Hang Seng Index Posts Six-Day Winning Streak, Reclaims 23,000 as Tech Stocks Lead; Southbound Flows and External Factors in Focus

Hong Kong's Hang Seng Index posted gains for six consecutive trading sessions this week, reclaiming the 23,000-point mark and signaling a notable improvement in market sentiment. The rebound is not driven by a single factor but is the result of sustained inflows from mainland capital, a recovery in global risk appetite, and improving fundamental expectations for the tech sector. However, beneath the index's strength, structural shifts and potential divergences in capital flows are setting the stage for future market movements.

Southbound Capital: The 'Anchor' of Consecutive Net Inflows

According to public data from the Hong Kong Stock Exchange, southbound capital has maintained a streak of net inflows, becoming one of the core forces supporting the Hang Seng's upward move. Since the start of this rebound, cumulative net purchases via southbound trading have been substantial, with the tech sector (e.g., internet platforms, semiconductor design) and high-dividend financials being the primary targets. Market analysts suggest that mainland institutional investors are increasing their allocation to Hong Kong stocks as part of a broader strategy to tap undervalued assets and diversify their renminbi-denominated portfolios over the long term.

Notably, the pace of southbound inflows has not been uniform. On the key trading day when the Hang Seng broke above 23,000, daily net purchases surged, indicating strong conviction among mainland funds in confirming the breakout. However, in the following sessions, net buying narrowed as some short-term funds took profits, while long-term allocators continued to steadily add positions. This coexistence of 'steady drip' and 'pulse-like' inflows suggests strategic divergence within the capital pool.

External Linkages: Fed Policy Expectations and Global Risk Appetite

As an offshore market, Hong Kong is highly sensitive to shifts in global liquidity. Recently, U.S. inflation data showed signs of cooling, boosting expectations for multiple Fed rate cuts this year. According to the latest Federal Reserve meeting minutes, most officials believe 'the need for further tightening has diminished,' which was interpreted as a dovish signal, weighing on the U.S. dollar index and stabilizing the renminbi exchange rate, thereby benefiting Hong Kong stock valuations.

Meanwhile, global equity risk appetite has recovered, with U.S. tech stocks surging on the artificial intelligence boom and the Nasdaq repeatedly hitting record highs. According to Bloomberg data, the MSCI Asia Pacific Index (ex-Japan) has posted positive returns this month, moving in tandem with the Hang Seng. Hong Kong's tech sector has high correlation with U.S. tech stocks, especially large internet companies whose valuations are partly anchored to overseas comparables. Thus, the strong performance of external tech names has directly lifted sentiment for local tech leaders.

Tech Stocks Lead: Earnings Expectations and Capital Preferences Align

In this rebound, tech stocks have been the undisputed leaders. The Hang Seng Tech Index has significantly outperformed the broader Hang Seng Index, with major heavyweights like Tencent, Alibaba, and Meituan posting substantial gains. Three key drivers are at play:

• Improved earnings expectations: Recent quarterly reports from several internet companies show that cost-cutting and efficiency measures are paying off, with year-on-year margin improvements, and new businesses such as cloud services and AI large models are beginning to contribute incremental revenue. According to sell-side research, market forecasts for tech sector earnings growth over the next 12 months have been revised up from low single digits to high single digits.
• Stabilizing policy environment: Platform economy regulation has entered a normalized phase, and concerns about policy uncertainty have significantly eased. Regulators have repeatedly emphasized 'supporting platform enterprises to fully leverage their strengths,' providing policy backing for valuation recovery in the sector.
• Low crowding: Despite the consecutive gains, tech valuations remain at mid-to-low levels relative to historical averages. According to Wind data, the Hang Seng Tech Index's forward P/E ratio is still about 20% below its five-year average, attracting incremental capital inflows.

However, the tech sector is not monolithic. Capital is clearly favoring leaders with solid earnings, while some small- and mid-cap tech names have seen limited gains or even pullbacks. This '80/20 divergence' suggests that the rally is more fundamentally driven than speculative, but it also means that further index upside requires sustained earnings delivery.

Undercurrents: Divergences and Concerns

Behind the index's shine, capital flows reveal undercurrents. On one hand, subscriptions to passive ETFs (exchange-traded funds) via southbound trading have increased notably, indicating that some funds are index-tracking passive allocations rather than active stock picks, which could amplify volatility during market turns. On the other hand, the actions of international funds (the counterpart to northbound flows in the Stock Connect) are not uniform. According to CCASS data, some foreign investment bank seats showed net selling during the Hang Seng's rally, while mainland funds absorbed those sell orders. This exchange of chips means that the sustainability of the rally depends on whether mainland capital can continue to absorb foreign selling pressure.

Additionally, the Hong Kong dollar has strengthened recently, touching the strong-side Convertibility Undertaking, reflecting capital inflows into the market. However, despite loose HKD liquidity, the aggregate balance of the Hong Kong banking system has not increased significantly, suggesting that some funds may be entering through other channels (e.g., equity-linked notes) rather than directly settling in the banking system, adding complexity to the flow picture.

Outlook: Watch Volume and Policy Signals

After reclaiming 23,000, the Hang Seng faces technical resistance from a previous dense trading zone. Market participants generally believe that two key variables will determine the path forward: first, whether trading volume can continue to expand—if average daily turnover remains elevated (e.g., above HK$200 billion), the rebound's foundation is solid; second, whether further policy catalysts from the mainland emerge, such as fiscal stimulus details or capital market reforms.

In summary, the Hang Seng's six-day winning streak is the result of a triple convergence of capital flows, sentiment, and fundamentals. Sustained southbound inflows provide a solid floor, external easing expectations open up room for valuation repair, and improving tech earnings have ignited a structural rally. But the intra-capital dynamics and divergences also remind investors to remain cautious amid optimism. In the coming weeks, if the Hang Seng can hold above 23,000 and break out on expanding volume, a new upward leg could begin; otherwise, the market may enter a phase of high-level consolidation.
