Observations on the US Midterm Elections

| November 07, 2018

Political ads are finally over, for now, and the US midterm elections on November 6th resulted in a divided government—the widely expected outcome—with the Democratic Party gaining control of the House of Representatives while the Republican Party maintained their majority in the Senate. We believe the markets were largely priced for this outcome and therefore expect limited effect on market volatility. In general, the markets care more about fundamentals and policies than politics, with markets showing greater resilience towards political events or rhetoric that produce little action. With that being said, looking back historically, there is a compelling pattern of stock market trends that gives us a reason to be optimistic for the next quarter and into 2019. Below are 5 charts relating to midterm year stock performance history, as well as specific data on average returns after a split congress outcome. 


5 Midterm Charts to Know
