Hong Kong’s Hang Seng Index (HSI) surged on Monday, February 23, 2026, climbing over 700 points and breaking through the 27,000 level as investors reacted positively to a U.S. Supreme Court ruling. The benchmark index closed the morning session at 27,019.21, a 2.29% increase, with a turnover of HK$106.45 billion, according to AASTOCKS.com.
The rally was spurred by the U.S. Supreme Court’s decision to overturn former President Trump’s “equal tariffs” policy, which boosted e-commerce stocks on Friday, February 20, 2026. The Hang Seng Index opened higher by 385 points, or 1.5%, and continued to climb throughout the morning session. This decision highlights the market’s sensitivity to international trade policy.
The Hang Seng China Enterprises Index (^HSCE) rose 260 points, or 2.9%, to close at 9,220. Meanwhile, the Hang Seng Tech Index (HSTECH.HK) gained 198 points, or 3.8%, reaching 5,410, as reported by Yahoo Finance. The strong performance across all three indices signals broad-based investor confidence.
According to Hong Kong Economic Journal, technology stocks led the gains, with significant contributions from Alibaba (09988) and Tencent (00700), adding over 100 points to the Hang Seng Index. The surge in these key stocks drove the overall market increase of 650 points.
The positive momentum comes ahead of a planned meeting between Hong Kong and mainland Chinese officials. The market’s reaction suggests investors are anticipating favorable outcomes from these discussions, as noted in Orange News.
Analysts are also pointing to the resumption of “northbound” investment flows as a contributing factor to the market’s strength, according to Hong Kong Wenhui Network, suggesting renewed interest from mainland Chinese investors.
