On May 21, PetroChina (00857.HK) fell 3.12% in regular trading, trading at HK$11.07/share, with trading volume of HK$323 million.

On the news front, market capital has been persistently rotating into AI and technology sectors, leaving energy stocks sidelined. The three major Chinese oil companies have come under broad selling pressure as funds shift toward higher-growth segments. While CLSA recently named PetroChina as its sector top pick, noting that Q1 earnings had not yet fully reflected the positive impact of higher oil prices, short-term capital flow preferences continue to dominate price action.

Within the Integrated Oil & Gas sector where PetroChina belongs, internal divergence is evident. Sinopec Corp rose 0.67%, contrasting sharply with PetroChina's decline.
