Calculations
1 Correlation coefficientDECK, S&P 500
= CovarianceDECK, S&P 500 ÷ (Standard deviationDECK × Standard deviationS&P 500)
= 22.72 ÷ (8.81% × 5.03%)
= 0.51
2 βDECK
= CovarianceDECK, S&P 500 ÷ VarianceS&P 500
= 22.72 ÷ 25.32
= 0.90
3 αDECK
= AverageDECK – βDECK × AverageS&P 500
= 3.26% – 0.90 × 0.90%
= 2.46%
