Triple witching hour

Triple witching hour is the last hour of the stock market trading session (3:00-4:00 P.M., New York City local Time) on the third Friday of every March, June, September, and December. Those days are the expiration of three kinds of securities:

The simultaneous expirations generally increases the trading volume of options, futures and the underlying stocks, and occasionally increases volatility of prices of related securities.

On those same days single-stock futures also expire, so that the final hour is sometimes referred to as the quadruple witching hour.[1]

Concept and usage

The term "triple witching" refers to the extra volatility resulting from the expiration dates of the three financing instruments, and is based on the witching hour denoting the active time for witches.

It is used often and is considered industry jargon, along with the term "Freaky Friday".[2]

This daylong event, which is sometimes referred to as “Freaky Friday,” is an important day for short-term investors because the markets tend to be turbulent and unpredictable, shifting erratically as traders attempt to offset their orders before the closing bell rings.
