Tencent CEO Pony Ma appears to have sold off 23 million shares of the company’s stock through four transactions that put the value of stock sold at above US$400 million, Tech In Asia reported, citing Hong Kong stock exchange data. According to Sina Tech, the sale lowered Ma’s ownership of the company from 9.62% to 9.37%. The news comes shortly after Bloomberg reported that Tencent’s merger and acquisitions chief, Richard Peng Zhijian, is leaving the company after having helped drive the company’s participation in at least 90 deals worth around US$19 billion during his seven-year tenure there.
