China Tech Stocks Jump as AI Boom Pushes Index to Four-Year High

A blistering rally in Chinese technology shares accelerated on Wednesday as renewed bets on artificial intelligence sent a key gauge to the highest in nearly four years.

The Hang Seng Tech Index, which tracks the largest tech firms listed in Hong Kong, rose 4.2% to close at its highest level since November 2021. Search engine operator Baidu Inc led gains with a 16% jump but multiple tech giants came along for the ride: Shares of Alibaba Group Holding Ltd., Semiconductor Manufacturing International Corp, and JD.com Inc all surged.

The index is now set for its seventh consecutive week of gains, helped by easing tensions between China and the US as well as hopes that tech companies’ big bets on AI will pay off. The gauge has jumped 42% this year, trouncing a benchmark of regional peers.

“China tech leaders are visibly re-accelerating AI spend and product rollouts — models, robotaxis, in-house chips — while also proving they can monetize AI faster than many expected,” said Charu Chanana, chief investment strategist at Saxo Markets. “With valuations lagging the U.S., investors are starting to pay attention again.”
