I bought MPWR at $1,560, but I’m not sure if my timing was good. Any thoughts or advice?

I recently purchased shares of Monolithic Power Systems, Inc. (MPWR) at an entry price of $1,560 per share. While I remain optimistic about the company and the prospects for its products, I am currently feeling a bit hesitant and unsure whether this was an opportune time to enter the market. My primary objective is long-term investment; however, I am now weighing whether I should lock in some profits or continue to hold my position to see how things unfold. If you have in-depth knowledge of MPWR or have similar investment experience, I would greatly appreciate your advice and guidance! At this price level, should I hold, add to my position, or consider trimming my holdings? Thank you all for your help.
