Microsoft revenue increased a lot when Steve Ballmer was in charge. I don't think anyone would claim MS was a great organisation during that period though, given how many major industry trends they just totally missed. Ballmer didn't trash the business but the action moved elsewhere.
As for Apple, putting the questionable meaning of the stock market to one side for a moment, when was the last time they did anything truly exciting, that cut their competitors legs out from under them? The M1 chip? That's the only thing I can think of for a long time, and it's a bit unclear how much consumers will care vs geeks.
