…As strong earnings report caused Facebook shares to surge Thursday

Even if you’re having a good day, it’s still probably not going as well as Mark Zuckerberg’s. The Facebook founder made a cool $6 billion in the past day after a strong earnings report Wednesday caused the value of his Facebook shares to soar.

Zuckerberg’s net worth climbed to $47.6 billion as of 4 p.m. EST, when Facebook stock price closed at $109.11. That makes him the sixth-richest person in the world behind Mexican telecommunications tycoon Carlos Slim Helu (who’s worth $49.5 billion, according to Forbes).

Facebook shares have risen by more than 15% Thursday after its earnings report exceeded analyst expectations, CNBC reported. The social media giant—which has a market value of almost $310 billion—reported $5.8 billion in revenue in the fourth quarter of 2015. Its share prices have spiked more than 43% in the past year.
