計算
1 相関係数TXN, S&P 500
= 共 分散TXN, S&P 500 ÷ (標準偏差TXN × 標準偏差S&P 500)
= 27.21 ÷ (6.96% × 5.28%)
= 0.74
2 βTXN
= 共 分散TXN, S&P 500 ÷ 分散S&P 500
= 27.21 ÷ 27.91
= 0.98
3 αTXN
= 平均TXN – βTXN × 平均S&P 500
= 1.21% – 0.98 × 1.16%
= 0.07%

3 E(RTXN) = RF + βTXN [E(RM) – RF]
= 4.74% + 0.98 [14.86% – 4.74%]
= 14.61%
