Covariance_{DECK, S&P 500} = Σ(R_DECK,t–R_DECK)×(R_{S&P 500,t}–R_{S&P 500}) ÷ (71 – 1)
= 1,590.05 ÷ (71 – 1)

Systematic Risk (β) Estimation

Variance_DECK	77.69
Variance_{S&P 500}	25.32
Covariance_{DECK, S&P 500}	22.72

Calculations

¹ Correlation coefficient_{DECK, S&P 500}
= Covariance_{DECK, S&P 500} ÷ (Standard deviation_DECK × Standard deviation_{S&P 500})
= 22.72 ÷ (8.81% × 5.03%)
= 0.51

² β_DECK
= Covariance_{DECK, S&P 500} ÷ Variance_{S&P 500}
= 22.72 ÷ 25.32
= 0.90

³ α_DECK
= Average_DECK – β_DECK × Average_{S&P 500}
= 3.26% – 0.90 × 0.90%
= 2.46%
