Yes, if the movement after the Brexit vote is huge, just like a earning issue. But in most of case, the movement is priced-in in the premium. The implosion of IV will make it unlikely to profit by buying a straddle before such event. Statistically, ATM straddles lose money. But I DO see some people to profit the event by legging in the straddle separately many days before the event. I am not a fun of it. If I am going to play a delta neutral game on Brexit, I would rather choose to credit some DOTM ion condors. |
