If you use Google Finance , you will probably be interested in some new features that have recently been presented in the official blog. Although Google Finance is still not as convenient as Yahoo Finance at the moment, it is getting better with every update. Here is a list of changes:
Price History: View and save data on prices (at the end of the day) for stocks of any American and Canadian companies;
Portfolio: You can download the latest data for all stocks in your portfolio;
News: RSS feeds of the latest financial news;
In Google News, there are links to stock quotes of companies.
There was an integration between Google Finance and Google Calendar - now everything is monitored by Google and conveniently notifies you of news and events.
