Policy Rumors Spark Market Attention
On July 28, 2026, an insider from HKEX revealed that a revision plan to optimize the Stock Connect mechanism is in the works. The core change is to lower the current market cap threshold of HKD 50 billion for inclusion, and add a batch of mid- and small-cap stocks with market caps between HKD 2 billion and HKD 5 billion into the Stock Connect scope. If implemented, this would be the most significant expansion of investable stock pool since the launch of Shanghai-HK Stock Connect in 2014.
Mid- and Small-cap Hong Kong Stocks to Receive Fresh Capital
As of end-June 2026, cumulative net southbound capital inflow via Stock Connect exceeded HKD 3.2 trillion, with daily average turnover accounting for about 18% of the main board total. However, under current rules, only about 600 stocks qualify for southbound trading, leaving many mid- and small-cap companies with growth potential excluded. The proposed adjustment aims to resolve this structural imbalance. An HKEX spokesperson responded informally: "We continuously listen to market voices and optimize the mutual market access mechanism to meet investors' diverse needs."
From a market cap perspective, among current Stock Connect stocks, those with market caps over HKD 50 billion account for over 70%, while those below HKD 10 billion account for less than 10%. If the threshold is lowered to HKD 2 billion, an estimated 200 to 300 mid- and small-cap stocks would be added to the investable list, covering sectors such as technology innovation, consumer services, and healthcare.
Opportunities and Challenges for Bootcamp Students
For HK Stock Connect Bootcamp students, this expansion is both an opportunity and a test. On one hand, the stock selection scope widens significantly, with more high-growth "small but beautiful" companies no longer constrained by liquidity discounts; southbound capital attention could trigger valuation recovery. On the other hand, mid- and small-cap stocks have higher volatility and lower information transparency, requiring stronger fundamental analysis and risk control capabilities from investors.
- Opportunity 1: Research potential inclusion targets in advance, focusing on niche leaders listed in Hong Kong but not yet fully covered, such as biotech, AI applications, and new energy materials.
- Opportunity 2: Leverage the liquidity premium from Stock Connect expansion to identify quality mid- and small-cap companies with PEG below 1.5x and revenue growth over 20%.
- Challenge 1: Beware of the "buy the rumor, sell the news" risk—some stocks may have been pre-traded during the rumor phase, leading to profit-taking after official implementation.
- Challenge 2: Hong Kong stock trading rules differ from A-shares, such as T+0, no price limits, and short selling mechanisms. Bootcamp students need to strengthen risk hedging awareness.
Strategy Adjustment Suggestions: From Large-cap Blue-chips to Growth Selection
For a long time, the core strategy of the HK Stock Connect Bootcamp has been "leading white horses + high dividends." In light of the new policy expectations, it is recommended that students adjust tactics in three phases:
Phase 1 (Before policy implementation): Lay low and set up surveillance
Based on HKEX's previous screening criteria (liquidity, market cap, listing time, etc.), build an observation pool of potential inclusion targets. Focus on companies meeting the following conditions: average daily turnover over HKD 10 million, market cap between HKD 2 billion and HKD 5 billion, and revenue growth over 15% year-on-year in the latest quarter. Focus can be on innovative pharmaceutical companies, fintech service providers, and high-end manufacturers listed on the HKEX Main Board.
Phase 2 (After policy announcement): Dynamic position building
After the official list is released, prioritize stocks being included for the first time with low institutional holdings (below 5%). Use the window of initial liquidity improvement, adopt a "batch building, pyramid scaling" approach, and keep initial position size no more than 15% of total capital. Also set a stop-loss line of 8% to prevent sharp declines due to insufficient liquidity.
Phase 3 (Normal trading): Refined operations
Include mid- and small-cap stocks into the Bootcamp's "growth stock pool," review financial data, industry conditions, and southbound fund flows quarterly. Combine technical analysis, focus on stocks breaking key resistance levels (e.g., MA60, MA120) with increased volume as a signal to add positions. Additionally, as the Hong Kong market is more susceptible to global capital flows, students should also monitor changes in the US dollar index and the Hong Kong dollar exchange rate.
Industry Interpretation: Incremental Capital Pathways and Risk Tips
Lin Qing, Chief Strategy Analyst at CICC, said in the latest report: "Expanding Stock Connect will enhance the global competitiveness and attractiveness of the Hong Kong market. In the short term, it is expected to attract about RMB 30-50 billion of incremental mainland capital into the mid- and small-cap segment; in the long term, it will help optimize the investor structure of the Hong Kong market and reduce over-reliance on a few large-cap stocks."
However, a senior instructor of the Bootcamp reminds students to note the following risks: First, mid- and small-cap Hong Kong stocks may have "scam stock" issues; risk screening should be done by checking corporate governance, dividend history, related-party transactions, etc. Second, the policy implementation timeline is uncertain; regulators may delay or adjust the plan due to market volatility. Third, southbound funds do not always buy; when external risks escalate (e.g., Fed rate hikes, geopolitical conflicts), the selling pressure on mid- and small-cap stocks is often greater.
Practical Case: Lessons from Past Expansion
Looking back at the inclusion of "B-share" biotech companies into Stock Connect in September 2023, the four newly included biotech stocks outperformed the Hang Seng Index by an average of 12.3 percentage points within three months, but later over the next six months, due to industry centralized procurement policy adjustments, their stock prices gave back most of the gains. This teaches Bootcamp students: do not ignore fundamental cycles just because of inclusion tailwinds; combine industry life cycles for right-side trading.
Summary: Standing at the Start of a New Cycle
The Stock Connect mechanism has been evolving in recent years, from stock pool expansion, trading calendar optimization, to the establishment of RMB counters, all reflecting the accelerating integration of the Chinese mainland and Hong Kong markets. The inclusion of mid- and small-cap stocks marks the transition of Hong Kong stock investing from a "large-cap era" to a "selection era." HK Stock Connect Bootcamp students should take this opportunity to refine their mid- and small-cap stock selection methodology and capture excess returns while controlling risks. In the coming week, HKEX will hold a market consultation, and more details are expected. We will continue to follow up and provide first-hand practical analysis for students.
