CNN Money reports:
Amazon stock jumped 13.5% on Friday after the company turned in another incredible earnings report — more than a quarter-billion dollars in profit in three months. CEO Jeff Bezos owned nearly 80 million shares in Amazon as of August, according to the most recent available data from FactSet. He made more than $10 billion from the one-day stock surge and is now worth well over $90 billion.
At the end of trading on Thursday, Bill Gates occupied the top spot in the Bloomberg Billionaires Index, with a net worth of $88 billion. Bezos had $83.5 billion, and his big day on Friday was more than enough to close the gap. But Gates also got a boost as Microsoft stock rose 7%. Gates owned 103 million shares as of September, according to FactSet. Microsoft stock climbed about $6 a share, so Gates added almost $600 million to his personal wealth.
