我认为是buying opportunity, 包括今天ASML带着semi sell off其实有点似曾相识发生过，上次也证明仅仅代表ASML specific issue。catalysts除了TSM，还有potential SMCI pre announcement window 18-24天 before earning, 也很有可能announce split。IWM total market cap加起来不如meg7里面的个股，所以很难justify 完全从big cap tech/semi rotate进small cap这样的theme, 我还是维持semi/big tech会一起rally together with broad market
