The portfolios in the minimum variance set are called frontier funds. For a given level of risk, only those portfolios on the upper half of the eﬃcient frontier are desired by investors. They are called eﬃcient funds. A portfolio w∗ is said to be mean-variance eﬃcient if there exists no portfolio w with µP ≥. WebFeb 17,  · The conventional method for portfolio optimization is mean-variance portfolio optimization, which is based on the assumption that returns are normally distributed. For example, a one-day 99% CVaR of \$12 million means the expected loss of the worst 1% scenarios over a one-day period is \$12 million. Moreover, CVaR is also .
