Oppenheimer can't get knocked off its bullish stance on J.C. Penney (NYSE:JCP), saying the increased promotional stance the retailer is taking will pay dividends this holiday season and down the road in 2013. Despite the optimism, the general view from retail analysts is that even if J.C. Penney stops the bleeding, it's still going to be hard to recapture the customers it lost to Macy's (NYSE:M) and Kohl's (NYSE:KSS).
