The index model has been estimated for stocks A and B with the following results:

RA= 0.03 + 0.85RM+ eA RB= 0.01 + 1.55RM+ eB

The standard deviation of the market index is 27%; the residual standard deviation of the error terms for stock A is 22%; the residual standard deviation of the error terms for stock B is 30%.
