Yes yes, survivorship bias, but the problem is actually interesting in several aspects:
1. On an individual level, it's impossible to distinguish between survivorship bias and doing things right. If you are the surviving one, did you do things differently or did you just get lucky? In a coin-toss competition, the answer is obvious. When it comes to stocks, it's not.
Because:
2. The general (academic) consensus to differentiate between luck and skill when it comes to investing is: Can you be profitable for a long period of time? But do you really need to prove yourself over and over that you have the skill? What if you had the skill only once, to predict one certain event and have tremendous gains with it? Apparently, this is considered "luck" and not "skill" when it comes to investing. Which I find odd.
Add the nonlinear utility of money: Your first million makes the biggest impact on your life, especially if you earn it early in life. Buying an ETF sets you up for a good retirement (probably, maybe), but the GME stock picking YOLO might put you on a different trajectory.
3. When it comes to finance and investing, we all know the academic view: passive investing / buy & hold is king, you can't predict the winners. All true of course, but the problem is: there is no resolution to this. You can say that, in hindsight, buy & hold returned X% on average over the last 50 years, but have to warn that "past performance is no indication for future performance". And ultimately, you can calculate your true performance only if you realize profits to do something with it in life or if you are about to die.
So, on an individual level, you have two choices:
- Buy and hold a passive index fund and hope that the performance of the last X years is indicative for the future performance, because that's how the stock market works (or whatever).
- Expose yourself to luck/chance/positive black swans by doing some skilled or unskilled stock picking that has potential to put you on another trajectory in life.
- Expose yourself to luck/chance/positive black swans by doing some skilled or unskilled stock picking that has potential to put you on another trajectory in life.
If the goals to expose yourself to luck, why not just purchase lottery tickets then?
