$Rocket Lab(RKLB.US)$Tesla(TSLA.US)$Taiwan Semiconductor(TSM.US)To be more specific, just these three. Buy big when it falls big, buy small when it falls small. The 343 buying method recommended by Little Rocket can be changed to 532. Catch the rebound. Little Rocket will definitely break 100 this year. For long-term or short-term, choose TSMC. It's no problem. The same goes for Tesla: buy big when it falls big, buy small when it falls small. If you're not greedy, catching the rebound is very profitable.
