According to the presentations in class, "Quarterly Trading Patterns of Financial Institutions," which of the following statements are the results or conclusion of the article? I. SEC requires institutional investors with total investments greater than $100 million to report their holdings quarterly. This gives incentive for institutional investors to window-dress their portfolios (by dumping losing stocks and loading up on winning ones) in order to make their portfolios more attractive to investors. II. Winner institutions engage more actively in window-dressing their portfolios for quarter end reporting than loser institutions. III. External money managers generally sell more extreme loser stocks than internal money managers before the reporting dates. IV. Institutions that manage assets on behalf of clients have greater tendency to window-dressing their portfolios. a. I and II Ob. I, II, and I c. 1, III, and IV Od.
