Quote from Rearden Metal:
So here's a killer idea for a hedge fund that I don't mind giving away for free, because I know I'd never pull off putting something like this together: You get a team of intelligent dudes together to scour the net for anyone who can put out consistently awesome or consistently terrible market calls. (Perma-bulls and perma-bears don't count) With a few thousand man-hours of work, you put together a nice long list of (mostly anonymous) sources, who probably couldn't be trusted on their own, but by allocating just a tiny fraction of AUM to each one, the whole is far more trustworthy than the parts would be alone, kind of like a junk-bond fund or a fund of funds. Then your team constantly monitors these sources, especially looking for correlation between them. New sources are also constantly developed.
I actually think this could work, I really do.
