What Is Quadruple Witching?

Quadruple witching refers to the third Friday of every March, June, September and December. On these days, derivatives (e.g. market index futures, options futures, stock options, stock futures) expire, usually resulting in increased volatility.

How Does Quadruple Witching Work?

Although futures and options generally expire on the third Friday of every month, quadruple witching only occurs four times per year. 

The last hour of these trading days (between 3:00 to 4:00 p.m. EST)  is referred to as the quadruple witching hour.

On quadruple witching days – and especially during quadruple witching hours – it’s common for investors to try and unwind their futures and options positions before the contracts expire. This often includes repurchasing contracts and closing out position market capitalizations.

Where Does the Phrase “Quad Witching” Come from?

A “witching hour” is historically known as a time for bad luck. Because all of these derivatives expire on the same date, quadruple witching days are named for their volatility (i.e. “bad luck”).
