Does anyone else hate looking at new stocks when you are already 95% fully invested?

I invest in individual tickers, mostly microcaps or small caps, My selection is doing pretty good, but the one with most of my money is about 35% away from my target and I should sell if it reaches that. So I keep looking at new tickers, maybe I buy a 300-1000 shares, but can't really afford more. And if I buy one more, I will be out of free cash.But these sorts of stocks you need to pay closer attention than some stock like NVDA, because they could easily lose a big % lose overnight. So it I buy I feel like I need to watch every detail, it would be hard to do with too many tickers. The part I hate, look at a promising company, but can't buy unless I sell a stock that is going up while the stock I am watching is basically either going sideways or declining. But even the declining ones are a good ticker, just got too over bought in the short term. So I end up watching some of those promising stocks go up, sometimes really do well. An example today was Hyliion Holdings, hyln, which today rocketed up over 40%, it was in my ticker file so I see it all the time. Do may others do the same, and how do you deal with missing out?
