As Amazon's 'Alexa' Shines At CES, Jeff Bezos Gets $1.3 Billion Richer In A Day

The fortune of Jeff Bezos, founder and CEO of Amazon, rose by $3.8 billion in the first week of 2017. The new year has just begun, and Jeff Bezos' net worth is already up almost $4 billion. Coming off a difficult three-month stretch in which Amazon lost more than 10% of its value, the company's stock is once again surging. Between Monday morning and Friday afternoon of this week, Amazon's share price rose by nearly 4%, closing at $795.99 per share at the end of normal trading at 4 P.M. EST Friday. For Bezos, who owns more than 80 million shares and whose personal fortune is almost entirely tied to the business, that increase has led to big personal gains.
