How Options Market Structure Controls Intraday Price Action: GEX, Dealer Hedging, and the JP Morgan Collar Trade Most traders watch price. Sophisticated traders watch flow. But the traders with real structural edge watch what dealers are forced to do — because when the biggest participants in the world’s largest options complex are compelled to hedge, markets move […]
Market Analysis
The New Volatility Regime
Over the past several weeks, we have consistently highlighted the market’s growing fragility. From the negative gamma “trapdoor” to the destabilizing impact of geopolitical shocks, the message has been clear: this is no longer a range-bound market. Last week confirmed those warnings, as the S&P 500 is down nearly 9% from all-time highs. On Thursday and Friday, traders […]
After OPEX: Market Loses Its Shock Absorber
The options market has just cleared one of the largest structural events of the quarter, as Friday’s OPEX saw nearly $1.4 trillion in delta notional expire for the S&P 500. Because significant positions have now rolled off from the March expiration, the market has lost an important stabilizing force just as macro pressures begin to build. […]
VIX Expiration, Oil, and the JP Morgan Collar Trade: What’s Driving the S&P 500
Market Summary The market is entering a critical window where VIX expiration, quarterly options expiration, crude oil, and the JP Morgan collar trade are all colliding at once. The core argument is simple: implied volatility remains elevated while realized volatility has stayed unusually muted, and that mismatch may not last much longer. If oil continues […]
March OPEX: Tipping Point or Turning Point?
Fragility, Risk, and Potential Vol Reset As the S&P 500 enters OPEX week, we echo the same theme of the past few weeks: this market remains fragile. Last week’s selloff pushed the index below the three-month trading range of SPX 6,800-7,000 that had held since late 2025, subsequently closing down 5% since mid-January. The conflict with Iran continues […]
Geopolitical Risk Hits a Fragile Market
Markets entered last week on fragile footing. In our previous Sunday note, we emphasized how negative dealer gamma, extreme put skew, and heavy 0DTE options activity set the market up for a trapdoor scenario. This created a market structure vulnerable to sharp drops and spikes in volatility, as we saw play out last week. The dramatic […]
The Options Market Trapdoor
Over the past week, the topic of volatility has returned to the forefront. While the market has been largely range-bound, underlying support remains tenuous. Simultaneously, traders have begun more actively paying for downside protection. Given the backdrop of flaring geopolitical conflict, we see assymetric downside risk forming as trader uncertainty and negative gamma threaten to unlock the […]
VVIX Explained: What the Volatility Index Tells Traders
The VVIX measures the expected volatility of the VIX itself — giving options traders a window into hedging demand, dealer positioning, and what the market is pricing before volatility materializes. SpotGamma’s forward return data shows
what elevated VVIX levels have historically meant for SPY and VIX.

Right Tail Risk Is Building in the S&P 500
The market spent most of last week locked in the SPX 6,800–6,900 range that has largely held since Thanksgiving. Wednesday’s VIX expiration and Friday’s monthly OPEX defined the week’s rhythm, while negative gamma positioning and elevated single-stock put demand maintained pressure under the surface. Our historical OPEX data suggests the market is positioned for a […]
