Swisher was flushed by Wall Street after the company's CEO announced that he was leaving on Monday. Swisher also received a Nasdaq notice indicating that the company is not in compliance for its exchange listing.

Big Lots fell -- lots -- after posting a brutal quarterly report. Profit clocked in well short of expectations, and sales also failed to live up to projections as domestic stores suffered a nearly 2% slide in comps. The retailer of discounted clearance and overstocks is apparently not the all-weather investment that many investors thought it would be.

ImmunoCellular Therapeutics slipped after the fledgling biotech's CEO -- Manish Singh, who was also the company's president and a board director -- resigned.

ZAGG took a hit after the maker of protective screen covers and other gadget accessories revealed that its CEO would be stepping down. A margin call forced him to sell a chunk of his company's stock a week earlier.

Best Buy got even cheaper after posting a lousy quarterly report and handing its new CEO an outrageous pay package.
