Suppose that the index model for stocks A and B is estimated from excess returns with the following results: R_A = 5.0% + 1.3R_M + e_A R_B = -2.0% + 1.6R_M + e_{B M} = 20%; R-square_A = 0.20; R-square_B = 0.12 What is the covariance between each stock and the market index? (Calculate using numbers in decimal form, not percentages. Do not round your intermediate calculations. Round your answers to 3 decimal places.)

Stock A=

Stock B=
