Boeing revenues declined YOY by 24.5% so that is how I know the 24% stock price increase was stock buy back
he first quarter sales were significantly down, primarily due the Dreamliner crisis. Sales dropped almost 15.3% on a QoQ basis, and fell by approximately 2.5% on a YoY basis. The Commercial Airplanes segment, within which the 787 is reported, faced a decline in revenues of around 2.3% on a YoY basis, and a staggering 24.5% on a QoQ basis. As per my estimates, the effect of the 787 battery crisis on the Commercial Airplanes segment's revenues was from $3 to $4 billion.
