I mean $200 is $200 imo. Say you have $12,000 in a stock and it goes up $200-$250 shortly after you buy it. Anything wrong with selling it? I don't other than just making sure the accountant doesn't charge too much to process the taxes on it. Usually I'll hang onto a stock longer than a 2 or 3 days and see what it does and i'll wait until it has a $500 or $600 dollar gain before selling it.
Your question is meaningless without context.
I mean, $200 is $200.
But it might be a 0.01% gain in a true portfolio, in which case, it’s noise...
Nothing at all to celebrate, worry over, or sell.
