As a rule, I hold until I NEED to money.....as I'm not smart enough to know what the market will do (I mean, I like NVIDIA a lot, long term)......but, we will need some money early next year, so I might lock it in. That said, I have a couple losers that I could sell, and take a tiny tax loss. Unless I love a loser, I usually sell those when I need cash, to keep the tax bill low. We are wondering what the new President and Congress will do to tax rates........and at some point, I'm going to have to start selling winners.....
