The weights of the original risky portfolio will stay the same because when combined with the fisk free investment the optimal combined portfolio will still stay on the same CAM.
For this reason on will take y, the amount invested in a risky portfolio and then multiply that number by the weights in the risky portfolio. The risk in the original portfolio will not change. Roberto have a much higher risk aversion coefficient of 4.3 than does Cathy A=.5 who has a low risk aversion and therefore is willing to invest in a much higher proportion of risky portfolio.
