Consider the two (excess return) index-model regression results for stocks A and B. The risk-free rate over the period was 7%, and the markets average return was 15%. Performance is measured using an index model regression on excess returns.

	Stock A	Stock B
Index model regression estimates	1% + 1.2(rM rf)	2% + 0.8(rM rf)
R-square	0.641	0.469
Residual standard deviation, (e)	11.4%	20.2%
Standard deviation of excess returns	22.7%	27.1%
