one of them to succeed. So there will always be at least one.


Which makes me wonder whether there's a strategy that specifically takes advantage of mispricing by overuse of index funds.

First that comes to mind: small caps historically get better returns, and maybe that difference will be amplified by market-cap-weighted funds.

Picking stocks which are growing but not quite big enough to get into larger cap indexes could be another possibility.


An economist and a reporter were walking down the street when a $20 bill blows into their path on the sidewalk. The economist looks at it, smiles knowingly, then steps over it and continues walking. The reporter says, "Why didn't you pick up that $20 bill?" The economist replies, "If it was really a $20 bill, someone would have picked it up already."

By the economist's reasoning, someone already has a strategy to take advantage of index funds. Actually, a lot of someones already have every possible strategy to take advantage of index funds. So none of them really make significant returns, because the dead whale is eaten by a million scuttling isopods, each taking one or two bites before it's all gone. So the real money is in taking advantage of those guys, perhaps with fees or paid reports or little boxes that light up and go "ping".

Of course, just because all the free money is already being picked up, doesn't mean you will never catch a flying $20 bill if you decide to make a grab for it. No market is perfect, and there's always an opportunity to grab some free money somewhere.


Yep I read Random Walk on Wall Street too, a while back. More recently I read a stack of books on quantitative investing strategies, which referenced a lot of academic work. Turns out quite a few academics don't really believe in the EMH anymore; it's just not holding up to historical evidence. There are all sorts of factors that can make markets less efficient.


FULL DISCLOSURE up front - I work in the index/ETF business. I help maintain ~75 indices, many of which have ETFs linked directly to them.

That being said, I fully believe there will always be active investors. As others have mentioned, if there is an opportunity to make money in the market due to something like passive index funds being slower on the uptake, it will be made.

If I had to interpret the core argument being made here, it is basically that there is a fear of a positive feedback type scenario where money keeps getting dumped into companies simply because it always has. But it can be highly profitable to beat out the slow, passive money by doing your due diligence. For this reason, active management will always exist.

Also, I am fortunate enough to work on some of the more complex and interesting products in the industry (at least I believe so, haha). I can tell you that there are definitely sanity checks put in place for this kind of scenario. Most of it revolves around fundamental ratios built into these product methodologies (i.e. P/E ratio must be within a rational range, company must produce stable income for the past 5 years, etc.). More importantly, securities in these portfolios are frequently weighted (at least in part) upon those fundamental ratios. So if a company starts to deteriorate, the size of the position in the fund will be decreased. Much of what the article talks about seems to be negated by this and becomes a non-issue. I think those arguments would apply more to benchmark products which don't have those kinds of requirements. Then again, many benchmarks are used for exactly that - benchmarking - and aren't directly invested in. There are, of course, indices like the S&P 500 that have significant sums of money attached to them, but they are the exception, not the rule. Most index products deemed "investment-grade" are STRATEGY based, not benchmark based.

Basically, there is room in the market for both. I think we are simply seeing the progression towards a new equilibrium, nothing more. That equilibrium is where the new balance of those willing to take a higher risk meet those that want the less risky, low cost products that we provide. There is simply a much smaller portion of the population willing to pay higher fees and have a larger risk (but with possibly greater reward). And that is due in part to the fact that many money managers don't have the returns to keep people coming back. It's also due in part to people's mistrust of the market (and financial industry in general). They are simply allocating their money in accordance with their risk appetite.


This comment greatly improved my understanding thanks


Doesn't it seem self-limiting? At some point, if prices become totally irrational, wouldn't active investors profit by taking advantage of predictable index fund transactions?


This is an under-appreciated point... if 99 people leave money on the table, and the 100th person picks it up, we're back to efficiency in the aggregate.


Yeah, it's a bit like saying: "But what if all the animals in the ecosystem became helpless herbivores?"


What your saying sounds like the Grossman-Stiglitz paradox.

There will always be active investors. People will always think they know a way to succeed in the market that nobody else does. It's human nature. Plus, there will always be VCs, hedge funds, and other high-risk, high-reward investment vehicles used by the wealthy to add some spice to their otherwise conservative portfolios.

There may be fewer active investors than before, but that doesn't mean the market won't function.


>warned that index funds might grow to the point at which new investments could be massively mispriced.

This situation will be easy to spot from indicators like P/E ratio. P/E limited index funds will be new hotness and active investors should get better returns.

There is bigger problem than index funds and it's closet indexing. Many portfolio managers that claim to be active investors secretly follow their benchmark index without exactly replicating it. This is fraudulent behavior.


> There is bigger problem than index funds and it's closet indexing. Many portfolio managers that claim to be active investors secretly follow their benchmark index without exactly replicating it. This is fraudulent behavior.

As long as they can also provide competitive maintenance fees and tracking errors don't play against them, I don't see much of a problem. If they consitently do worse than the ETFs based on the same indexes with a similar risk profile, the market will eventually punish them for under-delivering.

If they only make a few picks that end up doing well, keeping the rest of the benchmark for a balanced risk profile seems sensible to me.

Please explain where the problem lies exactly?


>If they consitently do worse than the ETFs based on the same indexes with a similar risk profile, the market will eventually punish them for under-delivering.

The problem is with consistency and eventually. Definition of closet indexing is active share below 60%. These funds are not consistently worse if the observed period is just few years.

Since actively-managed funds usually perform worse than index funds in long term, closet indexing should be able to keep up with actively managed fund with same costs.

Selling funds is mostly marketing. Asset management firms have several funds and they sell the one that randomly performs better than it's benchmark in some short period of time (1-3 years). Very badly performing funds are merged into other funds and new funds are created.

Research shows that 15-20% of European large-cap funds could be labeled as closet indexers and 15% of the net assets in equity mutual funds sold in the United States are closet indexers.


This article incorrectly assumes that smart investors would sit around and do nothing if most people invest in index funds.


> If businesses are to be able to raise capital by selling shares to outsiders, “you need a deep market of active investors willing to take a view on the valuation of the company,” Inigo Fraser-Jenkins, head of quantitative strategy at Bernstein in London and lead author of the “Worse than Marxism” report, told me this week.

And that's a terrible investment strategy to ask of the average layman, the people who are concentrating on index investing.


> Because corporations know that, says Prof. Heemskerk, coziness and complacency may arise. “If you have only long-term investors, how do you keep management on their toes?”

We've a ways to go before the pendulum has swung enough in that direction. I'm more concerned about the tendency to seek short-term profits at the expensive of long-term investment in today's Wall Street CEOs.


> But, he adds, that would require indexing to grow immensely from today’s levels. Probably not until passive funds are at least 90% of the market could such chaos arise, he argues.

That's a pretty hypothetical scenario, isn't it? Index funds, ETFs in particular, are a brilliant idea that allows ordinary people to participate in the success of market trailblazers.

If it wasn't for index funds most people wouldn't be able to make reasonable investment decisions because they're not investment bankers who deal with that sort of business on a daily basis. Even investment bankers fail with their investments most of the time. It's usually just the few successful investments or things like arbitrage that balance out the odds.

Ordinary people usually neither have the knowledge nor the resources to do investments this way, so index funds probably are the best option for accumulating wealth over a period of time.


> A report this past week from investment firm Sanford C. Bernstein, titled “The Silent Road to Serfdom: Why Passive Investing Is Worse than Marxism,” warned that index funds might grow to the point at which new investments could be massively mispriced.

In which case the actively managed funds which identify the mispriced assets would start making money and attract investors again. You know there's trouble brewing in the industry when mutual funds are trying to sell investors on "it's good for the economy!"


> That’s largely because index funds trade so much less often than active managers. On a typical day, only 5% to 10% of total trading volume comes from index funds, says a Vanguard spokesman.

I'm surprised the author omitted it, but can anyone comment whether this is different for robo investors (Wealthfront, Betterment) vs a traditional index fund like Vanguard?


Robo advisors are like meta index funds.

They give you the canned advice that your local Financial advisor gives you, minus the quarterly meeting and phone therapy when the market goes down, and plus some automated intelligent handling of capital gains to reduce your tax exposure.


Robo-investors offer you a portfolio of funds (could be a mix of mutual and index) run by companies like Vanguard.


“The Silent Road to Serfdom: Why Passive Investing Is Worse than Marxism”

good Lord


Can high-frequency traders replace active investors in an ideal world. Ideally, the price should be the best estimate of the value of the company based on all publicly available information. When new information is released, high frequency traders should rush to profit from the discrepancy. Further, they can market make based off their knowledge of the stock's true value. However, this business should face increasing competition until it becomes a low-margin business. I don't see any inherent reason, active investing should be super profitable. In the end, it is just another business like any other.


Besides the issue of corporate ownership / concentration, index funds are also increasing the risk of a market crash. One of the selling points for index funds is that they supposedly offer great diversification and this might be true in normal times but in a financial panic people will pull out of index funds and drive correlations to 1. E.g. if there's a crash in health care, panicked investors won't just be pulling out of health care they'll be pulling out of the market as a whole.


I'm not sure that a market crash is a prima facie bad thing. Market crashes often precede or accompany economic recessions but I'm inclined to believe that they are a symptom or result rather than a cause. An economic recession is a bad thing due to increased unemployment, among other reasons.

If there is a real contraction in the health care sector and people react by pulling out of the market entirely then that is a good thing for people looking to put money into the market; the rest of the market is on sale (relative to its "real" value). Even if the market is made up entirely of indices, the market as a whole will end up appropriately priced. Those who panic sell will lose money but the index will bounce back assuming non-health care assets truly were undervalued.


Pulling out of large managed funds would have similar effects.


Yes, but this does not diminish the value of the companies in the long term. Remember that index funds are an investment vehicle for decades, not months.


Only if enough people stick with the long term. If everyone tries to hop off the boat for the short term, it can be a self fulfilling prophecy that growth will slow for a decade or more as the market hit effects real business returns.


This is probably the best article ever written about the efficient market theory and passive investing. It was written by Warren Buffett in 1984. http://www8.gsb.columbia.edu/rtfiles/cbs/hermes/Buffett1984....


Not an expert but seeing the quick rise in popularity in anything makes me nervous. eg. Index funds and ETFs. When Apple is the Number 1 holding of all index funds, and investors are blindly driving up aapl stock becuase they continue to want 'index' funds.. how do we protect ourselves and our economy from a major reset/correction?


Is it accurate to say that the difference between index and non-index funds is that a) index funds don't trade as much and b) index funds publish their components?

Is there any reason an "active" manager cannot behave like a passive manager? Is index investing just outsourcing the stock picking?


So people won't be able to make money selling their stocks to other people. Maybe corporations will simply adapt and provide dividends that appropriately compensate for the price of the stock?


Isn't the answer an index of hedge funds?


Not a big deal. As Index funds trade more, than more opportunity for traders. It'll balance itself out.


Active investing serves a valuable purpose.

10 years ago, everyone wanted to be in the hedge fund industry. Today, it's tech startups. Having worked in both fields, you encounter the same folks running from funds to startups.

Hedge fund fees probably move to 1 and 10 over the coming decade, but active investing and price discovery are very valuable. For those willing to do the work, small and midcaps still can generate alpha. However, it will require spending many hours traveling and meeting with management and being engaged in the sector virtually nonstop (trade shows, conferences, reading articles/news).

I think generalist active investing will go away, but sector focused active investing will remain.


"warned that index funds might grow to the point at which new investments could be massively mispriced"

Could, he says. lol.


no

Is Betteridge's law of headlines always correct? Click here to find out!


It's 99% correct. If something sensational were substantively true, it would be stated, not asked.


Even better: "Does this Headline Conform to Betteridge's Law?"


When a headline is a question the answer is almost always no. This is no exception.


From the article: A report this past week from investment firm Sanford C. Bernstein, titled “The Silent Road to Serfdom: Why Passive Investing Is Worse than Marxism,”

"serfdom", "Marxism"... Let me guess: Libertarian Party propagandist.


> Let me guess: Libertarian Party propagandist.

Or just someone who is well-read and likes to throw in literary references.

~libertarian here: don't know him, but I'd bet he is what op thinks


Isn't active investing a zero sum game? Imagine a market with only two people and an average ROI of 7%. If then somebody has a 10% ROI through active investing then it follows that other one who also invests actively only gets a 4% ROI%.

With passive investing you invest in a stock because you think the company's value will grow in the future. They are building a new factory or entering a new market, etc... The added value will be represented by a higher stock price which you can sell to obtain your investment returns.

>The social function of active management, in a capitalist society, is that it seeks to direct capital to its most productive end, facilitating sustainable job creation and a rise in the aggregate standard of living.

What if an actively managed fund gives me a 10% return but a 4% fee and a passively managed fund gives me a 8% return but only a 1% fee? Wouldn't the passively managed fund be the most productive from the investors point of view?


I'm libertarian-ish, and I still have no clue how passive investing has anything to do with Marxism.


To me, it's more saying "Paying us money is the way to freedom!"
