This guy is on track to have a $5bn day

Wow

Yep, an increase in his net worth of $5bn in a day - just for getting up.

Friday has been a good day for Jeff Bezos .

Amazon 's CEO, who owned 83,933,463 company shares as of Feb. 19, is on track to having a $5 billion day. The company's stock surged more than $59, or nearly 15 percent, to about $449 a share, according to FactSet. ( Tweet This ).

To put this into perspective, Bezos' one-day paper gain would be larger than the individual market caps of 17 S&P 500 companies.

The company's stock surge came one day after it reported that Amazon Web Services, which includes its cloud business, generated $1.57 billion in revenue during the first quarter, leading Wall Street to nudge off its earnings per share miss.

Bezos, however, was not the only one having a good day. Steve Ballmer , Microsoft's former chief executive and current owner of the Los Angeles Clippers, is on track to making a little over $1 billion Friday, which amounts to about half of what he paid for the NBA franchise.

Microsoft shares rose nearly 8 percent Friday to about $46 a share in late-morning trading, as Wall Street cheered the company's latest quarterly results.

Ballmer owned 333,255,000 Microsoft shares as of Feb. 19, according to FactSet, which equals to approximately $1.07 billion.
