Subject: Just a complaint.
One of my screens picked NVDA about a year ago.

A month or so ago I sold it for a 100+% gain because it kept hitting nosebleed new highs and I was getting scared.
But it was still a screen pick the next month (June), so I bought it at the monthly rebalance. Up 11% from when I sold it, that I missed out on.

Now it's up 19%. Should not have sold it, at most should only have sold enough to rebalance.

Fear & emotions are not your friend in investing.

BRK.B is easier. Never on any screens, just buy it and forget it.
