My goal is to find out the most efficient way to express a view on skew. Say if I expect the skew to get steeper from 5 vol points to 6 vol points, not the overall shift of vol surface. These two things (steepening of skew and the elevation of vol) of course are correlated (correlation at about 0.4).
Since folks bring it up, here is my thought about trading both skew and vol with options simultaneously:
a. if you expect vol level to go up, you buy strangle (1 30 detla OTM put + 1 30 detla OTM call)
b. If you expect skew to get steeper at the same time, you long 5 30 detla put short 5 30 detla call and long 300 underlying (to zero out delta) trade
So if you combine two a and b, the overall positions become
c. long 6 30 delta OTM put + short 4 30 delta OTM call + long 300 shares of underlying.
My thought is that there is a vol trade and there is a skew trade. They are correlated but not the same thing. You can trade them both at the same time.
I apologize that that the post is a little too long.
