The Hang Seng Index declined 2 percent to take its weekly drop to 2.5 percent, the biggest loss since mid-December. Tencent Holdings Ltd. tumbled the most since February 2016 as investors took profit in some top performers. The HSI Volatility Index, which measures expected price swings on the Hong Kong benchmark, climbed 16 percent for its biggest weekly advance since January 2016. The Hang Seng China Enterprises Index and Shanghai Composite Index both also fell the most this year on Friday, according to Bloomberg.
“All the investors are screaming, ‘where’s the door?”’ said Andrew Clarke, director of trading at Mirabaud Asia Ltd. in Hong Kong. “Hong Kong has been a market where it’s all in or all out -- retail clients are taking big profits.”
Tencent, which soared 74 percent this year through Wednesday, fell 4.9 percent after a selloff in technology stocks in the U.S. and as it emerged the company is being investigated for cyber-security law violations. Other outperformers this year also hit the brakes, with Geely Automobile Holdings Ltd. and AAC Technologies Holdings Inc. falling at least 3.8 percent. Hong Kong Exchanges & Clearing Ltd. continued its slide from Thursday, when China Merchants Securities Co. was among those to downgrade the company to sell.
Global equity markets were down after U.S. President Donald Trump issued another warning to North Korea, promising a response to any strike against America or its allies. U.S. equities sold off the most since May on Thursday, sparking an unprecedented rush for protection in the options market.
Mainland investors also took profit in Hong Kong stocks through trading links. They offloaded net 1.2 billion yuan ($180 million) of shares through the Shanghai and Shenzhen links, the most since Dec. 8, according to data compiled by Bloomberg. It was the first net selling through Shenzhen since the launch of the program early December.
