On September 23, 2026, the Hong Kong stock market presents unique sector rotation characteristics against the backdrop of global economic restructuring and accelerated technological innovation. As the global economy gradually recovers and combined with the wave of technological innovation, the Hong Kong market is ushering in a new round of structural opportunities. This article will provide an in-depth analysis of the performance logic, investment value, and future trends of current hot sectors in Hong Kong, offering valuable references for investors.
I. Overview of the Hong Kong Market in September
As of September 23, 2026, the Hang Seng Index is fluctuating around the 24,000-point mark, with the overall market showing an upward trend with fluctuations. In terms of trading volume, the average daily trading volume in the Hong Kong market has maintained above 80 billion Hong Kong dollars, indicating active market trading. Notably, southbound capital continues to flow in, with a cumulative net inflow of over 30 billion Hong Kong dollars since September, showing international investors' confidence in the Hong Kong market.
From a valuation perspective, the overall valuation of the Hong Kong market is still at a relatively low historical level, especially compared with other major global markets, Hong Kong has significant valuation advantages. The Hang Seng Index's P/E ratio is about 11 times, lower than the historical average, providing a better safety margin for long-term investors.
II. New Energy Sector: Dual Drivers of Policy Support and Industrial Upgrading
Among all hot sectors, the new energy sector has performed most impressively. Since September, the new energy index has risen by more than 8%, outperforming the market. This performance is mainly benefited from the dual benefits of accelerated global carbon neutrality process and policy support for China's new energy industry.
In terms of sub-sectors, the new energy vehicle industry chain performance is particularly prominent. On one hand, the penetration rate of global new energy vehicles continues to increase, expected to reach more than 25% in 2026; on the other hand, China's new energy vehicle industry chain occupies a leading position globally, especially in core links such as batteries, motors, and electric control systems, which have obvious advantages.
Specifically, the lithium battery materials sector in the upstream of new energy vehicles shows strong performance. With the rapid growth of global new energy vehicle sales, the demand for key raw materials such as lithium, cobalt, and nickel continues to be strong. At the same time, battery technology innovation continues to advance, and new battery technologies such as solid-state batteries and sodium-ion batteries are gradually commercialized, bringing new growth points to the industry chain.
The midstream battery manufacturing sector also performs well. Leading battery manufacturers continue to increase their market share through technological advantages and scale effects. At the same time, the battery recycling system is gradually improving, bringing new business models to the industry.
In the downstream new energy vehicle manufacturing sector, Chinese automakers' competitiveness in the global market continues to strengthen, especially achieving significant breakthroughs in intelligence and connectivity, driving excellent stock performance of related listed companies.
III. AI Sector: Technological Breakthroughs and Application Scenario Expansion
The artificial intelligence sector is another hot sector. Since September, the AI index has risen by more than 7%, with sub-sectors such as AI hardware, AI algorithms, and AI applications all showing good performance. This performance is mainly due to the rapid iteration of AI technology and continuous expansion of application scenarios.
From the perspective of AI hardware, the demand for AI chips continues to be strong. As the parameter scale of large models continues to expand, the demand for computing power grows exponentially. At the same time, the acceleration of infrastructure construction such as edge computing and data centers drives the demand for AI chips. AI chip companies in the Hong Kong market occupy a favorable position in global market competition with technological innovation and cost advantages.
In the field of AI algorithms, large model technology continues to break through, with significant progress in multimodal AI, generative AI and other technologies. AI algorithm companies in the Hong Kong market have established competitive advantages in vertical fields through technology accumulation and data advantages.
In terms of AI applications, the commercialization process in fields such as intelligent driving, intelligent healthcare, and intelligent manufacturing is accelerating, bringing performance growth momentum for related listed companies. Especially in the field of intelligent driving, as L4 autonomous driving technology gradually matures, related industry chain companies are facing development opportunities.
IV. Capital Flow Analysis: Southbound Capital's Key Layout
In terms of capital flows, southbound capital has continued to increase its positions in the new energy and AI sectors recently. Data shows that since September, southbound capital has net purchased more than 15 billion Hong Kong dollars in the new energy sector and more than 10 billion Hong Kong dollars in the AI sector, showing international investors' optimism about these two sectors.
In terms of capital structure, southbound capital is mainly long-term allocation, focusing on leading companies with core competitiveness and growth potential. These companies usually have technical barriers, brand advantages, and scale effects, enabling them to maintain a leading position in industry competition.
Notably, northbound capital has also increased its allocation to the Hong Kong market recently, especially high-quality targets in the new energy and AI sectors. This shows international investors' confidence in China's economic transformation, upgrading, and technological innovation.
V. Investment Strategies and Risk Warnings
Based on the current market environment, investors can adopt the following strategies to participate in the investment of hot sectors in Hong Kong:
- Long-term allocation: For leading companies with core competitiveness and growth potential, a long-term holding strategy can be adopted to share industry growth dividends.
- Wave operation: For markets with obvious sector rotation, a wave operation strategy can be adopted to grasp sector rotation opportunities.
- Diversified investment: There are differences between different sub-sectors, and risks in a single field can be reduced through diversified investment.
- Focus on valuation: In the investment process, it is necessary to pay attention to the valuation level and avoid chasing highs and killing lows.
At the same time, investors also need to pay attention to the following risks:
- Policy risk: The development of the new energy and AI industries is greatly affected by policies, and policy changes may bring industry fluctuations.
- Technology risk: AI technology iteration speed is fast, and changes in technology routes may affect the competitive landscape of enterprises.
- Market risk: Changes in the global economic situation, geopolitical risks and other factors may affect the overall market performance.
- Liquidity risk: The liquidity of some Hong Kong stocks is relatively low, which may affect the trading experience.
VI. Future Outlook
Looking to the future, Hong Kong's new energy and AI sectors still have considerable growth space. From the perspective of the new energy sector, the global carbon neutrality process is accelerating, the penetration rate of new energy continues to increase, and the industry development prospect is broad. From the perspective of the AI sector, technological innovation continues to break through, application scenarios continue to expand, and the industry development momentum is strong.
At the same time, as the valuation advantage of the Hong Kong market becomes apparent, the willingness of international investors to allocate Hong Kong stocks increases, bringing incremental funds to the market. Especially against the background of the acceleration of the internationalization of the RMB, the Hong Kong market, as an important bridge connecting mainland China and international capital, its strategic position will be further enhanced.
Overall, under the dual drive of new energy and AI, Hong Kong's hot sectors are expected to welcome structural investment opportunities. Investors can focus on high-quality targets with core competitiveness and growth potential, and share industry growth dividends while controlling risks.
