NEW YORK ( TheStreet) - Facebook ( FB) reports its second-quarter results after market close on Thursday; its first since the company's eventful IPO in May. The social networker's shares have plunged more than 28% since the company's botched public offering, and there are concerns that this trend will continue. After selling so much stock at such a high valuation, the shares seem to have nowhere to go but down. Wednesday's weak second-quarter results from Zynga ( ZNGA) could also impact Facebook's results. The online gamer, which is a key Facebook partner, cut its full-year earnings guidance, citing "a more challenging environment on the Facebook web platform." Investors on Facebook's conference call will be also be listening for information on the company's attempts to exploit mobile, which are seen as key to its future. There has even been chatter that the Menlo Park, Calif.-baed firm could enter the smartphone market. Analysts surveyed by Thomson Reuters expect Facebook to report revenue of $1.146 billion and earnings of 12 cents a share.
