Crowdsourcing, the collective wisdom of the crowds, has been show to have strong correlation to future results specifically in sporting events and election polling. Here's how Tradestreaming addresses crowdsourcing. Given the fact that academia stuck to its guns for SO long with the Efficient Market Hypothesis (that all information is embedded currently into a stock prices, making it really hard to 'beat' the markets), we're just seeing relatively new research that is open to crowdsourcing investment ideas and some that finds that there is MAJOR outperformance. For example, check out the Harvard Kennedy School's "The CAPS Prediction System and Stock Market Returns" paper that studied results of the Motley Fool's crowdsourcing CAPS platform. Specifically, the paper looked at the difference in returns between the most highly rated stocks and the lowest rated stocks. The paper found huge double-digit outperformance (18%).
