Google has enhanced Google Finance in a bid to make the service more competitive in the financial website market.

Google has improved the site's charts, which now can display up to 40 years of historical data for US stocks, up from five years previously. The company has also added a "top mover" module to the site's home page that spotlights companies with the biggest changes in stock price, market capitalisation and trading volume, as well as those that have been searched for the most in Google's search engine. Google also increased the ways to customise and organise portfolios, and made it possible to import portfolios from other websites.

It remains to be seen how much these latest improvements will help boost the site's popularity. For the week ending 9 December, Google Finance ranked 31st in Hitwise's Stocks and Shares category of business and finance sites with a measly 0.48 percent of visitors.

Yahoo Finance ranked first with almost 24 percent of all visits, while Microsoft's MSN Money nabbed a distant second place with 8.4 percent. Google Finance came in 23rd place in Hitwise's Business Information category with 0.70 percent of all visits. Yahoo ranked first with almost 35 percent of visits, while MSN Money was second with 12.4 percent.
