I'm not much is yet known about omicron, but a few countries announced they will be closing their borders again soon. I'm up 40-60% on some Tech stocks, should I take profit? I entered the market in July 2020, after nearly all of the recovery had occurred since Feb 2020. If there's going to be another big dump, I'd like to capitalize on it. (S&P 500 $S&P 500 Index(.SPX.US)$ is up 40% since July2020, so I at least beat that.) $Advanced Micro Devices(AMD.US)$ $Intel(INTC.US)$
