China Digital was worth watching after the Chinese set-top box specialist announced a special one-time dividend of $2.30 a share. That's a pretty substantial declaration for a stock that began the week trading for less than $3.

Facebook moved higher after bucking the conventional wisdom that believes a stock will move lower as lockup expirations expire on the shares held by pre-IPO investors. Facebook also announced on Thursday that several prolific retailers would be joining its Facebook Gifts platform.

Sarepta Therapeutics got a bump higher after a JMP Securities analyst issued a cautionary note on a rival that's also working on a Duchenne muscular dystrophy drug. She doesn't see approval of that company's treatment until 2014 at the earliest. Sarepta's own candidate has been holding up well through clinical trials.

Clean Energy moved higher after agreeing to purchase a pair of plants that will create an initial capacity of 250,000 gallons a day of liquefied natural gas.

Research In Motion moved higher after finally announcing a firm date to introduce BlackBerry 10. Skeptics will argue that it's too late to save RIM, but at least now it has a shot. The event is slated for Jan. 30.
