VIXpiration April 2026: What Happens to the S&P 500 on VIX Expiration Day?
April 13, 2026 · 4 min read · SPY
What Is VIXpiration?
Every month, VIX options and futures expire at the CBOE — and not on the same day as equity options (OPEX). While the regular OPEX expiry takes place on the third Friday, the VIX settlement is calculated 30 calendar days beforehand:
Basis: Third Friday of the month (calendar)
VIX Settlement: Basis minus 30 calendar days → typically a Wednesday
Holiday rule: If the basis Friday or the settlement Wednesday falls on a NYSE holiday, settlement is moved forward by one trading day
For April 2026, this means:
Date

Why Is This Relevant for Traders?
Systematic things happen around VIXpiration. Institutional traders and market makers must roll or unwind their VIX hedges. This creates measurable patterns — not just in the VIX itself, but also in the S&P 500.
On the new VIXpiration page we analyzed all VIX settlement dates over the past 21 years and measured SPY returns around the expiration day.
What Do the Data Show?
VIXpiration SPY chart — cumulative return and volatility around VIX expiry
The chart shows the average cumulative return path for SPY around VIXpiration (t=0). Some observations:
1. The Day Before Settlement (t-1) Is the Strongest
With an average return of +0.64%, the Tuesday before VIX settlement is historically the best day in the window. The win rate is just under 62%. This is not a coincidence — on Tuesday, the final VIX positions are rolled, and the unwinding of hedges creates buying pressure in the S&P 500.
2. The Day t-2 Is the Weakest
Two days before settlement — the Monday before — historically shows the greatest weakness at -0.38%. This is where position adjustments begin, and uncertainty about the settlement weighs on prices.
3. Volatility Drops on Expiration Day
The volatility chart below shows it clearly: the 1d volatility (gold bars) falls noticeably on settlement day (t=0) and in the following days. The 5d volatility (green line) confirms the trend on a smoothed basis. This is the classic volatility compression around expiry — uncertainty is resolved, hedges are wound down, the market calms.
4. Prices Tend to Rise After Settlement
From t+1, the trajectory turns upward. The cumulative return rises from +0.30% on settlement day to +0.68% three days later. The post-VIXpiration phase benefits from the gamma exposure of market makers declining and the market being free to move.
What Does This Mean for This Week?
The VIX expiry on Wednesday, April 15, 2026, is approaching. If the historical pattern repeats:
Monday 04/14 (t-1): Historically positive (+0.64% avg.) — but the strongest day is tight
Wednesday–Friday (t+1 to t+2): Historically quieter phase with an upward tendency
Of course, there are no guarantees. Current macro events can overlay the pattern at any time. But the statistical base of 21 years is solid enough to keep an eye on the VIX calendar.
