Hong Kong Stocks Open Lower: Hang Seng Index Falls 0.94%, Weichai Power Surges Over 10%, Tech Stocks Broadly Decline
nashnova research
After the Fed's surprise 25-basis-point hike, Hong Kong equities opened broadly lower on September 17, with the Hang Seng at 24,480 — down nearly 1%; Weichai Power's 10%+ rally stood out as tech, gold and oil names fell across the board.
Why did the Fed hike, and how did Hong Kong react?
The Fed raised its target rate by 25 basis points to 3.75%–4% overnight — the first hike since July 2023, passed unanimously by all 12 FOMC members.
This means → the market's "pause" bet was wrong, and money shifted to safety immediately.
The fallout: all three U.S. indexes fell, the dollar index climbed above 100, and the 10-year Treasury yield broke through 5% — Hong Kong's weak open tracks that external shock directly.
How far did the four benchmark indexes drop?
The Hang Seng Index opened down 0.94% at 24,480.57.
The Hang Seng Tech Index fell 1.03% to 4,281.03; the H-share index lost 0.97%; the Red Chip index dropped 0.96%.
In plain terms = large caps, tech and state-enterprise names all sold off at the open — no index was spared.
Why did Weichai Power buck the trend with a 10%+ gain?
Weichai Power (02338) surged 10.01% at the open, leading all HSI constituents.
Goldman Sachs reiterated a "buy" rating the same day, citing the company's AI data-center power-generation business outlook.
This means → even in a broad sell-off, stocks backed by a clear institutional call and a fresh growth story can still attract capital. Shenzhou International (02313), up 1.97%, was another counter-trend name.
How much did tech and resource stocks fall?
Internet names slid: Tencent (00700) fell 1.66%; Alibaba (09988) dropped 1.13%.
Gold stocks weakened: Zijin Mining (02899) lost 1.51%; Shandong Gold (01787) fell 2.44%.
Oil stocks came under pressure: CNOOC (00883) dropped 1.56%, Sinopec (00386) fell 1.41%, PetroChina (00857) slipped 1.02%.
Were there any bright spots inside tech?
Optical-communication names edged higher: YOFC (06869) rose 1.13%; ZTE (00763) gained 0.35%.
Within the Hang Seng Tech Index, Zhipu (02513) climbed 2.78%, MINIMAX-W (00100) added 1.68%, and Tianshu Zhixin (09903) rose 1.19%.
Zhipu disclosed a day earlier that its full-business ARR (annual recurring revenue) had reached $1.8 billion, and raised its year-end ARR guidance from $2.4 billion to $3 billion — this reflects AI companies' fundamentals decoupling from broader market sentiment.
What to watch next?
The key variable is whether the 10-year U.S. Treasury yield stabilizes — it directly anchors risk-asset pricing worldwide.
In plain terms = if Treasury yields keep climbing, pressure on Hong Kong stays; if they level off or pull back, the market gets room to breathe.
Whether today's counter-trend names (Weichai, Zhipu) sustain volume through the session is also a signal worth tracking.
