A $33 Billion Hit Shows China's Newest Stock Worry

Just as China’s beleaguered tech stocks look to have put the worst of their regulatory blues behind them, a new threat is emerging as firms ramp up a battle for business at home.

A report this week that JD.com Inc. is launching a subsidy campaign to fight back against the advances of rival PDD Holdings Inc. sent fresh shivers through the sector, slamming shares in both firms and their larger e-commerce rival Alibaba Group Holding Ltd. Together, the three companies lost $33 billion of market value in US trading on Tuesday, according to data compiled by Bloomberg.

Moves by Beijing to wind back its bruising crackdown on the tech sector were well received by investors in the back half of last year, but that optimism is now starting to ebb. Instead, markets are fretting about costly price wars and fresh rounds of cash burn as firms that are struggling to expand internationally intensify rivalries at home.

“With overseas opportunities for Chinese Internet companies drying up, it will be harder for them to do business and make acquisitions overseas going forward,” said Robert Lea, an analyst at Bloomberg Intelligence. “Hence they will be more focused on the domestic market for growth, resulting in rising competition, including on pricing.”
