Wall Street ends lower as ruling on Trump tariffs raises concerns

Wall Street started off September on a sharply lower note on Tuesday as investors weighed the future of President Donald Trump's tariffs after a federal appeals court ruled most of his sweeping tariffs illegal. A divided U.S. appeals court made the ruling on Friday, but allowed for the levies to be in place until October 14. Trump on Tuesday said his administration will ask the Supreme Court for an expedited ruling on the tariffs.

The appeals court ruling rattled investors after the long Labor Day holiday weekend, with September traditionally a weak month for equities. The Cboe Volatility Index - Wall Street's fear gauge - rose, but the major stock indexes ended off their worst levels of the day.

With the ruling, "the question becomes, 'Has the Trump administration alienated our trading partners as well as given up the revenue from tariffs?' That's what's plaguing markets," said Oliver Pursche, senior vice president and adviser for Wealthspire Advisors in Westport, Connecticut.

"By the same token, it's too early to call this the beginning of a great correction," he said. "At the end of the day, we all know that August-September tend to be more volatile and a little more challenging for investors before we get into the fourth quarter, which tends to be a pretty solid one." Data going back decades shows that, on average, September is the worst month for U.S. stocks, and some investors are bracing for another bumpy ride this year. In addition, investors are anxious to see the monthly U.S. payrolls report, due on Friday, and whether weak U.S. job growth continued for a fourth month in August.

Real estate fell 1.7% and had among the biggest S&P 500 sector declines on the day, with U.S. 30-year Treasury yields on Tuesday climbing to their highest levels since mid-July.
