B/c calendars are +vega and +theta? Speed kills, huh?Quote from riskarb:
All long vol time spreads are paradoxical. You need vol but not speed. Buying otm DDs is one problem.
Trying to maximize dTheta to offset any large dSpeed?Quote from riskarb:
One thing I've learned is to never trade any time spread with > 2 weeks to expiration. Trade shorter durations.
Wait, don't DDs contain both puts and calls by def?Quote from riskarb:
Don't trade concurrent put and call DDs.
Understand the latter but not the former. Why atm? Better prob of ending up at sweet spot of short strike at exp (in 2 wks or <, I assume)?Quote from riskarb:
Try to stay as close to atm as possible. Gamma kills into the strike and vega [strips, dVega/dS] away. Delta is painful anytime stat vol trades > 1 sigma.
Nitpicky Qs:Quote from riskarb:
The best time spreader I know would buy huge numbers [10k cars +] of otm put time spreads [same-strike] and get neutral [d] based upon a 7 day forward delta with index futures. IIRC, he made > $10mm one year [2001?] from a retail account. He never held a spread longer than 15 trading days.
