The chart above illustrates stock market performance 12 months before and after an election, compared to non-election years and typical seasonality (source: Barclays). During election years (dark blue), markets tend to rally in the months leading up to the election, stabilize, and then push higher 3-9 months afterward. This aligns with the idea that markets dislike uncertainty, and once the election is over, participants can better navigate the environment with more clarity.

While there are many ways to interpret this data, choosing the timeframe can provide a variety of outputs. Since 1928, markets have tended to perform well in the four months following a Republican win, whereas after a Democratic victory, markets generally see stronger performance from the election date through the following 12 months.

Lastly, when comparing small caps to large caps, it’s clear that small caps tend to outperform during election years—particularly six months and one year after Election Day. This is especially relevant for our portfolio, as we believe the best opportunities lie within mid- and small-cap companies today, ranging from $1 to $15 billion in size. Historically, these companies have delivered a 20.1% return in the 12 months following an election.
