China's three major state-owned oil companies—PetroChina (CNPC), Sinopec, and CNOOC—issued announcements on abnormal stock price fluctuations on the evening of March 3. The notices indicated that the cumulative deviation in the closing prices of PetroChina's A-shares and CNOOC's shares over three consecutive trading days (February 27, March 2, and March 3) had each exceeded 20%. The companies attributed the unusual volatility to the impact of geopolitical tensions on the international crude oil market. This move represents a standard procedure for listed companies to alert the market to risks following significant price swings, highlighting the direct impact recent geopolitical factors have had on the energy sector, particularly on the stock prices of fossil fuel-related enterprises.
