Suppose stock returns can be explained by the following three-factor model:

R_i = R_F + ₁F₁ + ₂F_{2 3}F₃

Assume there is no firm-specific risk. The information for each stock is presented here:

	1	2	3
Stock A	1.75	.75	.50
Stock B	.82	1.35	.70
Stock C	.83	.33	1.44

The risk premiums for the factors are 7.1 percent, 6.3 percent, and 6.7 percent, respectively. You create a portfolio with 20 percent invested in Stock A, 20 percent invested in Stock B, and the remainder in Stock C. The risk-free rate is 4.2 percent.

What is the expression for the return on your portfolio? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)

What is the expected return on your portfolio? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)
