Stocks closed mixed in the final hour after dipping above and below the flatline for much of the day. Bank of America (BAC) is reportedly cutting dozens of jobs in its trading and banking divisions. The firm has committed to trimming expenses amid a drop in trading revenue. Sales in that division dropped around 5% over the third quarter.
