Hang Seng Jumps 3.7%: Hong Kong's Best Day in 21 Months as Money Flees AI Chips

The Hang Seng Index jumped 3.67% on Thursday, November 5, 2026, closing at 24,796.98 points — its best single day in about 21 months — as investors rotated out of AI hardware stocks and into discounted Chinese internet giants. The Hang Seng Tech Index surged 5.55% to 4,154.29, its largest gain since February 2025, while Alibaba, Tencent, Xiaomi and NetEase all rose 7% or more.

What happened in Hong Kong?

Hong Kong stocks rallied on heavy volume on November 5. The Hang Seng added 877.48 points, rising as much as 952 points, or 3.98%, during the session before closing up 3.67%. The Hang Seng China Enterprises Index gained 3.87% to 8,369.08, and main-board turnover reached HK$356.6 billion, according to market reports.

The gains were broad among large internet platforms. NetEase rose more than 9%, Alibaba gained about 8.5%, Xiaomi climbed nearly 9%, Tencent rose more than 7%, and Meituan and JD.com each rose nearly 7%. Baidu added more than 5% and Kuaishou advanced about 5%. It was the Hang Seng Tech Index's fifth consecutive day of gains.

Why is this blowing up now?

The rally was the other side of Asia's AI selloff. On the same day, South Korea's KOSPI plunged as Samsung Electronics and SK hynix fell sharply, and chip stocks across Japan and Taiwan sold off. Investors feared that the Democrats' sweep of the US midterm elections could bring tighter regulation of AI data centres, delaying expansion and curbing demand for semiconductors and hardware.

Hong Kong was positioned differently. Its biggest stocks are internet platforms tied to e-commerce, social media, gaming, payments and local services — businesses less exposed to AI hardware spending. After languishing for much of the year, those stocks looked cheap. Reports citing Bloomberg said the Hang Seng Tech Index's forward price-to-earnings ratio hit 13 last month, the lowest since 2024, drawing buyers looking for value and consumer exposure instead of crowded AI trades.

Overnight support helped too. The Nasdaq Golden Dragon China Index had closed up 3.49%, with Chinese concept stocks listed in the US generally gaining 3% to 5%, setting up Hong Kong's open.

What happened next?

The move did not hold untouched. On Friday, November 6, Hong Kong gave back some ground as the wider Asian selloff spread, with the Hang Seng slipping about 1.06% in reports of Friday's trade. That pullback underlines the risk in a one-day rotation: Hong Kong benefited because it was less exposed to AI hardware, not because the global selloff had ended.

Whether the rally persists depends on whether the rotation out of AI hardware continues, whether valuations stay attractive enough to keep drawing buyers, and how US policy after the midterms affects data-centre and chip demand. For now, Thursday's session is a clear snapshot of a market changing its mind in real time — selling the hardware behind AI and buying the discounted platforms that sell to consumers.
