$Palantir Technologies Inc.(PLTR)$what a lot of people try to do is to time the market. But as always, timing in the market outweighs timing the market. For example if you took profit at $25 previously and you're thinking of buying back when the stock price drops but the stock shoots up to $28. So now you're afraid that you'll miss the boat and buy back in at a higher entry price. And guess what, now it's back to $27 instead. Moral of the story, don't let your emotions control you. Buy in stocks with good fundamentals and just enjoy holding it!
