Google Finance, which is being launched in the US today, will provide corporate news, information and graphs and allow users to search blogs for the opinions of other private investors. It could be extended to Europe as soon as it has proved its worth.
The project seeks to shake up the online finance information market dominated by sites such as Yahoo! and MSN.
The site identifies financial stories within Google News, the company's existing news search sites, and features links to other sites for financial and company news, including those of Reuters, Morningstar and Revere Data.
One of the more novel features of the site is that it gives the user the ability to view financial news alongside historical price charges over various time frames.
While Yahoo! was the first of the major internet sites to incorporate blogging alongside news in its Yahoo! news site, Google Finance is the first to run blogs alongside financial news.
Katie Jacobs Stanton, product manager for Google Finance, said: "We are going to provide quick, easy access to financial information by taking complex financial data and making it more digestible."
The launch is the latest in a string of developments at Google, which is using its position as the world's most popular search engine to expand into new areas.
