Why the divorces of China’s A-share firm owners provoke market nerves

China’s A-share market has seen another high-profile divorce case result in a massive asset split, involving the transfer of 6 billion yuan (US$886 million) – the highest this year – and raising concerns over corporate governance stability and share price fluctuations.Although the scope of the divorce settlement is not at all comparable to that of Jeff Bezos or Bill Gates, it has made tens of thousands of retail investors worry about their portfolio holdings and paper wealth.Maxone Semiconductor Suzhou Co, the first domestic probe card maker listed on Shanghai’s Sci-Tech Innovation Board, said in an exchange filing last week that its president, Zhou Ming, 53, had completed all the legal procedures and divided his shareholdings following his divorce.
