**Abstract:**
We propose to compute the implied expected returns from several candidate mean-variance efficient portfolios, exploiting the fundamental relation between the expected returns, covariance matrix and the corresponding set of mean-variance efficient portfolios. Over the 1987-2012 period and for the universe of S&P 100 stocks, we find that a mean-variance efficient investor would have been willing to pay between a 1.7% and 4.2% management fee to switch from mean-variance investing using implied expected returns from the market capitalization weighted portfolio to mean-variance investing using the implied expected returns from the equal-risk-contribution portfolio.
