                  I am also interested to look at the double short of fas_faz. I did 100 simulations. Each simulation is based on random day to day percent change of IYF (DOW financials) between -10% and 10%. At the time I do simulation, IYF = 34.76, FAZ = 17.18, FAS = 6.48. I assume initial investment of faz_value = 100000, fas_value = 100000; We look for the results after 500 trading days in each simulation. 
Among 100 simulations, only 4 times (huge finacial bull markets) double shorts will lose money. 
it does not seem like a bad idea to short both given the fact that a huge financial bull market is not in order for a while to come.
