An investor has $100,000 to invest in four assets. The expected annual returns, minimum and maximum amounts with which the investor will be comfortable allocating to each investment, and risk factors are shown in the accompanying table. Assume that the investor will tolerate a weighted risk per dollar invested of at most 1.0. Experiment with the accompanying portfolio allocation model to attempt to find the best solution that maximizes the expected annual return and meets the total weighted risk constraint.
