The GEX Playbook for Quarterly OpEx

Before quarterly OpEx, check ApexVol's GEX analysis for SPY. If total GEX is strongly positive (above the GEX flip point), expect the market to pin near the highest gamma strike. Sell iron butterflies targeting that strike. If GEX is negative (below the flip point), expect amplified moves and use wider iron condors or reduce exposure. The GEX reading is the single most useful tool for quarterly OpEx positioning.

Questions

About trading this event.

What is triple witching in options?

Triple witching occurs when stock options, index options, and index futures all expire on the same day, which happens on the third Friday of each quarter (March, June, September, December). The simultaneous expiration creates massive volume, increased volatility, and unique pinning dynamics as market makers hedge and close positions.

How should I trade quarterly OpEx?

Check GEX levels on ApexVol to identify high gamma strikes. In positive GEX environments (stock pinned near high OI strikes), sell premium with iron butterflies targeting the pin. In negative GEX environments, expect larger moves and use wider iron condors or directional plays. Always reduce position sizes due to heightened gamma risk.

Is quarterly OpEx more volatile than regular expiration?

Quarterly OpEx typically sees 2-3x the normal expiration volume and can be more volatile intraday due to gamma effects and institutional rebalancing. However, the overall direction often pins near max pain or high open interest strikes. The key risk is intraday volatility, not necessarily larger end-of-day moves.
