Oracle Earnings Preview: $638B AI Backlog vs. an 11.5% Options Implied Move

Doves Fly into August Jobs Report

August Jobs Report Preview As Doves Fly

Friday’s 8:30 a.m. ET Employment Situation report has the potential to be the biggest bond-market catalyst since Jackson Hole, yet the options market is pricing a contained move. A look at SPX term structure, fixed strike vol, and dealer gamma ahead of the print.

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.

SPY forward IV prices Jackson Hole as a non-event, but CTAs are stretched short Treasuries and SPX gamma flips near 7780 — an asymmetric setup into Friday.

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. Last Sunday, we wrote about how extreme options positioning into major catalysts could spark the exact volatile market behavior observed over the past several days. Tuesday’s wild 200-point […]

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 […]

How One Key Level Drove Last Week’s Rally

SPX gamma exposure and net OI chart showing price movement with negative gamma spike and Iran headline event on Mar 31, 2026.

The S&P 500 bounced back 2% last week after scraping against 6-month lows. Mixed headlines on the Iran conflict explained much of this tug-of-war, yet markets are still holding their breath. For many traders, the rally felt counterintuitive: How can equities rally so furiously if geopolitical uncertainties remain unresolved? When looking at Tuesday’s major bounce in […]

The New Volatility Regime

SPX options gamma chart showing total gamma line and bar chart with JPM strike at 6475 marked.

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

Stacked bar charts showing March 20, 2026 OPEX delta notional breakdown by asset class, with calls vs puts distribution percentages.

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. […]

March OPEX: Tipping Point or Turning Point?

Two charts comparing SPX 1-month realized volatility against VIX implied volatility from 2000-2026, with their spread displayed below.

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 […]
