thats one of the areas where quants squeeze edge the other is more boring where they are essentially "market neutral" and they try to figure out how to make a few cents everyday knowing the downside is a global financial crisis.

their edge is basically political so that they get a bail out and thats what the quants will never see in their models.

not to get cynical further, just do what the GP says, buy index or figure out what the biggest movers are and buy those for more exposure
