What's better than momentum? Mo' momentum.

Last week wasn't particularly kind for equity investors. The Dow suffered a 2% decline, and the tech-heavy Nasdaq Composite fared even worse with a nearly 3% slide. There were thankfully more than a few stocks bucking the trend.

Let's take a closer look at five of this past week's biggest scorchers.

Jamer River Coal was the biggest gainer among Nasdaq-listed companies. It was a good week for coal stocks, boosted by encouraging news about China's coal-hungry steel mills and an uptick in natural gas prices. James River Coal was the biggest beneficiary on a percentage basis, though Arch Coal also came through with a double-digit percentage pop.

VIVUS soared after its weight-loss pill Qsymia -- the first new obesity drug on the market in 13 years -- entered into a distribution deal with Express Scripts (NASDAQ:ESRX).

First Solar was a shooting star after an analyst at Cantor Fitzgerald waxed positively on the shares. The analyst feels that recently announced U.S. anti-dumping tariffs will increase domestic demand for First Solar's panels.

MeetMe moved higher after completing the final step in its strategy to combine its assets under a single brand. The transition of Quepasa.com users to the MeetMe platform is now finished.
