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.
