Calculations
1 Correlation coefficientSYY, S&P 500
= CovarianceSYY, S&P 500 ÷ (Standard deviationSYY × Standard deviationS&P 500)
= 29.70 ÷ (9.02% × 5.24%)
= 0.63
2 βSYY
= CovarianceSYY, S&P 500 ÷ VarianceS&P 500
= 29.70 ÷ 27.47
= 1.08
3 αSYY
= AverageSYY – βSYY × AverageS&P 500
= 0.69% – 1.08 × 1.07%
= -0.47%
Expected Rate of Return
