Decay of next month sets in once before current months positions starts getting rolled over to next month and then 1-2 weeks before actual expiry...
To keep things simple, I mention a linear decay in timevalue from current TValue to 0 on the day of expiry, but theoretically the graphs is logarithmic (or exponential, don't remember exactly).
So while front month option, due to lower life decays at much faster rate, far month option decays at comparatively slower rate. This gaps between decay of both options timevalue widens near the expiry of front month option, cause they start loosing value at much faster rate.
Effect of intrinsic value is same on both options.
Personally, I prefer next months options since it gives me a chance to off set some of the risk using current months options. But it can back fire also...
I bot 5200 call of this month at 52 (sl 44) to offset some of the possible risk of the shorts i'm carrying of the next month.
