Re-examination of Hong Kong Stock Investment Value: Hang Seng Index Valuation Still in Lowland, Institutional Dividends and Capital Water Dance Together

On August 5, 2026, after several days of volume increases, the Hong Kong stock market entered a high-level consolidation stage, with the Hang Seng Index repeatedly pulling around the 29,000-point mark. Although the index has rebounded more than 25% from its low point this year, the dynamic P/E ratio is still less than 11 times, significantly lower than 22 times for the S&P 500 and 13 times for the CSI 300. This rare valuation gap, coupled with multiple favorable factors such as continuous inflow of Southbound funds, optimization of Hong Kong Connect mechanism, and improvement of corporate governance, makes "trading Hong Kong stocks" again the focus of global investors. This article analyzes the underlying logic of Hong Kong's medium and long-term allocation value from four dimensions: valuation, system, capital and fundamentals.

One, the Valuation Lowland Effect is Still Obvious

Since the fourth quarter of 2025, the Hang Seng Index has been fluctuating and rising, but the structural undervaluation situation has not been completely reversed. As of August 5, more than 40% of the constituent stocks of the Hang Seng Index are still trading below book value per share, and the dividend yields of traditional sectors such as finance, energy, and real estate are generally over 5%, with some state-owned enterprise H-share dividend rates even exceeding 8%. In contrast, US tech stocks are at historical highs, and core assets in A-shares have also been repaired and are no longer cheap. As a bridge connecting China's fundamentals and global capital, Hong Kong's valuation discount provides a natural safety margin.

More importantly, the profit growth rate of the Hang Seng Index is recovering. According to Bloomberg consensus expectations, the overall profit growth rate of Hang Seng Index constituent stocks in 2026 is expected to reach 12.3%, with internet platforms, new energy vehicles and innovative drug sectors contributing the largest increments. The combination of profit growth and valuation expansion forms the basic conditions for "Davis double-click", which is the fundamental reason why long-term funds dare to continue adding positions near 29,000 points.

Two, Institutional Dividends Continue to be Released, Trading Rules are More Flexible

The Hong Kong stock market has always been known for its internationalization, openness and flexible trading rules. In recent years, HKEX has continuously promoted institutional reforms, further strengthening its attractiveness as China's offshore financial center. Since August 1, 2026, HKEX has officially implemented the new T+1 securities settlement rule, shortening the settlement cycle to one day, significantly reducing capital occupation costs and reducing overnight risks. At the same time, after upgrading the closing auction mechanism and the second-generation automatic matching system, the liquidity depth and trading efficiency of Hong Kong stocks have been greatly improved, providing a more friendly environment for high-frequency trading and institutional strategies.

More importantly, the expansion of Hong Kong Connect ETFs and the expansion of interconnection targets allow mainland investors to directly participate in the allocation of Hong Kong core assets in RMB. Currently, Hong Kong Connect covers over 90% of the constituent stocks of the Hang Seng Composite Index, and allows eligible different share classes and second-listed companies to be included. This "no-threshold" allocation channel allows ordinary investors to also share the growth dividends of new economy giants such as Meituan, Xiaomi, and Kuaishou. Compared with A-shares, Hong Kong stocks have no daily price limit, support T+0 round-trip trading, and have complete tools for both long and short (such as bull/bear certificates, options, futures), which can not only meet the flexible needs of short-term traders, but also provide rich hedging tools for long-term investors.

Table: Comparison of Core Trading Rules Between Hong Kong Stocks and A-shares

• Trading Time: Hong Kong continuous trading time is 09:30-16:00 (lunch break 12:00-13:00), longer than A-shares;
• Settlement Cycle: Hong Kong T+0 round-trip trading, T+2 settlement (shortened to T+1 under new rules); A-shares T+1 trading, T+1 settlement;
• Price Limit: Hong Kong has no price limit, A-shares main board ±10%, Sci-tech Innovation Board/ChiNext ±20%;
• Short Selling Mechanism: Hong Kong allows short selling of individual stocks and index derivatives, while A-shares have high thresholds for margin trading and limited sources of securities;
• Investor Structure: Hong Kong is dominated by institutional investors (over 60%), while A-shares have a larger proportion of retail investors.

Three, Southbound Funds Continue to Inflow, Global Capital Increases Allocation to Chinese Assets

Capital flow is the most intuitive indicator to measure market attractiveness. As of August 4, 2026, Southbound funds have maintained net purchases for 15 consecutive trading days, with a cumulative net inflow exceeding HK$420 billion this year, a 55% increase over the same period last year. Among them, the average daily net purchase of Southbound funds in the first week of August exceeded HK$8 billion, setting a new high for the same period since the launch of the interconnection mechanism. The inflow direction is concentrated on high-dividend banks, power operators and internet leaders, reflecting the pursuit of high-cost-performance assets in Hong Kong by institutions.

In terms of international capital, EPFR data shows that since late July, the allocation proportion of global emerging market funds to the Hong Kong market has increased from 3.2% to 5.8%, reaching the highest level in nearly three years. Against the background of the end of the Fed's interest rate hike cycle and entering the interest rate cut expectation, the decline in US Treasury yields makes the risk premium attractiveness of Hong Kong stocks prominent. Global asset management giants BlackRock and Vanguard have both upgraded their Hong Kong ratings in the recently released Q3 asset allocation reports, believing that Hong Kong stocks are in the best combination window of "low valuation + profit turning point + marginal liquidity easing".

Four, Fundamental Improvement: Buyback Tide and Dividend Culture Restructuring Value Investment Logic

The shareholder return awareness of Hong Kong listed companies is awakening. Since 2026, the cumulative buyback amount in the Hong Kong stock market has exceeded HK$180 billion, a historical high for the same period. Weighted stocks such as Tencent, HSBC Holdings, and AIA have increased buybacks, and some state-owned enterprises have increased their H-share dividend ratios to over 50%. The dual drive of buybacks and dividends effectively supports stock prices and also improves long-term investment expectations in the market.

At the same time, the governance level of Hong Kong companies continues to improve. HKEX requires listed companies to fully disclose ESG reports by the end of 2026 and establish independent compensation committees. More companies are beginning to use differentiated voting arrangements other than "different share classes" to balance the interests of founding teams and ordinary shareholders. These institutional changes are making Hong Kong stocks gradually transform from a "value trap" to a "value lowland", attracting a batch of long-term funds that focus on shareholder returns.

Five, Risk Reminders and Investment Suggestions

Although the allocation value of Hong Kong stocks is prominent, investors should still be alert to potential risks. First, the Hong Kong market is highly sensitive to global liquidity, and the uncertainty of the Fed's interest rate cut path may cause fluctuations in exchange rates and capital flows. Secondly, Hong Kong stocks have severe structural differentiation, small and medium market value stocks have poor liquidity and are easily manipulated, ordinary investors should prioritize liquid large-cap blue chips or Hong Kong Connect ETFs for allocation. Finally, geopolitical risks still exist, and international sanctions or capital control rumors may cause short-term shocks.

For mainland investors, it is recommended to diversify investment through Hong Kong Connect channels or genuine Hong Kong ETF products, and avoid blindly chasing individual stocks. First, you can focus on Hang Seng High Dividend ETF to obtain stable cash flow; second, you can allocate to Hang Seng Tech Index to grasp the internet sector rebound opportunities; third, pay attention to the arbitrage opportunities of AH premium rate convergence. For investors with larger funds, you can use Hong Kong's options and bull/bear certificates for risk hedging, but you need to fully understand the leverage characteristics of derivatives.

In summary, as one of the world's lowest-valued major stock markets, Hong Kong is welcoming the resonance of three forces: institutional dividends, profit recovery, and capital inflow. In the second half of 2026, after the Hang Seng Index stabilizes above 29,000 points, the market may shift from a general rise to a structural market. Those companies with core competitiveness, willing to return to shareholders, and in line with the new economy direction will become the winners who can cycle through. "Trading Hong Kong stocks" is not a simple speculative game, but a value discovery based on in-depth research. For investors who have not yet opened Hong Kong Connect, the current time may be a window to position in this historical valuation recovery process.
