“The more you spend, the more you receive”, seems to be Jack Ma’s favourite saying, which is indeed verified in the fullest.

The 49 year-old billionaire, founder and executive chairman of Alibaba Group has spent 5 billion dollars in eight big deals since the beginning of the year. However, just on Wednesday, he became richer by 1.5 billion from various investments!

As Forbes mentions, the 5 billion corresponds to a check of about 1 billion per month. Without taking account of small amounts, like 15 million, that Alibaba invested in the American e-commerce and luxury goods company 1stdibs or the 20 million invested in Chinese travel service provider Byecity.com.

Of course, as the magazine states, all these deals, spanning media, education, pharmaceuticals and tech fields, were not funder by Jack Ma’s personal wallet, whose fortune is estimated at 13 billion. However, he is arguably the “brains” behind each of these agreements.

Although he retired from his position as CEO last May, Jack Ma continues to define the company’s strategy. Besides that, he also has a 7.4% stake in the Alibaba Group chinese e-shop giant, whose worth is estimated at 168 billion by Bloomberg analysts. His share will be reduced to 7.1% after the forthcoming IPO of the company on Wall Street in 2014.
