Quadruple‑Witching Carnage
Quadruple‑Witching expirations reportedly wiped out about $5.7 trillion in options today, amplifying intraday volatility and washouts (x.com). Traders and TV panels are blaming the witching session for the rout even as they debate whether the selloff is a genuine trend or a short‑term squeeze (x.com).

(financialcontent.com) Bloomberg calculated the expiring notional as about 8.4% of the Russell 3000’s market capitalization and noted index/ETF notional volumes this March ran about 9% above year‑to‑date averages, underscoring how concentrated positioning magnified mechanical flows. (bloomberg.com) CNBC’s Fast Money devoted post‑market segments to the “massive options expiration,” with panelists explicitly debating whether the afternoon rout was driven by forced expirations and dealer hedging or by a genuine change in market direction. (archive.org) For context, Goldman Sachs and CNBC documented a record $7.1 trillion notional expiry on December 19, 2025, meaning March’s event was large but smaller than that December peak. (cnbc.com) S&P Dow Jones Indices’ March 6, 2026 press release shows the S&P reconstitution changes take effect prior to the open on March 23, 2026, a timing detail that some previews conflated with the March 20 expirations.
