When sentiment is all about hyping "this time is different," is it really different? The difference from 2000 now is that semiconductor profitability continues to improve, and AI is not just a concept but actually generating profits. Looking back at history is not about being bearish, but about facing risks squarely; there's no market that goes crazy forever. Paying attention to taking profits and securing gains is the scientific way. If you insist on chasing highs, then I have nothing to say. Staying in the market at this stage will definitely bring excess returns. As for when to exit, you decide for your own wallet, just keep an eye on the risks. 👀👀$Invesco QQQ Trust(QQQ.US)$SPDR S&P 500(SPY.US)$NVIDIA(NVDA.US)$Micron Tech(MU.US)$Spdr Select Tech(XLK.US)$iShares Semiconductor ETF(SOXX.US)
