create a chart that shows how the efficient frontier may shift from a pre-crisis period to a new frontier during the crisis.

You will create two efficient frontiers on this chart, using different inputs.

Depict your results on a single graph where is on the horizontal axis and is on the vertical axis. Assume a risk-free return of .0025 per month. Use an expected return of 0.9% for stocks and 0.5% for bonds for both scenarios. For standard deviations and correlations, use the numbers from Slide 36 of Optimal Portfolios with Two Risky Assets (Does Diversification Work? Before and during the financial crisis) these will be different for each scenario. So, you should have the same mean returns for each scenario but use different standard deviations and correlations.
