Jackson Hole 2026: What the Options Market Expects

SPX term structure chart showing implied volatility from August to October 2026, with Fed Press Conference event marked on September 16.

Vol Sellers Shrug off a Hawkish Fed

Line chart tracking SPX implied volatility across multiple expiration dates from June through August 2026, showing volatility decline over time.

Despite a hawkish Fed rattling equities midweek, the market easily and quickly retraced any lost ground by Thursday. With June OPEX now behind us and implied volatility reset toward recent lows, there is a soft feeling of “what’s next?” for the S&P 500 until earnings season ramps up next month. The June FOMC meeting on […]

Triple Witching + FOMC Fuels Volatility Risk

SPX term structure chart showing implied volatility and settlement levels from June to August 2026 with downward trend arrows.

The market delivered several volatile sessions last week as traders navigated Wednesday’s CPI inflation report, Friday’s massive SpaceX IPO (SPCX), and a mix of Iran-driven headlines throughout.

The S&P 500 has bounced back to record highs, closing decisively above 7,100 after Friday’s 1.2% rally. That marks a 12% rise from March lows in just under three weeks. In that same timeframe, volatility expectations have seemingly collapsed: VIX is down 40% since March 31, dropping from >30 to below 18. Crude oil has […]

Vol Crush Lifts the S&P 500 — Will the Rally Last?

SPX gamma chart showing positive gamma peak near 6820 and negative gamma regime below 7020.

Following last week’s ceasefire announcement, the S&P 500 lifted 3% from roughly 6,550 to 6,800. On the surface, this rally looked like a meaningful shift toward risk-on sentiment as implied volatility collapsed rapidly across all expirations. Similarly, VIX plummeted below 20 for the first time in four weeks, marking one of its largest single-day declines ever. Yet […]
