From 2025 to early 2026, the Hong Kong stock market has welcomed two distinct yet directionally resonant streams of incremental capital. Mainland southbound capital set a new annual record with net purchases of HKD 1.41 trillion, establishing itself as the core architect of Hong Kong stock pricing power. Concurrently, Korean retail investors, characterized by concentrated bets, high-leverage trading, and a fervent pursuit of cutting-edge technology, have stirred structural waves in the market's periphery. One stream is defined by long-term allocation anchored in value, while the other is driven by high-frequency trading and industrial narratives. Together, they sketch a new map for the Hong Kong market, highlighting the diversification of funding sources and the stratification of pricing logic.
A significant hierarchical difference exists in the capital scale of southbound funds versus Korean retail investors in the Hong Kong market, yet each holds an irreplaceable role in terms of functional positioning and market influence. Southbound capital has been firmly established as the core source of incremental funds and a force reshaping the valuation framework of the Hong Kong market. By the end of 2025, cumulative net inflows from the south reached HKD 5.11 trillion, with net purchases in 2025 alone amounting to HKD 1.41 trillion—a figure nearly equivalent to the total of the previous three years (2022-2024). The market value of their holdings surpassed HKD 6.3 trillion, raising their share of the total Hong Kong market capitalization to 12.7%. This magnitude indicates that southbound capital has evolved beyond being a marginal supplement to become an endogenous pricing variable within the Hong Kong market.
In contrast, the capital volume of Korean retail investors in the Hong Kong market is relatively limited. However, their trading behavior is highly concentrated, exhibits significant leverage, and demonstrates strong community synchronization in decision-making. This enables them to exert short-term pricing pressure and shape liquidity premiums for specific targets—particularly new economy IPOs, semiconductor supply chain stocks, and leaders in artificial intelligence themes. At the beginning of 2026, Korean retail investors recorded net purchases of over USD 20 million in MiniMax-WP within a single month. The stock's IPO saw 1,837 times oversubscription, with Korean capital acting as a key catalyst for the valuation premium in the initial post-listing phase.
The two capital streams show a clear hierarchical differentiation in sector coverage, with limited overlap in favored industries, reflecting fundamental differences in capital nature, return objectives, and investment horizons. The financial sector and high-dividend utilities constitute an independent allocation domain for southbound funds. Stocks such as China Construction Bank (00939), Industrial and Commercial Bank of China (01398), Ping An Insurance (02318), China Mobile (00941), and China Shenhua Energy (01088) received systematic investments amounting to tens of billions of HKD from southbound capital. The core drivers for these investments are high dividend yields, low valuation percentiles, Renminbi-denominated asset characteristics, and assumptions of perpetual operation. Korean retail investors hold virtually no positions in this sector.
Southbound funds hold significant positions in Alibaba Group (09988) (with a HKD 191.3 billion increase in market value), Meituan (03690), and Tencent Holdings (00700). Their allocation logic has evolved from valuation recovery in 2024 to value reassessment in 2025, with holding behavior characterized by cross-cycle, low-turnover, and accumulation-on-dips strategies typical of allocation-oriented portfolios.
Korean retail investors heavily weighted Xiaomi Corporation (01810) in 2025 (with net purchases of USD 87.75 million) and quickly shifted to MiniMax-WP at the start of 2026 (USD 20.67 million). Their capital flows exhibit high flexibility, high turnover, and a strong narrative-driven nature typical of trading-oriented portfolios. Both groups share a systemic optimism towards Chinese tech leaders but show significant divergence in stock selection and holding periods.
In 2025, southbound funds were the dominant pricing force in the semiconductor sector, with net purchases of 508 million shares of SMIC (00981), increasing their holding value by HKD 36 billion. Korean retail investors contributed net purchases of USD 33.11 million during the same period, creating a two-tier pricing structure where the allocation portfolio provides stability and the trading portfolio offers momentum, collectively pushing the sector's valuation center higher.
At the beginning of 2026, Korean capital rapidly shifted towards stocks like Montage Technology (06809), Innoscience (02577), and Chinese semiconductor ETFs, demonstrating rotation within industrial sub-sectors and tool-based allocation. Southbound funds, meanwhile, continued their steady accumulation of SMIC, showing clear characteristics of allocation rigidity and holding inertia. This indicates a transition from strategic resonance to strategic divergence in the semiconductor sector, reflecting the different decision-making points of trading and allocation portfolios at various stages of the industrial cycle.
Horizon Robotics (09660) entered the top 20 list of southbound holdings for 2025 with a market value increase of HKD 21.4 billion, indicating that southbound funds have begun early-stage positioning in the smart驾驶 computing layer, though overall understanding remains in an introductory phase.
The IPO frenzy for MiniMax-WP was primarily driven by Korean retail investors—net purchases exceeding USD 20 million in a month and 1,837 times oversubscription. Their decision-making path exhibits typical features of strong community consensus and weak reliance on institutional analysis. Korean capital demonstrates a clear willingness to price risk premiums in this sector, providing a dual reference for southbound funds in terms of industrial narrative validation and valuation anchoring.
Stocks like BeiGene (06160), WuXi XDC Cayman (02268), and Ascletis Pharma (01672) show annual sector rotation within Korean retail holdings. Their entry and exit timing are highly correlated with global liquidity expectations and the U.S. stock biopharmaceutical index, representing trading portfolio behavior driven by global beta.
Automobile manufacturers such as BYD COMPANY (01211) and LI AUTO-W (02015) receive continuous foundational allocation from southbound funds. The decision anchors for these investments are penetration rate curves, capacity cycles, and global expansion validation, reflecting an allocation strategy focused on tracking industrial alpha. The maturity mismatch between trading and allocation portfolios is most evident in such high-valuation-elasticity, high-R&D growth sectors—Korean capital gambles on marginal changes, while southbound capital bets on the ultimate industrial outcome.
The trading behaviors of southbound funds and Korean retail investors present a fundamental contrast between institutionalization and retail participation, value anchoring versus narrative driving, and long-cycle versus high-frequency rotation.
The decision anchors for southbound funds include dividend yield, ROE stability, free cash flow generation capability, and valuation percentile. Their trading characteristics show continuous accumulation, contrarian buying, and holding stability. For example, during 2025's price fluctuations, southbound funds persistently made net purchases of 7.389 billion shares of China Construction Bank, increasing the holding value by HKD 55.8 billion. Buying more as prices fall is not emotional venting but a rational allocation behavior driven by rising dividend yields and strengthening margins of safety as prices decline.
Through sustained, predictable, and large-scale capital inflows, southbound funds are gradually converging the valuation systems of Hong Kong's financial and telecommunications sectors towards those of the A-share market. Their ownership stakes in stocks like China Construction Bank and China Mobile have already exceeded 20%.
The decision anchors for Korean retail investors are specifically the intensity of industrial narratives, social media buzz, and the concentration of community consensus. Their pricing logic is not based on what a company is worth, but on what price the next buyer is willing to pay. High leverage is a default setting for their trading. The number of active stock trading accounts in Korea reached 62 million, which is 1.2 times the total population; the peak balance of overseas stock margin lending exceeded KRW 18 trillion (approximately USD 12.6 billion). Notably, data from Korean exchanges shows that the average holding period for domestic individual investors' stock positions is less than three months, with turnover rates for some popular U.S. and Hong Kong stocks even exceeding those of certain cryptocurrencies. This stands in stark contrast to the holding periods of southbound funds, which are often measured in years.
High-frequency trading brings not only substantial commission fees—overseas stock trading commissions for 12 major Korean securities firms reached KRW 1.95 trillion in 2025—but also extreme sensitivity to sentiment. The label of gambling often attached to Korean retail investors is, in reality, a rational adaptation shaped by their institutional environment and industrial structure. While Korea is home to global semiconductor manufacturing giants, it lacks representative companies in soft technology areas such as internet platforms, cloud computing, and AI large language models, creating a compensatory trading impulse—heavy investment in Alibaba is a bet on the Amazon that Korea lacks, while scrambling for MiniMax is a search for the OpenAI that Korea doesn't have.
For the Hong Kong market, the influx of Korean retail investors represents both an incremental source of liquidity and an important step towards diversifying the investor base. They will not allocate to state-owned banks for dividends over years like southbound funds, nor will they meticulously scrutinize ESG data like international long-term funds. This type of capital can amplify volatility at certain times, but at other moments—such as during the MiniMax-WP IPO—it can directly reshape the pricing ecology of the initial listing phase.
In summary, southbound capital is reshaping the valuation foundation of the Hong Kong market with its trillion-HKD scale, while Korean retail investors are injecting liquidity premiums into peripheral areas through extreme trading. Two types of capital, two sets of logic, are jointly fostering a new normal for the Hong Kong market characterized by pricing stratification and parallel narratives—requiring both the steadfastness of allocation portfolios and the sharpness of trading portfolios.
