On August 1, 2026, major news hit the Hong Kong stock market: HKEX published its quarterly adjustment list for Stock Connect eligible securities, adding 19 stocks covering AI computing power, power batteries, innovative drugs, and new consumption. With two days until the change takes effect on August 3, smart money has already started positioning. This is the second large-scale expansion this year and one of the largest batches of new targets since the Stock Connect mechanism launched.
For mainland investors, Stock Connect is the most convenient gateway for "trading HK stocks." Volume data shows that in the first half of this year, Hong Kong stocks averaged HK$203 billion in daily turnover, with southbound capital contributing a record 24.6% for the period. This expansion undoubtedly gives mainland capital more options.
Stock Connect expands again: what signals do the new targets send?
Of the 19 newly added companies, 7 are from the tech sector, 5 are from the new energy supply chain, 3 are innovative drug makers, and the rest are in consumer and other services. The list includes many recent IPO unicorns, from AI chip designers to leading power battery material suppliers.
- AI computing power: Surging data-center computing demand has lifted earnings expectations for related hardware and SaaS companies.
- New energy: Energy-storage subsidy policies and the capacity-clearing cycle are resonating, with overseas orders picking up at leading firms.
- Innovative drugs: Several biopharma companies have received FDA fast-track designation, prompting a market re-rating of pipeline value.
An HKEX official said at a media briefing, "This round of adjustments reflects that more and more mainland investors want to participate in diversified asset allocation in the Hong Kong market, and we will continue to optimize the mutual market access mechanism." The move also means the pool of securities tradable via Stock Connect has expanded further, making capital channels smoother.
Why trade HK stocks? Three advantages support long-term allocation
Many mainland investors have long wondered: both A-shares and HK stocks have investment value, so why are more people choosing to "trade HK stocks"? In my view, the following three points are the core attractions.
1. Valuation and liquidity structures complement each other
Hong Kong stocks currently trade at an overall P/E of about 11.8x, lower than the CSI 300's 12.9x, and the Hang Seng Tech Index's P/E is also below its historical median. More importantly, HK stocks include scarce assets not available in A-shares, such as leading internet platforms, AI infrastructure companies, and globally oriented consumer brands. Through Stock Connect, mainland investors can share in the growth dividends of these companies.
2. Mature trading rules and diverse instruments
The HK market supports T+0 round-trip trading with no price limits, and also features a developed long-short system and derivatives such as ETFs and leveraged options. For professional investors focused on risk control, HK stocks offer more flexible hedging tools. For example, among the newly added targets are several high-volatility tech stocks, and investors can buy put options for protection while holding the spot positions.
3. Continuous inflow of southbound capital
In the first seven months of this year, cumulative net southbound inflows exceeded HK$300 billion, already approaching the full-year 2025 total. On the policy front, the expansion of Cross-boundary Wealth Management Connect 2.0 has enabled more mainland middle-class households to participate in HK stocks. Bank channel data shows that subscriptions to HK stock funds rose 30% month-on-month in July, with individual investor enthusiasm running high.
Newly added targets present both opportunities and traps
From the sector distribution of this adjustment, the policy-beneficiary direction is clear. AI and the digital economy remain the market's main theme, but valuations are no longer cheap in the short term. The new energy sector, after two years of correction, is now in a supply-demand rebalancing phase, with some leaders seeing margins recover first. Innovative drugs, catalyzed by out-licensing deals and medical insurance negotiations, are showing a cluster of right-side signals.
However, investors should also be cautious: some newly added stocks have small float and insufficient liquidity, making them prone to sharp swings. In 2025, a newly added target fluctuated more than 40% on its first trading day. Do not blindly chase highs; instead, screen by fundamentals and build positions in batches.
Risk warning: finding a balance between the pros and cons of HK stocks
No investment is just about advantages. HK stocks do carry some "hidden costs": as a mature market with a high proportion of institutional investors, individual stock valuations are more affected by external factors (Fed rates, geopolitical situation); the short-selling mechanism can lead to sharp drops when "black swan" events occur; and currency fluctuations can also erode returns. Therefore, "trading HK stocks" should not be an impulse, but rather part of overall asset allocation; it is recommended to keep the proportion within 20%-30% of investable assets.
Conclusion: expansion opens a new cycle, focus on long-term positioning
In short, the expansion of Stock Connect targets not only enriches the meaning of the mutual market access mechanism, but also responds to the real needs of mainland investors. In the coming years, the HK stock market will remain an important window for global capital to observe China's economy. For ordinary investors, leveraging professional institutions, downplaying short-term gaming, and focusing on long-term trends in quality tracks may be the right way to "trade HK stocks."
