Absolutely nothing wrong with slowly selling AMD.Glad I got some NVDA at a cheap price, but wish I bought more. That said I bought a bunch of AMD in the $10-$15 range so can't complain too much.
It's hard to know how to get out of stocks that have huge gains, my strategy with AMD is to slowly sell out of it over time and put it into index funds, but it's tempting to hang onto when you have such a big winner. Big hit on taxes too with those types of gains, which is another consideration.
I have to decide myself if/when I actually sell any NVDA/AMD/TSM/ASML. It will ultimately depend on what my overall portfolio looks like (if at the time, the current valuation of my entire portfolio is at a level where early retirement is possible much earlier, I would strongly consider selling certain positions in tech and crypto to lock in those gains).
