Question

The following table contains the historic returns from a portfolio consisting of large stocks and a portfolio consisting of long-term Treasury bonds over the last 20 years. T-bills returns represent risk-free returns. Analyze the risk-return trade-off that would have characterized these portfolios. The following dataset is also available in Excel format in Module 3 Resources on Canvas. Returns in the dataset are in percents. For example, 31.33 means 31.33% per year.

1997	31.33	11.312	5.26
1998	24.27	13.094	4.86
1999	24.89	-8.4734	4.68

c. Estimate the Sharpe ratio of large stocks and long-term T-bonds, respectively. (Round your answers to 2 decimal places.)

d. Now assume that you have always invested half of your wealth in the stock and the other half in the T-bonds. Estimate the Sharpe ratio of your portfolio. (Round your answers to 2 decimal places.)
