...And a little note on my 'revenue-neutral':
Skews are skewed, and thin markets are thin, and sometimes 'reality' bites.
("Well, that's just *great*, Tom -- but what does that have to do with....")
I'm getting there.
If you price your ITM March16(?) put spreads in XLE right now, you'll likely find them a scootch higher in the short delta (CL, at least, has risen a bit, and time has moved on...) -- let's say it's -0.90. If you check the OTM call at that strike (70.5??), you'll find it to be almost exactly 1.0 - 0.90 = 0.10.
("Thanks for the reminder. But 'so what'?")
Well, here's the thing: if you're looking at a 70.5/69.5 spread, if it was 87¢ earlier, it's easily 90¢ now -- [the assumption being that the rising market was beaten by the ongoing time burn, and loss of vol from 20+ to the current 17-ish VIX, or,
[position delta {gain}] < [position theta {loss}+ position vega {loss}]
("Okay. And...?")
If you go out in time, and say, down in strike, and find that instead of 90¢, you only get 80¢ for a ITM 68/69 in XLE. The sale price *diminishes* as you inject more time value into the long position. ("Ouch!") BUT!!! What happens to an available CALL spread -- that is OTM??? Ah! As you go out in time, that value increases.
And here's the thing: As the sum of the short deltas of a put spread and a call spread at the same strike should be |1.0|, so to should the sum of market premium for a same-width call spread and put spread at/near the same strike, equal the width of the spread. Thus, if you get "only" 80¢ for selling the already ITM $1-wide put spread, you should expect to get about 20¢ for the mirror/matching OTM call spread.
("Isn't that, like, "Options 101"??)
Sure, but 1) I was busy 2) I rarely deal with ITM, and question everything that comes to my mind, because your intuition, your instinct, your expectations can all be 180° wrong and you won't realize it until The Cosmos wakes you up in the middle of the night to poke you in the brain and ask, innocently, "Really? What you were thinking about _______? Really?" So, I try to avoid those Conversations-with-The-Cosmos....
And perhaps most important, 3) It ain't always so. The models work this way; most of the time, the markets work this way. But when they don't: "Ugh." For example: if you try this in the SPX right now, you'll likely find it works fine up top, but an ITM call spread?? Uh-ohhhh.
Let's see:
for Feb28, a $5 wide 2650/2655 call spread has a +0.913 δ, and a mid of $4.75
so, for parity, we'd expect the short put to carry a -0.087 δ, and a mid of $0.25
HA! That's what it is!!! It adds up to $5 for the spreads and |1.00| for the deltas. Huh! Last night, I saw $4.70 adding the call and put premium; I didn't check the deltas.
Well, something to think about for y'alls......."The market *may* or *may*not* behave as we expect."
