>If I know for a fact that a company is about to collapse and I establish a short position, will anybody notice? It depends on a lot of factors, but I could make an assload of money on puts without nudging the market.

Assuming you are the only person who knows for sure that this company will collapse, technical analysis is the wrong tool to use and all other strategies, experts, big money players will also fail.

Assuming you aren't the only person who knows for sure that this company will collapse the price will reflect this knowledge.

>It's much like trying to predict a fire by watching a crowd running away and hit the fire alarm. You didn't predict the fire and you can't have predicted the fire. Maybe you could have noticed one person booking it for the exit and follow along, but you still didn't know what was happening and were going on blind faith.

It's nothing like that at all, and reasoning with analogy is pointless because the discussion becomes about the analogy not the issue at hand. But I will try. If people running away is people selling stock, it doesn't matter if there is a fire or not. Selling stock impacts price regardless of if the event is real or not. And as you know, having been in a building where the fire alarm was activated, people don't rush to the exists. Some small number leave right away. The vast majority won't enter the building. The remaining people look to others and as more leave the momentum builds until the mass moves out.

And once the fire department arrives and gives the ok they will go back in. But since we are talking about stocks, not all buyers won't be waiting for that. They'll have put their money elsewhere, money may go back into the stock slowly. Obviously this won't work on the top 3 most popular stocks in a raging bull market that everyone is paying attention to. In that case, people will be waiting to jump back in.
