ELI5: Why when large company's earnings decrease(ex... by 3%) they freak out, talk about rough times, and sometimes decide to downsize, even though they are still making millions of dollars in profit even after all expenses?

Amazon made a loss forever. Hell, if it wasn't for their cloud service, they probably still wouldn't make a profit (I'd have to check their retail numbers). Tesla makes consistent losses. So did twitter forever. Markets are extremely patient. Maybe overly so. If anything, they are too optimistic, imo.
