Calculations
1 Correlation coefficientAMAT, S&P 500
= CovarianceAMAT, S&P 500 ÷ (Standard deviationAMAT × Standard deviationS&P 500)
= 38.83 ÷ (11.43% × 4.97%)
= 0.68
2 βAMAT
= CovarianceAMAT, S&P 500 ÷ VarianceS&P 500
= 38.83 ÷ 24.73
= 1.57
3 αAMAT
= AverageAMAT – βAMAT × AverageS&P 500
= 2.68% – 1.57 × 1.22%
= 0.76%
