The beta of the risk-free asset is zero, and the weight of the risk-free asset is one minus the weight of the share, so the b of the portfolio is: â¢ Ãp = x W(1.18) + (1 â x W)(0) = 1.18 x W â¢ So, to find the beta of the portfolio for any weight of the share, we simply multiply the weight of the share times its beta.
