为什么 SP500 可以一直涨，因为它会”止损“

不好好表现的就被踢出去。比方这个：TRHC。所以要跑赢SP500 不容易。

• ZimVie (ZIMV) will replace Tabula Rasa Healthcare (TRHC) in the S&P SmallCap 600, effective prior to the opening of trading on Wednesday, March 2.
• S&P 500 constituent Zimmer Biomet (ZBH) is spinning off ZimVie in a transaction expected to be completed on March 1. Post spin off, Zimmer Biomet Holdings will remain in the S&P 500. Tabula Rasa Healthcare is no longer representative of the small-cap market space.
