13.1 The Capital Asset Pricing Model in Brief Developed in the 1960's by Sharp,and independently by Lintner,and Mossin It answers the question What would equilibrium risk premiums be if people had the same set of forecasts of expected returns,risk,and correlations and all chose their portfolios according the principles of efficient diversification (Refer to chapter12) THE COURSE OF FINANCE 2017 SPRING SJTU

Two Assumptions Investors forecasts agree with respect to expectations,standard deviations,and correlations of the returns of risky securities. Therefore all investors hold risky assets in the same relative proportions Investors behave optimally In equilibrium,prices adjust so that aggregate demand for each security is equal to its supply THE COURSE OF FINANCE 2017 SPRING SJTU 6

CML and Market Portfolio Since every investor's relative holdings of the risky security is the same,the only way the asset market can clear is if those optimal relative proportions are the proportions in which they are valued in the market place that proportions are called Market Portfolio THE COURSE OF FINANCE 2017 SPRING SJTU

CML and the CAPM CAPM says that in equilibrium, any investor's relative holding of risky assets will be the same as in the market portfolio Depending on their risk aversions, different investors hold portfolios with different mixes of riskless asset and the market portfolio THE COURSE OF FINANCE 2017 SPRING SJTU 8
