Investors can find a company's ticker symbol by using the search functionality on sites such as MarketWatch, Yahoo Finance and Nasdaq. MarketWatch offers a simple search by company name, while Yahoo Finance and Nasdaq allow searches by symbol or company name.
One advantage of searching for ticker symbols on MarketWatch is the site's international functionality. The site allows searching symbols on stock exchanges in 15 different countries.
An investor who knows a company's name but not its home country can search Google Finance, which looks through all the countries in its database by default. However, this approach results in the search engine typically returning more than one result when users input a ticker symbol to search for a company name.
