Stocks kept to a tight range Friday as the indexes added small gains. The Nasdaq and the S&P 500 rose 0.2% each, while the small-cap Russell 2000 popped 0.8%. The IBD 50 gained 0.3%. Volume rose across the board. If bulls were looking for hope this week, they found it in the way the indexes recovered from Monday’s whipping. The Nasdaq opened the week with a 1.3% loss and then reduced it to a sliver.
