Urban Outfitters offered a better-than-expected snapshot of its fourth quarter, saying in a filing after the market close that same-store sales in its retail business are "high single-digit positive" so far this quarter. Janney on Friday said consensus was for a mid-single digit gain, given strong Black Friday showings at the company's namesake and FreePeople shops. Shares jumped 7% to $39.59 premarket.
