portfolio theory

1. Markowitz efficient frontier risk return model

2. Sharpe CAPM capital allocation line (CAL) most efficient one: tangent to efficient frontier 

CAL vs. CML(capital market line)

E(Rp) = Rf + [E(Rm) - Rf]/dM * dp

SML vs. CML

Portfolio evaluation 1-2 cml 3-4 sml(related to pricing)

1. Sharpe ratio slope of CAL: (Rp-rf)/dp higher Sharpe ratio means better performance.

2. M^2 portfolio outperforms market M^2 = dM* (E(Rp) - Rf)/dp - [E(Rm)-Rf]

greater the shoe ratio, greater M^2 is.

3. Treynor measure = (Rp-rf)/beta p - measure of systematic risk  单位系统性风险的超额收益 横坐标为beta

4. jenson's alpha = rp-rf - beta p(rm-rf) - measure of non-systematic risks
