Generally short dated strategies (that don't roll - ie, the gamma is *sticky*, actually does compress range) tend to concentrate on strangles and puts within 7dte
recent examples:
Monday- short SPX...
If you're being sincere- the presser. Premiums hold on Wednesday through the prepared remarks and Q&A. The close is usually good for *some* move- although most of FOMC-related variance tends to hit in the overnight and Thursday session historically.
Here's a few hints (this is my specialty and core interest after a career as MM /derivs sales spanning 25 yrs)...
Index MMs are reflexive- when they are strained, you will see evidence of it in the pricing.
Short vol strats abound- it's not true that index MMs are all short-put, long-call. Not...
Rules change mid-game in the US all the time. It's the only way to maintain a shell game where the ledger rarely "truly" balances net/net.
Just ask any dealer-
Market strain? "We're going to need you to post additional margin against this inventory, here"
"We're going to need you to post...
This analysis is completely asinine.
There are tons of different market makers and functional dealers in the index option markets- and the hedge instruments are the most liquid in the world.
However, when the traditional positioning is buying put / selling Call- as it *generally* still is if...
I promise you there's not much here. I was an index MM for almost two decades.
The way the brokers handling this order tend to work- they post a bid electronically (or in the crowd) and solicit counters on strike. They are looking to spend the least amount of premium to cover some absurd risk...
We are just talking different things. I don't challenge the notion that there is a massive world beyond that of options. And at times like these, when core assumptions on longer term rates are tested, for example, options & systematic flows take a back-seat.
Option & systematic flows, however...
Index MMs don't "decide which direction they'll take the stock in the morning / run it up or drop it down" etc.
That may be a feature for a DPM in an individual equity where they hold a meaningful portion of the OI, but obviously SPX / NDX etc- no single MM is playing that game. Leave that...
Institutional systematic short volatility space now has an edge baked in due to their size. This used to not be the case, because of the nature of how they would manage their positions- tactically.
Your best bet may be to piggyback the sticky inventory that doesn't get shut down or rolled into...
You are probably safe for now..
despite all the hype about 0dte options potentially causing a volmageddon- there's nothing right now to indicate this is the case. If anything, the nature of the 0dte flows contributes to a net positive-gamma effect.
What I will say here-
95% of the big...
Not following.
To be clear, what I meant to say:
dealer gamma, with respect to spot, is generally long gamma/GEX 5% around the money. Of course some nuance as spot moves between positioning resets- but I'm sure you'd agree
the "always" was not with respect to spot or to suggest they are...
