On May 27, PetroChina (00857.HK) fell 3.02% in regular trading, trading at HK$10.59/share, with trading volume of HK$375 million.

On the news front, positive signals from US-Iran negotiations triggered a sharp decline in international oil prices, directly weighing on petroleum stocks. Reports indicate the US and Iran have reached a framework for a memorandum of understanding, including a 60-day ceasefire extension during which the Strait of Hormuz would be demined and reopened. Brent crude fell 7.02% to $96.14/barrel, while WTI crude dropped 6.52% to $90.30/barrel, as geopolitical risk premiums rapidly dissipated.

Additionally, market capital continues rotating into AI and technology sectors, leaving energy stocks sidelined. Within the Integrated Oil and Gas sector, Sinopec Corp fell 2.26%, reflecting broad sector weakness. The strait carries approximately 20% of global oil and gas supply, and its potential reopening has fundamentally altered short-term market sentiment toward upstream oil producers.
