Please help with this practice problem I am having difficulty with. I will leave a review and thumbs up, thank you in advance!

Portfolio Theory Suppose stocks and bonds have the following properties: 0 Assets Stocks Bonds E[7] 9% 20% 4.5% 5% 12 The correlation between the two asset classes is Pec The T-bill rate is 3%. The typical institutional portfolio (split 60/40 between stocks and bonds) has similar dollar investments in stocks and bonds, but gets a highly disproportionate risk exposure from stocks. If you were selling a "risk parity portfolio (i.e., one that got similar risk exposures from each of the asset classes, a popular strategy/sales pitch from sophisticated money managers), what strategy would you recommend? That is, what's the Mean Variance Efficient (MVE) portfolio of stocks and bonds?
