Wall Street Overview

Stocks were falling significantly but off session lows Thursday after the arrest of a high-level Chinese business executive in Canada that threatens to unravel the trade truce between Washington and Beijing.

Meng Wanzhou, the chief financial officer of China's Huawei Technologies Co. and the daughter of the company's founder, was detained in Vancouver on Dec. 1, and faces extradition to the United States amid reported allegations that she assisted the world's second-largest smartphone maker in evading U.S. sanctions on Iran.

News of the arrest, which only came to light late Wednesday, sent global shares lower as investors worried about reprisals from Beijing and the potential collapse of the uneasy truce between Donald Trump and Chinese President Xi Jinping.

"At the request of the U.S. side, the Canadian side arrested a Chinese citizen not violating any American or Canadian law. The Chinese side firmly opposes and strongly protests over such kind of actions which seriously harmed the human rights of the victim," said the Chinese embassy in Canada in a statement. " The Chinese side has lodged stern representations with the U.S. and Canadian side, and urged them to immediately correct the wrongdoing and restore the personal freedom of Ms. Meng Wanzhou. We will closely follow the development of the issue and take all measures to resolutely protect the legitimate rights and interests of Chinese citizens."

The Dow Jones Industrial Average fell 79 points, or 0.32%, to 24,948, the S&P 500 declined 0.15%, and the Nasdaq was gained 0.42%. The Dow and S&P closed the day holding on to slim year-to-date gains. 

While the selling is related to concerns about future trade relations, "we believe the market has over-reacted and is now overpricing these risks," Mark Haefele, chief investment officer for UBS wrote in a note to clients Thursday afternoon.

Chipmakers linked to Huawei were paring losses Thursday and smartphone rivals such as Apple Inc. (AAPL) - Get Report faced the prospect of consumer boycotts or restrictions should authorities in China choose to react.

Advanced Micro Devices Inc.  (AMD) - Get Report , which provides chips for Huawei's MateBook D tablet, and Micron Technology Inc.  (MU) - Get Report   traded mixed Thursday after falling sharply earlier in the session.
