The ticker symbol for Apple Inc. on Nasdaq is AAPL.
A ticker symbol is a short identifier used by a stock exchange and financial data services to represent a publicly traded security. In Apple's case, the four-letter symbol AAPL identifies the company's common stock on the Nasdaq Stock Market. It is not the company's legal name or a product abbreviation.
Apple went public on December 12, 1980, in one of the most notable technology IPOs of its era. The company sold millions of shares in the offering, and its stock has since undergone multiple splits. Those splits changed the share price and the number of shares outstanding, but they did not change the ticker symbol.
AAPL is often mistyped as APPL, AAP, or APL. APPL is especially tempting because it resembles the company name, but it is not Apple's Nasdaq symbol. Investors may also see AAPL in market indexes, brokerage apps, financial news, and Apple's investor-relations materials; all refer to the same listed common stock.
