These sites have tools you can trust to help you make better money decisions.
Best Site: Finance.Google.com
Plenty of free sites help you screen stocks by criteria like earnings growth or P/E ratios. But Google's Stock Screen tool makes the process intuitive. Want to see only stocks with P/Es at the low end of the range? A bar chart showing the current distribution of P/Es in the market is built right into the selection tool. Just move a pair of sliders along the chart to focus on the part of the market you want to see.
Coolest feature: For a unique indicator of consumer and market sentiment, check Google Domestic Trends -- it shows you how often Google users searched industry-related keywords. Searches on luxury goods are way down since 2006.
Try this too: Grahaminvestor.com has preset screens based on the value-investing philosophy of Ben Graham. It's run as a hobby by an IT guy who's also a Graham fan.
Google's screener lets you see the whole market as you sort.*
