Stock symbol

A stock symbol or ticker symbol is a unique shorthand code used to identify shares of a publicly-traded corporation on a stock market.

A stock symbol may either be comprised of letters, numbers or a combination of both.

U.S stock symbol history

In the United States, modern letter-only ticker symbols were developed by Standard and Poor's (S&P) to bring a national standard to investing. Previously, a single company could have many different ticker symbols as they varied between the dozens of individual stock markets.

The S&P system was later standardized by the securities industry and modified as years passed.

Currently a glance at a U.S. stock symbol and its appended codes can tell an investor where a stock trades and may give insight to the company's performance.

Interpreting the symbol

For most stock symbols, the letters are simple identifiers. One- or two-letter symbols always trade on the New York Stock Exchange (NYSE), three letter codes may trade on either the NYSE or American Stock Exchange (AMEX), Four- and five-letter codes trade on the Nasdaq, although five-letter ticker symbols are usually a special class of stock. For example, the ticker symbols of mutual funds must be five letters long and end in "X".

Influence

Sometimes the stock symbol has become more recognizable than a company's real name. For instance, more people may know the Minnesota Mining and Manufacturing Company by the way its three-letter ticker ("MMM") is pronounced on Wall Street, "3M." International Business Machines officially changed its corporate name to "IBM" to match its ticker symbol.
