Net gamma exposure by strike ($M per 1% move) · estimated from the VST options chain (Polygon).
These are the 6 strikes carrying the most dealer gamma in VST right now. The heaviest is 150 at +5.8M per 1% move, 6.9% above spot — that is where hedging flow concentrates, and where price tends to slow down or stall.
| Strike | Net gamma | From spot | Effect |
|---|---|---|---|
| 165 | +1.6M | 17.6% | pins price |
| 160 | +2.1M | 14.0% | pins price |
| 150 | +5.8M | 6.9% | pins price |
| 135 | -2M | -3.8% | accelerates moves |
| 120 | -1.4M | -14.5% | accelerates moves |
| 115 | -2.7M | -18.1% | accelerates moves |
As of the latest session, VST is trading at $140.35 (+1.43% on the day). Net dealer gamma is negative, with the zero-gamma flip near 163.36. The call wall sits at 150 (upside magnet / resistance) and the put wall at 135 (downside level). Max pain is 148, and the options market is pricing a 1-sigma expected move of about ±6.6% (ATM IV 72%).
VST is trading below its zero-gamma flip. Spot 140.35 sits −16.39% under 163.36, which puts dealers on the wrong side of their hedges: staying neutral forces them to sell weakness and buy strength. That is the mechanical reason moves in VST are extending rather than fading right now. Until 163.36 is reclaimed and held, treat every level below as a through-level rather than support.
The gamma is stacked above spot: +$10M sits overhead against +$0M underneath, a 52.5-to-1 skew. That imbalance is a magnet — dealer hedging leans price upward toward 150 — but it is also why there is so little to catch VST if it goes the other way.
One strike dominates the map: 150, carrying +$6M per 1% move — above the current price. Positive gamma that size behaves like a wall: rallies into it get sold by hedging flow, and dips toward it get bought.
Options are expensive here: ATM implied volatility is 72%, pricing a 1-sigma move of ±6.6% (±$9.2) into the nearest expiry. At that level you need the move and you need it quickly — long premium bleeds fast, and the structure above argues for spreads over outright calls.
That leaves a working band of 135 to 150 — 10.7% of spot, with +6.88% of room to the call wall and −3.81% down to the put wall. In a positive-gamma tape the edge is fading the edges of that band rather than chasing either end.

VST is in negative gamma — spot is −16.39% below the 163.36 flip. Dealers amplify moves at these levels, so VST trends rather than pins, and downside levels behave as through-levels instead of support.
About −16.39%, which is roughly -2.5× the ±6.6% the options are pricing for one session. Under 1× means the flip is reachable in a normal day; over 2× means the regime is unlikely to change without a catalyst. We track this across every major index on the free regime dashboard.
VST's flip is 163.36, with spot at $140.35. Price is under it, so VST needs to reclaim 163.36 and hold it to get back into the suppressed regime — roughly -2.5× a single session's expected move away, which is why the level matters more than any moving average on the chart right now.
VST's call wall (150) is a magnet and resistance; the put wall (135) is support in positive gamma but a through-level once price is below the flip.
148, for the 2026-11-06 expiry — 3 days out. Spot is $140.35, so max pain sits 5.5% above the current price. In negative gamma the pull is weak: dealers are amplifying moves, not damping them toward a strike.
About +1M per 1% move into the 2026-11-06 expiry — though spot is below the zero-gamma flip, so hedging at this price runs with the move and adds to it. GEX describes the character of the tape, not the direction. How dealer gamma works →
