Definition
A Stock Symbol is a unique series of letters assigned to a publicly-traded company for the purpose of security identification on a stock exchange. These symbols are used by investors and market participants to place orders and track company performance in the financial markets.
Detailed Explanation
Stock symbols are essential for the trading process, serving as shorthand to signify a particular stock or company. Most symbols use one to four letters, although there are exceptions. For instance, companies listed on the New York Stock Exchange (NYSE) typically have symbols with up to three letters (e.g., IBM for International Business Machines), while NASDAQ-listed companies generally use four letters (e.g., MSFT for Microsoft Corporation).

- Apple Inc. (AAPL): The stock symbol for Apple Inc. on NASDAQ.
- Alphabet Inc. (GOOGL): The Class A shares of Alphabet Inc., listed on NASDAQ.
- General Electric (GE): The stock symbol for General Electric on the NYSE.
