Quote from HFStartup:
Given these conditions and the comments posted, I find my attention being drawn to straddles. To be specific, selling a straddle on the declining index and buying a straddle on the inclining index. I would do this in a ratio, perhaps selling twice as many options as I would buy if needed to produce a net credit. The net short aspect of this strategy (if it exists) would allow me to take advantage of the time decay, provide a method to capitailize from the statistical fact that markets tend to decline faster than they rise, and provide some degree of hedging.
