Formulas Used:-

Month	Portfolio Return	S&P 500 Return
January	0.058	0.06
February	-0.024	-0.033	R2	=CORREL(B5:B16,C5:C16)^2
March	-0.019	-0.013	Alpha	=INTERCEPT(B5:B16,C5:C16)
April	0.024	0.016	Beta	=SLOPE(B5:B16,C5:C16)
May	0.005	=0.2%	Average return difference	=B18-(E7+(E8*C18))
June	-0.01	-0.006	Average return difference (without signs) %	=B18-(E7+(E8*C18))
July	0.002	0.004
August	0.014	0.019
September	-0.005	-0.003
October	-0.035	-0.038
