Southbound Funds Increase AI and New Energy Exposure in September: HK Stock Market Structural Opportunities Further Enhanced, Institutions Bullish on Second-Half Performance
In September 2026, the HK stock market welcomed continuous inflows of southbound funds, with capital focusing on the two hot sectors of artificial intelligence and new energy, injecting new vitality into the market. According to the latest data, the net inflow of southbound funds in September reached a record 50 billion HKD, with the AI and new energy sectors becoming the main destinations for capital. This trend not only reflects global investors' confidence in the HK stock market but also indicates that the HK stock market will see structural investment opportunities in the second half of the year.
Analysis of Southbound Fund Flows: AI and New Energy Become New Favorites
Southbound funds, which flow from the mainland to the HK stock market through the Stock Connect channels, have always been an important source of capital for the HK stock market. Since 2026, the cumulative net inflow of southbound funds has exceeded 500 billion HKD, setting a new historical high. In September, this trend became more pronounced, with capital not only continuing to flow in but also showing clear sector preferences.
Data shows that in September, the net purchase amount of southbound funds in the AI sector reached 20 billion HKD, with significant increases in holdings of tech giants like Tencent Holdings and Alibaba. At the same time, the new energy sector attracted capital inflows of about 15 billion HKD, mainly concentrated in leading enterprises such as BYD and CATL. This change in capital flow reflects investors' optimistic expectations for the future development of the tech and new energy industries.
Notably, the inflow of southbound funds in September showed a clear "structural" characteristic. In addition to AI and new energy, high-dividend sectors also received stable capital inflows, indicating that investors are paying attention to risk control and return stability while pursuing growth. This diversified investment strategy helps reduce the overall risk of the investment portfolio.
AI Sector: Technological Innovation Drives Valuation Increase
As a hot spot in current global technological development, artificial intelligence has also gained favor from southbound funds in the HK stock market. In September, the AI sector's gain exceeded 15%, with the stock prices of tech giants like Tencent Holdings and Alibaba reaching new highs for the year. Behind this performance is the rapid development of AI technology and the continuous expansion of application scenarios.
As the AI leader in the HK stock market, Tencent Holdings' stock price rose 12% in September, with its market cap exceeding 4 trillion HKD. The company's layout in areas such as large models and cloud computing, as well as its cooperation with domestic and international enterprises, has brought new growth momentum. Alibaba also performed strongly, with its stock price rising 10%, and its investments in AI chips, autonomous driving, and other fields beginning to show results.
In addition to leading enterprises, some small and medium-sized AI companies have also attracted the attention of southbound funds. For example, a company focused on AI chip design saw its stock price rise by more than 20% in September. Although these companies are smaller in scale, they have obvious competitive advantages in specific fields and have high growth potential.
Institutional analysts point out that the valuation increase of the AI sector not only reflects the market's optimistic expectations for technological development but also demonstrates investors' confidence in the profitability of the AI industry. As AI technology is increasingly applied in various industries, the performance of related companies is expected to continue to improve, providing support for stock prices.
New Energy Sector: Dual Drivers of Policy Support and Market Demand
The new energy sector was another key focus of southbound funds in September. Driven by the global carbon neutrality goal, the new energy industry has broad development prospects, attracting significant attention from capital. In September, the new energy sector's gain exceeded 10%, with the new energy vehicle and energy storage sectors performing particularly well.
As the new energy leader in the HK stock market, BYD's stock price rose 15% in September, with its market cap exceeding 800 billion HKD. The company's sales in the domestic market continued to grow, and it also made breakthroughs in overseas markets. In addition, BYD's innovations in battery technology, new energy vehicles, and other aspects have won market recognition.
As the global leader in power batteries, CATL's stock price rose 12% in September, with its market cap approaching 2 trillion HKD. The company's advantages in battery technology, energy storage systems, and other fields have enabled it to occupy a leading position in the global market. As global demand for new energy increases, CATL's performance is expected to continue to grow.
In addition to leading enterprises, some companies in the new energy industry chain have also attracted the attention of southbound funds. For example, a company focused on photovoltaic materials saw its stock price rise by more than 18% in September. These companies play an important role in the industry chain, and as the new energy industry develops, their performance is expected to continue to improve.
Institutional analysts believe that the rise of the new energy sector is not only influenced by policy support but also reflects the market's confidence in the profitability of the new energy industry. As global demand for new energy increases, the performance of related companies is expected to continue to improve, providing support for stock prices.
High-Dividend Sectors: Balancing Risk Control and Stable Returns
In the southbound fund flows in September, high-dividend sectors also received stable capital inflows. This trend reflects that investors are paying attention to risk control and return stability while pursuing growth. High-dividend sectors usually include industries such as banking, insurance, and utilities, where companies have stable cash flows and high dividend yields.
In September, the high-dividend sector's gain was about 5%, with the banking and insurance industries performing relatively well. For example, the stock prices of companies like HSBC Holdings and AIA Group rose by more than 8% in September. These companies have high dividend yields and stable performance, attracting investors with lower risk preferences.
Institutional analysts point out that the stable performance of high-dividend sectors provides investors with a balance of risk control and stable returns. In a volatile market, high-dividend sectors can be part of an investment portfolio to reduce overall risk.
Outlook for Second-Half Market: Structural Opportunities and Risks Coexist
With the continuous inflow of southbound funds and sector rotation, the HK stock market is expected to see structural investment opportunities in the second half of the year. Institutional analysts are generally optimistic about the performance of the HK stock market, believing that driven by hot sectors like AI and new energy, the market is likely to continue to rise.
However, investors also need to pay attention to risk factors in the market. First, the uncertainty of the global economic situation may affect market sentiment. Second, geopolitical risks may impact the market. In addition, some sectors have already reached high valuations, posing a risk of correction.
For investors, it is recommended to adopt a diversified investment strategy, focusing on hot sectors like AI and new energy while also allocating to defensive sectors such as high-dividend and low-valuation ones to balance risk and return. At the same time, closely monitor market dynamics and changes in capital flows to adjust the investment portfolio in a timely manner.
Investment Strategy Recommendations
- Focus on AI and New Energy Sectors: These two sectors are the mainstream hot spots in the current market, with high growth potential and investment value. Investors can focus on leading enterprises and also consider some small and medium-sized companies with competitive advantages.
- Allocate to High-Dividend Sectors: High-dividend sectors can provide stable returns and reduce the risk of the investment portfolio. Investors can focus on industries such as banking, insurance, and utilities, choosing companies with higher dividend yields.
- Diversified Investment: Avoid concentrating investments in a single sector or company. Adopt a diversified investment strategy to reduce overall risk. You can allocate to companies of different industries and sizes to diversify risk.
- Closely Monitor Market Dynamics: Keep abreast of market dynamics and changes in capital flows to adjust the investment portfolio. For example, if the capital inflow into a sector suddenly increases, you can consider appropriately increasing allocation; if the capital outflow from a sector increases, you can consider appropriately reducing allocation.
- Long-Term Investment Perspective: Avoid short-term speculation and adopt a long-term investment perspective. The rise of hot sectors like AI and new energy may take time, and investors need to be patient, waiting for performance improvement and valuation increase.
