10 of Wall Street's Biggest Losers This Week

It's been a volatile week for investors, but certain stocks suffered far more than others. Here's a rundown of some of the biggest losers -- where they were on Monday and what they cost as of Friday's closing bell.

The Details Behind the Dive

PacSun wiped out after revealing a gloomy outlook for the current quarter. The teen retailer sees same-store sales falling in the mid- to high single-digit range for its fiscal third quarter. PacSun also expects to post a much larger deficit for the period than what the pros had been targeting. It's a shock to shareholders, since comps had managed to tick slightly higher during the second quarter.

"We had expected this positive momentum to continue, yet we are now more cautious in our near term outlook," explains CEO Gary Schoenfeld.

USA Truck came to a screeching halt at the weigh station. The dry van truckload carrier now expects to post a loss for the current quarter, reversing a year ago profit. USA Truck is blaming the deficit on decreased efficiency on the heels of implementing a new enterprise software suite. It sees this as a temporary setback, but investors will just keep on truckin' elsewhere.

AIB remains the poster child of Ireland's financial crisis. The banking giant feels that it can shave a good chunk of overhead by consolidating many of its employees from Dublin to its large head office complex in Ballsbridge.

OmniVision Technologies came down with a bad case of redeye today after issuing problematic guidance for the current quarter. The camera sensor maker now sees revenue slipping sequentially to between $255 million and $275 million. It's targeting earnings to check in between $0.52 a share and $0.64 a share. Analysts were banking on a profit of $0.80 a share on $305 million in revenue. In short, it's not a pretty picture.

Digital media solutions provider RealNetworks tanked on no material news. Research in Motion (RIMM) launched a digital music service similar to Rhapsody, but if investors bailed on RealNetworks because of that they must've missed the memo. RealNetworks unloaded its Rhapsody America music subscription last year.

Adolor moved lower, but it's not as if the Pennsylvania-based biotech did anything wrong. Investors are simply likely taking profits after positive clinical trials were announced earlier this month on a treatment for chronic non-cancer pain for patients with opioid-induced constipation.

Inphi slipped after the chip designer announced that delays on new memory products and a slowdown in orders from some customers would eat into its near-term outlook.

United Therapeutics called in sick after disappointing results on an oral treatment for lung disease. The news came as a bit of a surprise since treprostinil is already approved as an injectable, inhalable, and intravenously administered therapy.

One week's losers rarely repeat the following week, but VanceInfo apparently heard the jeers and decided to come out for an encore performance. The Chinese IT service specialist slipped last week after its CEO felt that the near-term outlook for his industry lacked "clarity." The uncertainty is still sinking in for investors.

RealPage investors suffered paper cuts after the property management software provider made an unpopular acquisition. RealPage is buying Multifamily Technology Solutions in a deal valued at $74.4 million net of cash that it's acquiring. Multifamily is the parent of rental listing website MyNewPlace. The purchase makes tactical sense, and the stock did make back most of its initial hit on the news.

Cheer Up

If you own one or more of these stocks, my condolences. Some of these companies should bounce back. If you were looking to buy into any of these stocks, the fundamentals behind the sharp declines will likely temper your enthusiasm -- but congratulations on the opportunity to get in at a more attractive price.

Hold your head up either way. The new trading week awaits at the other end of the weekend.
