Alimera Sciences was last week's biggest dog, shedding nearly three-quarters of its value after the FDA rejected the company's flagship drug candidate, Iluvien. Upstart biotechs with thin pipelines are obviously at the mercy of regulatory approvals during the drawn-out clinical trial process.

Primo Water hosed down its near-term outlook, and its guidance for the current quarter suggests a sequential decline. The bottled-water distributor also talked down the holiday prospects of its Flavorstation home beverage system.

A few analysts downgraded Rovi after the home theater tech guru posted uninspiring quarterly results. Rovi also issued 2012 guidance that's well short of the top-line growth that Wall street was forecasting.

Green Mountain shares were grounded after the Keurig and K-Cup company posted weaker-than-expected quarterly results.

ATP is facing mounting skepticism on its ability to meet rising bond yields. Despite its CFO's attempt to calm investors by pointing out that it has no intention of skipping any interest payments, one analyst downgraded the company's bonds on bankruptcy concerns.

It was a rough week for these five stocks. Let's see if they bounce back.
