We have five really big movers after the close this Thursday. The big gainers and losers today in the after-hours are as follows: Audience Inc. (NASDAQ: ADNC); Infoblox Inc. (NYSE: BLOX); Mattress Firm Holding Corp. (NASDAQ: MFRM); Smith & Wesson Holding Corp. (NASDAQ: SWHC) and Sturm, Ruger & Company Inc. (NYSE: RGR).

Audience Inc. (NASDAQ: ADNC) is the red-headed step child today. This stock is being gutted after an SEC filing shows that a product transition related may no longer be used by Apple Inc. (NASDAQ: AAPL). Apple giveth, Apple taketh away! Shares rose 4.7% to $18.86 on the day, but shares are down 46.7% at $10.05 in the after-hours session.

Infoblox Inc. (NYSE: BLOX) closed up almost 4% at $23.39 today, but shares are down about 10% at $21.00 in the after-hours. The company bet on revenues but its annual view looks light.

Mattress Firm Holding Corp. (NASDAQ: MFRM) is giving back on much of its progress, and its losses are now almost twice the day’s gain. Shares rose 5.5% to $32.45 and the after-hours reaction is -10.8% at $28.95 after announcing earnings (weak guidance) and after announcing an acquisition of Mattress Xpress.

Smith & Wesson Holding Corp. (NASDAQ: SWHC) gained over 3% today but shares are cruising to a new 52-week high in the after-hours after reporting big earnings gains and after a higher outlook. Dirty Harry rules once again … “Smith, Wesson, and I” … Shares closed at $9.00 and the stock is up 20% at $10.80 after the close with more than 500,000 shares since its halt was released. The gain is enough to lift Sturm, Ruger & Company, Inc. (NYSE: RGR) by 4.1% to $48.65 after the close.

Stay tuned for Friday’s unemployment data.
