Your positions have nothing to do with anyone else's... Your short strangles have no effect on Dest's FLYS nor do your short strangles negate any statistical advantages of someone else's position. You are not even doing them on the same underlyings. I have seem some BS swung around but that is pretty deep .
What’s nutty is the implication that wings are the loss-engine. Decay on perhaps six cents in wings? Obv we are talking about naked combos on street vol and not index. You can’t short a two lot SPX for less than $100K under RegT. Jul6 exp: Short one ATM combo in SPX = $55K Short one 2600/2700/2800 iron fly = $6,700 Leverage factor. You can do a 15-lot fly vs. a 2-lot short straddle. Obv you’re not going to leverage because you can, but where is the stat-advantage? Over 10x the decay in the fly. Trade cash secured if you want, but that’s the only way to do it if you want to trade a naked combo in this journal. Market can go to zero and you’re out $100K in the fly. Mkt goes to zero and you’re out $540K in the naked combo. 8X the req to save $400 in premium?
Max, trade cash-secured. You sell 10 naked combos on a $50 strike at 2.20 for $2,200. $50,000 less the credit received = $47,800 haircut. Spot rallies a ton and we will mark a haircut after the close. Doesn’t make a lick of sense, though.
My point is your strategy and underlying selection are entirely your own, not a counter to someone else's "edge". If Dest puts on a FLY on TSLA and you put on a short straddle, you are going at it from different end result desires.
You replied to me, I realize, but his argument is that the difference between the two methods is the edge isolated to the wings, or lack thereof. That’s the “all options are meant to be shorted” argument taken to its terminus. IOW, “what’s the difference between a short straddle and a fly? Edge.” The edge between the TSLA fly and the short straddle has nothing to do with the wings.
Sorry just realized it was your post not his. And my point was what you said, the wings of the FLY are not the difference maker, it is strike selection and bias as well as timing for vol. So not sure I agree with his assessment his short straddles are a counter to your FLYS.
