We have many after-hours movers after earnings and other reported events.  We are tracking moves in Broadcom Corporation (NASDAQ: BRCM), Buffalo Wild Wings, Inc. (NASDAQ: BWLD), Keynote Systems, Inc. (NASDAQ: KEYN), LDK Solar Co., Ltd. (NYSE: LDK), MIPS Technologies, Inc. (NASDAQ: MIPS), Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN), RF Micro Devices, Inc. (NASDAQ: RFMD), and SuccessFactors, Inc. (NASDAQ: SFSF).

Broadcom Corporation (NASDAQ: BRCM) was one we were having mixed emotions in ahead of earnings.  In the current quarter, sales were put in a range of $1.75 to $1.85 billion and that was a disappointment.  Shares are down over $3.00 or more than 8% at $37.13 on more than 2.2 million shares in the after-hours.

Buffalo Wild Wings, Inc. (NASDAQ: BWLD) beat earnings substantially at $0.81 EPS versus a Thomson Reuters figure of $0.73 EPS.  Same-store sales were up and it is opening 100 new locations.  For some reason the company did not introduce “The Ring Stinger” as the hottest wing sauce available.  Shares are up 4.7% at $63.30 on more than 50,000 after-hours shares. 

Keynote Systems, Inc. (NASDAQ: KEYN) blew out earnings at $0.29 EPS versus $0.21 estimates; shares are up 9.9% at $23.35 on more than 32,000 after-hours shares.

LDK Solar Co., Ltd. (NYSE: LDK) lowered guidance after having closed up on the day by more than 3%… The company lowered revenue guidance by about $100 million in the first quarter but reaffirmed its 2011 range.  Shares are down 4.55% at $10.90 on more than 2 million shares traded in the after-hours session.

MIPS Technologies, Inc. (NASDAQ: MIPS) is getting drilled after turning in $0.09 EPS versus $0.10 EPS estimates, but lower guidance is the real killer.  Shares are down 12% at $9.40 on more than 365,000 after-hours shares. 

Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) is not an earnings play but it feels like one… The company turned in positive results with Sonfi-Aventis (NYSE: SNY) showing that the Phase III VELOUR trial evaluating ZALTRA in combination with the FOLFIRI chemotherapy regimen versus a regimen of FOLFIRI plus placebo met its primary endpoints of improving overall survival in the second-line treatment of metastatic colorectal cancer.  Its shares are up 7.9% at $56.25 on more than 250,000 after-hours shares. 

RF Micro Devices, Inc. (NASDAQ: RFMD) had a 23% drop in revenue  and now the company sees a “flat to down 5%” revenue figure this quarter.  RF chips and components aren’t universal winners, apparently.  This one is down about 3.5% at $6.10 on nearly 300,000 after-hours shares. 

SuccessFactors, Inc. (NASDAQ: SFSF) won but lost in its cloud-based business execution software solutions… The company SuccessFactors beat earnings estimates, guided Q2 revenues above consensus and it raised 2011 guidance.  The company also announced that it was spending $290 million to acquire Plateau Systems for its leading learning management system, a Next Generation Portal technology, and CaaS- Content as a Service.  SuccessFactors had a $3.15 billion market cap. The stock is down 8% at $37.05 on more than 230,000 after-hours shares.
