4. For the Markowitz model in Example 14.10, deter- mine how the minimum variance and stock alloca- tions change as the target return varies between 8% and 12% (in increments of 1%) by re-solving the model. Summarize your results in a table, and create a chart showing the relationship between the target return and the optimal portfolio variance. Explain what the results mean for an investor. 4.
