The analysis covers 20 years from 2006 through 2025.
The week of July 4th has a long-standing reputation of having light holiday volume with a tendency to drift higher. We tested that view against 20 years of S&P 500 data, measuring close-to-close returns for the Monday-to-Friday week containing the holiday.
The pattern holds, even though a couple of rough summers do a lot of damage pulling the average down.

Thirteen of the twenty holiday weeks closed higher, a 65% positive rate. The median return was +1.26%. The average return was lower at +0.44%, largely because two years dragged the mean down: -5.03% in 2010 and -2.45% in 2009. Removing those two outliers lifts the average and makes the upward lean more consistent.
The most recent decade has been stronger. From 2016 through 2025 the holiday week averaged +1.47% and finished positive in nine of ten years. The only decline in that stretch was -1.16% in 2023.
