There is no way there is 10 points in the daily range in ES futures spreads, H/M. You're ignoring the mid/mark in r/t and simply looking at last trade dot shots in the back contract. C'mon.
You don't start the day pricing synthetic-relationships. No counter-party is expecting a large arb-condition to appear from flow. IOW they expect that you're going to know enough to act in your own self-interest. The hedge resulting from flow is generally not going to be a conversion or box...
Synthetics have a ton of utility, not the least of which is to show you that you know nothing w/o an understanding of synthetics.
To quote a common tautology that is esp fitting here, "you don't know what you don't know."
Merry XMAS.
I am talking about what makes them equivalent... and the result is that their greeks net to zero. Stop changing the subject and hit yourself.
The ps is not worse because it's short small theta. The arbitrage makes them equivalent. You're never going to get it bc your dumb and assume you're...
They are not (different).
Buy the cs (bull) and buy the ps (bear) = box arb.
Buy the inside strangle (100C/140P) and short the outside strangle (100P/140C) = box arb.
If you're in one you can cover in the synthetic... the synthetic of the cs is the ps. It results in no greek exposure outside...
You cannot judge value on same-strike cs/ps. They are equivalent. I didn't show the synthetic but it didn't make any difference. You don't understand any of this. You still believe short spreads are "better" because they are long theta.
The arb-condition results in *zero greeks outside of rho...
Oh, you're special!
So you're short an ATM put at 0.3 and the buyer exercises. You were just paid $30 to close the position. Your risk is the same as holding the sp but now your potential gain is massively asymmetric in your favor over holding a sp and your $30 payout was accelerated.
Buy...
OK so say that spot = 100 and the weekly 70/75 put spread is nickel to buy. Which earns more? The nickel ps or the short 70/75 cs at 4.95? You're either trolling or thick and you've posed this same moronic argument in the past.
