Aeropostale, Inc. (NYSE: ARO) closed down 1.1% with the market today but shares are sliding hard after the dreaded fears came true in earnings: higher prices leading to lower profits.  Shares are down 6.5% at $23.01 on nearly 500,000 shares in the after-hours session.

Clean Energy Fuels Corp. (NASDAQ: CLNE) is actually up after earnings if you can believe it considering it is a nat-gas fuel for truck companies.  T. Boone Pickens is proud.  Shares are up by 4.6% at $13.60 on over 142,000 shares in the after-hours.

Clearwire Corporation (NASDAQ: CLWR) is lower after the decided to step down for personal reasons.  Really?  Shares were up 6.9% at $5.75 in regular trading but the stock is down by 2.4% at $5.61 on only 4,000+ shares after the close (shares were halted on the news).

Energy Conversion Devices, Inc. (NASDAQ: ENER) is getting pounded, bruised, and scolded… The solar player is cutting capacity due to incentive cuts in France and Italy (and likely elsewhere).  We have been concerned about this long before the Middle East erupted.  Shares are down a sharp 24% at $2.40 on over 330,000 shares in the after-hours session.

GenVec, Inc. (NASDAQ: GNVC) showed a narrower than expected loss at -$0.01 EPS and sees cash burning of only about $5 to $7 million for 2011.  Shares are up by 7.7% at $0.45 on only 4,200 shares in the after-hours.  Keep in mind that this is a penny stock so it can go any direction for any reason.

Lime Energy Co. (NASDAQ: LIME) is an unknown company to most and it is trading higher after earnings reports were above plan and with guidance.  Shares are up 8% at $5.37 on about 17,000 shares in the after-hours session.

National Semiconductor Corporation (NYSE: NSM) is down marginally after earnings with shares down 1.1% at $14.00 on 366,000 after-hours shares traded.  What is unusual is that the move is so little in this issue.

Zumiez, Inc. (NASDAQ: ZUMZ) is one that was expected to stay high after such cold weather earlier in winter but an earnings warning is killing shares.  The stock is down 6.5% at $26.34 in the after-hours.
