There's never a shortage of losers in the stock market.

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


June 15 Weekly Loss My Watchlist
EnergySolutions (NYSE: ES) $1.69 (53%) Add
MicroVision (Nasdaq: MVIS) $2.27 (22%) Add
Centene (NYSE: CNC) $28.20 (21%) Add
Lattice Semiconductor (Nasdaq: LSCC) $3.76 (20%) Add
MeetMe (AMEX: MEET) $2.23 (17%) Add

EnergySolutions was last week's biggest loser, shedding more than half of its value after the nuclear decontamination and decommissioning company revised its annual outlook lower and announced an executive shakeup.

MicroVision slipped after completing a dilutive secondary offering. The move may have helped MicroVision gain listing compliance, but the market obviously wasn't impressed with the terms of the deal.

Centene called in sick after offering up an uninspiring outlook. The managed-care provider now sees an annual profit per share between $1.45 and $1.65, well off its prior view calling for net income to clock in as high as $2.84 a share.

Lattice Semiconductor also wasn't telling investors what they wanted to hear. Lattice is slashing its revenue guidance for the current quarter. Adding insult to injury, it's also lowering its gross margin forecast.

There wasn't any company-specific news behind MeetMe's 17% slide, but investors clearly didn't warm up to the social discovery's rebranding efforts a week earlier. MeetMe was known as QuePasa until earlier this month.
