Mainland technology shares rose following a roller-coaster ride on Tuesday, helping lift key benchmark indexes as semiconductor stocks rebounded sharply from earlier losses.

In Hong Kong, the benchmark Hang Seng Index ended 10 points lower at 25,132 on turnover of HK$289.94 billion.

The tech index was 62 points, or 1.3 percent, higher at 4,814 while the China Enterprises Index fell 21 points, or 0.3 percent, to 8,360.

Up north, the benchmark Shanghai Composite Index closed up 68 points, or 1.79 percent, at 3,864.

The Shenzhen Component Index surged 654 points, or 4.81 percent, higher to 14,264 while the ChiNext powered up by 242 points, or 7.05 percent, to 3,685.

The tech-focused Star50 index leapt 10.8 percent, after falling more than three percent in early deals, booking the biggest daily jump since October 18, 2024.

The wild swing came after the index logged a more than 30-percent gain over the past three months, tracking its regional peers.

Semiconductor shares were the best-performing sector, with the CSI 300 sub-index surging 12.2 percent.

"We believe ⁠the tech sector and AI trades will remain the main ⁠investment themes in the second ⁠half of 2026, despite crowded tech trades unwinding somewhat," said Lei Meng, China equity strategist at UBS Securities.

The sector was expected ⁠to remain robust on the back of earnings growth due to rapid AI advances globally, and China's strong policy support, Meng said, a day after China's securities regulator chief chaired a meeting with investors and vowed to make all efforts to maintain stable market operations following a rout over the past two weeks that roiled the stock market.

In Tokyo, the Nikkei jumped 2,091 points, or 3.26 percent, to close at 66,232 as markets reopened after a holiday and investors seized on bargains following the gauge's steepest selloff in more than a year of 6.4 percent last week. The broader Topix climbed 95 points, or 2.44 percent, to 4,014.

In Seoul, the Kospi rebounded to end 231 points, or 3.56 percent, higher at 6,747 as a brutal selloff triggered by the unwinding of leveraged bets began to ease, allowing investors to refocus ⁠on the underlying strengths of a market at the heart of the global artificial intelligence trade.
