Quote from dmo:
I know what you mean, but CL is probably not the best example. At the moment, the CL skew is quite even up and down - a true smile of volatility. I love the crude skew because it is very pliable - the call skew can be steep while the put skew is flat, the put skew can be steep while the call skew is flat, etc. That baby moves, unlike the SPX skew which is rigid as a board and never budges.
A better example of what you're looking for is gold, or the grains. Why do those exhibit skews that are the opposite of the SPX skew? My answer is to look for where the emotion is - the excitement and the panic. In stock, it's the downside. In natural resources, it's the upside.
That's really just another way of expressing the same thing Atticus said. Most of the world is long stock so portfolio protection means buying puts. The world is short wheat and soybeans, so portfolio protection means buying calls. You and I are "short wheat" because we're going to consume more bread and pasta in the future than we own today.
Does most of the world panic when stocks go up? Of course not. Does most of the world panic when wheat goes down? No again.
could you pls. explain this a bit more:
"The world is short wheat and soybeans, so portfolio protection means buying calls".
For instance what do you mean by the "world"? From the context, I am understanding that you mean by this the financial world of commodities. If this is the case, is it not true that for each short position, there is a corresponding long position? Thanks.
