Google Finance was a website launched on March 21, 2006, by Google. The service featured business and enterprise headlines for many corporations including their financial decisions and major news events. Stock information was available, as were Adobe Flash-based stock price charts which contained marks for major news events and corporate actions. The site also aggregated Google News and Google Blog Search articles about each corporation, though links were not screened and often deemed untrustworthy. Google added advertising to its finance page on November 18, 2008. Google launched a revamped version of their finance site on December 12, 2006, featuring a new homepage design which lets users see currency information, sector performance for the United States market and a listing of top market movers along with the relevant and important news of the day. A top movers section was also added, based on popularity determined by Google Trends. The upgrade also featured charts containing up to 40 years of data for U.S. stocks, and richer portfolio options. Another update brought real-time ticker updates for stocks to the site, as both NASDAQ and the New York Stock Exchange partnered with Google in June 2008. It has not undergone any major upgrades since 2008 and the Google Finance Blog was closed in August 2012. Enquiries and bug reports are not responded to or acted upon so it is presumed to be a discontinued service. On September 22, 2017, Google confirmed that the website is under renovation and the portfolios feature won't be available after mid-November 2017.

However, Google does have another finance page in its search engine, which has a different set of features, including "Recently searched", "You may be interested in", and "Top stories".
In early 2018, a notice appeared on the Google Finance homepage, saying "Google Finance has been renovated." The notice went on to say that "you’ll be able to add stocks from your portfolio to the new Google Finance" and that "[y]ou can also download your full portfolio in csv format, which can be imported into other portfolio services during the transition period." It confirmed that the portfolio feature was to be removed.
