Welcome to the Summer Melt-Up

DRAM options gamma chart showing total gamma curve, call/put gamma bars, and volatility points at $45 and $61.5.

The S&P 500 delivered a high octane four-day run last week, establishing all-time highs with a 6% rise from weekly lows. Shifting interest rate expectations, easing Middle East tensions, and strong corporate earnings powered the dramatic rally. The sharp surge brought out notable divergences across the tech space. Software outperformed the broader market, with strong […]

The New Normal in Volatility Takes Shape

Options implied volatility skew tables for SNDK and SMH showing strike prices and expiration dates through September 2026.

The final week of July proved to be quite dramatic. An FOMC decision, PCE inflation data, and the Super Bowl of Q2 earnings all took place over the span of just 2 days, with companies representing 36% of the S&P 500 by weight reporting results last week. The results were extreme: U.S. 30-year treasury yields […]

Big Tech Earnings and FOMC Collide

NDX term structure chart showing implied volatility across expirations from July to August 2026, with peaks at FOMC and tech earnings dates.

The Dispersion Unwind Arrives Last week, we noted in our pre-market Founder’s Note that markets were skating on thin ice. In addition to growing macro risks, COR1M had collapsed below 8 signaling extreme dispersion between index and single-stock volatility. After our Risk Pivot level was breached on Thursday, the growing negative gamma environment amplified the […]

Will the AI Unwind Finally Spill Over?

SPX put and call gamma impact chart showing strike prices 6935-8080 with total gamma line peaking near 7535 strike.

Last week delivered a string of constructive catalysts that supported the market through Thursday. Inflation ran cooler than expected, bank earnings impressed, retail sales beat, and ASML and TSM offered encouraging commentary towards semiconductor demand. While hostilities with Iran escalated, the market remained quite stable until Friday’s 1% drop following the Kimi-3 announcement. The stability […]

NVDA earnings vs. a stretched S&P 500

Volatility skew chart for NVDA showing call skew above the 90-day range with implied volatility on the y-axis and strike price on the x-axis.

For the fourth consecutive week, the S&P 500 has struck records highs. This week’s breach of SPX 7,500 even arrived in the face of hotter-than-expected CPI and PPI prints — data that historically would have triggered a meaningful selloff. The tone shifted somewhat on Friday, as the rally lost steam into monthly OPEX. The week […]

The AI Trade Roars — But for How Long?

SPX term structure chart showing implied volatility curves from May to July 2026 with two circled peaks.

Last week, strong earnings pushed both the S&P 500 and Nasdaq to — once again — achieve all-time highs. Through the fast and furious AI-driven rally of the past 6 weeks, SPX has climbed 15% while NDX has surged 28%. The market’s pace of advance is well beyond historical norms, reflecting an exceptionally aggressive repositioning […]

Quiet Indices, Roaring Stocks: the Volatility Dispersion Trade

Four-quadrant scatter plot comparing IV rank and volatility levels across stocks and indices, with AMD, NVDA, and QQQ highlighted.

Robust Mag7 and semiconductor earnings have reinforced investor confidence in the AI trade, lifting the S&P 500 and Nasdaq to fresh highs. Index implied volatility (IV) — the options market’s expectation of future price movement — reset to its lowest level in three months. Despite the backdrop of the Iran conflict and heightened oil prices, […]
