Investors kickoff the week awaiting more developments on President Trump’s trade deals and the decision on interest rates by the Federal Reserve out Wednesday. Optimism is improving after the S&P 500 notched the longest winning streak in 20 years last week.

US stocks retreated from a historic run of gains on Monday as President Trump's new tariff threat revived trade war worries in the wait for a Federal Reserve policy decision. The US dollar (DX=F) also lost ground as Wall Street gauges whether recent confidence that Trump has moved to a dealmaking phase is misplaced.

It felt much longer, but the U.S. stock market needed just a few weeks to roar all the way back to where it was on President Donald Trump’s “Liberation Day.”
