Chinese tech billionaire cashes in by swapping New York for Shanghai
Why be content with almost $2bn when your net worth can be multiples more simply by moving your company from one stock exchange to another?
Zhou Hongyi did just that, relocating his online security firm to China and merging it into a shell company, which soared as much as 550pc since he announced the plan in November.
Qihoo 360 Technology Co delisted from the New York Stock Exchange in July 2016 and began trading on Wednesday in Shanghai as 360 Security Technology Inc. The move boosted Zhou's net worth to $14.1bn (€11.5bn), making him China's 11th-richest person, according to the Bloomberg Billionaires Index.
Zhou, 47, told reporters in November that aligning himself with China's national interest was among the reasons he moved the listing to his homeland, where the Communist Party has been tightening the country's 'cybersecurity sovereignty'.
The first day back has been rocky. The shares swung between gains and losses in the morning trading on Wednesday - opening 3.8pc higher before declining as much as 10pc. The stock fell 6.4pc to 59.15 yuan as of 10.49am in Shanghai.
Still, China's richer tech valuations may have been a draw, said Sun Mengqi, an analyst at BOCOM International Holdings Co, who added: "There could be a substantial valuation gap between the US and China."
Zhou owns a 23pc stake in 360 Security - directly and through holding companies Tianjin Qixin Zhicheng Technology and Tianjin Zhongxin Investment - according to an acquisition proposal last month.
Yue Jing, a company spokeswoman, declined to comment on Zhou's net worth.
The firm posted 2016 revenue of 9.9 billion yuan (€1.3bn), up from 9.4 billion yuan a year earlier. Most of its sales come from online ads, many which are pushed to users of its antivirus products.
Zhou isn't the first tech mogul to take the back door to China.
Billionaire Jason Jiang's Focus Media went private in a $3.7bn buyout in 2013 after coming under pressure from short-seller Carson Block, relisting two years later in Shenzhen.
The company's market value has swelled to $29bn since then.
Zhou did a stint as the head of Yahoo China in the 2000s after selling a search engine startup to the US firm and, in 2006, co-founded Qihoo 360 with fellow billionaire Qi Xiangdong.
