Stock symbols, also known as trading symbols, are unique identifiers assigned to publicly traded companies. These symbols, typically composed of one to four letters, are used on securities exchanges to facilitate easy identification and efficient trading of a company’s stock.
Types of Stock Symbols
Common Stock (NYSE and NASDAQ)
- NYSE: Uses one to three-letter symbols. Example: “T” for AT&T.
- NASDAQ: Uses four to five-letter symbols. Example: “AAPL” for Apple Inc.
Preferred Stock
- Often indicated by adding a letter following the common stock symbol. Example: “AIGpA” for AIG’s preferred shares.
Exchange-Traded Funds (ETFs)
- Typically consist of three or four letters. Example: “SPY” for the SPDR S&P 500 ETF.
Special Considerations
Multiple Listings
- Companies listed on different exchanges may have different symbols. Example: “VOD” on NASDAQ and “VOD.L” in London.
Suffixes
- Certain suffixes provide additional information. For example, a “Q” at the end usually signifies bankruptcy proceedings (e.g., “GMQ”).
International Symbols
