A company's value, as assessed by the market, declining is not always, or even often, bad. Healthy biology demands regular cellular death through apoptosis. The corporate landscape should not riddled with cancers of companies refusing to die when it's due.
With "share price over all" mentality, instead of clearing up funding toward declining companies like GameStop and AMC, you get a sudden resurgence of investment toward them via weird things like gaming passive index investing as scammers and hopeful suckers encourage and fall victim to the efforts of C-level grifters who have decided to spend their allegedly exceptionally valuable expertise perpetuating the scam instead of cutting it short.
They do this all while attacking the immune system (short sellers) that is trying to accelerate us toward being rid of their sludge. It's a meta-human autoimmune disease.
I realize I'm taking this to the extreme, but there are small steps that echo this tendency to live or grow at any cost. Forcing out annual products with exuberant marketing campaigns as a substitute for substance is an indicator of weakness or outright lack of understanding that sometimes to go forward you have to take some steps backward.
The stock market is a secondary market, there's no "pulling investments", it's just selling stock back on that secondary market. Unless an investor bailing on a stock is so large as to impact the share price or they have influence/seat on the board of directors companies don't tend to give a shit. Even if a big investor sells stocks that doesn't necessarily mean there will be meaningful impacts on share price, the market is irrational.
Predictable cash flows are good for more-or-less everyone. Luckily Apple has a massive cash reserve and can easily take the short term hit. I suppose you can take advantage of that knowledge and buy when the reactionary investors sell on, perhaps, lower revenues if and when the time comes.
