Since you’re selling courses and claiming to be expert on institutional order flow, market structure etc, so let’s put options aside for a moment, and can you please give us (“non-institutional traders”) a quick lesson on the SPX institutional order flow?
About 20 years ago, I was mentored for 12 months by Kevin Haggerty. He was a head trader for Fidelity (one of the largest institutions in the world), and so I have fairly good idea about how the biggest intuitions work their orders, so I’ll keep you honest.
You can start with how market makers look at the order flow in their books in the morning, how they decide in which direction they’ll take the stock in the morning, how far they’ll run it up or drop it down, and their reasoning behind it.
Thanks
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 conjecture to r/wallstreetbets. (Maybe 20 years ago there was more manipulation of index...)
What do you want to know about institutional order flow in SPX, today?
It's obviously been dominated for some time now by short vol strats in some form or another. Everyone's making a big deal of the public facing ETF growth (JEPI / XLYD) but as you probably are aware, short vol has been a feature of the index space for a long time now- and especially post-2008.
If you want to get into the weeds-
I think most outside observers look at prior crashes vs current selloffs and compare spot-vol dynamics, making all sorts of assumptions that miss a very obvious and easy to grasp structural change in the market.
If you traded the crash during Q4 2018- you'll know what I mean very intuitively. A lot of the short vol used to be deployed in iron condors and short ~5-8% OTM puts inside of 6 weeks to maturity. The notional there was not trivial... at any given point in 2018 you had Harvest & UBS collectively short 200,000 SPX iron condors within 8 weeks. Additionally, you had another Put Write fund short ~200,000 SPX puts in that same time-frame.
Anyone just looking at GEX- you wouldn't pick this up, you might even think the market was "more short gamma" because of all those downside puts in the OI, but they were held long by dealers (I was one, at the time).
The functional difference then versus now- in 2018, when we'd sell off enough to pierce a defensive trigger, the fund would (systematically) come to market to close & roll their short options. This was true for the iron condors, and it was true for the puts.
So- if you have dealers continuously hedging long gamma, while you have initiators discretely hedging short gamma, you don't actually have a very supportive market when viewed solely through the lens of GEX / gamma flows. Arguably you have a more volatile one- if you conceptually think through the nature of the liquidity: a smooth absorptive bid on the way down punctuated by a liquidity-taking (options) / sell order which concentrates the entirety of the volume but all in one fell swoop.
The single biggest change structurally to the index volatility space over the last 5 years has been the collective shift out of defensive / tactical trading around short volatility positions into a mode which focuses on a greater dispersion of strikes and tenors while taking each (smaller bet) to maturity. It's overdue and intelligent- at least now the short vol strats tacitly use their positioning to their advantage- rather than the other way around.
AFAIK the only strats that have not made the shift are the GS XSP/ SPX put write & the Gateway / Nuveen overwrite... most of the other flows now have left rolling iron condors and short puts to the past, and target 7DTE tenors that are held to maturity.
That's why when people ask- "is the market different now"- waiting for VIX to show signs of life on the way down.. it's hard to say it's not. This is a meaningful change
how do you see the space
