(San Francisco)

The market fell in a big way yesterday. The root cause? Apple. Apple has cut its iPhone sales guidance, and it now seems a recession is coming to the whole Apple universe. The numerous companies that make their living supplying Apple seem set for a severe correction and are paring their estimates back sharply. Investors didn’t seem ready for this slowdown in the iPhone, perhaps misguided by the hype that has recently surrounded new models. The fact is that the iPhone is now a mature product, and maintaining the kind of growth it once had is likely untenable, a fact that even Wall Street analysts are starting to admit.

FINSUM: Apple’s business is changing and it seems to be doing a good job managing that transition, though everyone hopes it will have a new dynamite product. That said, a general recession surrounding the iPhone universe seems likely.
