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.
