Unless you are talking about a very specific period in the last ten years, Boeing's stock has not "shot up". It is barely up over the last decade in a period when the total US market has nearly tripled.
>Boeing stock is worth 4x what it was 15 years ago.
The S&P 500 is worth 5.4x over the same time period. There might have been some enthusiasm back in 2018, but in the past 5 years they've definitely underperformed.
It had gone up almost 10x from 2010 to 2020, then they got hammered by the obvious.
