Key dates ahead:
- 9/19: OPEX
Update 9/18: We look for the rally to continue into Friday OPEX, and then look for a correction next week. 9/30 is circled as potentially a more destabilizing expiration.
9/16: Our core view one is vol is cheap. We like short term put structures >=1week to 1-month out. For bears a break of <6,600 gives bears the edge, and we’d look for a test of 6,500 (JPM EOM strike). Longer dated calls also make sense >=1-month to Dec – but we prefer to wait for post-FOMC to play these (i.e. we can “wait and see” to play upside), but we can’t argue with traders who buy some upside calls as 10-11% IV
Key SG levels for the SPX are:
- Resistance: 6,700
- Pivot: 6,600 (bearish <, bullish >)
- Support: 6,600, 6,500
Founder’s Note:
Futures are +80bps higher, sitting on the 6,650
Call Wall.
Vols are down across the board, with the VIX -2 pts from pre-FOMC to 14.7.
TLDR: We still think sneaky move into Friday to 6,700 is possible, then correction next week (i.e. reversion from overbought). We look stay risk-on with SPX >6,600. The possibility for a larger down move post-9/30.
We still have net negative gamma above, which implies a chase dynamic into 6,700. Further, the overnight move of 80 bps in SPX is a 13-14% implied vol, with all ATM/near the money IV’s at 10-11% (yes, all pre-9/30 ATM IVs are 10%’s). So negative gamma + IV’s underpricing the catch-up may keep 6,700 on as a short term target (1-2 days). We’re also looking for 1-2 days of meme-mania/thematic single stock chasing: TSLA +430, IWM +1.5% premarket, BTC +1.3%, etc.
If the “chase into Friday PM” plays, then we’d have a pretty stretched market into Friday’s OPEX (up 4-5% in 2 weeks) with IV’s dead. That is a recipe for short term consolidation next week.
SPX fixed strike vol, while low, is curious. All pre-9/30 expiration IV’s are off more that 1 vol point vs Tuesday night (pre-FOMC), while post 9/30 are more flat. 9/30 is month end, but it also holds the massive JPM collar position, which in theory has dealers loaded up in gamma. We need to keep eyes on 9/30 as a destabilizing date as this positioning could roll off.
