解释:
老师,CAL 和EF的切点不是何老师上课讲的M点吗?不就是以市值为权重的market portfolio吗?
NO.PZ2018070201000058 问题如下 The point of tangenbetween the capitallocation line (CAL) anthe efficient frontier of risky assets most likely intifies the: A.optimriskly portfolio. B.market portfolio. C.globminimum-varianportfolio. A is correctThe optimrisky portfolio is the point of tangenbetween the capitallocation line anthe efficient frontier of risky assets.. 如题,按照我自己的理解,CAL是risk-free asset 与EF的切点连成的线,切点是risky asset portfolio,CML是risk-free asset 与EF的切点(切点是market portifolio)连成的线,是众多CAL中的最优解,只有这条线与Investor Utility有切点,但切点有没有定义,麻烦您解答一下,谢谢
没太明白,这个值得Between是不是指中间的gap
讲义里老师说optimportfolio是infferencurve和Efficient Frontier的切点,但是后面又说optimportfolio 是CAL和EF的切点,到底哪个是对的?
