Hyperdynamics was the market's biggest loser, shedding 40% of its value last week after announcing disappointing oil exploration news for its Guinea site.

Build-A-Bear Workshop had no problem building market bears after delivering an adjusted profit of $0.34 a share, well short of market expectations. The retailer of stuffed playthings points to poorly performing tie-ins to theatrical disappointments Happy Feet Two and Alvin and the Chipmunks: Chipwrecked.

Really? Build-A-Bear didn't know that these two movies would be box office turkeys?

DG was downgraded by several analysts after posting uninspiring quarterly results. DG -- formerly known as DG FastChannel -- runs a network of TV and online advertising. saw weak sequential subscriber growth in its latest quarter. The leading genealogy website operator also posted a spike in subscriber acquisition costs and issued soft guidance for the current quarter.

Vonage failed to connect with investors after missing Wall Street's profit forecast in its latest quarter and warning of near-term weakness on the bottom line as it ramps up its marketing spending to woo new users to its Web-based phone service.
