Since early 2025, the US, A-share, and Hong Kong markets have exhibited quarterly rotations, featuring both a "seesaw effect" and cross-market correlations. In Q1, DeepSeek led a revaluation of Chinese assets, with the Hang Seng Tech Index outperforming. In Q2, after US tariff adjustments, US stocks surged on stronger-than-expected earnings and capex from AI leaders, while Hong Kong’s new consumer and biotech sectors gained traction—though the Hang Seng Tech Index never reclaimed its March peak. Q3 saw A-shares rally on domestic capital inflows and a computing power-driven tech rebound, while September’s "loosening trade" and AI narratives around Chinese internet giants briefly lifted Hong Kong again.

However, since late November, Hong Kong has lagged significantly, with the Hang Seng China Enterprises Index down 2.2% and the Hang Seng Tech Index falling 0.7%. In contrast, the CSI 300 rose 0.5%, while the S&P 500 and Nasdaq gained 5.5% and 6.9%, respectively. Hong Kong only rebounded last Friday. Why has Hong Kong underperformed recently, and how should investors navigate these three markets?

**Why Hong Kong’s Recent Weakness? Sensitivity to Liquidity and Structural Vulnerabilities** Hong Kong’s underperformance stems from its heightened sensitivity to liquidity shifts and structural biases. As an offshore market, it reacts sharply to funding conditions, which have been strained lately.

1. **Slowing Southbound Flows**: Net inflows via Stock Connect dwindled from a daily average of HK$7 billion to under HK$1 billion, even turning negative recently. New fund regulations emphasizing performance benchmarks may trigger portfolio rebalancing, given mainland funds’ 30.8%港股 allocation versus a 17% benchmark weight. However, active mutual funds now account for just 9.1% of Southbound holdings, limiting systemic impact.

2. **External Liquidity Pressures**: Active foreign outflows (US$460 million from港股/ADRs in three weeks) and a hawkish Fed pause pushed 10-year Treasury yields higher, squeezing港股. Despite December’s 25bp rate cut, revised Fed projections hinted at pauses, lifting long-term yields—a reminder that cuts don’t always mean lower rates.

3. **IPO and Unlock Overhangs**: 2025’s HK$260 billion IPO pipeline (global leader) and December’s HK$120 billion unlock pressure added supply-side drags.

**Structural Pitfalls: Tech and Consumer Dependence** 港股 lacks cyclical and hardware-tech buffers, leaving it exposed to: - **Tech**: Dominated by internet platforms (AI applications), it missed the hardware rally seen in A-shares (chips, computing). AI泡沫 fears and US stock volatility further pressured the sector. - **Consumer**: Weak domestic demand and stagnant income growth hurt discretionary spending, while new消费 themes faltered. - **Credit Cycle Slowdown**: China’s private credit pulse weakened post-Q3, dragging港股’s macro-sensitive sectors.

**Historical Outperformance Drivers: Liquidity, Fundamentals, and Themes** 港股 typically leads during: - **Liquidity Surges**: Southbound inflows or Fed easing (e.g., 2024–2025). - **Earnings Recoveries**: Aligned with PMI rebounds (e.g., 2022–2023). - **Structural Plays**: E.g., internet re-ratings (2022), dividends (2024), or AI轮动 (2025).

**2026 Outlook: Navigating Divergences** 1. **Liquidity**: US easing may aid港股, but sustained outperformance requires both US and China investors to see limited local opportunities. 2. **Fundamentals**: US profit growth (12–14%) outpaces A-shares (4–5%) and港股 (3%), with China’s credit cycle stalling. 3. **Themes**: - **AI**: Favor A-share hardware (policy-backed) over港股 applications. - **Dividends**:港股’s higher yields (e.g., banks at 6.1% vs. A-shares’ 4.3%) appeal to tax-insensitive investors. - **Cyclicals**: Watch for US fiscal stimulus beneficiaries (A-share heavy) in Q1. - **Consumer**: Avoid due to weak catalysts.

**Bottom Line**: Hedge with港股 dividends and A-share AI hardware; trade cyclicals if US stimulus materializes. Consumer remains unattractive.
