问题如下：
Two individual investors with different levels of risk aversion will have optimal portfolios that are:
选项：
A. below the capital allocation line.
B. on the capital allocation line.
C. above the capital allocation line.
解释：
B is correct.
The CAL represents the set of all feasible investments. Each investor’s indifference curve determines the optimal combination of the risk-free asset and the portfolio of all risky assets, which must lie on the CAL.
请问这里说的是无差异曲线和cal的切点为optimal portfolio, 前一章学的时候又说无差异曲线和EF的切点也是optimal portfolio? 有点混乱
