Quote from mcurto:
We were very dead yesterday, although seems like someone at Goldman is short and continues to sit on the offer around 105-08 give or take a few ticks in the 10yr, probably a play ahead of an expected weak 3yr auction. Only thing of notice yesterday in options land was a big NOB options play again. This time selling 17,000 Sep 103-106 strangles in the 10yr versus buying 10,000 Sep 103-108 strangles in the 30yr. This is another steepening play in the NOB, or at least my take on it. Risk arb, any help on the greeks side?
