Losses and taxes

I lost quite a bit of money due to cutting losses last night. I checked the withholding tax statement earlier, but if you think about it carefully, instead of this loss, 20% tax will not be applied to the next profitable stock sale, right?

When I calculated it, it seemed like I would be charged about the same amount of tax as the loss, so I calmed down my mind just a little bit.

Of course, you can't get a sense of it until you actually experience it.
