Flash Sales Site Zulily Has a Flash Surge

The top gainer at midday this Tuesday is flash sales site Zulily Inc (NASDAQ:ZU), up an impressive +40.99%. The company reported a Q4 non-GAAP EPS of $0.10 after close on Monday, up from $0.03 a year ago and significantly above the expected $0.04. Tiger Global holds a stake in the company.

At a distant second is Kindred Biosciences Inc (NASDAQ:KIN), the price of which increased +11.64%, continuing its post-IPO rally. Both Seth Klarman and Thomas Steyer have positions in Kindred, a clinical-stage biopharmaceutical company focused on products for pets. KIN is up +102.01% YTD.

Rounding out today’s list is Groupon Inc (NASDAQ:GRPN). The daily deals platform surged +8.62% midday today, its investors breathing a sigh of relief. GRPN, also a Tiger Global pick, is down -28.69% this year.

Allied Nevada Gold Slips a Bit

The biggest loser midday today is Lumos Networks Corp (NASDAQ:LMOS), down -10.22%. A provider fiber-based network services in the Mid-Atlantic region, LMOS reported Q4 2013 and full-year results that failed to impress the market as several of its business units declined. George Soros has a small 0.12% allocation in Lumos.

Sliding -6.99%, Apollo Investment Corp. (NASDAQ:AINV) dipped today as well. A business development company that invests in middle-market firms, this Leon Cooperman pick announced a public offering of common stock today. This means more stock on the market in more hands, the dilution of current shares, and a need for more cash. The Street recently downgraded its stock rating on cash flow from operations issues.

John Paulson bet Allied Nevada Gold Corp. (NYSEMKT:ANV) (TSE:ANV) comes in last on today’s list of losers, its price falling -6.38%. The company has had an impressive run so far in 2014, up +59.68% YTD, so today’s dip is likely a result of investors grabbing some profits.
