It may have been a mixed quarterly report out of hhgregg, but investors warmed up to the consumer electronics retailer beating analyst profit targets and sticking to its earlier guidance for the entire year. There's been a sharp drop in sales of TVs, DVD players, and Blu-ray players, and it's obviously not just hhgregg feeling the pinch.

Radian Group was radiant after posting its first quarterly profit this year. Analysts were braced for a loss out of the provider of mortgage insurance coverage.

Hurricane Sandy left behind a horrendous path of destruction, but with so many homes still waiting for electricity to return, is it any wonder to find Generac Holdings serving up powerful guidance? The company makes power generators, and those are going to be a big seller now and in the future as folks gear up for the next inevitable storm.

Dendreon moved higher after posting a 27% spike in sales of its late-stage prostate cancer treatment, Provenge. The popular biotech's recent restructuring should reduce expenses by 20%.

RIM climbed on reports that dozens of telecom companies are starting to test new BlackBerry devices running the company's potentially game-changing mobile operating system. Naturally, RIM has a lot riding on the success of BlackBerry 10. It remains to be seen if the company can regain the momentum that it has lost over the past two years to iOS and Android devices, but telecom companies testing the new platform make it likely that the company will finally be able to hit the market with BlackBerry 10 early next year.
