I purchase stocks over a period of three years through an employee stock plan. I also reinvested my dividends (DRIP). Every time I had enough money Etrade would purchase a stock for me, usually about one a month. Last June, I sold my stock and now have to report a cost basis for the stocks sold. This is absolutely a nightmare as i have about 36 different trades over the last three years. How on earth do I calculate this . I know about first in/ first out and all the other things you are supposed to do, but I find this impossible. HELP!!!!!!!!!
