China’s Tech Rout Deepens as Banks Hit $1.4 Trillion Milestone

China’s Tech Rout Deepens as Banks Hit $1.4 Trillion Milestone

TREE NEWS reports: China’s A-share market witnessed a sharp divergence on October 29, with growth-oriented indices plunging over 4% while the banking sector surged to a historic high. The ChiNext index, heavily weighted toward technology and healthcare, closed down 4.45%, and the STAR 50 index fell 4%. The selloff was concentrated in AI hardware and semiconductor stocks, triggered by disappointing earnings from global tech giants and a key domestic supplier. In stark contrast, the ‘Big Four’ state-owned banks—ICBC, China Construction Bank, Agricultural Bank of China, and Bank of China—saw their combined A+H share market capitalization exceed 10 trillion yuan ($1.4 trillion) for the first time, with ICBC and CCB both hitting record highs.

Market Implications

Equities: A Rotation from Growth to Value

The A-share market is undergoing a pronounced style rotation. The selloff in AI hardware names—optical modules, PCBs, and storage chips—was triggered by a trifecta of negative catalysts: Tianfu Communication’s Q3 net profit missed consensus expectations, Google’s Q3 earnings disappointed and raised fears of slowing cloud capex, and Samsung Electronics’ chip division reported weaker-than-expected operating profit. Tianfu Communication hit the 20% daily limit down, closing down 19.77%, while peers like Eoptolink and Zhongji Innolight fell 11% and 8.5%, respectively. The tech-heavy ChiNext and STAR 50 indices bore the brunt, while the Shanghai Composite fell a more modest 0.82%, cushioned by gains in banks, coal, and oil.

Hong Kong mirrored the tech weakness, with the Hang Seng Tech Index dropping 2.84%. AI-related names like Zhongji Innolight and Robotechnik plunged 10% and 18%, respectively. The broader Hang Seng Index fell 0.59%, as strength in banks and energy stocks partially offset tech losses.

Bonds: Safe-Haven Demand

Chinese government bond futures rallied across the curve, with the 10-year contract up 0.11% and the 30-year up 0.09%. The move reflects risk-off sentiment and expectations of continued monetary easing as growth concerns persist.

Commodities: Mixed Signals

Commodity futures were mixed. Energy and industrial metals rose, with fuel oil up 2.13% and iron ore up 2.40%, while lithium carbonate plunged 8.40% on oversupply concerns. Precious metals fell, with palladium down 3.50%.

Currencies and Crypto

The yuan likely faced mild depreciation pressure amid the equity selloff, though no major moves were reported. Cryptocurrencies showed no direct reaction, as the news is China-specific and does not alter the global crypto macro picture.

Why This Matters for Investors

The divergence between banks and tech is a clear signal of investor preference for safety and yield in a weak macroeconomic environment. The banking sector’s rally is underpinned by three factors: a stabilization in net interest margins (NIM), with Q2 2026 NIM rising 1 basis point quarter-over-quarter—the first increase since 2022; a wave of interim dividends totaling over 260 billion yuan from 21 listed banks; and rating upgrades from Fitch, which raised the viability ratings of six state-owned banks. Passive fund inflows have also supported the sector, with index ETFs seeing 15.76 billion yuan of net inflows in the past month.

Meanwhile, the tech selloff reflects a valuation reset rather than a fundamental collapse. Tianfu Communication’s inventory rose 178.65% year-to-date, and contract liabilities increased 128.14%, indicating strong demand and strategic stockpiling. The market’s reaction is a classic ‘expectation gap’ selloff, exacerbated by external shocks from Google and Samsung. Investors should watch whether global cloud capex guidance stabilizes and whether domestic AI hardware orders remain robust.

The commercial aerospace sector bucked the trend, with China Satellite hitting the daily limit, driven by Shanghai’s new satellite internet action plan targeting 80 billion yuan in core industry scale by 2030 and FCC approval for SpaceX’s direct-to-cell satellites. This highlights policy-driven opportunities in strategic emerging industries.

Key Takeaways

• Style rotation is underway: Funds are moving from high-volatility growth stocks to low-volatility, high-dividend blue chips like banks.
• Bank rally has legs: NIM stabilization, attractive dividends, and rating upgrades support further upside, especially as Q4 historically favors bank stocks.
• Tech selloff may be overdone: The drop is driven by sentiment and expectation gaps, not deteriorating fundamentals; watch for stabilization signals.
• Policy catalysts matter: The commercial aerospace sector’s rally shows the market’s sensitivity to government support.
• Global tech earnings are a swing factor: Disappointments from Google and Samsung have outsized effects on China’s AI supply chain.
