All funds are loaned at the risk-free rate Rf , one gets a portfolio at the point Rf in Fig. , a portfolio with zero variance and a risk-free rate of return Rf . If instead one progressively invested a percentage x of all funds in the risky assets, one would follow the line Rf g, where the point g corresponds to investing 100 % in a portfolio of risky assets. Points to the right of g correspond to investing more than 100 % by borrowing at the risk-free rate. 10) But the portfolio g in Fig. 1 is not mean-variance efficient.
