Stock Market Today: June 20, 2025 – Triple Witching Day Creates Historic $6.5 Trillion Expiry Event

By / / Market Update
Bottom Line Up Front: U.S. markets opened modestly higher on this triple witching Friday, with the S&P 500 gaining 0.4% amid diplomatic progress in Middle East tensions and Fed dovish signals. Today’s $6.5 trillion derivatives expiration could amplify volatility, particularly during the final trading hour.

Triple Witching: The $6.5 Trillion Expiry Event

Today marks one of the most significant trading events of the quarter: triple witching day. Investors are bracing for $6.5 trillion of notional US options expiring on Friday, in a move that could free stocks to swing more wildly than the subdued changes seen in recent weeks.

Triple witching refers to the simultaneous expiration of three critical derivative instruments:

  • Stock options – Monthly contracts on individual stocks and ETFs
  • Stock index futures – Contracts based on major indices like the S&P 500
  • Stock index options – Options tied to broad market benchmarks
⚠️ Volatility Alert: The final hour of trading (3-4 PM ET), known as the “witching hour,” typically sees the most intense price movements as traders rush to close, roll over, or exercise positions.

📊 Market Snapshot – June 20, 2025

  • S&P 500   +0.4% in early trading

📈 Triple Witching Impact Analysis

Triple witching happens four times a year (or once a quarter) on the third Fridays of March, June, September, and December. Historical patterns show significant market implications:

Volume and Volatility Expectations

Triple witching day is consistently one of the most heavily traded days each year. For example, in 2021, S&P 500’s average daily volume was 2.1 million. However, the average volume almost doubled to 4 million on the four triple witching trading days.

Historical Market Behavior

  • Intraday Swings: SPX’s daily range expanded nearly 7% on triple witching days, and the average percentage return was -0.72% lower than the daily average
  • Final Hour Intensity: Most dramatic price movements typically occur during the 3-4 PM ET “witching hour”
  • Sector Rotation: High-beta and options-heavy stocks experience amplified movements

🏢 Corporate Earnings and Individual Stock Movers

Notable Pre-Market Movers

  • Accenture (ACN): Stock is down more than 4% after the global consultancy company reported new bookings decreased 6% to $19.7 billion
  • CarMax (KMX): Stock climbed 11% in premarket trading after the used car dealer’s first quarter earnings and revenue beat Wall Street expectations
  • GMS Inc: Stock was up 23% after the Wall Street Journal reported that Home Depot has made an offer to acquire GMS, a building-products distribution company
  • Tesla (TSLA): Stock rose over 1% before the bell following reports that the EV maker had signed a $557 million energy storage station deal

🎯 Trading Strategy Considerations

For Active Traders:

  • Reduced Position Sizes: Consider smaller trades due to increased volatility potential
  • Time Management: Be especially cautious during the 3-4 PM ET witching hour
  • Options Focus: Monitor high-volume options chains for unusual activity
  • Index Exposure: Major indices may experience heightened sensitivity to news flow

For Long-term Investors:

  • Opportunity Window: Potential temporary price dislocations may create entry points
  • Portfolio Review: Good time to assess overall market exposure and risk management
  • Patience Required: Avoid making major decisions based solely on triple witching volatility

As we navigate this triple witching Friday, several factors will determine market direction:

Critical Monitoring Points

  • S&P 500: Hovering near record highs with forward P/E around 22x
  • VIX (Fear Gauge): Monitor for spikes above 20-25 indicating stress
  • Treasury Yields: 10-year at 4.44% remains key resistance level
  • Dollar Strength: Impact on multinational earnings and commodities
