FOMC Reset: Vol Crushes, Stocks Lift Higher

Last week began with quiet anticipation of Wednesday’s FOMC. When the Fed announced the 25 basis point rate cut and Treasury bill purchases, the reaction was immediate. Equities surged, with the SPX breaking out above our 6,845 Volatility Trigger to approach all-time-highs near the 6,900 resistance level. The options market had priced in meaningful event-related volatility surrounding FOMC, and […]

This is a trend we’re watching closely: Softer demand for volatility (options) […]

Negative Gamma Fuels Extreme Volatility

There’s really only one way to summarize the past few days: “What a week!” Markets delivered some of the most extreme intraday swings of the year, culminating in Thursday’s violent selloff and Friday’s equally dramatic reversal—one of the sharpest two-day sequences we’ve seen in 2025. As of Thursday, the S&P 500 was on track for the worst […]

SPX Down, Vol Up: What Makes Last Week’s Selloff Different

The market experienced a meaningful shift this week as SPX declined nearly 3% from the all-time highs of October 29, closing Friday at 6,729. What began as fluid, transient price action evolved into more concerning market dynamics by the end of the week. The week’s volatility behavior differed markedly from the tariff-induced selloff on October […]
