Hong Kong Stocks Close Lower on August 11: Hang Seng Index Falls 1.1%, Oil Stocks Buck the Trend, Gold Stocks Tumble
Alina Collins
The Hang Seng Index closed down 1.1% at 25,652 on August 11, with the tech index dropping nearly 2%; a US-Iran negotiation breakdown drove oil prices up over 5%, lifting oil stocks, while gold miners tumbled after a hawkish Fed signal.
All three indexes fell — where did the money go?
The Hang Seng Index dropped 1.1% to 25,652.82; the H-share index fell 1.09%; the Hang Seng Tech index fell 1.93%, the steepest decline.
Turnover hit HK$210.9 billion — not thin at all. Money wasn't sitting idle; it was actively rotating.
CICC's read: this rally was driven by "relative appeal" — tech stocks looked expensive and crowded, making Hong Kong look cheap by contrast — not by a genuine earnings upgrade. This means → once valuations and sentiment revert to the mean, upside narrows unless earnings actually improve.
Oil prices jumped 5% in a day — why did oil stocks lead?
CNOOC (00883) rose 3.59%, PetroChina (00857) gained 1.78%, COSL (02883) added 1.51% — the oil sector was the day's strongest group.
The driver was geopolitical risk: US-Iran talks collapsed. Trump demanded war reparations from Iran; Iran said it won't negotiate before Trump's term ends. Brent crude surged over 5%, approaching $90 again.
In plain terms = when the US and Iran clash, markets fear a Middle East supply disruption. Last week the US Strategic Petroleum Reserve fell by 6.1 million barrels to 298.7 million — inventories were already low. Tight supply plus peak summer demand amplified the price swing.
Gold stocks slumped from their highs — what happened?
Spot gold dropped from a morning high of $4,434/oz to below $4,360 in the afternoon. Chifeng Gold fell 6.01%, Zijin Mining fell 5.8%, Shandong Gold fell 4.83%.
The trigger: Cleveland Fed President Beth Hammack said the Fed may need multiple rate hikes to push inflation back to 2%. This means → rates could stay higher for longer, raising the opportunity cost of holding gold. Profit-takers at the highs seized the moment.
Zijin Mining alone dragged the HSI down 20.02 points — almost exactly offsetting CNOOC's 20.01-point contribution. The day's index move was largely a tug-of-war between these two stocks.
Why did innovative pharma and MLCC stocks buck the sell-off?
Innovative pharma: Jacobio (01167) surged 11.53% after a positive profit alert; CStone Pharma (02616) rose 11.32%; Zai Lab (09688) gained 5.28%. Jacobio expects at least RMB 600 million in net profit for the first half — its first-ever profit — mainly from a global licensing deal with AstraZeneca on a pan-KRAS program (a drug target aimed at one of the most common cancer-driving genes).
This reflects a shift in the sector's logic: Zhongtai Securities argues that since 2026, China's innovative pharma has moved from "rally on licensing-deal headlines" to "revenue from actual overseas sales and clinical data delivery." In plain terms = the market is starting to pay for money actually earned, not just for the story.
MLCC — multilayer ceramic capacitors, one of the most basic components in electronics — also ran hot. Sanen Group (06951) rose 9.62%. AI demand is fueling a scramble for passive components; some buyers are paying two to three times normal prices to secure supply from Yageo and Murata. SG Micro (03661) gained 8.09%, boosted by analog-chip giant ADI announcing a price increase across its entire portfolio effective September 13.
Two launch setbacks in two days — how did aerospace stocks react?
LandSpace's Zhuque-3 Y2 rocket, scheduled for August 11, was postponed. On August 10, a Long March 7A carrying the Zhongxing 4B satellite failed; the cause is under investigation. Two negative headlines in 48 hours hit the commercial aerospace sector broadly.
Goldwind Technology fell 7.99%, Junda Technology fell 6.05%, APT Satellite fell 3.98%.
Airline stocks also declined, but for a different reason — surging oil prices raised fuel-cost expectations, pressuring the sector as a whole.
What's next on the radar?
The market's attention now turns to the US July CPI release on the evening of August 12.
This means → the data will directly test whether inflation is actually falling, and shape whether the Fed's next move is another hike or a pause — with direct implications for Hong Kong's valuation framework and capital flows.
