NEW YORK (AP) — U.S. stocks climbed again on Monday as Wall Street’s wild roller-coaster ride veers back upward.

The S&P 500 rose 0.6% for a second straight gain after it fell 10% below its record late last week. The Dow Jones Industrial Average climbed 353 points, or 0.9%, and the Nasdaq composite added 0.3%.

More big swings could be ahead, with a decision by the Federal Reserve on interest rates coming later in the week and worries continuing about President Donald Trump’s trade war.

Stocks have been mostly tumbling on worries that Trump’s rat -a- tat announcements on tariffs and other policies are creating so much uncertainty that they’ll push U.S. households and businesses to freeze their spending, which would hurt the economy. Surveys have shown sharp drops in confidence, and some companies are already warning about changes in behavior from their customers.
