I've calculated the Mean return, variance of returns, covariance and correlation coefficient for 3 stocks and also S&P500

	Company A	Company B	Company C	S&P500
Geometric Mean Return	0.688%	0.301%	-0.002%	0.163%
Variance of Returns	0.0017	0.004	0.0010	0.0001

	A vs B	B vs C	C vs A	S&P vs A	S&P VS B	S&P vs C
Covariance	0.0003008	-0.000030	0.0004271	0.0000878	0.0000095	0.0000874
Correlation Coefficient	0.3636	-0.0469	0.3323	0.2651	0.0572	0.3399

Based on the above calculations, compare the results and discuss the risk return characteristics and performance of the stocks and the index.
