After sinking to lows last seen in 2009 in the market's January lull, URBN shares have ripped off 80 percent-plus runs on a couple of earnings beats and record results. The impetus isn't anything scintillating – just better operational performance. Among other things, Urban Outfitters has been improving its inventory management via upgrades to its supply chain, which in turn bolsters margins. That profitability helped fuel an all-time best 66 cents per share for the second quarter, as well as a record $891 million in sales.
