VVIX Explained: What the Volatility Index Tells Traders

VVIX Explained

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

S&P 500 options gamma chart showing left and right tail risk zones with strike prices and gamma levels.

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 […]

Flat Index Masks Hidden Chaos

SPX put skew chart showing elevated downside hedging with call skew at low levels as of February 13, 2026.

Overall price stability in the S&P 500 is masking one of the most unusual equity environments in recent years. While SPX has been roughly flat over the past month, the average constituent has moved 10.8% — a 99th percentile dispersion reading, as we discussed in our Thursday AM Founder’s Note. All signs point to increasing fragmentation beneath […]

The Market’s 0DTE Underbelly Is Exposed

SPX options data showing strike prices, net open interest, and gamma exposure throughout trading hours on Feb 4, 2026.

Last week reminded us just how fast market stability can give way to volatility. After trading near all-time highs at 7,000, the S&P 500 fell 3% in just three sessions, closing Thursday at 6,798 amid weakness in software and crypto. Our last Sunday Newsletter focused specifically on how this type of fragility underscores today’s market. This […]

SPX Touches 7,000 and Cracks — What Makes This Market So Fragile?

Chart showing cumulative dealer gamma (positive) and non-Odte dealer gamma (negative) across strike prices, with bars indicating gamma levels.

Market Fragility in the Face of All-Time Highs As the S&P 500 pushes record highs, the options market continues to flash warning signals beneath the surface. Underlying risk from volatility discrepancies and index-equity correlation suggest an environment prone to vol spasms — similar to what we witnessed with Thursday’s (1/29) sharp selloff and reversal. These […]

Vanna Fuels Market Rally as Market Fears Subside

Volatility skew chart showing downside vol decreasing from Tuesday to Friday while upside vol spikes, with three comparable trading dates tracked.

Last week began with fear dominating market sentiment: analysts widely attributed Tuesday’s 2% SPX selloff to Greenland worries and tariff threats. As we pointed out in last weekend’s newsletter, traders had begun hedging against downside risk as put skew increased and volatility premiums rose. However, the quick turnaround back to SPX 6,900 seemed to erase any […]

Defensive Positioning Emerges as Market Rallies

VIX options chart showing total gamma and convexity across strike prices with negative gamma trend.

Traders Turn Defensive In the Face of Market’s Climb SPX tested fresh all-time highs last week, with positive gamma providing guardrails for the broader market. In the face of headline noise—from criminal investigations into Powell to Iran-related escalation—the market absorbed every dip, with the 6,890 Risk Pivot level from Monday’s AM Founder’s Note holding firm. However, increasing put skew and […]

Strong 0DTE Support Lifts the Market to Record Highs The S&P 500 kicked off 2026 by grinding through a week of macro data releases to finish at fresh all-time highs on Friday. SPX closed at 6,966, up from the 6,902 open on Monday, after finding critical support in the 6,890–6,900 zone multiple times throughout the […]

Record 0DTE volume reshapes the S&P 500

Dual-line chart tracking SPX implied volatility over time with annotation marking current position in early January 2026.

Record 0DTE Volume in 2025 Has Changed the Game We wrapped up 2025 with the S&P 500 up 18% for the year—a solid result in the face of tariff headlines, global conflicts, and inflation concerns. One of the major options market stories of the past year has been the growing role of 0DTE options: same-day expiration […]
