Yes, of course. There are entire funds devoted to that. It's not really for risk analysis, however; I'm aware of reverse engineering strategy groups for statistical arbitrage and high-freq. trading as well as to play games with index funds (the index funds don't actually buy and hold the entire index; they dynamically manage a smaller representative subset of the index. If too many companies are following similar strats to reproduce the index and somebody can figure this out then there is money to be made) ...There's one black-box fund run by some physicists in London (?) that I think booked 16 billion in 2007 based off of index fund games. Can't remember their name
Also, thank God somebody's overturned State Street. That was a ridiculous decision...
