Heckmann was the market's biggest winner, soaring better than 50% after announcing the acquisition of Power Fuels. Companies don't often move higher -- and much less markedly higher -- when they're the ones doing the buying, but this deal enhances Heckmann's position. Power Fuels generated $155 million in EBITDA last year, and has promising operations in the Bakken shale.

Questcor Pharmaceuticals climbed on favorable news concerning Medicaid reimbursements from the government for its multiple sclerosis drug.

RadioShack rallied after the small-box retailer introduced its own brand of no-contract wireless. Even though this is essentially the Cricket pay-as-you-go platform with a RadioShack wrapper, investors were excited to see signs of life at RadioShack.

Alpha Natural Resources was one of the many coal producers moving higher after China announced $156 billion in infrastructure spending to help stimulate its slowing economy.

Finally, shares of Green Mountain Coffee Roasters were brewing hot after Lazard Capital Markets initiated coverage with a bullish rating and a $39 price target. The company behind the Keurig platform also introduced a line of K-Cups that are fortified with antioxidant vitamins.
