Please use DATA STEP to calculate - 5-year cumulative U.S. market excess returns for every year between 1927 and 2020 that has a consecutive 5-year window. For instance,if one invests at the beginning of year t, the 5-year cumulative return is calculated for the years t,t+1,...,and t+4. Please calculate the compounded 5-year return as the cumulative return. - Then, calculate the probability of achieving a positive 5-year cumulative return and also calculate average annual return for the 5-year investment window. Are your analyses convincing enough to suggest to your clients that it pays off to take market risk and invest long term? *
