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 […]

Space Stocks: Oversold Bounce or Ready for Liftoff?

Compass chart showing space stock tickers positioned by IV rank and risk reversal, with RKLB highlighted in yellow box.

Last month, space stocks rocketed their way onto every trader’s radar. SpaceX’s record-breaking June IPO (SPCX) drew a wave of retail and institutional attention to the sector, while a string of NASA announcements made headline news and fueled several meaningful moves. Overall, the space sector has been defined by a notable downtrend in the past […]

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 […]

Volatility Approaches Record Lows — Is It Priced Too Cheap?

SPX term structure chart showing implied volatility curves from July through September 2026, with major events labeled.

The S&P 500 spent early July grinding higher with sector rotation quietly forming beneath a calm index. As SPX price action remained relatively muted over the past week, implied volatility dropped to near-record lows as of Friday: IV for contracts expiring next week now sit in the 6-10% range. Regardless of any directional bias for […]

The AI Trade Unwinds

Total gamma bar chart with line showing peak negative gamma around 545 strike and positive gamma spike of 610 at higher strike levels.

Wall Street’s historic weekly winning streak came to an abrupt halt last week. On Friday, a sharp NFP report drove the S&P 500 down over 2.6%, leading to a sharp AI selloff and rising bond yields. Adding fuel to the fire, the market now appears to be pricing in a rate hike by the end […]

June Catalysts Threaten a Volatility Spasm — How Are Traders Positioning?

Heatmap comparing IV rank versus skew rank for top 25 S&P 500 and Nasdaq-100 stocks as of May 29, 2026.

The S&P 500 has posted fresh record highs for the ninth straight week. Tech and semiconductor earnings fueled much of the recent surge, with SNOW climbing 52%, DELL gaining 57%, and MU surging 28% within one week. As we move into June, stretched positioning now meets a cluster of major catalysts. Three upcoming events will […]

Record Highs and Thinning Hedges

SPX implied volatility term structure chart showing economic events from May to July 2026, with peaks at PCE, NFP, CPI, and FOMC dates.

Last week, the S&P 500 closed its eighth straight weekly gain — the longest streak since 2023. As the rally continues to achieve record highs, underlying options positioning has evolved meaningfully since March. Most importantly, the market has quietly shed much of the protective hedging that was in place just two months ago. A dense […]

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 […]
