Since the S&P index futures began trading on April 21, 1982, stock options, index options as well as index futures all expire at the same time four times each year in March, June, September [20 - Fri], and December. September’s quarterly option expiration week has been up 54.8% of the time for S&P 500 since 1982. DJIA and NASDAQ have slightly weaker track records with gains 52.4% of the time and 52.4% respectively.
However, the week has suffered several sizable losses. The worst loss followed the September 11 terrorist attacks in 2001. In the last twenty-one years, S&P 500 and NASDAQ are tied for best record during September’s quarterly option expiration week, up thirteen times, but NASDAQ has been down the last six straight. Friday had been firm with all three indices advancing every year 2004 to 2011, but S&P 500 has been down 11 of the last 12 and NASDAQ has been down 10 of the last 12 since.
The week after September options expiration week, has a dreadful history of declines most notably since 1990. The week after September quarterly options expiration week has been a nearly constant source of pain with only a few meaningful exceptions over the past 34 years.

In 2022 DJIA and S&P 500 declined over 4% while NASDAQ fell 5.07%.
Full stats are the sea-of-red in the tables here. Average losses since 1990 are even worse; DJIA –1.09%, S&P 500 –1.06%, NASDAQ –1.06%. End-of-Q3 portfolio restructuring is the most likely explanation for this trend as managers trim summer holdings and position for the fourth quarter.
