It sucks because a lot of the loses in the FTA could've been avoided. The highest gain and lowest lost of the SPY respectively have been 16% and 20%. As a personal rule any stock I purchase basically has a stop loss of 20%. As for the gain, I automatically sell after a 50% gain. How much more could you want?

edit: this is in the context of day trading

If everyone used stop losses, they wouldn't work for anyone. You need someone else to buy your share for you to sell. There has to be a bag holder.

When engaging in options trading, startup investments, penny stocks, and other Black Swan strategies, you can be in a situation where you most all your money 90% of the time, but 10% of the investments have a 100x return. If you pursue this risky strategy, you need to be able to hold on in the face of volatility and sky-high gains.

I wouldn't recommend this strategy to anyone who doesn't have Vulcan-level discipline over their emotions, but it is a valid investment strategy.

I agree, but from FTA someone took out a 12% loan and got in at $234. The price ended up closing around $360 a day or two later representing a 50% increase - considering the person took out a loan, seemed like a no brainer to me. ymmv

re: 50% gain, why not use a trailing stop loss at that point? If I'm trading/investing it's to make money so I want as much as I can get.

I agree in general but GME was highly volatile and execution is not guaranteed with a trailing stop loss, I think in general you're correct but I was talking about the anecdotes specifically in FTA.
