CNOOC Ltd. (ISIN HK0883013259) traded at HKD 23.94 on the Hong Kong Stock Exchange on September 23, 2026, while its 52-week range stood at HKD 18.42 to HKD 30.98. The stock's market value was HKD 1.13 trillion and reported volume was 104 million shares on the same date.

Oil prices set the market tone

CNOOC shares moved lower as the broader China stock market weakened and oil prices faced renewed pressure. Trading Economics reported on September 23, 2026, that CNOOC lost 0.9 percent among notable decliners, while the wider market also retreated.

The market backdrop matters because CNOOC's earnings remain closely linked to realized oil and gas prices as well as production volumes. A weaker commodity price can pressure revenue and cash generation even when output continues to increase.

First half delivered double digit growth

The latest reported figures provide a stronger operating counterweight. According to Morningstar on August 27, 2026, CNOOC's first-half net profit rose 23 percent year over year, supported by a 24 percent increase in average realized oil prices and 4 percent growth in net oil and gas production.

That comparison is important for investors: profit growth exceeded production growth by 19 percentage points, showing that pricing contributed more to the first-half improvement than volumes alone. The same report states that 2025 net production reached 777.3 million barrels of oil equivalent, with oil accounting for 77.2 percent of the total.

Stock remains below yearly high

The HKD 23.94 quote was HKD 7.04 below the 52-week high of HKD 30.98 and HKD 5.52 above the 52-week low of HKD 18.42, based on the September 23, 2026 market snapshot. The range places the shares closer to the lower end than to the annual peak.

Morningstar's latest market data also show a reported volume of 104 million shares against an average volume of 68 million, or 36 million shares more than the stated average. That turnover gives the daily move more market participation than a thin-volume price change.

HKD 23.94 was the reference price
