Quadruple witching day, also known as the four witching days, is the third Friday of March, June, September, and December every year in the USA stock market. It is the expiry settlement day for derivative financial products, and the last trading hour of that day is called the quadruple witching hour, which is from 3-4 pm in New York time.
Due to the recent decline in stock trends, this quadruple witching day is the largest short position settlement in US history. It is expected that the short sellers will continue to dump stocks to make big profits. The good news is that after the noon settlement, the downward pressure from short selling will disappear, and the short sellers will start to rebuild positions, expecting a rebound in the second half of the day.
