It consists of a combination of letters and numbers, making it easy to recognize and reference a specific security. In the United States, stock symbols are typically three to five characters long.
How are Stock Symbols Formed?
Stock symbols are usually created by the exchange on which the security is listed. They follow a specific format, which may vary slightly between exchanges.
