The gamma and theta characteristics of ODTE are attached at the hip. But the zero day to expiration straddle on last Wednesday’s Fed day was no normal ODTE. We might call this straddle a OTTD straddle. Zero theta to decision. The Fed decision isn’t just a date on the calendar. It’s a specific time of day on that date. It’s not like NFP which comes out before the market opens. It’s not like NVDA earnings, which come out after the close. Powell and his Fed teammates have decided they want to give us the goods during the trading day and on Fed days, “Ain't nothing going on but the rent” becomes “Ain't nothing going on pre-event.” I discuss the unique behavior of intraday option pricing on FOMC day and also how to think about the VIX floor as the US election comes into closer view. I hope you enjoy and find this useful.
