Wall Street was mixed in light trading early Tuesday as anxiety dissipated somewhat after President Donald Trump agreed to a 30-day pause on his tariff threats against Mexico and Canada. Trump's imposed tariffs on China remained in place.

China, which Trump announced will get hit with a 10 percent tariff starting Tuesday, will reportedly have a call with the White House soon. Early Tuesday, Beijing announced a 15 percent levy on certain types of coal and natural gas, and a 10 percent tariff on various vehicle parts, machinery, and crude oil.

Stock market returns under presidential administrations are more correlation than causation, regardless of what political pundits say.
