Infinity Pharmaceuticals was the market's biggest loser, shedding 40% of its value after revealing disappointing clinical trial results for its advanced pancreatic cancer treatment. Small biotechs can post big gains when a promising drug bears fruit, but limited pipelines can backfire when things go wrong.

Inergy ran out of energy on fears that it may have to slash its dividend. The propane distributor hit a fresh 52-week low after revealing that cash flows last year were only good enough to cover 68% of its distributions as warm weather ate into propane demand.

Carbo Ceramics stumbled after posting quarterly revenue and earnings that were well below what analysts had been targeting.

Momenta Pharmaceuticals took a hit after a federal appeals court decided to stay an injunction that would have banned a rival from selling a competing generic blood thinner in the United States.

Monster Worldwide had a monster of an announcement, revealing that it will have to let go 400 of its employees -- or 7% of its workforce -- after a disappointing quarter. There may be a punch line waiting in a tidbit on an online recruiter going for layoffs of its own, but pink slips aren't funny.
