NEW YORK (AP) — Much like its wild month of April, a scary Wednesday for Wall Street found a gentler ending as U.S. stocks stormed back from steep early losses to continue their manic swings amid uncertainty about what President Donald Trump’s trade war will do to the economy.

The S&P 500 rose 0.1% to extend its winning streak to a seventh day. The Dow Jones Industrial Average added 141 points, or 0.3%, while the Nasdaq composite edged down by 0.1%.

It was a stunning reversal after the S&P 500 dropped as much as 2.3% and the Dow fell 780 points in early trading. Stocks initially tumbled after a report suggested the U.S. economy may have shrunk at the start of the year, falling well short of economists’ expectations, in a sharp turnaround from the economy’s solid growth at the end of last year.

Importers rushed to bring products into the country before tariffs could raise their prices, which helped drag on the country’s overall gross domestic product.

Such data raised the threat of a worst-case scenario called “stagflation,” one where the economy stagnates yet inflation remains high. Economists fear it because the Federal Reserve has no good tools to fix both problems at the same time. If the Fed were to try to help one problem by adjusting interest rates, it would likely make the other worse.

“Even if today’s weak GDP may have partially reflected companies trying to get ahead of tariffs, it was still a stagflation warning shot over the bow of the economy,” according to Ellen Zentner, chief economic strategist for Morgan Stanley Wealth Management.

But some better news came later in the day when a report said the measure of inflation that the Fed likes to use slowed in March. Inflation decelerated to 2.3%, closer to the Fed’s goal of 2%, from February’s reading of 2.7%. Stocks began paring their losses almost immediately after the report.

If inflation keeps trending lower, it would give the Fed more leeway to cut interest rates in order to juice the economy. Expectations are building for the Fed to cut its main interest rate at least four times by the end of this year, according to data from CME Group, though it likely won’t begin at its next meeting next week.

Much of Wednesday’s economic data raised concerns about a weakening economy. A report on the job market from ADP suggested employers outside the government may have hired far fewer workers in April than economists expected, less than half.

It’s discouraging because a relatively solid job market has been one of the linchpins keeping the U.S. economy stable. A more comprehensive report on the job market from the U.S. government will arrive Friday.
