Editing Triple witching hour

{{Short description|Term in stock market trading}}
'''Triple witching hour''' is the last hour of the [[stock market]] trading session (3:00–4:00{{nbsp}}p.m., [[Eastern Time|New York time]]) on the third Friday of every March, June, September, and December.  Those days are the expiration of three kinds of securities:
* [[Stock market index future]]s;
* [[Stock market index option]]s;
* [[Stock option]]s.

The simultaneous expirations generally increases the trading volume of options, futures, and their underlying stocks, occasionally increasing the [[Volatility (finance)|volatility]] of prices of related securities.

On those same days [[single-stock future]]s also expire, so that the final hour is sometimes referred to as the '''quadruple witching''' hour.<ref>{{cite web|title=Quadruple Witching |url=http://www.investopedia.com/terms/q/quadruplewitching.asp |publisher=Investopedia}}</ref>

==Concept and usage==
The term "triple witching" refers to the extra volatility resulting from the [[Expiration (options)|expiration dates]] of the three financing instruments, and is based on the ''[[witching hour]]'' denoting the active time for [[witch]]es.  

It is used often and is considered industry [[jargon]], along with the synonym, ''Freaky Friday''.<ref>{{cite web |url=https://hitandruncandlesticks.com/what-is-triple-witching/ |title=What is triple witching? |last1=Saddler |first1=Rick |date=June 25, 2014 |website=Hit & Run Candlesticks |publisher= |access-date=July 1, 2016 |quote=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.}}</ref>
