These are the 6 strikes carrying the most dealer gamma in SNOW right now. The heaviest is 340 at +18.4M per 1% move, 0.5% above spot — that is where hedging flow concentrates, and where price tends to slow down or stall.
| Strike | Net gamma | From spot | Effect |

| 345 | +4M | 2.0% | pins price |

As of the latest session, SNOW is trading at $338.39 (+0.35% on the day). Net dealer gamma is positive, with the zero-gamma flip near 336.1. The call wall sits at 340 (upside magnet / resistance) and the put wall at 330 (downside level). Max pain is 320, and the options market is pricing a 1-sigma expected move of about ±1.4% (ATM IV 37%).
SNOW is perched right on its flip. Spot 338.39 is only +0.68% above 336.1 — about 0.5× the move the options are pricing for a single session. Technically still positive gamma, but with no margin: a normal day's range reaches the level where dealer hedging flips from damping moves to amplifying them. This is the setup that looks calm and isn't.
The gamma is stacked above spot: +$54M sits overhead against +$17M underneath, a 3.1-to-1 skew. That imbalance is a magnet — dealer hedging leans price upward toward 340 — but it is also why there is so little to catch SNOW if it goes the other way.
One strike dominates the map: 340, carrying +$18M 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.
The options market is pricing a 1-sigma move of ±1.4% (±$4.67) into the nearest expiry, with ATM implied volatility at 37% — neither stretched nor giving anything away.
Spot is effectively at the 340 call wall (+0.48% away), the top of a 330–340 band worth 3.0% of price. This is where hedging flow does the most work: expect supply into strength until the wall is decisively cleared.

SNOW is technically in positive gamma, but only just — spot sits +0.68% above the 336.1 flip, inside 0.5× a single session's expected move. The regime is intact but has no margin; a normal day's range can flip it.
About +0.68%, which is roughly 0.5× the ±1.4% 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.
SNOW's flip is 336.1, with spot at $338.39. The level SNOW would have to lose is 336.1, about 0.5× the ±1.4% one session is priced for — inside a normal day's range, so this regime is not safe.
SNOW's call wall (340) is a magnet and resistance; the put wall (330) is support in positive gamma but a through-level once price is below the flip.
320, for the 2026-09-18 expiry — expiring today. Spot is $338.39, so max pain sits 5.4% below the current price — and with positive gamma this close to expiry, that gap is the pin risk.
About +60M per 1% move into the 2026-09-18 expiry — and with spot above the zero-gamma flip, dealer hedging works against the move and damps realised volatility. GEX describes the character of the tape, not the direction. How dealer gamma works →
