What is a ticker?

Tickers, often referred to as ticker symbols, are unique combinations of letters assigned to publicly traded companies and financial instruments on stock exchanges. They provide a shorthand way for investors and traders to identify and reference specific stocks, bonds, or other securities. For example, 'AAPL' is the ticker for Apple Inc. Ticker symbols are essential for tracking market activity and making trades efficiently. The format and length of a ticker can vary depending on the exchange and the type of security.
