Boeing Co shares ended up 0.5 percent at $377.14, recovering from a more than 3 percent fall in the afternoon, when the United States announced it was grounding Boeing's 737 MAX jets following Sunday's fatal crash in Ethiopia. The U.S. Federal Aviation Administration cited new satellite data and evidence from the scene of Sunday's crash, the second disaster involving the 737 MAX in less than five months. Boeing shares are still down about 11 percent since Friday's close.
Tim Ghriskey, chief investment strategist at Inverness Counsel in New York, said the grounding gives Boeing time to address any problems and not face another potential disaster. "It seems like the worst is over for Boeing," he said. "The fact that (the stock) appears to be stabilizing means the market appreciates that."
