It’s almost Election Day in the US once again. For those who need a brief civics refresher, every two years the full US House of Representatives and one-third of the Senate are up for reelection. While the outcomes of the elections are uncertain, one thing we can count on is that plenty of opinions and prognostications will be floated in the days to come. In financial circles, this will almost assuredly include any potential for perceived impact on markets. But should long-term investors focus on midterm elections?

We would caution investors against making short-term changes to a long-term plan to try to profit or avoid losses from changes in the political winds. For context, it is helpful to think of markets as a powerful information-processing machine. The combined impact of millions of investors placing billions of dollars’ worth of trades each day results in market prices that incorporate the aggregate expectations of those investors. This makes outguessing market prices consistently very difficult.1  While surprises can and do happen in elections, the surprises don’t always lead to clear-cut outcomes for investors.

The 2016 presidential election serves as a recent example of this. There were a variety of opinions about how the election would impact markets, but many articles at the time posited that stocks would fall if Trump were elected.2  The day following President Trump’s win, however, the S&P 500 Index closed 1.1% higher. So even if an investor would have correctly predicted the election outcome (which was not apparent in pre-election polling), there is no guarantee that they would have predicted the correct directional move, especially given the narrative at the time.
