LCA Vision was the last week's biggest winner, soaring 44% after posting a narrower deficit than Wall Street was eyeing. The Lasik vision-correction specialist posted a 27% gain in revenue on a healthy uptick in procedures performed.

Cynosure returned to profitability in its latest quarter, fueled by top-line popping acquisitions and a 90% surge in laser product revenue.

Penn Virginia struck optimism when Stifel Nicolaus upgraded the company. The analyst has a $7 price target on Penn Virginia.

Demand Media was clearly in demand. The online content creator with a knack for optimizing page views posted better than expected quarterly results. Demand Media also provided a rosy outlook where it sees revenue growth actually accelerating as soon as the next quarter.

Star Scientific subsidiary Rock Creek Pharmaceuticals announced that golf pro Fred Couples will be the brand ambassador for the company's anti-inflammatory support treatment Anatabloc.
