NEW YORK ( TheStreet) -- Stocks posted gains Thursday, aided by strong corporate earnings and good manufacturing data, as investors shrugged off disappointing jobs data. After the close, Google ( GOOG) reported earnings that beat expectations. The Dow Jones Industrial Average added 21 points, or 0.2%, to 11,145. The S&P 500 gained 1 point, or 0.1%, at 1212, while the Nasdaq went ahead by 11 points, or 0.4%, at 2516. After the close of trading, Google said thriving ad sales helped it earn $6.76 per share, excluding items, in the first quarter and boosted revenue by 23%, topping forecasts on both counts. Shares added 1.1% during the session to finish at $595.30, but were selling off in extended hours trading with some reports citing increasing costs as a worry for investors. Also, CEO Eric Schmidt did not participate in the after hours earnings call. The day's economic news offered a mixed view of the recovery. Initial jobless claims unexpectedly rose to 484,000 and industrial production grew at a sluggish pace in March. Regional manufacturing indices, however, showed continued strength.
