計算
1 相関係数MPWR, S&P 500
= 共 分散MPWR, S&P 500 ÷ (標準偏差MPWR × 標準偏差S&P 500)
= 32.85 ÷ (10.75% × 5.40%)
= 0.57
2 βMPWR
= 共 分散MPWR, S&P 500 ÷ 分散S&P 500
= 32.85 ÷ 29.16
= 1.13
3 αMPWR
= 平均MPWR – βMPWR × 平均S&P 500
= 2.52% – 1.13 × 0.67%
= 1.76%

3 E(RMPWR) = RF + βMPWR [E(RM) – RF]
= 4.69% + 1.13 [13.79% – 4.69%]
= 14.94%
