I think the biggest problem is people getting in with no exit plan. They see a bunch of people jumping in, but nobody really says when to get out.
I haven't made the most optimal moves but I'm ahead because I kept taking profits.
My first foray into the markets was 2008 where I ended up losing my ass in the crash. Dipped into Margin and everything. Stayed away from the market for 10 years. Got back in last year during the crash. I'm not up a ton, still licking my wounds from 2008, but I'm up a nice amount.
However, with everything at ATH, I sold out everything a couple weeks ago, only jumped back into the meme stocks because it was money sitting around & FOMO.
Everyone wants to feel they know better & not see red. Stubbornness gets in the way.
But now when I buy I typically have some mental triggers on when to sell.
Volume dipping, general sentiment, intuition, and dollar targets.
Thing with meme stocks is you know they are overvalued and you know it's going to crash, so you need to be a lot more aggressive with your exit plan. The tide turns so rapidly, you can't just sit on them.
