Boeing forecasts 2016 earnings below estimates; shares tumble

Boeing Co forecast 2016 core earnings below estimates on Wednesday, and said it expected to deliver fewer commercial planes this year, sending its shares down 6.5 percent. Boeing also reported weaker fourth-quarter profit. The company attributed the decline to a slowdown in the 737 line as Boeing shifts production to a new version of the plane, the 737 MAX, and to a slight reduction in output of 747-8s as it slows production of the jumbo jet late next year in response to weak demand.
