(e) Continue to use the restricted covariance matrix of part 2c. What happens to the MVE weights if you impose that all the portfo- lios are zero alpha using the values fer beta from part 2d? (In other words, set the expected returns for the small-cap and value portfolios to those predicted by the CAPM while using the esti- mated market expected return and a risk-free rate of 2%.) What happens to the MVE weights if you now add some of the alpha's back? For example try increasing the pertfolio expected returns from the CAPM values (zero alpha case) by adding in half of the alpha's frOm part 2d
