Stock market today, a quadruple witching day may add more volatility for stock trading
Today, March 20, 2020, is a quadruple witching day. This quadruple witching term “refers to a date on which derivatives of stock index futures, stock index options, stock options, and single stock futures expire simultaneously.”

Most probably there could be an increased trading volume day today, and during the first 3 hours of trading, all major stock indices and several stocks traded with elevated volatility, as an early stock market rally faded as of 12:12 PM, Friday, March 20, 2020, Eastern Time (ET).
