In an effort to stay hot on Yahoo!'s tail, Google has updated Google Finance
. It's only been six months in the running, and now its time for a change. In this update, Google has added data and charts for up to 40 years of US stocks. A new homepage design lets users see currency and sector information instantly, as well as a listing of top movers. Registered users on the site have the ability to build portfolios and track stocks and companies. Users can also upload information from other online portfolios into their Google Finance portfolio. The new beta design launched on Tuesday. Don't forget to also add your Google Finance portfolio to your start page
So what do you think? Is it a Yahoo! Finance killer yet?
