The return of a portfolio is the weighted average return of the securities which constitute the porfolio. Here you invest equal amounts in both the securities, weight will be 50%.
Stock | Weight | Expected Return (%) | Weight*Expected Return |
portfolio | 0.50 | 12.00 | 6.00 |
Risk free asset | 0.50 | 2.00 | 1.00 |
Portfolio Return = Weight*Expected Return
= 6+1
= 7%
Since the weights are same, it can also be calculated as average of returns.
