However, he would like to retain an interest in the company. So, knowing that he needs to avoid the wash sale rules, when he sells the common stock on December 15 and deducts the loss on his return for the year, T. D. simultaneously purchases an equivalent amount of preferred stock in DLW Inc. On January 17 of the next year, he sells the preferred stock and repurchases DLW common stock. What do you think of his strategy from an ethical perspective? How do the wash sale rules apply when preferred stock is purchased? o What do you think of T.D.'s strategy from an ethical perspective? o What would you advise T.D. in this situation
