How are markets affected?
Before we explore what can be affected by the outcome of the US election, let’s take a quick look at what the history books can teach us. The good news is US companies have enjoyed average returns of 9.1% during election years, according to research by Fidelity*.
However, Denise Chisholm, Fidelity’s director of quantitative market strategy, pointed out the presidential election isn’t a notably market-moving event. “The election cycle is usually not the dominant theme of the market,” she explained. The economic backdrop at election time tends to matter more than who actually wins, according to a study by Shawn L. Snyder, global investment strategist at JPMorgan**.
Ultimately, the political and economic policies championed by the incoming President could also have an impact – positively or negatively – on the outlook for various sectors. For example, they may wish to increase tariffs in certain areas or even go to war. In any scenario there are likely to be corporate winners and losers.

Potential impact of tariffs
The Republican Party may take a tougher stance on tariffs and immigration, according to JPMorgan. It highlighted Trump’s suggestion of a broad 60% tariff on all Chinese goods entering the US, along with an across-the-board levy of 10% on products from elsewhere**.
“While a boost to US competitiveness may appeal to many, it could also come at a cost to American consumers,” it warned. “Bloomberg estimates suggest that Trump’s proposed plans would leave consumer prices 2.5% higher and GDP 0.5% lower after two years.”
Of course, the economic impact on the US could be greater if tariffs result in a tit-for-tat retaliation with its key trading partners. “Regardless of who wins the election, it seems that a more aggressive protectionist stance is likely to be adopted,” it added.
Avoid second guessing
While there are clear policy differences between the parties, JPMorgan’s analysis urges “extreme caution” for investors planning to position portfolios around an assumed result. “Even if an investor felt certain of the result today, what politicians say they will do in an election campaign and what they eventually can enact are often quite different,” it stated.
It’s also worth considering that many other factors will drive markets, aside from the election outcome and the future direction of policy. “What is happening in the economy tends to be much more important for markets than what is happening in the White House,” they concluded.
