Bezos’ Amazon is having a record year: its stock has rung up a 60% gain since January 1. The stock surged 13% on just one day, October 26, when the e-commerce giant announced third-quarter earnings that far exceeded expectations. That was also the day that Bezos, who gained $7 billion in hours, became the world’s richest person, a title he’s held ever since.

The world’s richest real estate tycoon, this Chinese billionaire’s fortune nearly quadrupled since the start of the year. The jump is entirely tied to a 400% rise in the stock price of his Evergrande Group. Much of that bump came after the company announced strong financial results in July for the first half of the 2017 fiscal year, as revenues increased by 115% and net profits climbed 224%. The real estate group has commercial and residential properties in more than 200 cities across China. He also controls Evergrande Health, which is working with Brigham and Women’s Hospital of Boston to improve healthcare in China.
