Consider the two (excess return) index-model regression results for stocks A and B. The riskfree rate over the period was 5%, and the markets average return was 13%. 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% + .8(rM rf)
R-square	0.605	0.451
Residual standard deviation, (e)	10.8%	19.6%
Standard deviation of excess returns	22.1%	25.9%
