Q2 sharp ratio fully segmentation下的SRi是否可以计算出来呢？ 利用ICAPM model : betai=rou(I,m)*deltai/deltam= rou(I,m)*deltai /(ERm-Rf)/SRm=0.39*0.14/[(0.072-0.031)/0.36]=0.479 ERi-Rf=betai*(ERm-Rf)=0.479*(0.072-0.031)=0.019656 Sri= (ERi-Rf)/deltai=0.019656/0.14=0.1404 从而 fully segmentation 下为 0.4× 0.1404× 0.14=0.0078624 Fully integrated risk premium下为0.6× 0.14 × 0.39 × 0.36=0.1182 (wight* rou*deltai*SRm= wight*beta*deltam*SRm) All= fully segmentation + Fully integrated risk premium=0.01968
