The only thing that has changed is one of your biggest players in the tens, prop guy from JP Morgan appears to be long a boatload of Dec this time around, he was the one short a ton of June last time, ended up costing Morgan their quarter in terms of earnings. I would put him long 50,000+ in Dec, around 110-20, little lower. He has wanted to be short interest rates for awhile and had to throw in the towel last time, if he's long I wouldn't try to get short too much. Not to mention Gross' long position, Goldman really the only one selling this on the way up, has been selling Dec today. Has been a good strategy, sell into rallies pre non-farm payrolls, and slowly cover into the FOMC meetings as we rally most times after. In my opinion, the economy is slowing and Fed may have to start easing in a year or two and this strategy may not work anymore. I hope someone argues otherwise.
