Halloween brings out ghouls, goblins and ghosts, but four times a year, the U.S. markets bring out the witches – or witching. Quad witching to be exact.
Quadruple or “Quad” (and triple and double) witching is aptly named for the volatility and havoc inherent in four derivative products expiring on the same day, which occurs four times a year. As the end of each quarter approaches, traders can anticipate higher trading volume and volatility when four classes of contracts simultaneously expire.
The expiration of options contracts, index options, single stock futures and future indexes ushers in heavy trading as contracts that are profitable settle automatically with offsetting trades.
The third Friday of March, June, September and December are designated quad witching days each year. Last month, we witnessed just how quad witching influences market fluctuations as approximately 750 billion single stock options matured at one time. While this phenomenon doesn’t always lead to serious volatility, it certainly impacts the markets.
- Depending on the market trend, quad witching can exacerbate either bullish or bearish sentiment.
- Investors should not attempt to time the market during quad witching periods, as there can be significant intra-day volatility associated with the expirations. As the father of value investing, Benjamin Graham, once noted, “In the short run, the market is a voting machine; but in the long run, it is a weighing machine.”
The final quad witching event of 2021 will occur on Dec. 17, 2021. Watch for market movement starting typically a week prior, where historically the fluctuations are fairly positive. As for the witching day itself, we often see the increased volatility is paired with some market declines.
