What Is Ticker Symbol?
A ticker symbol (or stock symbol) is a unique series of letters assigned to a publicly traded security for identification purposes on stock exchanges and trading platforms. NYSE-listed companies traditionally use 1-3 letter symbols (e.g., F for Ford, GE for General Electric, JPM for JPMorgan), while NASDAQ-listed companies typically use 4-5 letters (e.g., AAPL for Apple, MSFT for Microsoft, AMZN for Amazon). Ticker symbols were originally created to simplify communication via telegraph and ticker tape machines. Some companies carefully select symbols that reinforce their brand identity — Southwest Airlines uses LUV (referencing its Dallas Love Field hub), Harley-Davidson uses HOG, and Olympic Steel uses ZEUS. ETFs also have ticker symbols (SPY for S&P 500, QQQ for NASDAQ-100). When a company changes its name or merges, the ticker symbol may change. Searching for a company's ticker symbol is usually the first step in researching or trading a stock.
