A stock ticker symbol is a unique series of letters representing a particular publicly traded company on a stock exchange. Ticker symbols are used for quick and easy identification of a company's stock in financial markets. For example, "AAPL" is the ticker symbol for Apple Inc. and "MSFT" is the ticker symbol for Microsoft Corporation.
A stock ticker symbol is typically a combination of letters, sometimes accompanied by numbers, and is used to identify a specific company's stock on an exchange. Ticker symbols are commonly used in financial news, stock quotes, and trading platforms to refer to a particular company's stock.
