Draw a picture of Markowitz’s mean-variance investment parabola. Label the Y-axis as E(R_P) for expected returns and X-axis as σ²_P for the variance of returns. Where is the minimum variance portfolio G? In your figure, show how Kolari, Liu, and Huang (KLH) (2021) located two orthogonal portfolios with equal time-series variance of returns: I ^∗ on the efficient frontier, and ZI^∗ on the inefficient boundary of the parabola. According to KLH, what defines the width or span of the parabola? Show this in your diagram along with the mean market return.
