Triple witching sounds like something from a horror movie, but it’s actually a financial term. Options and
derivatives traders know this phenomenon well because it’s the day when three different types of contracts expire.
It happens only once a quarter and can cause wild swings in
volatility, as large institutional traders roll over futures contracts to free up cash.
Doing so creates a ton of increased volume—sometimes 50% higher than average, especially in the last trading hour of the day—but
individual investors needn’t feel spooked. In fact, some might even view this
volatility as a profit-making opportunity.
