ExxonMobil Corporation’s common stock trades under the ticker symbol XOM.
XOM is the New York Stock Exchange symbol used for ExxonMobil’s publicly traded common shares. The company is one of the world’s largest integrated energy businesses, with operations spanning oil and natural-gas exploration, production, refining, chemicals, fuels, and related products.
The ticker became especially recognizable after Exxon and Mobil merged in 1999. Exxon itself had been created in 1972 when Standard Oil of New Jersey adopted the name Exxon, while Mobil descended from the Standard Oil company of New York. The combined company kept the ExxonMobil corporate name but uses the concise XOM symbol in stock markets.
A common source of confusion is the company’s many brands and subsidiaries. Esso, Mobil, Imperial Oil, and XTO Energy are associated with ExxonMobil, but they are not alternate ticker symbols for ExxonMobil’s common stock. “XOM” is the canonical answer when a quiz asks for ExxonMobil’s stock symbol. The question’s plural wording is slightly loose, but it does not make the stored answer wrong.
