Quote from donnap:
It's a simple collar. I was using the '09s to better illustrate the point. The term is more like 10.5 months. The yield above 480 is closer to 5%. Interest rates are low and this is a low risk position so 5% is a reasonable return here.
There's nothing mysterious about this. Collars are described in most option books or on the net. A risk free interest rate is factored into option pricing. Added to the call price, subtracted from put prices.
