If bought 50 shares of XYZ stock at $10.00 per share back in 2005. It splits 2 for 1 when it gets to $50.00 per share. I now have 100 shares worth $25.00 per share. Since the stock is not doing well in 2010 I sell 50 shares to try to cut some of my loss. I sell at $5.00 per share. I know this is entered as Long Term on Schedule D but am confused as to what the cost basis total should be? (Column E).

Thanks
