Today is January 2nd, the A-shares market is closed, but the Hong Kong and U.S. stock markets are open as usual.
1. A significant rise on the first trading day of 2026

Real-time market data shows that the three major indices of the Hong Kong stock market opened high and rose collectively today. The Hang Seng Tech Index performed impressively, with intraday gains expanding to over 3%, leading the market; the Hang Seng Index also rose by 2%.

The leading sectors are chip semiconductors, AI artificial intelligence, and internet technology stocks. BAT stocks rose broadly, with Baidu leading the gains; Hua Hong Semiconductor surged over 11%; the robotics sector, including SMC, also rose by 5%.
2. Why is there a significant rise today?
The significant rise in related indices today is not driven by a single factor, but rather a resonance effect generated by the 'super new stock listings' and 'major macroeconomic benefits':
1. 'First GPU stock in Hong Kong' listing surges
The absolute market focus today is the newly listed Biren Technology.
As the 'first GPU stock in Hong Kong', Biren Technology was heavily traded by investors on its debut day. It opened with an 82% surge, with intraday gains exceeding 110%, and its market cap approached HK$100 billion. Later, it declined slightly but remains up 86%, with a market cap exceeding HK$80 billion.
The 'doubling on the first day' profit effect has greatly boosted market sentiment toward hard tech, semiconductors, and AI sectors, directly driving the valuation reshaping of the entire tech sector.
2. Major macro利好: Geopolitical restrictions temporarily 'unlocked'
The strong rally in Chinese semiconductor stocks, such as SMIC, was further supported by a major geopolitical development overnight and this morning.
After Samsung and SK Hynix, the U.S. government has formally approved TSMC's export of chip manufacturing equipment to its factory in mainland China (Nanjing) and granted the license for 2026.
This news significantly alleviates market concerns about semiconductor supply chain disruptions in 2026. The reduction in uncertainty directly benefits domestic wafer foundries like Hua Hong Semiconductor, making the semiconductor sector the main driver for today's long positions.
3. Key stock benefits: Hua Hong acquisition, Baidu spin-off
Hua Hong Semiconductor rose over 11% today. The company issued multiple announcements stating it plans to acquire 97.4988% of Hualil Micro from four transaction parties, including Hua Hong Group, through issuing shares. The transaction value amounts to RMB 8.268 billion.
Through this integration, Hua Hong will directly incorporate Hualil Micro's 12-inch wafer fabrication lines and mature process platforms, enabling continuous growth in production capacity.
Weighted stock Baidu Group surged over 8% during the day, contributing significantly to index gains.
Baidu Group announced early today on the Hong Kong Stock Exchange that its non-wholly owned subsidiary, Kunlun芯, which focuses on AI chip business, has formally applied confidentially for listing and trading of its shares on the main board of the Hong Kong Exchange.
Against the backdrop of Biren Technology's hot listing, the market rapidly revalued Baidu's chip business, creating a 'shadow stock' effect.
4. January effect and tax arrangements
Additionally, the common 'January effect'—where January is often one of the best-performing months of the year for stocks, especially small-cap stocks—exists in the market. This is due to tax considerations: overseas investors sell underperforming stocks at year-end to lock in losses and avoid capital gains tax. After January 1st, investors stop selling and replenish their portfolios, thus driving stock market rallies.
Moreover, investors—including fund managers—are re-planning their investment strategies for the coming year and adjusting portfolios accordingly, pushing up the stock market. High-income investors, who heavily rely on year-end bonuses, have ample cash available for new investments at the start of the year.
III. Impact on A-shares
The Hong Kong Hang Seng Tech Index serves as a leading indicator for China's ChiNext Index and Sci-Tech 50 Index. A strong performance in Hong Kong signals a significant improvement in foreign investor risk appetite, and we expect A-shares tech indexes to open sharply higher on Monday, likely showing a 'strong tech, stable weight' offensive pattern.
1. Semiconductors
The '2026 sanctions anxiety' that has been pressuring China's A-share semiconductor sector has been alleviated due to the approval of TSMC, directly restoring the valuation center of A-share semiconductor stocks.
2. Domestic computing power/GPU sector
The two core drivers in Hong Kong (Biren's listing and easing of geopolitical tensions) will find precise counterparts in the A-share market, and capital will quickly seek 'matching' and 'companion' sectors in A-shares.
3. Space satellites
Today's top performers in Hong Kong's market were commercial aerospace concepts: Asia Satellite surged 28.78% to HK$3.58; Aerospace Holdings rose 18.33% to HK$0.71; Goldwind Science & Technology climbed 12.08% to HK$15.03. This will drive the A-share space technology sector.
4. AI applications and large models
Baidu's H-share surge will also stimulate activity in A-share media, gaming, and AI application sectors.
5. Dividend stocks draining liquidity
A surge in tech stocks may draw capital away from dividend and low-volatility (banking, utilities) sectors. If your portfolio is defensively oriented, you might face a situation next week where the index rises but you don't make money.
