Diamond in the rough? You better believe it. The nutty company is booting its CEO and CFO, restating past financials, and is likely not going to close on its deal to acquire Pringles.

iRobot pulled the whole "I'm sorry Dave, I'm afraid I can't do that" routine on investors after delivering uninspiring guidance for 2012. The company makes military automatons as well as consumer robotics.

Astex Pharmaceuticals called in sick after an advisory panel -- not the FDA -- voted against recommending the biotech's treatment for acute myeloid leukemia for patients over the age of 65. Fellow Fool Sean Williams sees the drop as a buying opportunity given Astex's meaty cash position and diversified revenue stream.

Chinese dot-com Sohu slipped after warning that earnings for its current quarter would come in at less than half of the $1.15 a share that analysts were projecting.

Solar stocks may have bounced back last week, but Amtech Systems missed the wake-up call. The solar equipment supplier saw its shares slide after posting a quarterly loss and warning of a widening deficit for the current quarter.
