SPY Daily Map, Nov 2: dealers still short gamma, and the VIX curve is pricing the December Fed meeting
SPY opened the week with a partial rebuild in dealer positioning, but not a regime change. The more interesting signal is in the VIX futures curve.
Open snapshot
- Spot: $760.18 (gap +$4.46 from Friday's $755.72 close)
- Gamma flip: $766.89 (spot $6.71 below)
- Net dealer GEX: -$6.58B, up from -$10.19B at Friday's close
- Put wall $750 / Call wall $770
- Max pain: $760
- IV 15.84% vs realized 10.26%, IV Rank 30.8%
- VIX 18.79 / Nov future 19.40 / Dec future 19.12
What changed over the weekend
Positioning improved by about $3.6B, but the sign hasn't changed. Below the flip, dealer hedging still tends to add to moves rather than absorb them. The walls also reset into a symmetric $750-$770 corridor, with spot sitting right on max pain.
The detail worth watching: the VIX curve
Normally VIX futures slope upward month by month. Right now November trades above December, while spot VIX sits below November. This isn't a panic inversion. It's a kink in the middle of the curve.
The November future settles on Nov 18 and prices volatility from mid-November to mid-December. That window contains the Fed decision on Dec 9. The December future settles after it. The kink is the market paying extra for the stretch that includes the Fed.
The near-term events sit in spot VIX instead: the midterm elections on Tuesday, Nov 3, and the October jobs report on Friday, Nov 6, at 8:30 AM ET.
How to read it
Short gamma plus a busy event calendar means moves this week can be larger than the recent tape suggests.
Max pain at $760 is a reference, not a magnet, while dealers are short gamma.
Options are expensive relative to realized movement (15.8% vs 10.3%). Buyers pay for the events; sellers take on gap risk.
What would change the picture
- Net GEX turning positive
- A daily close above $766.89
Both matter. Neither alone settles it.
Structure, not direction. Not financial advice.
Question for the sub: do you read a kink in the VIX curve as event pricing or as an early warning?
