Last week wasn't one for the bears.

There weren't too many losers with the Dow, S&P 500, and Nasdaq soaring 3.1!%, 2.7%, and 3.8%, respectively. However, there are always tumblers.

Let's take a closer look at five of this past week's biggest sinkers.

Shares of Chinese kitchen gadgetry maker Deer Consumer Products were minced after a financial blog hinted at fraud allegations through a questionable land use rights purchase. Is Deer caught in the headlights? Bearish bloggers can sting when their zingers raise eyebrows. Just ask Ebix (Nasdaq: EBIX). The insurance software provider slipped 16% last week after its practices came under fire.

XOMA came up short in a clinical trial to get its XOMA 052 drug approved as a treatment for diabetes. It's not the end for the drug. XOMA 052 still has hope in treating everything from arthritis to gout, but failing to top the placebo in effectiveness when it comes to tackling diabetes is a major setback.

Gulf Resources slipped after the Chinese maker of bromine, crude salt, and specialty chemical products had to retract a misstatement it made a week earlier about the projected capacity of a leased facility. It doesn't seem like much of revision, but investors get nervous when facts are rearranged.

Brightpoint took its lumps after a Citigroup analyst downgrade. There are fears that Brightpoint's business with T-Mobile will dry up if AT&T (NYSE: T) succeeds in its plan to acquire the rival carrier.

Shares of BroadSoft got dinged up as the hot IPO approached the end of its lock-up period. There's no sign that insiders will begin bailing, but it's going to be awfully tempting given the mobile multimedia specialist's monstrous run since going public last year.

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