Calculations
1 Correlation coefficientEMR, S&P 500
= CovarianceEMR, S&P 500 ÷ (Standard deviationEMR × Standard deviationS&P 500)
= 14.30 ÷ (5.69% × 3.29%)
= 0.76
2 βEMR
= CovarianceEMR, S&P 500 ÷ VarianceS&P 500
= 14.30 ÷ 10.84
= 1.32
3 αEMR
= AverageEMR – βEMR × AverageS&P 500
= 0.42% – 1.32 × 0.80%
= -0.63%
Expected Rate of Return
