On July 30, 2026, The Hong Kong Stock Exchange (HKEX) announced further optimization of its listing structure and expansion of the scope of cross-border connectivity with the mainland, planning to include more new economy and biotechnology enterprises in HK Connect. This policy move has attracted widespread market attention and once again made HK the focus of global investors. Why is HK investment value becoming increasingly prominent at the current time point? This article will provide an in-depth analysis from three perspectives: valuation, institutions, and capital, to sort out the underlying logic for investors to allocate to HK.
1. HK Valuation at Historical Low, Global Capital Basin Effect Significant
If one word could summarize the current characteristics of HK stocks, it would be "cheap". As of the end of July 2026, the Hang Seng Index's P/E ratio is about 9 times, with a P/B ratio of only 1.0, significantly lower than the S&P 500's 21 times P/E ratio and the A-share CSI 300's 13 times P/E ratio. At the same time, HK's dividend yield exceeds 4.5%, far above the average of major global markets, forming an attractive "safety cushion".
Behind this valuation discount, there are both historical structural factors and opportunities for mean-reversion investment. Global funds often seek certain returns during central bank easing cycles, and HK's low valuation and high dividends恰好 meet this demand. More importantly, as the mainland economy stabilizes and recovers, HK corporate profits have entered an upward cycle, providing fundamental support for valuation recovery. Historical data shows that when the Hang Seng Index P/E ratio is below 10, the probability of achieving positive returns in the next three years exceeds 85%. This is a typical "low valuation + profit growth" double opportunity.
2. Institutional Advantages and Policy Dividends Resonate, HK Connectivity Continues to Deepen
HK has an international and legal mature market system, with listed companies from all over the world, and highly flexible trading mechanisms supporting T+0 trading, no price limits, and short selling mechanisms, providing professional investors with rich strategic tools. More importantly, HK's listing system keeps pace with the times. Since the 2018 reform, it has allowed different shareholding structures, unprofitable biotechnology companies, and secondary listings of Chinese concept stocks, attracting many new economy leaders to list in HK.
In the second half of 2026, the connectivity mechanism is upgraded again. HKEX and mainland regulators jointly announced that they will expand the scope of HK Connect, including more qualified small and medium-cap technology innovation enterprises. At the same time, ETF connectivity varieties will be further broadened, and the investment scope of southbound funds continues to expand. This policy dividend directly opens up channels for mainland capital to allocate to HK, bringing continuous incremental funds. According to statistics, southbound funds accumulated a net inflow of over 500 billion HKD in the first half of 2026, far more than the same period last year, and foreign capital is also accelerating its layout driven by low valuation. The optimization of institutions and the southward flow of capital form a resonance, significantly enhancing the liquidity and pricing power of the HK market.
3. New Economy Sector Layout Value Highlights, Rare Targets Favored by Global Capital
One of the greatest charms of the HK market is its unique "rare asset pool". From internet giants Tencent, Alibaba, Meituan, to new energy vehicle leaders BYD, NIO, to innovative drug leader BeiGene, HK concentrates a large number of China's new economy core assets. These companies are either absolute industry leaders or pioneers in niche tracks, providing investors with differentiated allocation choices different from A-shares.
In the first half of 2026, the global technology industry has ushered in a new round of AI industrialization wave, with profit expectations for HK technology sectors continuously revised upward. At the same time, many unprofitable biotechnology companies have successfully listed under HKEX's new regulations, making HK the largest biotechnology fundraising center in Asia. For global investors, HK is an ideal window to share China's innovation dividends. Compared to direct A-share allocation, HK has greater convenience in cross-border capital flow, exchange rate hedging, and information disclosure, and some AH shares have obvious discounts, providing value investors with arbitrage opportunities for same rights.
4. Risk Warnings: Three Variables to Be Alert for HK Investment
Although HK has multiple advantages, investment always comes with risks. First, global monetary policy uncertainty remains, and repeated Federal Reserve interest rate paths may cause violent capital flow fluctuations in emerging markets, with HK being highly sensitive to dollar liquidity; second, HK's short selling mechanism is mature, individual stocks may experience violent fluctuations, especially small and medium-cap stocks with insufficient liquidity are easily manipulated; third, the recovery slope and policy transmission effect of the mainland economy are uncertain, and if corporate profits do not meet expectations, valuation recovery may be delayed.
Therefore, when allocating to HK, investors are advised to prioritize high-dividend blue-chip stocks and index ETFs (such as Hang Seng ETF, HK Connect Technology ETF) to diversify stock risks; at the same time, pay attention to HK Connect capital flows and Hang Seng Index component adjustments, and build positions in batches according to their own risk preferences, avoiding chasing gains and selling at losses. In the long run, HK as a bridge connecting China and the world has irreplaceable strategic value, and rational layout will eventually reap the rewards of time.
