请问一下，关于free float adjustment的结论，是否与课上讲的有出入？正确理解是：free float reflects true liquidity （but not lower liquidity？），thus makes index more investable？ 对吗？
另外，free float adjustment是作为non-investable stocks的一种解决方法？
谢谢您！

与课上讲的是一致的。假设一共有100股，其中40股限售。在free float调整之前，100股中只有60%是流通的, investable的。free float 调整后，剩下的60股 100%都是流通的, investable的， 所以是增加了流动性。“free float reflects true liquidity，thus makes index more investable”，这个理解是正确的。
free float adjustment可以理解为partial investable stocks的处理方法。non-investable的股票基本没有流动性了。

NO.PZ201809170400000201 Buffering makes inx benchmarks more investable (Statement 2) making inx transitions a more graanorrly process. 对于这句话的理解不够深入，请指点。 在之前听课的理解中，investible仅仅意味着“好买还是不好买”，也就是流动性问题。 而buffering解决的是“减少rebalancing”，也就是降低cost的问题。 这两件事不在一个层面上，为什么buffering能牵扯到investible？ 谢谢！

NO.PZ201809170400000201 把流通盘调整后（剔除），发现可以交易的难度提升了，意思不就是说流动性对于投资者不好了？
