Independent oil and gas company Petrohawk Energy won't be independent for too much longer. Shares soared on Friday after BHP Billiton (NYSE: BHP) offered to buy the shale gas producer in a $12.1 billion deal that will take out investors at $38.75 a share.

Orbitz Worldwide took off after the travel booking specialist entered into a partnership with Virgin Australia to power stand-alone hotel bookings on the Australian website. This may not seem like meaty news, but it was enough to give Orbitz its heaviest trading volume in over a month.

Gulf Resources bounced back after the Chinese bromine producer reaffirmed its corporate structure. Its chairman and his family also agreed to hold their shares for at least the next three years. This is pretty substantial news, since they own nearly 39% of the company.

Ladenburg Thalmann initiated coverage of ZAGG with a "buy" rating on Wednesday. The analyst is setting a price target of $20 on the maker of protective screens and other accessories for smartphones and tablets.

Clean Energy Fuels moved higher after a timely Chesapeake Energy (NYSE: CHK) investment that will help the company build up its fleet of 150 vehicle-grade natural gas refueling stations. A Bank of America analyst upgrade followed the following day.
