How Triple Witching Works

🧙 The Three "Witches"
Triple witching occurs when stock index futures, stock index options, and single stock options all expire on the same day — the third Friday of March, June, September, and December.
📈 Stock Index Futures

Products: E-mini S&P 500 (ES), E-mini Nasdaq-100 (NQ), E-mini Russell 2000

Settlement: Cash settled at SOQ (Special Opening Quotation)

Timing: AM settlement based on opening prices

📊 Stock Index Options

Products: SPX, NDX, RUT options

Settlement: Cash settled at SOQ

Timing: AM settlement (9:40-10:00 AM ET typically)

🎯 Single Stock Options

Products: Options on individual equities

Settlement: Physical delivery (100 shares per contract)

Timing: PM settlement at market close

🕐

Critical Timing Windows

Week-Level Timeline

T-9 to T-7 (Monday-Wednesday prior week)
Early Positioning Phase
Large institutions begin shifting exposure. Volume starts increasing. Pre-expiration rally begins.
T-6 to T-4 (Thu-Mon)
Rally Continuation
S&P averages +0.82% from T-9 to T-1. Momentum traders pile in.
T-3 to T-1 (Wed-Thu witching week)
Peak Rally Window ⭐
Strongest edge: +0.47% average (134.59% annualized). Exit longs by Thursday close.
T-0 (Triple Witching Friday)
Expiration Day — AVOID
14% win rate since 2021. -0.52% average return. Stay flat or fade rallies.
T+1 to T+5 (Following week)
Post-Witching Weakness
66% of weeks negative historically. Hedging support dissolves. Watch for reversal setups.

Intraday Timeline (Witching Friday)

Pre-Market (4:00-9:30 AM)
Gap Assessment
Monitor futures for overnight positioning. Large gaps common.
9:30-10:00 AM ET
SOQ Settlement Window
Index options and futures settle. Opening auction 10x larger than normal (~$28B additional). High volatility.
10:00 AM - 2:00 PM
Midday Pinning
Prices gravitate toward high open interest strikes. Lower volatility window. Best time for defined-risk trades.
2:00-3:00 PM
Pre-Witching Hour
MOC order imbalances published. Volatility starts increasing. Close any open positions.
3:00-4:00 PM ET
"Witching Hour" — DO NOT TRADE ⚠️
31% win rate (worst ever recorded). 365% closing auction increase. Price swings of 1%+ in minutes. Spreads widen unpredictably.
⚠️ Critical Warning
September 2024 example: SPY traded 162M shares (2x average), with 58M in the final hour alone. Stock futures jumped/fell 0.5-1%+ within seconds.
🎯

Trading Strategies

⭐ Highest Edge Strategy: Pre-Expiration Rally

Go long Monday open of witching week, exit Thursday close. Average gain: +0.55% per trade, 65% win rate across 128 backtested trades.

📈 Entry Rules
  • Enter long S&P 500 exposure (SPY, ES futures, or equivalent) at Monday open of witching week
  • Alternative: Enter T-9 (Monday prior week) for full rally capture (+0.82% average)
  • Size position at 70-80% of normal to account for elevated volatility
  • Set stops at 2.5 ATR (wider than normal 2 ATR)
📉 Exit Rules
  • Exit all positions by Thursday 3:30 PM ET — BEFORE Friday
  • If Wednesday shows strong gains (+0.5%+), consider taking partial profits
  • Use limit orders only — never market orders approaching expiration
  • NEVER hold into Friday — negative expected value
⚠️ High Risk Environment
Triple witching Friday has only a 14% win rate since 2021. The recommended strategy is do not trade, or trade with extreme caution and reduced size.
🎯 If You Must Trade
  • Trade only 10:30 AM - 2:00 PM window (midday lull)
  • Reduce position size to 30-50% of normal
  • Use defined-risk strategies only (spreads, not naked positions)
  • Monitor max pain levels — prices gravitate toward them
  • Close ALL positions by 2:30 PM at the latest
🚫 What to Avoid
  • NEVER trade the opening 30 minutes (SOQ settlement chaos)
  • NEVER trade the final hour (3-4 PM "witching hour")
  • NEVER use market orders — slippage is severe
  • NEVER hold expiring options through close
  • NEVER chase moves — reversals are violent

Max Pain Reference

Max pain is the strike price where the most options expire worthless. Prices tend to gravitate toward this level during the day.

// Max Pain Calculation // For each strike price, calculate: Total Pain = Σ (Open Interest × |Strike - Current Price|) // Max Pain = Strike with MINIMUM total pain // Check sources like: maximum-pain.com, opricot.com, or your broker's tools
📉 Post-Witching Weakness Pattern
The week following triple witching has been negative in 14 of 21 years (66%). September's following week is historically the worst — "rarely positive over 30 years and averages greater than 1% declines."
🔄 Reversal Setup Criteria

Watch for these conditions Monday-Tuesday after witching:

  • VIX spike of 15%+ from pre-witching levels
  • S&P declines 1%+ from Thursday close
  • Volume returns to normal levels (hedging complete)
  • Put/call ratio normalizes from elevated levels
📊 Seasonal Variations
March
End of Q1 rebalancing. Watch for window dressing flows.
June
Russell reconstitution week. Small caps most affected.
September
Worst seasonal period. Post-witching week historically terrible.
December
Tax loss harvesting + holiday liquidity. Can be choppy.
💰 Premium Selling Strategy

Timing: Establish positions 1-2 weeks BEFORE witching when IV is elevated.

  • Sell premium 7-14 days out from expiration
  • Close positions by Wednesday of witching week
  • Use defined-risk spreads (iron condors, verticals)
  • DO NOT sell premium directly into expiration day
📅 Calendar Spread Strategy

Setup: Buy longer-dated options, sell expiring options.

  • Benefits from accelerated time decay on short leg
  • Enter 5-7 days before expiration
  • Target strikes near max pain level
  • Close when short leg reaches 80% profit or Thursday EOD

Cross-Market Effects

Cryptocurrency Impact

The "Wall Streetization" of Bitcoin has created tight linkages:

BTC-VIX Correlation
Record 0.88 correlation between Bitcoin implied volatility (BVIV) and VIX in recent periods.
Recent Example
Dec 2024 triple witching: BTC dropped from $97,777 to $92,200 in hours before recovering.
Crypto Expirations
CME BTC/ETH: Last Friday of month. Deribit quarterly: Last Friday of Mar/Jun/Sep/Dec at 08:00 UTC (doesn't align exactly with equity triple witch).
Watch for amplified crypto moves when leveraged traders face liquidations during equity volatility spikes.
📊 Commodities & Bonds
Gold
Positive relationship with VIX — acts as safe haven during triple witching volatility.
Oil
Negative relationship with implied volatility — categorized as riskier asset during uncertainty.
Dollar (DXY)
Tends to strengthen during risk-off moves, creating headwinds for commodities and crypto.
Treasuries
Flight to safety effect. Dec 2023: 10Y yield dropped 11bps to 3.92% around witching.
