Suppоse yоu оbserved thаt people tend to purchаse stocks which hаve been on the rise and sell stocks which have sudden price drops. Anecdotal evidence suggests that stocks which have the higher returns in the past 3 months tend to perform better (namely, have higher returns in the following month) than those which have the lower returns in the past 3 months do. Define a factor Pi, t at time t as the past 3-month return of stock i from 3 month ago to present time t. Please describe a statistical analysis procedure to test whether the factor Pi, t is statistically significant in influencing the monthly asset returns at time t across ALL stocks. Describe a sorting procedure (as discussed in the lecture) to test whether a profitable portfolio strategy (equal-weight in each stock of the portfolio) can be formed based on the factor Pi, t with monthly re-balancing of the portfolio.
