Quote from Steven.Davis:
The CFTC COT data show that sometimes there are groups which take a definite directional position. When extreme, these can be leading indicators.
Well the problem with the COT right now is that the open interest is pretty low on a lot of it so it doesn't really matter as much, however like you probably know then the commercial group is pretty massively (and suddenly) short equities across all indices (and commodities show the same overall pictures by the way, commercials are pretty much short everything but natural gas and a few others).
