Using the log-return data provided for the five assets, describe the observed performance of these assets over the past year. In particular, report the sample mean return, median return, sample standard deviation, and observed range (maximum minus minimum). Based on these summary statistics, assemble a brief (one page at most) comparison of the observed returns for these assets. In particular, which assets had the highest or lowest average return? Do you get different results based on median returns? Which assets exhibited the highest variability (largest range or standard deviation) or lowest variability (smallest range or standard deviation)?
