[size=80%]l这个是我们老师的课件。是在学了SML后给的一道题

Youare advising a very risky software firm on the right cost of equity to use inproject analysis. You estimate a beta of 2.0 for the firm and come up with acost of equity of 18%. The CFO of the firm is concerned about the high cost ofequity and wants to know whether there is anything he can do to lower his beta.

[size=80%]lHowdo you bring your beta down?

[size=80%]lShouldyou focus your attention on bringing your beta down?

我个人想的是，BETA是受选的参考指数和指数的选区区间（月度，年度）的影响。这里BETA可以通过用另外的指数来使它变小。

第二个问题就不明白了。感觉就是beta本来就是系统风险，没有办法避免的。还是解决成本比较重要，所以不用把中心放在把beta变小上。

我这种想法对不啊?请各位牛人指教一下。
