Calculations
1 Correlation coefficientHPQ, S&P 500
= CovarianceHPQ, S&P 500 ÷ (Standard deviationHPQ × Standard deviationS&P 500)
= 14.35 ÷ (10.53% × 2.87%)
= 0.48
2 βHPQ
= CovarianceHPQ, S&P 500 ÷ VarianceS&P 500
= 14.35 ÷ 8.23
= 1.74
3 αHPQ
= AverageHPQ – βHPQ × AverageS&P 500
= 1.77% – 1.74 × 0.96%
= 0.10%
