ChatGPT:
Quadruple witching refers to the expiration of four different types of financial instruments on the same day: stock options, stock index futures, stock index options, and single stock futures. This phenomenon typically occurs on the third Friday of March, June, September, and December each year. It's a significant event in financial markets due to the potential increase in trading volume and volatility as traders and investors adjust their positions.
