How Much Impact Does the President Have on Stocks?
October 2, 2020
The anticipation building up to elections often brings with it questions about how financial markets will respond. But the outcome of an election is only one of many inputs to the market. Our interactive exhibit examines market and economic data for nearly 100 years of US presidential terms and shows a consistent upward march for US equities regardless of the administration in place. This is an important lesson on the benefits of a long-term investment approach.
