Away from the banks, Delta Air Lines Inc. DAL, +0.42%  shares jumped more than 5% in premarket action after topping profit and revenue expectations.

Analysts said the start of earnings season could take the spotlight away from U.S.-China trade issues ahead of the expected Wednesday signing of a so-called phase-one agreement. The U.S. Treasury late Monday lifted its designation of China as a currency manipulator. News reports that such a move was imminent helped buoy stocks during the session.

“Markets will be hunting for signs of apprehension over this reporting season with outlooks and sentiment more pressing given where we are valuations-wise,” said Bethel Loh, macro strategist at ThinkMarkets, in a note. “Even if we do catch some subpar results, simply issuing a positive outlook on forward guidance is all of the sugar hit markets need to be swayed to stay long.”

China’s yuan has strengthened since late last year, taking back much of the ground lost in a late summer swoon, aided by increased optimism over trade policy as well as early signs the Chinese economy is stabilizing, economists said.
