The USA500 is trading at around 4,316 on Tuesday morning.
Concerns over a potential shutdown kept U.S. stock indexes trading lower over the past week, although a bulk of this weakness was also driven by fears of a hawkish Federal Reserve. The S&P 500 is trading down 2.7% over the past seven days.
But while a shutdown is expected to provide more headwinds to the U.S. economy- especially as it grapples with higher-for-longer interest rates and sticky inflation, historical data shows that stock markets have performed well during the three shutdowns over the past 10 years.
