By David StermanThe S&P 500 is back near where it was a month ago. A surge into November was met by recent profit-taking as markets headed into the Thanksgiving holiday. In pullbacks like these, I like to scan the lists of losing stocks to see if any bargains get uncovered. I found three, all of which hit 52-week lows this week, and all of which are still solid long-term plays. The pullback in these names should set the stage for a much better 2011.
