Chinese probiotics maker China-Biotics took a hit after a scathing report. The bearish piece -- penned by a guest contributor -- detailed an unimpressive tour of the company's facilities relative to its productivity claims. Raising doubts about a smallish Chinese company has been a popular attack strategy by shorts, but now it's time for China-Biotics to respond.

Talbots took a hit after the frumpy retailer offered up a disappointing quarterly report. Some analysts have had enough. Oppenheimer slashed its price target on the apparel chain from $11 to $4. The shares did make up some of its lost ground after a Bloomberg article pitched Talbots as a buyout candidate, but the stock still closed 36% lower on the week.

Neoprobe took a hit on concerns that Lymphoseek -- part of a test to detect the spread of certain tumors -- won't cut it with the Food and Drug Administration. The company fired back on Wednesday, accusing a petitioned attempt to block Lymphoseek as the handiwork of a short-seller.

A123 lost its spark after Pacific Crest Securities downgraded the maker of lithium-ion batteries that are popular with electric cars. The analyst argues that A123's lack of profitability will likely force it into a secondary offering by early 2013.

Finally, we have Hovnanian crumbling like moldy drywall. The homebuilder posted a wider than expected quarterly loss on a 20% dip in revenue. Shrinking gross margins, higher cancellations, and a dip in its order backlog didn't give investors any reasons to stick around.

It was a rough week for these five stocks. Let's see which ones bounce back this week.
