OpenTable (NASDAQ:OPEN): Citigroup says that while OpenTable’s third-quarter and full-year revenue for 2013 and adjusted EBITDA guidance missed expectations, implied fourth-quarter outlook may prove too aggressive. The firm keeps a Sell rating on shares with a $58 price target following the company’s second-quarter results.
Onyx Pharmaceuticals (NASDAQ:ONXX): Jefferies downgraded Onyx from Buy to Hold, citing its valuation, but raised its price target for shares to $132 from $104. The firm sees limited upside from current levels given the likelihood of a buyout deal closing between $140 and $145 per share.
