请问这个题目对应讲义的哪里呢

问题如下：

A float-adjusted market-capitalization-weighted index weights each of its constituent securities by its price and:

选项：

A.

its trading volume.

B.

the number of its shares issued.

C.

the number of its shares available to the investing public.

解释：

C is correct.

"Float" is the number of shares available for public trading.

考点：float-adjusted market-capitalization-weighted index

这道题目的考点是float-adjusted market-capitalization-weighted index 的定义。以市值为权重，即是以“股价*总股本”为权重，而Float-adjusted是要调整为以流通股市值为权重，即“股价*流通股数量*”。
