I’ve noted a number of times that Op-ex week in general is pretty bullish. March, April, October, and December it has been especially so. S&P 500 options began trading in mid-1983. The table below is one I have showed in March each of the last several years. It goes back to 1984 and shows op-ex week performance broken down by month. All statistics are updated. While December has been more reliable, March op-ex week has seen the most in total gains. Traders may want to keep this in mind this week, and refer back to the table in future months.
