HK Stocks Midday: Hang Seng Up 0.12%, Gold Stocks Lead Gains, Zhida Tech Surges Over 30%
nashnova research
The Hang Seng Index edged up 0.12% to 24,697 at midday on September 16, led by gold and optical-communications stocks, while CATL fell 3.49% as automakers reshuffle their battery supply chains.
How much did the market move, and where did the money go?
The HSI added roughly 30 points to 24,697; the Hang Seng Tech Index rose 0.87%, outpacing the broader market.
Morning turnover hit HK$95.6 billion — liquidity was ample, but flows were selective, not broad-based.
This means → today's session is not a blanket rally; capital concentrated on two themes: gold and optical communications.
Why did gold stocks suddenly surge?
Spot gold climbed back above US$4,300 per ounce, directly lifting the sector.
Lingbao Gold (03330) rose 6.3%; Chifeng Gold (06693) gained 6%, leading the pack.
This means → the market is positioning ahead of the Fed's rate decision, buying gold as a hedge. In plain terms = when the rate path is unclear, investors grab gold as "insurance."
Why did optical-communications stocks rally together?
Trump joined Nvidia's Jensen Huang in publicly dismissing the "AI doomsday" narrative; brokers read this as raising the certainty floor for AI capex.
Haiguang Xinzheng (01191) and Cambridge Technology (06166) both jumped 13%; YOFC (06869) added 6.7%.
This means → optical communications is the "plumbing" of AI compute — the more certain the demand, the faster the plumbing companies rally.
Which stocks posted the biggest gains, and why?
Zhida Tech (02650) surged over 30% — its German factory is now operational and it showcased at a Brazil expo, boosting overseas revenue expectations.
Yunying Valley Tech (03310) jumped over 22% — it announced two new business lines in optical interconnect and UCIe IP, a standard that lets different chips "talk" to each other.
Luyuan Group (02451) rose over 14% — first-half electric-motorcycle sales topped 400,000 units, ranking first nationwide.
Tianyu Semiconductor (02658) gained nearly 14% again — it has been buying back shares throughout the month, and its 8-inch epitaxial-wafer capacity ramp is on track.
Why did CATL buck the trend and fall?
CATL (03750) dropped 3.49% in the morning session, one of the few heavyweight decliners.
Leading EV makers are collectively reshuffling their battery supply chains, shifting from reliance on a single dominant supplier toward locking in more second-tier battery firms.
This reflects a loosening of the battery industry's power structure — automakers want to diversify risk, and CALB (03931) rising 5.78% is the flip side of that same trend.
In plain terms = CATL's orders may not shrink outright, but its near-monopoly is being diluted, and the market is still watching how far the shift goes.
