MSFT is the stock-market symbol for Microsoft on the Nasdaq.
A ticker symbol is a short code used by an exchange and financial-data services to identify a publicly traded security. Microsoft’s common stock trades under MSFT, a four-letter symbol that has been associated with the company for decades.
Microsoft is one of the world’s largest companies by market capitalization. Its major businesses include Windows, Microsoft 365, Azure cloud computing, Xbox, LinkedIn, and enterprise software. Because its share price changes throughout each trading session, Microsoft’s market capitalization also changes continuously.
Ticker symbols are not the same as company names, stock exchanges, or legal identifiers. For example, MSFT identifies Microsoft’s listed common stock, while Nasdaq identifies the exchange on which that stock trades. Similar-looking codes can therefore create confusion in financial searches.
