Quad witching is the third Friday of March, June, September and December, when stock options, stock index options and stock index futures expire together. The fourth class, single-stock futures, no longer trades in the U.S. in any meaningful way, so most of what you will see today is really triple witching. For an options trader, the day matters for one reason: positions you hold expire, and you have to decide what to do with them. The next one is December 18, 2026.
TL;DR
- Quad witching falls on the third Friday of March, June, September and December. The next date is December 18, 2026.
- Expect heavy volume, especially near the close. Heavy volume does not guarantee big price swings, and it gives no direction.
- Your real choices on any expiring option are close, roll, exercise or let it expire. Decide before Friday, not during the final hour.
- Settlement style, exercise style and your broker's cutoff decide your risk. Read the contract, not just the calendar.
- The label is not a trade signal. Trade the catalyst, the liquidity and your defined risk.

What quad witching means
The name comes from four kinds of derivatives that historically expired on the same day: stock index futures, stock index options, single-stock options and single-stock futures. Investopedia's definition notes that the last trading hour is often called the "witching hour." The term sounds dramatic, and the mechanics are fairly ordinary.
The U.S. detail most explainers skip: single-stock futures generally no longer trade domestically. In practice, the expiration flow comes from three places:
- Equity and ETF options that expire on the quarterly Friday.
- Index options.
- Index futures, such as the E-mini S&P 500, which is worth 50 times the index level and is cash-settled.
So when someone says "four," do not assume four equally active markets. Three do the work.
Quarterly expirations land on the same day as the monthly options expiration, so you may hold contracts that would have expired anyway. What is different is the amount of institutional position management stacked on top of it.
Quad witching dates for 2026
The dates are the third Fridays of the four quarterly months. According to the Investopedia explainer, the 2026 dates are:
| Quarter | Date |
|---|---|
| Q1 | Friday, March 20, 2026 |
| Q2 | Friday, June 19, 2026 |
| Q3 | Friday, September 18, 2026 |
| Q4 | Friday, December 18, 2026 |
Three of the four are behind us as of October 23. That leaves December 18, which is also the last quarterly expiration of the year. If you hold December contracts, start your checklist the week before, not the morning of.
Holidays can shift expiration earlier in the week, so confirm the exact last trading day for each contract on your broker's platform or the exchange calendar. The time-to-expiry rules we cover on our blog explain why the cutoff you assume may not be the one your broker enforces.
What usually happens on the day
The main driver is position management. Investopedia describes market makers closing or rebalancing hedges and traders rolling contracts, with index rebalancing adding more flow. Institutions that hold futures or options as hedges have to close them or move them to the next quarter. Market makers who hedged option books with shares or futures adjust those hedges as options expire or finish in or out of the money.
The result is volume. Santander's explanation cites September 18, 2020, when about 14 billion shares traded, roughly 40% above the three-month average. CNBC reported a similar pattern for earlier quad witching sessions. If you want a refresher on reading volume in general, our guide on why options volume signals moves is a good companion.
Two cautions keep this honest.
The crowd is spread out more than it used to be. Santander notes that electronic execution lets investors distribute trades before the final hour, so the old picture of everything hitting at once is dated. The close can still be crowded, but it is not always a single burst.
Volume is not volatility. Tony Zhang of OptionsPlay told Nasdaq that traders should not be spooked, and that quad witching is not statistically more volatile than every ordinary expiration Friday. You may see short-lived price dislocations near the close. You may also see a quiet tape.
Why this matters for your options positions
If you trade options, you do not need a view on what the market does that Friday. You need a plan for each contract you hold. Expiration forces a decision, and the cost of a bad one is usually a rushed fill or an unwanted share position.
The four choices
For any long or short option approaching expiration, you can:
- Close it. Sell what you bought or buy back what you sold. This is the cleanest way to lock in a result.
- Roll it. Offset the expiring position and open a later-dated one.
- Exercise it. Available if you hold a long option and your contract style and broker permit.
- Let it expire. Fine for options far out of the money. Risky near the strike.
All of this is subject to the contract terms and your broker's rules. A short option that finishes slightly in the money can turn into an assignment you did not plan for. Our retail trader's guide to options assignment walks through how that happens and what the account looks like afterward.
Rolling is not a free extension
Rolling feels like postponing a problem. It is actually a new trade. Buying back the expiring contract and opening a later one can change your strike, the spread you pay, the liquidity you trade in and the implied volatility you are exposed to. It can also have tax consequences, so talk to a tax professional about your own situation before you make rolling a habit.
A good test: if you would not open the new position fresh today at this price, do not roll into it just to avoid closing the old one.
A pre-expiration checklist
This is the process we suggest, built from the mechanics above and the contract-specification approach CME's education material teaches.
- List every position expiring that Friday. Include spreads, since one leg can expire in the money while the other does not.
- Check moneyness. How far is the underlying from each strike? Positions within a percent or two of the strike are the ones that surprise people.
- Check open interest and the bid-ask spread. Wide spreads on thin strikes make closing expensive. Our piece on open interest regimes shows how to read crowding at a strike, and the liquidity filter presets help you set minimums.
- Confirm exercise style and settlement type. American or European, cash or shares.
- Find your broker's cutoff. Exercise instructions and expiration handling can have deadlines that differ from the market close.
- Decide in advance: close or roll. Write down the price at which you will act.
- Use limit orders. Do not chase the closing surge with market orders.
- Confirm the outcome after expiration. Check your positions, shares and cash on Monday morning. If you were assigned, you want to know before the open.
A short, written list beats improvising at 3:45 p.m. Our options entry rules use the same logic on the way in: define the trade before the emotion arrives.
Settlement and exercise: read the contract
This is where experienced traders separate from the rest. Not every option behaves like a standard equity option.
Stock and ETF options are typically American-style and physically settled in shares. That means a short call that finishes in the money can leave you short shares, and a short put can leave you holding them. Early assignment is possible before expiration, particularly around dividends, which we cover in our piece on avoiding assignment on ex-dividend options.
Many index products work differently. CME documents that some index options are financially settled, with all expirations settling directly to cash at maturity, and that European-style contracts remove early assignment. That changes your risk completely. A cash-settled European index option can only be exercised at expiration, so there is no surprise share delivery on Tuesday.
Futures are a different animal again. Leaving an E-mini position open through expiration is not the same as holding an equity option. The contract is cash-settled and carries 50 times the index level, so a small move is a large dollar amount.
The practical rule: before the third Friday, pull up the specification for each product you hold and check your account permissions. If you hold an option that settles in shares and you do not have the buying power or margin to take delivery, close it before the cutoff.
When something goes wrong
Sometimes a position is assigned, exercised or left open when you did not mean it to be. Treat that as a process failure to fix, not a reason to panic. A written risk management workflow helps here, because it defines in advance who acts, at what threshold and with what size. Then call your broker's trade desk with the facts: the position, the time and the outcome you need.
Our perspective
Most of the commentary around quad witching treats it as an event to predict. We treat it as a calendar item to manage. The day has a known structure, and the useful questions are about your book rather than the market: what expires, what is liquid, what could be assigned and what you would do if the close gets messy.
We also see traders make the same mistake in the other direction, stretching a thin edge by trading the label itself. Quad witching is a market-structure event. It does not tell you a stock will rise, fall or "explode." What does is the same set of things that matters every other day: a real catalyst, unusual volume or open interest, enough liquidity to get out, implied volatility that is cheap or rich against what the stock actually does, clear technical levels and a bear case written down before you enter.
That is how we build the briefing. Each idea is vetted, scored and given entry levels and a bear case, so that on an expiration Friday you can spend your limited attention on the positions you already hold. For busy professionals and business owners who trade around a day job, that matters. You do not have the hours to watch the close tick by tick, so you need your decisions made the night before.

Do not trade the label
Two questions come up around this topic that deserve a straight answer.
"Which stocks will explode on quad witching?" None can be named on that basis. There is no authoritative evidence that quad witching makes a particular stock jump, and higher volume on the day does not mean higher volatility. If a stock moves, look for the catalyst: earnings, news, an index rebalance or a big options position at a nearby strike. Our guide to the 15-minute rule for news catalyst trading shows a repeatable way to check one.
"What is the 3-5-7 rule?" It is not an exchange or regulator rule. Nothing from the OCC, SEC, Cboe or CME defines it, and the authoritative explanations of quad witching cover expiration, exercise, rolling, settlement, volume and hedging, not a 3-5-7 rule. Some traders use that phrase for their own risk heuristics, and those differ from person to person. If you use one, know exactly who defined it and treat it as a personal guideline, not a requirement.
Prepare the week before
A calmer expiration Friday starts earlier in the week.
- Monday to Wednesday: list expiring positions, flag any near the strike, and decide which ones you will close early. Closing Wednesday often costs less than closing at 3:55 p.m. on Friday.
- Thursday: confirm broker cutoffs, buying power and margin. Check whether any short leg could be assigned.
- Friday morning: place limit orders for planned closes and rolls. Review pre-market news for names you hold.
- Friday afternoon: avoid new, large positions in the final hour unless that is your specific plan. The close can be crowded, and spreads widen.
- Monday: reconcile. Check assignments, share positions and cash.
None of this requires you to predict the market. It requires you to know what you own.

FAQ
What usually happens on quad witching day?
Trading volume rises as institutions and market makers close, roll and rebalance expiring positions, with the heaviest activity often near the close. Prices can show short-lived dislocations, but higher volume does not guarantee higher volatility. Many quad witching sessions look like any other expiration Friday.
What are the quad witching dates for 2026?
They are March 20, June 19, September 18 and December 18, the third Fridays of the quarterly months. As of October 23, 2026, the next one is December 18. Check your broker's calendar for any holiday-related changes to the last trading day.
Is quad witching the same as triple witching?
In the U.S., effectively yes. The fourth contract class, single-stock futures, generally no longer trades domestically. The expiration flow comes from stock options, index options and index futures, so the terms are often used interchangeably.
Should I close my options before quad witching?
There is no universal answer, but positions near the strike or in thin strikes deserve the most attention. Decide in advance whether to close, roll or let each contract expire, and use limit orders. If a contract settles in shares and you cannot take delivery, close it before your broker's cutoff.
