(plural stock symbols)
- Short form of stock ticker symbol.
A unique identifying symbol assigned to publicly traded companies that makes it easy to identify the company on stock tickers and online services. The symbol also prevents confusion when entering trade orders into an electronic trading system. Typically, New York Stock Exchange companies have two- or three-letter symbols and NASDAQ companies have four- or five-letter symbols. The fifth letter typically is added if the company is traded on the over-the-counter market.
