24/7 Wall St.

24/7 Wall St. has identified many of the key stocks on the move for day traders and active traders. We have included a brief summary of the news causing the move and added Tuesday evening and Wednesday morning trading data if applicable. These are some of the top movers and shakers for Wednesday.

Computer Sciences Corp. (NYSE: CSC) posted a rise in earnings, aided by lower costs and improved margins from a year ago. Its stock has recovered handily from the turnaround days, and shares were up almost 6% in the evening trading session on Tuesday, and they are indicated higher on Wednesday as well.

Finisar Corp. (NASDAQ: FNSR) was up almost 20% in thin volume after-hours trading on Tuesday night once its halt was released. This may mark a 52-week high for the stock, with a gain of 15% to $22.00 in early Wednesday trading.

First Solar Inc. (NASDAQ: FSLR) shares were down almost 8% on Tuesday after a disappointing earnings report, despite a collaboration with GE. Shares are down 8.2% at $42.90 in early bird trading on Wednesday.

Glu Mobile Inc. (NASDAQ: GLUU) looked good and above estimates on the surface for its most recent quarterly earnings, but unfortunately it lowered sales estimates and expects a loss in the coming quarter. Glu shares are down 8.7% at $2.52 on Wednesday.

Medifast Inc. (NYSE: MED) saw its stock down 5% in evening trading on Tuesday after the weight loss player had soft sales and guided expectations lower. Shares were still indicated down about 5%, but volume has not yet started.

Nanosphere Inc. (NASDAQ: NSPH) is not exactly a household name in molecular diagnostics, and apparently it needs better name recognition for boosting sales. Its sales were disappointing and the stock was down almost 18% at $2.40, and now we have indications down around $2.35 in Wednesday trading indications.

Nuance Communications Inc. (NASDAQ: NUAN) is challenging a 52-week low after guidance for the year is coming in light on the speech-recognition software leader. Shares were down more than 6% at $18.10 in late Tuesday trading, against a 52-week low of $18.00. The last price was still down almost 6.4% at $18.10, so maybe the prior 52-week low can hold,

Pixelworks Inc. (NASDAQ: PXLW) showed that its second-quarter revenue rose by 15.5% due to increased sales of chips for both projectors and TVs. Shares were up 26% at $4.50 in the Tuesday after-hours session, but we would warn that volume is not as active and a wide spread may have amped the gain. Now we have shares up a whopping 44% at $5.15, and volume has become active as a result.

Zillow Inc. (NASDAQ: Z) posted a loss after charges and expenses rose and shares were down 10% at $81.50 in the after-hours session. Zillow still managed top-line growth, but the stock is trading down 9.25% at $82.30.
