Bruh, not advice and I am not a whatever, but take the L and cash out while you can. Stay well away from anything that has to do with American "industry" because that's going nowhere but down.
Just buy S&P and sit back while the US government inflates the bubble. Stonks only go up.
The US switched from the classic and the best form of capitalism - industrial capitalism (actually producing tangible things like China is doing for example) to financial capitalism, in general in the last few decades, so of course companies still have to do anything with physical manufacturing like Boeing will have worse and worse conditions to operate in as the time goes by. In the industrial capitalist model, companies invest in factories, materials, and workers to produce goods. So, all of this is lacking now inside of the US on a national level.
Financial capitalism is about playing with money to make more money. Instead of factories and products, the focus here is on financial markets, like stocks and bonds. It involves stuff like investment, trading, and managing financial assets and similar zero-productivity stuff. Here, the value is in the money itself and how it can grow through various financial machinations. It's less about making real tangible things and more about passively managing and multiplying money with financial engineering for the wealthy class.
But another factor is that the US also switched from "productive capitalism" to "rent-seeking" capitalism in general too. And this is how Boeing generates most of its new revenue nowadays. "Rent-seeking capitalism" is basically when companies or oligarchs find ways to make more money without really adding anything valuable to the economy/society but by stealing from it as much as possible.
This includes stuff like controlling the government more and more through political lobbying, creating monopolies, influencing government policies in their favor, controlling regulatory bodies, buying patents just to sue others, or even outright bribery. Taking value instead of making value and this is probably everything that Boeing is doing as well. They are also doing more and more "virtual" share buybacks, and dividend payments, instead of actual real R&D. In my opinion, it's only a matter of time before the US loses even these last few manufacturing industries.
