Here's my "Tom Clancy movie plot" evil fund. Someone starts a fund that's actually based on figuring out the portfolios of Senators, moderately high net worth congresspersons and other Washington insiders. However, instead of duplicating the entire portfolios of the whole populace, you first filter for IQ, an age range where people are starting to be very well connected but still making their fortunes, and develop another filter based on a quantitative proxy for riskiness of each investment.

This is what the fund will really be based on, though there will be a fig leaf fictional method advertised. The purpose of this is to piggyback on the (technically-not) insider trading such people will manage to do while still staying within the letter of the law. (Somehow, the collective portfolios of US representatives manage to greatly outperform the stock market indexes.)
