Quantum was the market's top-performing company, nearly doubling on favorable buzz over a plug-in hybrid version of the Ford's (NYSE: F) popular F-150 pickup truck it introduced during this month's Alternative Clean Transportation Expo.

Vermillion shares took off after a study showed that the company's OVA1 is a more effective blood test for detecting ovarian cancer than a rival test currently being recommended.

CKx isn't going to Hollywood. It's going to the Apollo -- Apollo Global Management, that is. The entertainment company behind the global Idol franchise that birthed American Idol and other regional incarnations accepted a buyout offer at $5.50 a share. It's a far cry from the company's own privatization efforts a couple of years ago, but it's a 40% premium to the stock's six-month average. 

ServiceSource delivered better-than-expected quarterly results in its first financial report since going public two months ago. Revenue climbed 43% for the cloud-based provider of enterprise software solutions. ServiceSource also posted a small adjusted profit. Analysts were banking on a quarterly deficit.

Dairy giant Dean Foods was no meandering cow after a promising Goldman Sachs update. Goldman sees Dean's bottom-line turnaround milking earnings growth of 72% in 2012 and 24% in 2013.
