Quote from mcurto:
As if it wasn't enough the Japanese buying huge size in the 30yr puts as we broke, we began to stabilize off the lows, as we traded to 107-09 this afternoon Goldman bank traders quoted the June 107-109 combo vs. 107-10.5 in June (a 66 delta on this thing). Boom, they come in during the last half hour and sell 30,000 of them at 29, selling put and buying call, covered against 20,000 futures short at 107-10.5. They essentially faded this whole move today by selling puts that went crazy bid and buying calls that got hammered. They could have easily sold 20,000 more of those combos it was so well bid in the 10yr options pit. Unbelievable the balls these guys have. I think its a brilliant play, slow steady grind back to 108 in tens by June expiration (maybe trade a bit lower before then though).
