Quadruple witching refers to the simultaneous expiration of stock index futures, stock index options, stock options, and single stock futures on the same day.

This significant event occurs four times a year, typically on the third Friday of March, June, September, and December.

Financial markets experience increased trading volume and potential market volatility during these periods as market participants rush to close out or roll over their expiring derivative positions.

The concept of quadruple witching evolved from triple witching, which only involved three types of expiring contracts.

The addition of single-stock futures in 2002 transformed it into quadruple witching, although single-stock futures stopped trading in the United States in 2020.

Despite this, the term "quadruple witching" is still commonly used in the financial world, though "triple witching" is now more accurate for U.S. markets.

Understanding Quadruple Witching

Quadruple witching involves the concurrent expiration of four types of derivative contracts:

1. Stock index futures: Contracts based on the future value of a stock market index.

2. Stock index options: Options contracts on stock market indices.

3. Stock options: Options contracts on individual stocks.

4. Single stock futures: Futures contracts on individual stocks (no longer traded in the U.S.).

The main difference between quadruple and triple witching is the inclusion of single stock futures.

Triple witching, which is now more common in the United States, only involves the expiration of stock index futures, stock index options, and stock options contracts.

Key players during quadruple witching include:

• Market makers: Provide liquidity and facilitate trades.

• Institutional investors: Manage large portfolios and may need to adjust positions.

• Portfolio managers: Rebalance portfolios to align with benchmark indices.

• Hedge funds: May exploit price discrepancies or adjust hedging strategies.

• Retail traders: Individual investors who may be affected by or seek to profit from market movements.

These market participants contribute to the increased trading activity and potential market volatility associated with quadruple witching events.

Market Impact of Quadruple Witching

Increased trading volume is a hallmark of quadruple witching days.

On average, trading volume can be 50% to 100% higher than on regular trading days.

This surge in activity is primarily due to the closing, rolling over, or offsetting of derivative positions.

Volatility patterns during quadruple witching can vary. While increased volatility is often expected, it's not guaranteed.

Some quadruple witching days may see relatively calm markets, while others experience significant price swings.

Price movements and trends during quadruple witching can be unpredictable.

Some common observations include:

• Increased intraday volatility

• Potential for price reversals near the close of trading

• Temporary distortions in the relationship between derivatives and underlying assets

The impact on specific market sectors can differ.

Sectors with a high concentration of stocks with large open interest in options or futures may experience more pronounced effects.

Technology and financial sectors often see increased activity due to their weight in major indices and popularity among options traders.

It's important to note that the effects of quadruple witching are typically short-lived, with markets often returning to normal patterns within a few days following the event.

Long-term investors should be aware of these potential market fluctuations but may not need to take specific action unless it aligns with their overall investment strategy.

The "Witching Hour"

The "witching hour" refers to the final hour of trading on quadruple witching days, typically from 3:00 PM to 4:00 PM Eastern Time.

This period is significant because it's when much of the increased trading activity associated with quadruple witching occurs.

During the witching hour, traders and investors scramble to close out or roll over their expiring derivative positions.

This can lead to:

• Sudden spikes in trading volume

• Increased price volatility

• Potential for large block trades

• Rapid shifts in order flow

Last hour trading dynamics often include:

• Heightened urgency among market participants

• Increased algorithmic trading activity

• Potential for short-term price dislocations

Historical examples of notable witching hours include:

• June 19, 2020: The S&P 500 saw significant volatility in the final hour, with a 0.5% swing in the last 30 minutes of trading.

• March 20, 2015: A surge in volume led to the second-highest trading day of that year, with over 10.8 billion shares changing hands.

While the witching hour can present opportunities for some traders, it also carries increased risks due to the potential for rapid price movements and reduced liquidity.

Investors should be cautious and consider implementing stop-loss orders to manage risk during this volatile period.

It's crucial to understand that trading during this time is not suitable for all investors and should only be considered by those with a high risk tolerance and a thorough understanding of the market dynamics at play.

Quadruple Witching vs. Regular Trading Days

Comparative analysis of volume shows that quadruple witching days consistently have higher trading volumes than regular trading days.

On average, volume can be 50% to 100% higher, with some instances seeing even greater increases.

Volatility differences between quadruple witching and regular trading days can vary:

• Intraday volatility is often higher on quadruple witching days, especially during the last hour of trading.

• Overall daily volatility may not always be significantly different from regular trading days.

• The VIX (Volatility Index) may show elevated levels leading up to and during quadruple witching days.

Price action patterns on quadruple witching days can differ from regular trading days:

• More frequent and larger price swings, particularly in the last hour of trading.

• Potential for price reversals or "pinning" near option strike prices.

• Temporary disconnects between derivative prices and underlying asset prices.

• Increased likelihood of gap openings on the following trading day.

It's important to note that while these patterns are common, they are not guaranteed.

Market conditions, economic news, and other factors can influence how quadruple witching days compare to regular trading days.

Traders and investors should be aware of these differences when planning their strategies around quadruple witching events.

However, it's crucial to remember that past performance does not guarantee future results, and all trading carries inherent risks.

Strategies for Trading During Quadruple Witching

Risk management techniques for quadruple witching include:

• Setting tighter stop-loss orders to protect against increased volatility.

• Reducing position sizes to limit exposure to potential price swings.

• Using options strategies like straddles or iron condors to potentially profit from volatility.

• Consider implementing option strategies that manage risk during volatile periods like quadruple witching.

Arbitrage opportunities may arise due to temporary price discrepancies:

• Index arbitrage between futures and underlying stocks.

• Options-futures arbitrage.

• Cross-market arbitrage between related instruments.

Hedging strategies to consider:

Quadruple Witching and Options

Impact on options pricing:

• Implied volatility often increases leading up to quadruple witching, affecting option premiums.

• Time decay accelerates for expiring options, potentially creating opportunities for option sellers.

• Bid-ask spreads may widen, especially for less liquid options.

Strategies for options traders during quadruple witching:

1. Straddles and strangles to capitalize on potential volatility.

2. Calendar spreads to profit from differences in implied volatility across expiration dates.

3. Iron condors or iron butterflies to take advantage of potentially inflated option premiums.

4. Rolling strategies to extend positions beyond the current expiration.

Pin risk and how to manage it:

Pin risk occurs when the underlying asset price closes near an option's strike price at expiration, making it unclear whether the option will be exercised.

To manage pin risk:

• Close out at-risk positions before expiration.

• Use limit orders to exit positions, as market orders may be risky during volatile periods.

• Consider using European-style options, which can only be exercised at expiration.

• Monitor positions closely and be prepared to make quick decisions.

Options traders should be particularly vigilant during quadruple witching due to the potential for increased volatility and unusual price movements in the underlying assets.

It's crucial to understand the risks associated with options trading and to adhere to applicable risk disclosures provided by brokers and exchanges.
