The impact of US presidential elections on markets

In a world of constant change and uncertainty, there’s one thing we can be certain of in 2024 and that is that there’s going to be a US presidential election in November

What happens to the markets in US presidential election years? Having a look at the past, an election year normally brings an overall positive year for US equities. But it’s certainly not guaranteed. As research from Morgan Stanley shows, on average, the S&P 500 increases 11.28% in an election year. At the extremes, however, you find a 43.6% increase in 1928 and a 37% decrease in 2008. 1928 and 2008, of course, are very significant years; the former being the height of the boom, which preceded the Wall Street Crash of 1929 and the latter the year of the Great Financial Crisis. What this also tells us is that broader economic factors can have a greater impact on markets and investments than the election itself.

Things to look out for

When thinking about how a US presidential election might impact your portfolio, both this year and into the future, there are a few things you should look out for. The first, perhaps obviously, is policy differences. Different candidates will have different priorities when it comes to major policy areas like healthcare, energy and security. These policy differences can have a material impact over the four years of a presidential term on the performance of certain sectors or particular equities. It’s important, therefore, to be aware of them and to plan accordingly.

Another important factor to keep in mind is the scale of a victory. The American system needs some level of agreement between the President and Congress to function and in this respect the results of the elections for the House of Representatives and the Senate, which will happen on the same day as the presidential election, will be just as important. Should one party win all three elections, then there is a much greater chance of the President’s policies being put in place. If not, expect greater uncertainty in terms of the policy agenda.

In addition to the above, also keep in mind that decisions taken before the election will have consequences after it. It’s inevitable that during an election year, politicians are reluctant to pursue action which might cost them votes. In an already challenging economic and geo-political context, decisions which are, or are not, taken in the run up to November might end up being reversed fairly quickly once 2025 arrives.
