NEW YORK ( TheStreet) -- Two retailers saw large stock swings on Tuesday reflecting each company's positioning in a difficult apparel retail environment. Urban Outfitters ( URBN) shares plummeted after the retailer disclosed that third-quarter sales comparisons were only in the mid-single digit range so far, below analysts' expectations. The sales comments were disclosed Monday evening in Urban Outfitters' quarterly regulatory filing with the Securities and Exchange Commission. "A mid-single digit comp increase is below the first half trend of positive 9% and will likely be viewed negatively by the Street," wrote Stifel analyst Richard Jaffe in a research note last night. "We would be buyers of the stock in weakness." Shares were falling 10.3% to $38.30. Jaffe said he believes sales are up between 3% and 5% at Urban Outfitters, but faring better at its two other brands Anthropologie and Free People, up between 6% and 8% and between 18% and 20%, respectively. "In our opinion, the outlook for the balance of the quarter is favorable. The current floorsets at Urban, Anthropologie and Free People look attractive and seem to be well received by customers. Additionally management is focused on several operational initiatives (improved inventory turnover and increased speed to market) that allow URBN to buy product closer to need, allowing them to make better product decisions and thus minimizing markdown risk," the note said. "We believe strength should continue throughout 2013." The analyst reiterated his "buy" rating and $48 for his 12-month stock target price, but trimmed third-quarter earnings estimates and full-year estimates each by a penny to 47 cents a share and $1.93 a share. Wall Street is looking for Urban Outfitters to post earnings, on average, of 46 cents a share for the quarter and $1.93 for the year, according to Thomson Reuters. "Although its customer base skews older, Urban Outfitters seems to have caught the same bug plaguing the teen retailers, as decelerating comps ... are to blame for URBN's lower comp outlook," wrote Wells Fargo Securities analyst Paul Lejuez in a research note on Tuesday. He rated Urban Outfitters at "outperform."
