Convio was one of the market's biggest winners. Blackbaud will be buying the provider of fundraising software in a deal that values Convio at $16 a share.

Sears Holdings has been the hottest component of the S&P 500 three weeks into 2012. Despite bleak holiday sales metrics posted late last year, speculators are hoping that helmsman Eddie Lampert will take the company private.

Net 1 UEPS Tech took off after the payment and transaction services provider landed a five-year deal to distribute social grants in South Africa.

Dangdang continues its strong bounce three weeks into 2012. Encouraging GDP news out of China -- showing that the world's most populous nation grew at an 8.9% clip in the fourth quarter -- helped propel shares of the Chinese online retailer higher. The GDP news shows that China's growth may be decelerating, but clearly not at a problematic clip.

Finally, we have Cree overcoming an uninspiring quarterly report when a couple of analysts stood up for the company's future potential.
