If a few days ago you bought US stock Hynix here because I mentioned it at 150 (and you got in), the rebound has already reached the initial expectation. You can choose to take profit now—this was just a quick grab for some gains, and there might be opportunities to re-enter later. Although I feel a bit regretful, as I mentioned before, complete the buy-sell cycle and then reassess. If it was your own judgment, then make your own decision.
