Quiet Oil Options Mask Tail Risk

Dual line charts of rolling 20-day return correlations for SPY vs USO and USO vs VIX from 2019 to 2026.

Oil prices drove headlines this past week amidst flare-ups in the ongoing Iran conflict. WTI crude broke above $100 on September 15, and diesel fuel hit an all-time high of $6.31 per gallon. The mystery is that despite the price spike, the options market for oil remains unusually subdued. The CBOE Crude Oil Volatility Index […]

Hedging Against a Volatility Spike: VIX Calls vs. SPX Puts

Two SpotGamma charts show SPX vol smile and VIX half frown of implied volatility versus strike.

A series of major market catalysts arrive next week: the FOMC rate decision, VIX Expiration, and September Triple Witching OPEX. Options positioning suggests that institutions are already paying up for event protection. Over the past two weeks, we have observed notable VIX hedging activity in our daily FlowPatrol reports. This included several particularly significant positions: […]

AI Infrastructure Runs Hot into September

Two profit/loss charts for MU stock showing break-even points around $1,000 strike with expiration on 2026-09-29.

August closed with robust corporate earnings, and nowhere was that clearer than in the AI trade stocks. Last week’s standout report came from Dell (DELL), which jumped 16% after beating estimates and raising guidance. Dell is a leading server provider for AI data center infrastructure. Its results echoed what Nvidia (NVDA) showed a week earlier: […]

Software Earnings Reignite Risk Appetite

SPY options gamma chart showing strike levels 120, 175, and 200 with positive and negative gamma peaks.

Market sentiment was mixed last week following NVDA earnings and Jackson Hole. While NVDA’s solid outlook pushed the market to within inches of all-time highs, Warsh’s hawkish tone seemed to increase the probability of a September rate hike. Throughout August, the S&P 500 has closed in a narrow 2.6% band (SPX 7,600 – 7,800). The […]

Volatility Has Compressed. What Happens Next?

SPX term structure chart showing implied volatility declining from 32% to 10% across expiration dates through October 2026.

The S&P 500 pulled back slightly last week, and the market’s recent volatility compression phase appears ready for a reset. With earnings season largely over, both index and single stock volatility have dropped from the elevated levels that prevailed earlier this summer. Our pre-market Founder’s Note on Friday explained how substantial short-options positions cleared with […]

How Traders Can Play Low Volatility Environments

SPX options payoff diagram showing profit/loss curves with key strike levels and walls marked between $7,500-$8,000.

The S&P 500 has spent much of the summer grinding steadily higher to achieve record highs. Meanwhile, implied volatility has reset toward yearly lows for both major indices and many single stocks. When options become this cheap, the price of volatility itself can open new trading opportunities. The Term Structure chart reveals current SPX at-the-money […]

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 […]
