Want to outsmart Wall Street? Join Estimize.

The concept is simple: Estimize crowdsources earnings estimates from over 24,000 people. The vast majority of the time, the wisdom of the big crowd on Estimize actually does a better job of predicting earnings than the Wall Street pros.

If you're someone who looks at a company's fundamentals before you buy or sell a stock, then you should strongly consider joining Estimize.

It's free to sign up. Estimize tracks 2,100 companies and even crowdsources economic estimates now too. For popular stocks and the jobs report, several hundred people usually submit forecasts.

You don't have to make estimates, but the platform is more useful to you if you do. Once you make an estimate (for example, on Apple stock), you can see how your forecast stacks up to other people's. There's even a ranking of the most accurate predictors.

"It still holds true that, on average, non-professionals are more accurate," says Leigh Drogen, CEO and founder of Estimize.

Investors from anywhere in the world can participate. Estimize also has a blog with daily stock ideas and insights.
