On July 28, 2026, the Hong Kong Exchange announced a reduction in stock trading stamp duty from 0.1% to 0.05% effective August 1, alongside optimizing trading mechanisms by shortening settlement cycles. The same day, China Securities Regulatory Commission issued new rules easing the cap on mutual fund investments in Hong Kong stocks, allowing equity funds to allocate up to 50% of assets to HK stocks. These two major positive policies together triggered a re-evaluation of HK stock investment value.
I. Double Policy Boons: HK Stocks Enjoy Institutional Dividends
This stamp duty cut by HKEX is another relief after 2023. In August 2023, HKEX reduced stamp duty from 0.13% to 0.1%, and now further to 0.05%, with a cumulative reduction of over 60%. Based on an average daily turnover of HKD 150 billion, investors could save around HKD 15 billion in trading costs annually. Concurrently, the CSRC loosened the mutual fund investment limit from 20% to 50%, potentially unleashing over one trillion RMB of incremental funds.
These two policies directly boosted HK stock liquidity and appeal. The Hang Seng Index rose 4.32% cumulatively in the two days after the announcement, led by tech and financial stocks, while southbound capital saw a net inflow of over HKD 30 billion in a single day, a new high for the year.
II. Core Advantages of Investing in HK Stocks: Why They're Worth It
1. Valuation Discount: Lowest Among Major Global Markets
As of July 29, 2026, the Hang Seng Index had a P/E ratio of only 9.8x and a P/B ratio of 0.95x, at historic lows, far below the S&P 500's 22x and the CSI 300's 13x. Many HK-listed companies (especially state-owned and financials) offer dividend yields over 5%, providing a high margin of safety.
2. Rich Investment Targets: Globalized and Diversified
HK stocks gather numerous high-quality mainland enterprises (e.g., Tencent, Alibaba, Meituan), while also providing opportunities in international companies (e.g., HSBC, AIA) and emerging sectors (biotech, new energy). Additionally, the HK market includes REITs, ETFs, and various derivatives like CBBCs, catering to different risk appetites.
3. Free Capital Port: A Bridge for Global Allocation
Hong Kong operates a linked exchange rate system with free capital movement and no foreign exchange controls. For mainland investors seeking overseas asset allocation, the Stock Connect provides a convenient channel. Moreover, HK stocks are highly correlated with global markets and can serve as a hedge against A-share risks.
4. Continuous Policy Optimization: More Friendly Trading Mechanisms
Recently, HKEX introduced several reforms: shortening settlement cycles (T+0 trading, T+2 settlement changed to T+1), reducing stamp duty, and broadening market volatility control mechanisms. These measures significantly enhance trading efficiency and reduce implicit costs.
III. Potential Risks and Considerations
- Exchange Rate Risk: HK stocks are denominated in HKD, which is pegged to the USD, but RMB exchange rate fluctuations can still impact actual returns.
- High Volatility: HK stocks are influenced by global capital flows, prone to sharp surges and drops, especially small-cap stocks with low liquidity.
- Trading Rule Differences: HK stocks have no price limits and allow T+0 trading; investors need to be familiar with the rules to avoid operational errors.
- Information Asymmetry: Some companies' financial disclosures are less detailed than those of mainland counterparts, and delisting mechanisms are stricter.
IV. Investment Strategy Suggestions
For novice investors, it is recommended to start with index funds (e.g., Tracker Fund of Hong Kong) or blue-chip stocks with high dividend yields, avoiding blind chasing of concept stocks. More experienced investors may focus on agricultural sector stocks in the Stock Connect (e.g., COFCO Joycome, China Starch), which recently benefited from an uptrend in agricultural product prices. Meanwhile, using the short-selling mechanism in HK stocks can hedge risks. In the long run, with mainland economic recovery and improved HK stock regulations, HK stocks as a global valuation haven are increasingly attractive for allocation.
In summary, driven by policy dividends, low valuations, and diversified targets, HK stocks are ushering in a new investment window. However, investors should still make prudent decisions based on their own risk tolerance.
