Target Corporation (NYSE: TGT ) shares are perking up in what looks like preparation for a breakout. Year-to-date, TGT has been rangebound with resistance near the $74-a-share level. This caps a long sideways range going back to early 2015 as the retailer has struggled with online competitors, tepid traffic growth, and profitability worries. Management is in the midst of a turnaround effort with store reinvestment underway.
