Wall Street lost ground on Monday, dragged down by financials as underwhelming bank earnings curbed investor enthusiasm.
But while all three major US stock indexes edged lower, the S&P 500 remained within a percent of its record high.
Following a January-March rally that marked the US stock market's best quarterly performance in nearly a decade, stocks had been in a holding pattern in April ahead of first-quarter reporting season.
Goldman Sachs dipped 3.8 percent after the investment bank's first-quarter revenue came in below analyst expectations.
Citigroup Inc posted higher-than-expected earnings as cost-cutting offset falling revenues. Its shares ended the session nominally lower, dropping 0.1 percent.
"We're coming off of a strong week last week," said Joseph Sroka, chief investment officer at NovaPoint in Atlanta. "So any bad news or earnings reports this week, such as we saw with Goldman and Citigroup, is going to take away some of that momentum."
With first-quarter reporting season shifting into high gear, analysts now see S&P 500 companies posting a 2.1 percent year-on-year decline in profits. While an improvement over recent estimates, it would still mark the first annual decline in earnings since 2016.
"We'll get a clearer sense as we move through the week," Sroka added. "As we move into other sectors we'll get a clearer picture of corporate earnings and the economy."
Bank of America Co, Morgan Stanley, Netflix Inc, Johnson & Johnson, Textron Inc, Honeywell International Inc, Schlumberger NV and American Express Co are among the closely-watched earnings expected this holiday-shortened week.
Aside from earnings, "we still have to be watchful for global geopolitical events such as the US-China trade discussion," warned Sam Stovall, chief investment strategist of CFRA Research in New York.
Sources said US negotiators have softened their demands that China curbs industrial subsidies as a condition for a trade deal, marking a retreat from a core US objective.
"It's a net positive," Stovall said. "The president wants to get some sort of deal signed so he can move on."
The Dow Jones Industrial Average fell 27.53 points, or 0.1 percent, to 26,384.77, the S&P 500 lost 1.83 points, or 0.06 percent, to 2,905.58 and the Nasdaq Composite dropped 8.15 points, or 0.1 percent, to 7,976.01.
