The CAPM Formula The capital asset pricing model (CAPM) provides the required return based on the perceived level of systematic risk of an investment:The calculation of the required return The required return on a share will depend on the systematic risk of the share. ...
Betasused by CAPM to measure systematic riskare not observed:CAPM is a one-period model that treats a security’s beta as a constant, but researchers find beta can be changed in respond to firms’ investment in new industry, change in capital structure and so on. If betas change over time...

之前我们研究了如果只有n个risky asset的情况下,如何根据个人的risk aversion构建portfolio(hold over a single period)。那么如果加上risk-free asset,那么这个时候的市场上组成risky asset的portfolio就成了唯一也就是我们认为的market portfolio。based on these information,we can try to derive CAPM model here。
