I hold shares of the same mutual fund at two separate brokerage houses. When I sell a fund from one brokerage, can i use their cost basis? I hold shares of the same mutual fund at two separate brokerage houses. Therefore, I have an Average cost basis from each of the two brokerages. If I sell from Brokerage A, can I use my average cost basis from Brokerage A as is, or do I need to figure my overall average basis from the 2 brokerage firms? |
