I felt this. I bought a well-known controversial EV stock quite low; my plan was to make at least 33% on it. After a year, I'd made 400%, but I was struggling to click the "Sell" button. Some greed surfaced from somewhere, and it took me a couple of days to cancel the greed and sell the stock, making 12X what I hoped to the year before.

The stock has since gone up a lot more, but my dad told me: Buy low, and Sell too soon.

If I made 400% on something, I would probably sell half of it, and keep another half at least for a year. That way, both my safety and greed would be satisfied.

(But this is more about psychology than math. For some people this would be the worst option, because if the thing would lose value, they would blame themselves for not selling everything when they had the opportunity, and if it would gain even more value, they would blame themselves for not waiting with everything. So it would be lose/lose from their perspective.)
