Key dates ahead:
4/4: Vols are getting to historically high levels, suggesting that long put holders need a reason for being - either they are hedging a portfolio or betting on downside. In either case, those puts are very expensive, and require incremental downside/bad news to justify current prices/values. Anything less than awful news and/or big declines will crush put values, and generate large, short term rallies. If weekend news is benign, then we look for a dead-cat bounce into the 5,400 area. Below, 5,000 is long term support given massive OI and that strike, and dealers holding positive gamma below that level.
4/3: Post Tariff Announcement: We want to be long of stocks >5,525 as negative gamma & a potential vol crush could quickly accelerate stocks higher to 5,600. To the downside, 5,400 continues to look like a major support zone.
3/25: Pre - April 2 Tariff Scenario/Projection:
In a positive outcome, we'd look for a move into 5,950, with major resistance at 6,000. This area is also where we believe vanna fuel would be totally "burned off" with VIX hitting 14's
In a negative outcome, the immediate downside support level to watch is 5,500. We see soft support <=5,500, with room for vol to increase. For this reason we look for a move to 5,400 in a risk-off move. 
Key SG levels for the SPX are:
- Resistance: 5,400
- Support: 5,000
Founder's Note:
Well,
that was something.
SPX -6%, NDX -6%
VIX, +15 to 45. That is the 5th largest 1-day VIX change since Jan 20.
The VIX at 45 equates to 2.8% daily moves in the SPX. So, on one had we view that +40 VIX as quite rich, but that is against a 5% decline today and a -4.8% decline yesterday. SPX 1-month realized vol is now somewhere north of 25%, and you have to go back to late '22 to find something larger.
The driver of this higher vol is options demand. Preliminary indications are that this is the largest single day
put volume.
..ever. We are sure there were a lot of margin calls were going out today, particularly into end-of-day - and there was likely a lot of put activity designed to ward of margin calls.
Where do we stand, positionally speaking?
There are reasons to believe that 5,000 should be solid support. #1, there is massive OI at that strike, and while a lot of that is related to box spreads, the big-round-number has a lot of other positions there, too. Further, there are some large dealer long puts under there, which should offer positive gamma support. Not the 0DTE/short dated kind, buy longer term, more material support.
Those of you that trade options know that theta is the tax you pay to carry an option position.
But when IV spikes, time decay (theta) becomes your major enemy. The image shows that theta is more negative at higher volatility, especially for at-the-money options. If you hold options, they’ll lose value faster as expiration approaches, unless the SPX moves in your favor. Put holders may have to have protection as a hedge - fine. But if you are speculatively holding long puts right now, you are hoping for Black Monday, and if you don't get that, you are going to be paying a very heavy tax. What does that mean? If the futures market isn't puking on Monday AM, it may generate a large equity rally as vols come in and put prices get crushed.
So while everyone is focused on the left move/downside "Black Monday" tail (which is legit), you cannot ignore something of a right tail rally either (little resistance until 5,400). From our viewpoint, its essentially impossible to pin the SPX given this extreme IV, so we have to "watch the tails".
One major cause for concern there is the credit market. Things seem to deteriorate in that space today, and if you look back at most historic vol spikes they are related to problems in the credit market (HYG bond ETF, below). If things break down there, then equities will be the tail that gets wagged, and VIX/vol can leap higher irrespective to put "value".
