As of March 2025, there are over 3,968 companies listed on the NYSE alone. There are currently 13 active stock exchanges in the US. This is why understanding the stock symbols or stock market tickers is important, as they help you identify the company you are investing in.
Stock symbols or ticker symbols are a quick way to describe a company’s stock listing on a stock exchange. However, different stock exchanges follow different structures of stock symbols. In this blog, we will understand what stock symbols are, their use, significance and examples.
What is the Use of Stock Symbols?
Stock symbols, also known as ticker symbols, are short, unique combinations of letters used to identify publicly traded companies on a stock exchange. They were created in the 1800s to streamline the process of hundreds of trades taking place every minute.
In the 1800s, as modern stock exchanges emerged, floor traders communicated the stock price of a traded company by writing or shouting the company’s name. This entire process was challenging and time-consuming. As the number of publicly traded companies continued to rise, it became even more difficult to keep up with the frequently changing prices.
To make the entire process efficient, the names of the publicly traded companies were shortened to one to five alpha symbols. Stock symbols saved time and captured specific stock prices at the right time. Today, all major stock exchanges worldwide use ticker symbols.
History of Ticker Symbols
Edward Calahan, a telegraph operator who worked for the New York Stock Exchange, invented the ticker symbol in 1867. The symbols were able to quickly and accurately transmit stock prices over telegraph lines. Calahan’s ticker symbol represented the company’s name with two letters. The letters had a number at the end that exhibited the number of shares being traded.
The early ticker systems would abbreviate company names to conserve space. The precursor of what would eventually be stock ticker symbols. The abbreviations were initially not standardized and tended to differ by broker or machine.
With the increase in trading volume and the number of listed companies in the early 20th century, exchanges such as the NYSE and later the Nasdaq formalized the practice of assigning a company a unique stock symbol. This aided in simplifying communication in the market.
It also minimized mistakes and made trading effective. The NYSE tended to give 1-3 letters (e.g. F for Ford, KO for Coca-Cola). The first electronic stock market, Nasdaq, opened in 1971, and it chose to differentiate itself with 4-letter symbols (e.g., AAPL for Apple).
Types of Stock Symbols or Tickers
Here are the 3 primary types of stock symbols you must know:
1. Based on Share Voting Class
If the company has more than one class of shares trading in the market, the market uses share voting class symbols to indicate whether the company’s shares have voting rights.
Examples: Alphabet, the parent company of Google, has two classes of shares trading in the Nasdaq stock exchange with stock symbols GOOG and GOOGL. GOOG represents Class C shares and has no voting rights. GOOGL shares are Class A shares. Each share has one vote.
Similarly, Warren Buffet’s company Berkshire Hathaway has two classes of shares trading on the NYSE with stock symbols BRK.
- BRK.A: Class A shares – full voting rights, very high price
- BRK.B: Class B shares – lower voting rights and lower share price
- Both are traded on the NYSE
2. Preferred Shares
Preferred shareholders have the first right to dividends. The company must pay them before common shareholders. However, these shares have limited to no voting rights. If the market lists a. preferred stock, it will have .PR or .P letter as a suffix in its ticker symbol.
3. Stock Ticker Modifiers
Stock ticker modifiers are single letters or combinations of letters that provide additional information about a stock. In the Nasdaq stock exchange, a fifth letter is added to the ticker symbol of the stock. The stock symbol for Acer Therapeutics Inc. is ACER. If the shares have warrants attached, they will add the letter ‘W’ on the last. The result will be ACERW.
Length of the Stock Symbols
A full stock symbol includes both the company’s ticker and the exchange or country where it’s traded. An example is Microsoft, which is listed on Nasdaq as NASDAQ:MSFT or MSFT:US. Another example is British Petroleum, which is listed on the London Stock Exchange as BP:LON or BP:UK.
The length of tickers differs according to exchanges. Nasdaq symbols are normally four to five letters in contrast to other exchanges, such as the NYSE, which mostly uses one to three. The majority of the companies have symbols that are formed on their names, but some prefer creative or memorable tickers-such as Molson Coors, which is traded as TAP.

How To Use a Ticker Symbol?
Ticker symbols consist of one to five letters and are used to identify publicly traded companies on a stock exchange. You can use a ticker symbol in several ways:
- Identifying Securities: Ticker symbols help quickly identify a stock or bond on a stock exchange. For example, MSFT represents Microsoft, and WMT represents Walmart.
- Placing Trades in the Stock Market: To place a trade, you need to use the correct ticker symbol of a stock you want to buy or sell. You should double-check the ticker symbol to avoid errors.
- Research Company Details: Financial websites use ticker symbols to find detailed information about a company. You can find information such as financial statements, press releases, and other updated information.
- Track Market Data: You can use ticker symbols to view real-time market data such as price changes, current stock price, and trading volume.
Why Is It Called a Ticker Symbol?
Stock symbols were originally imprinted on the ticker tape. Ticker tape was a continuous roll of paper produced by telegraph machines that displayed the stock prices. These machines printed a narrow paper tape to create a visual representation of the changing stock price. The name ticker came from the “tick” sound these machines made as they printed the information.
Conclusion
Stock symbols not only provide you with one important piece of information, but also help you find out facts about any company or instrument you are interested in. This is very useful to traders who have limited time to go through thousands of equities listed on the NYSE and Nasdaq.
It is tedious, time-consuming and ineffective to manually check and decide which stocks are going up or down. Instead, traders get significant information on price, liquidity and price change within seconds by merely glancing at a ticker symbol.
