description: "A few ultra-small cap stocks: $Swarmer(SWMR.US) surged 520%, this kind of meme stock really isn't something normal people should touch. The two tech stocks in my hands, $Sidus Space(SIDU.US) and $SMX Security Matters(SMX.US), one fell nearly 3%, the other directly turned green by 8%. Whatever I buy doesn't move, and whatever I don't buy keeps rising every day. $Sidus Space(SIDU.US) and $Solaris Energy Infrastructure(SEI.US), these hype-driven stocks are also flying, the market looks exactly like a game of musical chairs. Honestly, right now I'm just afraid of being one step too slow, and then when the hype passes, I become the naive investor. I can only be a bit more zen, just watch the excitement and not follow the trend 🙈"
