Collective Money Management

Location: Starlight Roof Level:

The stock market has long been seen as the antithesis of sharing. There is only so much money to be made, so why would you tell anyone else your good ideas? It is, to that way of thinking, a zero-sum game.

How, then, do we explain the rise of a host of new web-based services predicated on sharing information about trades and stocks? Are they wrong? Is the market? We’ll talk about it with representatives from some of the hottest social stock-picking sites out there, and we’ll try to figure what, if anything, there is for professional investors to learn about the future.
