Tech Growth Stocks Retreat Sharply as Liquidity Drains Ahead of Holiday
TREE NEWS reports: Chinese equities opened lower on September 28, with the tech-heavy ChiNext Index tumbling more than 4.3% and the Shenzhen Component dropping over 3.3%, while the Shanghai Composite fell nearly 1.7% toward the 3,800 level. The selloff was concentrated in computing-power hardware names — optical communications, optical modules, circuit boards, copper-clad laminates, optical switches, and fiberglass — alongside semiconductors, non-ferrous metals, and fine chemicals. More than 4,800 individual stocks declined, with combined morning turnover reaching roughly 1.17 trillion yuan, up nearly 100 billion yuan from the prior session.
What Triggered the Selloff
Two forces drove the retreat. First, pre-holiday liquidity withdrawal ahead of the National Day Golden Week holiday prompted funds to lock in gains on high-flying technology names that had rallied aggressively through September. Second, a valuation reset in crowded AI-hardware trades — particularly CPO (co-packaged optics) and PCB (printed circuit boards) — triggered cascading losses. “Yi Zhong Tian” — the collective shorthand for optical-module leaders Zhongji Innolight, Eoptolink, and TFC Optical — all fell more than 6%, with Zhongji Innolight dropping over 9%. Hengtong Optic-Electric and Fenghuo Communications hit the 10% daily limit down. Among STAR 50 heavyweights, Cambricon fell 5.93%, Yuanjie Technology 7.15%, VeriSilicon 7.30%, and Hua Hong Semiconductor 5.06%.
Hong Kong Diverges, AI Model Names Under Pressure
Hong Kong stocks showed a split picture. The Hang Seng Index briefly rose more than 1% before paring gains to around +0.64%, while the Hang Seng Tech Index opened higher then turned negative, down 0.54%. Major internet names were mixed — NetEase gained over 4%, Lenovo fell over 4% — but AI large-model names came under heavy pressure, with MINIMAX dropping more than 9%. Optical-module concept stocks in Hong Kong, including Zhongji Innolight and Cambridge Technology, led declines.
Precious Metals and Commodities Slump
Gold and silver prices tumbled. London spot gold broke below $4,200/oz, down over 2%, while spot silver briefly lost $62/oz for the first time since August 7, falling 3.5%. Shandong Gold hit the daily limit down after announcing it would cut its 2026 production target from “no less than 49 tonnes” to 36–38 tonnes, with full-year net profit attributable to shareholders expected to decline. Adding pressure, Federal Reserve officials delivered a barrage of hawkish signals, pushing market-implied odds of an October rate hike to roughly 64% and sending 10-year Treasury yields to their highest since 2007. Domestic commodity futures were broadly lower — lithium carbonate fell 4.15%, silver 4.09%, hogs 3.17%, coking coal 2.64%, and glass 2.18% — while container shipping futures rose 5.11% and fuel oil gained 3.22%.
Defensive Rotation: Banks, Power, Real Estate
Capital rotated into defensive sectors. Banks rallied, with Agricultural Bank of China, Postal Savings Bank, and Shanghai Pudong Development Bank each up over 1%. Power stocks were active — Zhejiang Xinneng hit the limit up — catalyzed by National Energy Administration data showing installed generation capacity reached 4.103 billion kilowatts through August, up 11.1% year-on-year, with solar up 16.3% and wind up 19.6%. Real estate also advanced, with Shenzhen Property A hitting the limit up. Government bond futures fell across the curve, with the 30-year contract down 0.12%.
Key Takeaways for Investors
- Holiday liquidity dynamics matter: Pre-Golden Week positioning often amplifies volatility in crowded, high-momentum trades. Expect similar patterns around major Chinese holidays.
- AI hardware valuations are stretched: The sharp unwind in CPO, PCB, and optical modules signals that positioning, not fundamentals, drove recent gains. A genuine earnings-driven reset may create opportunities.
- Gold’s pullback is macro-driven: Hawkish Fed repricing and rising real yields are pressuring precious metals short-term, though medium-term structural demand remains intact.
- Defensive rotation is underway: Banks and power offer relative safety as growth unwinds, supported by improving fundamentals and policy tailwinds.
- Watch the Fed: With October hike odds at 64% and 10-year yields at multi-decade highs, global risk assets face a tightening liquidity backdrop.
