Quick answer
A ticker symbol is a short abbreviation that identifies a publicly traded security, such as a U.S. common stock, for trading [1]. It is also called a stock symbol [2].
#What does a ticker symbol look like?
Investor.gov explains that U.S. stock tickers run from a single letter up to five letters [1]. Nasdaq's glossary defines a ticker simply as an abbreviation assigned to a security for trading purposes [2]. Funds and ETFs have tickers too, which is how you find them in a brokerage account.
#What can extra letters in a ticker mean?
Sometimes letters are added to signal something about the security. Investor.gov gives one example worth knowing: a "Q" after a ticker signifies that the company is in bankruptcy [1]. If a familiar symbol suddenly shows an extra letter, find out why before trading.
| Identifier | What it is | Where you see it |
|---|---|---|
| Ticker symbol | 1–5 letter trading abbreviation | Quotes, order screens, news |
| CUSIP number | 9-character code identifying the issuer and the type of instrument | Account statements, bond and fund documents |
| Company name | Legal name of the issuer | Filings and official documents |
#How do you read a stock quote line?
Worked example
Reading a quote
A quote screen shows: XYZ 25.40 +0.38. That is the ticker, the last trade price and the change from the previous close.
- Previous close ($25.40 − $0.38)
- $25.02
- Percentage change ($0.38 ÷ $25.02)
- +1.52%
The ticker tells you which security you are looking at; the numbers tell you its latest price and move. Always confirm the company name next to the ticker.
XYZ is a made-up ticker used for illustration.

Frequently asked questions
Can a company change its ticker?
Yes. Tickers can change after a name change, merger or move to a different market. Old news articles may use the previous symbol.
Is a ticker the same in every country?
No. Each exchange has its own symbols, so the same company can have different tickers on different exchanges. Check which exchange a quote comes from.
