NEW YORK>> Wall Street hit the brakes on its big rally Wednesday following disappointing profit reports from companies and warnings that the market had simply gone too far, too fast.

The S&P 500 slumped 1.5% for its worst loss since beginning a monster-sized rally shortly before Halloween. The Dow Jones Industrial Average dropped 475 points, or 1.3%, from its record high, while the Nasdaq composite sank 1.5%

FedEx tumbled 12.1% for one of the market’s biggest losses after reporting weaker revenue and profit for the latest quarter than analysts expected. It also now expects its revenue for its full fiscal year to fall from year-earlier levels, rather than being roughly flat, because of pressures on demand.

The package delivery company pumps commerce around the world, and its signal for potentially weaker demand could dim the hope that’s fueled Wall Street’s recent rally: that the Federal Reserve can pull off a perfect landing for the economy by slowing it enough to stifle high inflation but not so much that it causes a recession.

Winnebago Industries also fell short of analysts’ profit expectations for the latest quarter. The maker of motorhomes and other recreational products said it sold fewer units than a year earlier because of “market conditions” and had to offer higher discounts. Its stock dropped 5.6%.

General Mills, which sells Progresso soup and Yoplait yogurt, reported stronger profit for the latest quarter than expected, but its revenue fell short as a recovery in its sales volume was slower than expected. The company said a key sales measure may now fall for its full fiscal year because of “a more cautious consumer economic outlook” and other factors. Its stock fell 3.6%.

Still, a pair of reports showed the U.S. economy may be in stronger overall shape than expected. Both confidence among consumers in December and sales of previously occupied homes in November improved more than economists had expected.

Encouraging signs that inflation is cooling globally also continue to pile up. In the United Kingdom, inflation in November unexpectedly slowed to 3.9% from October’s 4.6% rate, reaching its lowest level since 2021.

Easing rises in prices are raising hopes that central banks around the world can pivot in 2024 from their campaigns to hike interest rates sharply, which were meant to get inflation under control.

For the Federal Reserve in particular, the general expectation is for its main interest rate to fall by at least 1.50 percentage points in 2024 from its current range of 5.25% to 5.50%, which is its highest level in more than two decades.

Treasury yields have been tumbling since late October on such hopes, and they fell again following the U.K. inflation report.

The yield on the 10-year Treasury dropped to 3.85% from 3.93% late Tuesday. It had been above 5% in October, at its highest level since 2007 and putting harsh downward pressure on the stock market.

Lower interest rates and yields not only help the economy grow by making borrowing less expensive, they also boost prices for investments and relax the pressure on the overall financial system.
