• Boeing (BA) shares rose on word that the US and China are in the final stages of negotiations for a “huge” Boeing Co. aircraft order, US Ambassador to China David Perdue said, as the two nations look to thaw frosty ties and work toward a trade deal. While Perdue didn’t offer details on the size of the potential order, his comments at a briefing in Beijing alongside a visiting delegation of US lawmakers indicated that the deal will be locked in swiftly. “This is a huge order, and it’s very important to the president. Very important for Boeing. I think it’s very important to China,” he said Tuesday. “I think that we’re in the last days of that, weeks of that negotiation, and we’re hopeful that that will turn out to be the case.”

The night before President Donald Trump had launched into a tirade about the medication long recommended during pregnancy to treat fevers and aches and pains.
