Systematic Risk (β) Estimation

Variance_ABBV	56.20
Variance_{S&P 500}	9.77
Covariance_{ABBV, S&P 500}	14.15
Correlation coefficient_{ABBV, S&P 500}¹	0.60
β_ABBV²	1.45
α_ABBV³	0.72

Calculations

¹ Correlation coefficient_{ABBV, S&P 500}
= Covariance_{ABBV, S&P 500} ÷ (Standard deviation_ABBV × Standard deviation_{S&P 500})
= 14.15 ÷ (7.50 × 3.13)

² β_ABBV
= Covariance_{ABBV, S&P 500} ÷ Variance_{S&P 500}
= 14.15 ÷ 9.77

³ α_ABBV
= Average_ABBV – β_ABBV × Average_{S&P 500}
= 1.63 – 1.45 × 0.63
