PetroChina was the first publicly traded business in Asia to reach a US$1 trillion market value.
PetroChina briefly reached a market capitalization of about US$1 trillion on November 5, 2007, during its debut on the Shanghai Stock Exchange. The listing was one of the largest in the history of that exchange and drew intense investor attention.
PetroChina is the publicly listed arm of China National Petroleum Corporation, one of China’s major state-owned energy groups. Its operations include exploration, production, refining, transportation, and marketing of petroleum and natural-gas products.
The milestone was brief because share prices can move sharply after a high-profile listing. It is also distinct from the later US$1 trillion milestones achieved by U.S.-listed technology companies. Currency conversions and the choice of share classes can affect how rankings are reported.
