Not bad for a day's work!
Shares in Facebook, the world's most visible social media network soared 29.6% Thursday, closing at a one-year high of $34.36.
The share price jump means the network's founder and CEO Mark Zuckerberg's personal fortune increased by $3.8bn in the space of a single day.
In March, FORBES estimated that Zuckerberg, 29, of Palo Alto, California, was worth $13.3bn on their World's Billionaire list. They now see him valued at $16.1bn.
Facebook's second quarter earnings - which surpassed expectations - were aided by the increasing demand for mobile advertising, something lacking this time last year. Between April and June, Facebook received $655.6m from mobile advertising in what is a 41% share of their total advertising revenue ($1.6bn).
In a statement quoted by BBC, Zuckerberg said: 'The work we've done to make mobile the best Facebook experience is showing good results and provides us with a solid foundation for the future.
'This quarter marks the end of our first year as a public company and I think we've created a good foundation for the future.'
The total number of Facebook users on mobile is currently 819m.
