Is there an ETN of this? http://www.bloomberg.com/apps/news?pid=20601084&sid=awfVOrPDcdfw&refer=stocks
It must be bearish. A new contract tends to be launched after the underlying bullish trend of the contract has run its course.
Im just looking to observe this one. if anything this thing might work as a money market fund without fees and pretty close to libor. sort of like IBs EFPs
