1 相関係数INTC, S&P 500
= 共 分散INTC, S&P 500 ÷ (標準偏差INTC × 標準偏差S&P 500)
= 26.48 ÷ (12.74% × 4.37%)
= 0.48
2 βINTC
= 共 分散INTC, S&P 500 ÷ 分散S&P 500
= 26.48 ÷ 19.11
= 1.39
3 αINTC
= 平均INTC – βINTC × 平均S&P 500
= 0.27% – 1.39 × 1.14%
= -1.30%

3 E(RINTC) = RF + βINTC [E(RM) – RF]
= 4.84% + 1.39 [17.37% – 4.84%]
= 22.20%
