我在notes上没找到依据，不过在官方课本上找到了 第四本 216页

 

可惜我怎么看不明白

 

thus，asset allocation is very important decision。

across all fund ，the asset allocation decision explains an average 40% of the variation in fund return。

for a single fund ，asset allocation decision explains 90% of the fund's variation in return over time and slightly more than 100% of the average fund's leverl of return.

 

有没谁能帮忙解读下 谢谢了

对于所有的fund来说，资产分配决定了40%的variation

对于单个的fund ，资产分配决定了90%的variation

 

但是“slightly more than 100% of the average fund's leverl of return.”是啥子意思哦？
