It has barely mattered which party held the White House. Midterms under both delivered almost the same average gain.

Across the nine midterms from 1990 through 2022, the S&P 500 rose an average of 14.0 percent in the 12 months after election day. The weakest year followed 2010, a gain of 2.1 percent, and the best followed 1994, at 25.9 percent.

Under Republican presidents the average was 14.6 percent across four cycles, against 13.6 percent across five under Democrats. On November 4, the day after this year's vote, the index rose 1.6 percent to close at 7,688.62.

Nine cycles is a small sample, and none of them ended a year lower.
