Facebook Inc (NASDAQ:FB) gained close to 30% today after the company’s earnings report, delivered on Wednesday after the market closed, beat analyst expectations by a wide margin. The estimated earnings from the company for the June quarter was 12 cents, and the company managed to put up 19 cents, blowing the market for the company’s shares wide open and resulting in unusual one day increases for a widely followed company.

The impetus behind the rise, other than the big beat, was the fact that Facebook Inc (NASDAQ:FB) showed it was a mobile company, and that the desktop business it built itself on was one the company could do well without. Facebook showed that the numbers of users using the service on mobile devices increased by more than 50% year-on-year, while mobile advertising made up around 41% of its advertising revenue in the quarter.

ONEOK, Inc. (NYSE:OKE) shares gained more than 25% on today’s market after the company revealed it was planning to spin off its natural gas distribution business. The new company, which is to be called ONE Gas, will, if the process goes as planned, go public in the first quarter of next year.

ONEOK Inc. (NYSE:OKE) revealed that shareholders will retain their current shares and receive shares in the new gas distribution company. The hike in the price of the company’s shares today was the result of the new deal, as well as analyst reports that raised outlook on the announcement.

Tripadvisor Inc (NASDAQ:TRIP) shares gained more than 16% today after the company revealed an earnings report this morning that beat analyst expectations. The hotel-reviewing site showed a revenue increase of 26% year-on-year with a massive increase in revenue in this morning’s earnings report.
 
Including today’s gains, shares in Tripadvisor Inc (NASDAQ:TRIP) have risen by almost 70% so far in 2013. The company is more successful than analysts had ever imagined at the start of 2013.

Sequenom, Inc (NASDAQ:SQNM) demonstrated that it wasn’t all good news on the Nasdaq today. The DNA analysis company disappointed on the earnings it delivered before the market opened this morning.
