Valuation Depression Effect Persists, HSI P/E Far Below Major Global Markets
Entering August 2026, global capital market volatility intensified under the interplay of multiple factors such as US election expectations, fluctuating Fed rate cut paths, and geopolitics. However, the HK stock market continues to attract global capital seeking safety margins with its rare valuation discount. As of the morning session on August 4, although the Hang Seng Index fluctuated around 23,800 points, its overall P/E ratio maintained at around 9.8x, not only far below the S&P 500's 22x, but also lower than the Nikkei 225 and Euro Stoxx 50. This cross-market valuation depression effect is the most intuitive quantitative answer to the proposition of "why allocate to HK stocks".
AH Premium Rate Running High, Same Shares Same Rights Different Prices Highlights Arbitrage Space
More crucially, the Hang Seng Stock Connect AH Premium Index has recently continued to run high in the 145 to 150 range, meaning A-shares have an average premium of over 45% relative to H-shares. For dual-listed companies listed in both the mainland and Hong Kong, HK stock prices are clearly cheaper. This price difference not only provides value investors with a higher safety cushion, but also indicates that against the backdrop of increasingly mature mutual market connectivity mechanisms, as southbound capital continues to flow south, price convergence will be a highly probable long-term event. Allocating to HK stocks currently is equivalent to buying core Chinese assets at a "discounted" price.
Southbound Capital Surging in "SIP-style", Net Inflow Hits New High This Year
Capital flow is the most authentic voting machine. Data shows that since 2026, southbound capital has continued its previous strong momentum, achieving single-month net inflows of over 100 billion HKD for 8 consecutive months as of early August, with cumulative net purchases exceeding 1.1 trillion HKD, far exceeding the same period last year. This continuous capital inflow is not simple short-term speculation, but a strategic allocation to high-dividend and scarce assets in HK stocks by mainland institutional and retail investors under the backdrop of an "asset drought". Traditional high-yield sectors like banks, energy, and telecoms, as well as core tech stocks like internet leaders and AI computing power, have become the key targets for southbound capital.
High Dividend Assets: The "Scarce Stabilizer" of the Low-Interest Rate Era
In the macro environment of global low or even negative interest rates, the high-dividend characteristic of HK stocks has become one of its strongest attractions. The dividend yield of the Hang Seng High Dividend Yield Index currently exceeds 6%, significantly higher than the A-share CSI 300 Index and the US 10-year Treasury yield. Especially against the backdrop of expectations for gradual optimization of the Stock Connect dividend tax policy, the actual net yield for mainland investors holding high-yield stocks via Stock Connect is expected to further improve. For insurance funds, pensions, and prudent retail investors seeking stable cash flows, allocating to high-dividend HK stock assets is not only a way to obtain excess returns, but also an indispensable "stabilizer" in their asset portfolios.
AI and Tech Growth: HK Stocks' Unique Internet Ecosystem Moat
Besides high-dividend defense, HK stocks also possess irreplaceable allocation value in the tech growth sector. The HK stock market gathers top Chinese internet platform companies like Tencent, Alibaba, Meituan, and NetEase. After experiencing regulatory reshuffles in previous years, these companies are currently entering a dual dividend period of "cost reduction and efficiency enhancement" and "AI empowerment". Since 2026, leading internet companies have successively increased investments in AI large models and begun exploring commercial monetization in e-commerce, cloud computing, and gaming scenarios. Compared to A-shares, HK stocks' internet ecosystem is more complete, and valuations remain at historical mid-to-low levels. As AI technology extends from hardware computing power to application ends, the earnings repair expectations for HK tech stocks are strengthening, providing investors with growth elasticity distinct from traditional blue chips.
International Allocation and FX Hedging: A Natural Barrier to Diversify Single Market Risk
Another core logic of allocating to HK stocks lies in portfolio diversification. As an offshore financial market, HK stocks are greatly influenced by global liquidity, and their trends exhibit obvious correlation-complementing characteristics with A-shares. When the A-share market enters a volatile adjustment period, HK stocks often show stronger resilience due to lower valuations. In addition, for investors holding RMB assets, investing in Stock Connect targets actually indirectly allocates HKD assets. The linked exchange rate system pegging HKD to USD provides investors with a natural FX risk hedging tool. Against the backdrop of increased RMB exchange rate volatility, achieving soft asset diversification through HK stock allocation is an effective means to optimize the overall investment portfolio.
Stock Connect Mechanism Evolves Again: Lowered Thresholds and Expanded Targets
With the HKEX continuing to deepen reforms, simplifying secondary listing thresholds and expanding Stock Connect targets multiple times a year, channels for mainland investors to reach high-quality HK assets have become smoother. The latest new economy stocks included in Stock Connect cover more segmented leaders in consumer retail and biopharmaceuticals, further enriching the investable scope. The optimization of trading mechanisms means mainland capital "going south to the sea" has no institutional barriers, making investing in HK stocks as convenient as investing in A-shares. The continuous release of this institutional dividend constantly consolidates HK stocks' strategic position as the bridgehead for Chinese capital markets to go global.
Short-term Risk Warning: Global Liquidity Volatility and Policy Disturbances
Although the allocation logic is solid, investors still need to be wary of short-term risks. Although the Fed's September rate cut expectation has risen to 85%, if inflation data fluctuates, it may trigger a reversal in global liquidity expectations, impacting HK stocks in the short term. In addition, geopolitical frictions and high-level volatility in US tech stocks may also affect the HK stock market through sentiment transmission. When formulating HK stock allocation strategies, investors are advised to adopt a "barbell" allocation: one end being high-dividend, low-valuation state-owned enterprises for stable dividends; the other end being tech leaders with AI application potential to capture growth elasticity, thereby maintaining a balance of offense and defense in a volatile market environment.
