The single-index model for stock i is Ri = 0.01+1.5RM + ei. The single-index model for stock j is Rj = 0.02+0.8RM + ej. The standard deviation of the market return is σM=0.2, the standard deviation of ei is σei=0.3 and the standard deviation of ej is σej=0.4. 1. Calculate the systematic risk, firm-specific risk, and total risk of stock i.
