Not exactly. the main strategy that I discussed in original post yields 8-14%. the 2nd (flavor) - using the same edge from where the main strategy comes from - can be used to spike up a return of S&P by ~1%. I used that to illustrate that the edge is not correlated with S&P.
What is the leverage #? What is return % range if it used without margin (just initial margin requirements)? Which leg is shorted most often?
