[quote author=“capablanca”][quote author=“mtdoc”][quote author=“mtdoc”]Bought a few June 175 straddles.
Rolled these to October (essentially buying a double calendar) to get me more long Vega and lessen the effects of time decay over the next 2 weeks since it looks like we might be range bound until WWDC.
Will likely sell some June calls and puts against my long options before WWDC.
Could you please amplify this, doc. I follow how rolling to October lessens the effect of time decay, but I am unsure regarding the the double calendar reference. Straddles and are long gamma and Caledars short gamma. Are you referring to the similar shape of the P/L for both types?
And does double refer to longer than 3 months?
I originally put on a June straddle - thinking that we might get a quick move up or down and a volatility spike. Once it looked to me like this was not going to happen I rolled it to October. This meant selling the Junes and buying the Octobers - even though It was a roll because it was selling front month options and buying back month options this means the trade was a calendar spread.
I was worried the the acceleration of theta decay for front month options over the 2 weeks before WWDC would not be overcome by the expected IV increase (because rate of decay accelerates during the last few weeks before expiry). October options will not be so vulnerable to decay and back month options are always relatively more affected by IV increases than front month (which is why a long calendar is a good trade when IV is increasing)
Whenever I adjust a position or roll a position I look at the trade that I do as a new trade in itself and ask does it make sense. Rolling a straddle forward by doing a “double calendar” made sense to me since it would be a theta positive and vega positive trade.
Hope that makes sense ....
ADD: Capa - double refers to a put calendars and call calendarswit the same strikes. So rolling a long straddle forward is equivalent to doing a double calendar spread.
