股票市场指数

问题如下：

A security market index represents the:

选项：

A.

risk of a security market.

B.

security market as a whole.

C.

security market, market segment, or asset class.

解释：

C is correct.

A security market index represents the value of a given security market, market segment, or asset class.

考点：security market index

股票指数可以代表：

A.市场风险。错。市场指数的风险（系统性风险）通常是由贝塔来衡量。

B错在它说的太片面了，只说了选项C的一个部分，它不光能代表整个证券市场的表现情况，还可以用来代表某一版块儿市场或衡量某大类资产收益情况。
