When it comes to trading stocks, collecting data and researching companies online can feel a little like scouring a library's shelves for a book whose title you don't know. SpreadsheetPortfolio eliminates the need for a lot of that guesswork—and cuts out the pundits and their dismal track records—in the process.

The tool constantly compiles major data sets from the Internet and runs beefy analytics. An easy-to-read layout displays the DCF intrinsic value and actual price of a stock, along with its market status, risk premium, and maiden name. The result is a kind of digital broker that saves you hours of pouring through chintzy blogs and batting down pop-up ads and delivers pivotal information immediately for potentially sounder investing.
