Stocks Slump As Quad Witching Day Approaches


Sep. 20 2021, Published 5:16 a.m. ET

With a third quadruple event on Sep. 17, stocks of all kinds were bearish in the week prior. Quadruple days are the third Friday of March, June, September, and December, near the end of each calendar quarter. Various contracts in the market, including stock-index futures, stock-index options, stock options, and single-stock futures, tend to expire on those days. That expiration leads to a large amount of volatility in the market, similar to how there’s an increase in volatility on NFP (non-farm payroll) days.

As contracts expire on those days, investors are wary. It can be difficult to analyze charts and make entries into certain investments or trades. Some see quadruple witching days as buying opportunities, as certain stocks fall on those days.

Are quad witching events good or bad?

Trading futures on options on those days can be hazardous if you’re not experienced. However, seasoned traders might enter a new contract right after or on the day of a quad witching event. Some may even hedge against what's trending, hoping for a reversal of what happened to a specific stock. Markets are commonly bearish on these days, and can wipe out weekly or even monthly gains that were made.

There are other factors that can worsen the impact of quadruple witching days, such as COVID-19 worries, consumer spending, unemployment claims, policies, interest rates, and more. The week after the quadruple witching day finishes, stocks tend to be a lot less volatile and return to normal.

What’s to come for the next quadruple witching day?

With the last quad witching day of the year still to come, indexes, stocks, and commodities could see volatility. If you’re a long-term trader, you could still see gains—the Nasdaq, Dow Jones, and S&P have been bullish since the beginning of this year compared with other years. However, if you’re more into trading short-term contracts, you could see bearish activity.
