Stocks On the Move: Sothebys, Trivago, and Omnicom Group Inc.

U.S. stocks are mixed, following today's disappointing housing data. Among specific equities in focus today are auction house Sothebys (NYSE:BID), Wall Street freshman Trivago (NASDAQ:TRVG), and marketing stock Omnicom Group Inc. (NYSE:OMC). Here's a quick look at what's moving BID, TRVG, and OMC. 

• BID is trading 8.8% higher at $41.77 -- and just off an annual high of $42.66 -- after receiving some positive analyst attention from Cowen and Company, which upgraded BID to "outperform" from "market perform," and hiked its price target to $45 from $38. BID is up 61% so far this year, and currently sits above the $41 mark that acted as a ceiling to the shares in August. A number of Sothebys short sellers may be sweating, with short interest up 6.8% over the last reporting period, and shorted shares now accounting for 21.7% of BID's float, which would take almost four weeks of trading to cover, at BID's average daily volume.
  
  
• Hotel search platform and Expedia Inc (NASDAQ:EXPE) spinoff TRVG is having a promising Wall Street debut, with shares trading at $11.88, after opening on Thursday at $11.20 per share -- above its initial public offering (IPO) price of $11 per share. Trivago also lowered the number of its American depositary receipts to 26.1 million -- down from the previously planned 28.5 million -- to raise $188 million. Earlier the shares touched $12.43 before retreating back below the $12 level.

• OMC is down 2.4% at $85.87, after this morning's announcement that two of the company's units received subpoenas from the U.S. Department of Justice Antitrust Division, which is examining video production practices in the ad industry. Omnicom Group Inc. said it planned to fully cooperate with the investigation. OMC is up more than 13% so far in 2016, and touched a record high $89.66 earlier this week. Some put players are likely cheering today's pullback, with OMC's 10-day put/calll volume ratio at the International Securities Exchange (ISE), Chicago Board Options Exchange (CBOE), and NASDAQ OMX PHLX (PHLX) of 3.96 sitting in the top 84% of its annual range.
