What does the ticker symbol AAPL identify in the U.S. stock market?

In the U.S. stock market, the ticker symbol AAPL identifies Apple Inc.

A ticker symbol is a short code used to identify a publicly traded security on an exchange or quotation system. Apple’s common stock trades under AAPL, while its shares are listed on the Nasdaq stock exchange. Investors use the symbol to find quotes, charts, filings, and trading instructions.

Ticker symbols are not universal across every country or asset class. The same company can have different symbols on different exchanges, and a symbol can change after a company rebrands, merges, or transfers its listing. Symbols can also identify exchange-traded funds, preferred shares, and other securities rather than ordinary common stock.

AAPL identifies the security, but it does not describe Apple’s share price or guarantee that the company is profitable. Investors still need to check the exchange, security type, currency, and current quote before placing an order.
