Ah - voodoo indeed. No way that kind of return is possible for an unlimited amount of capital ... so cap your input and maximize return ... then roll out the marketing machine. Brilliant!  
  
 No small feat to gain 60% average even with 10M. With more data coming online and “freely” available how much longer can a pure quant strategy survive... Eventually dont market forces eliminate their advantage?

They do eventually go away but they are exploiting a massive headstart.
