The proportion borrowed at the risk-free rate can be obtained by solving: w_rf F1F1F1S1F1F1F10 E(R_rf)+ (1 - w_rf)F1F1F1S1F1F1F10 E(R_mkt)= 0.10%.Substituting the market and risk-free returns of 18% and 6% respectively yields w_rf0.06 + (1 - w_rf)0.18 = 0.10%,which can be solved to obtain a risk-free rate of w_rf= 2/3 or 66.7% (approximately).
