News of 'Ma' arrest in China makes Alibaba investors dump $27 billion

Alibaba shares fell as much as 9 per cent on Tuesday after a state media report that Chinese authorities had taken action against an individual surnamed Ma, but recouped losses after the report was revised to make clear it was not the company's founder.

State broadcaster CCTV first reported that authorities in the city of Hangzhou, Alibaba's headquarters, had taken action against an individual surnamed Ma, whose name consisted of two Chinese characters, suspected of using the internet to engage in activities endangering national security.

Investors quickly dumped their shares, causing the stock to crash by as much as 9.4 per cent, erasing about $27 billion in share value.

The broadcaster later revised the article to make clear that the individual in question had a three-character name, indicating that it was not billionaire Alibaba founder Jack Ma.

A spokesperson for Alibaba did not immediately respond to a Reuters request for comment on the media report.

Alibaba stock dropped as much as 9.4% in early trading in Hong Kong in a firmer broader market. It later pared most of its losses and was trading down 1.1% by 0310 GMT.

"Talk that a guy with the surname Ma in Hangzhou helped out an investigation triggered the panic, but as clarification came up... (it helped) calm down the market," said Steven Leung, a sales director at brokerage UOB Kay Hian.

Shares of Alibaba and other Chinese internet companies have been under pressure in the last couple of years amid an unprecedented regulatory crackdown on the sector for violations of antimonopoly, data privacy, and other rules.

Authorities cracked down on Ma's business empire after his speech in Shanghai in October 2020.

Regulators suspended the $37 billion listing of his fintech firm Ant Group two days before its planned debut on Nov. 5, 2020, ordered that Ant be restructured and launched antitrust investigations into Ma's businesses, eventually leading to a record $2.75 billion fine for Alibaba in April 2021.

Ma himself has been keep a low public profile since the crackdown began.
