Question: Derive the efficient frontier using domestic equities, bonds, real estate, international equities, and emerging markets. (Hint: Use Solver. In setting the objective function and the constraints, do not permit short-sales, and recall that the goal is to choose the portfolio weights that minimize the level of portfolio risk, given some level of expected return. Start with the level of portfolio expected return equal to that of 5.5%, and then lower this constraint in 0.5% increments until you reach 10%)
