Boeing's stock price fell after the company reported for the 4th quarter of last year, which was better than expected, due to the deteriorating in forecasts. Thus, the net profit for the period totaled 1.03 billion dollars against 1.47 billion dollars in the same period last year. At the same time, the forecast of revenue in 2016 totaled 93-95 billion dollars against the previous estimate of 97 billion dollars. Despite the current decline, we expect the resumption of growth in the medium term due to the strong demand for passenger aircraft. The current decline may continue in the near future.
