Boeing had a great day on August 13, 2003. The company's stock rose more than 20%, to close at $2,015 per share. That was the highest closing price ever for Boeing shares.

The reason for the big jump was good news about the 787 Dreamliner program. Boeing announced that it had completed key design milestones and was making progress on building prototypes of the new airplane. Investors were bullish on Boeing's prospects, driving up the stock price accordingly.
