US economy doesn’t radically change
Investors are often concerned that elected officials will radically re-engineer the economy. In fact, the composition of the US economy has been consistent for decades. Even single-party rule periods didn’t result in significant change. The percentage of “substantive” bills by Congressional term hasn’t increased when one party controlled the executive and legislative branches.5
Neither party is fiscally responsible
Federal spending has outpaced taxes and other sources of government revenue in most years and across most administrations.6 No party can claim fiscal responsibility. It hasn’t been a significant issue for a variety of reasons, including the US having the world’s largest reserve currency and nominal economic growth outpacing the interest expense as a percent of gross domestic product (GDP).
Monetary policy matters more
For all the focus on the executive branch, I’d argue that it’s monetary policy that matters more. The old adage holds true: Don’t fight the Fed. Historically, presidents have been hurt or helped by monetary policy conditions. For instance, both Presidents Reagan and Clinton benefited from consistently falling interest rates. Both Presidents George H.W. Bush and George W. Bush were hurt by Fed tightening, an inverted yield curve, and a recession. President Obama benefitted from a benign rate environment (minus a brief moment in 2015-2016) during his term, and President Trump was the unfortunate recipient of tighter policy during his first two years.7
President’s popularity doesn’t matter
Investors don’t have to love what is going on in Washington, DC, to prosper in the markets. In fact, the S&P 500 historically performed the best when the president’s approval rating was in the low range — between 35 and 50.8 That means the market had delivered some of its best returns during periods when half or more of the country didn’t approve of the job the current administration was doing! Still, it’s hard to discern any direct relationship between a president’s popularity, the health of the US economy, and the performance of financial markets.
