Thanks Local, what would be the minimum composition of the open interest for the funds roll to have a significant effect on spreads ? Do they have an effect when non-commercial net long position is for example 40% of OI?
I don't know that you can quantify a figure like that, but certainly if spec length is 40% of the open interest it should have a significant impact on the spread. Further to a scenario where specs make up a significant % of length, you have to ask yourself why, or more importantly why are end-users not making up a larger percentage of longs. It may be that the excessively wide spreads make the contract less valuable for end users in terms of a hedge. That is, the cost of rolling longs is greater than the price protection that the contract offers as a hedge. Look at the wheat contract, price goes up, comes down, cost of rolling approaching $2.00/year, really poor hedge for the end user. I have traded contract where teh long is maintained and rolled for years, but after losing enough money the long finally loses enough money and liquidates. That is something I am watching for in the wheat contract,don't know when it will happen but eventually index funds will throw in the towel and liquidate. They put their pants on the same as you and I, eventually they will give up, may not be for years but when it happens you will be able to recognize it. It happened with Jim Rogers after about 5 years. So following the open interest is like following the bouncing ball, it tells a story. Crude is another example.
