3. Create at least 5 changes in the original portfolio parameters of returns, standard deviations of returns, and correlations among returns (e.g. change the correlation between the returns U.S. stocks and International stocks from 0.87 to 0.50). Make the changes in parameters one at a time. so they are relative to the original parameters. 0 Comment on the way each change in the original portfolio parameters affects the returns and standard deviation of returns of the portfolio, and the reason for that effects. (i.e. Does the effect make sense?) 4. Create at least 10 portfolios by varying the weights of the 5 funds in the portfolios, leaving as is the original average returns, standard deviations of returns, and correlations. (Make sure that the weights add up to 1.) o Display each portfolio as a dot on the graph of the efficient frontier below
