In the world of finance, there exists a notable day that falls on the third Friday of March, June, September, and December. On this day, traders and investors alike brace themselves for the expiration of index futures, index future options, and certain stock options. This phenomenon, known as Triple Witching Friday, is infamous for its high volatility in the market. As a knowledgeable professor, I urge you to keep this date in mind and be prepared for potential fluctuations in the financial landscape.
