Using the data from the prior two questions and found in tab , run a time-series regression for each asset to measure the auto-regressive (AR) coefficient over 1- month and 1-year periods. For annual measures, calculate cumulative annual returns ending in December of each year. a. Compare your AR coefficients from each regression. What do you conclude from the monthly versus annual AR(1) coefficient differences? b. Calculate annual mean returns as your estimate for prior year returns. Combine this with your estimated intercept and AR(1) coefficient to predict returns for 2017.
