下列关于资本资产定价原理的说法中，正确的是( )。

A．股票的预期收益率与β值线性正相关

B．无风险资产的β值为零

C．资本资产定价原理既适用于单个证券，同时也适用于投资组合

D．市场组合的β值为1

答案

参考答案：A,B,C,D

解析： 本题的主要考核点是资本资产定价模式。
Ki=Rf+β(Km-Rf)
由上式可知，股票的预期收益率Ki与β值线性正相关；又由β值的计算公式：βJ=rJM[*]可知，无风险资产的σJ为零，所以，无风险资产的β值为零；市场组合相对于它自己的σJ=σM，同时，相关系数为1，所以，市场组合相对于它自己的β值为1。资本资产定价原理既适用于单个证券，同时也适用于投资组合。

SOX is an alternative (71) for XML. It is useful for reading and creating XML content in a (72) editor. It is then easily transformed into proper XML. SOX was created because developers can spend a great deal of time with raw XML. For many of us, the popular XML (73) have not reached a point where their tree views, tables and forms can completely substitute for the underlying (74) language. This is not surprising when one considers that developers still use a text view, albeit enhanced, for editing other languages such as Java. SOX uses (75) to represent the structure of an XML document, which eliminates the need for closing tags and a number of quoting devices. The result is surprisingly clear.

（72）处填（）。

A．command

B．program

C．graphic

D．text
