It is obvious that eventually the sales of any product, even the iPhone would eventually plateau. This means of course, the stock value would be no longer determined by some fancy dreams of growth but the actual financials of the company. With the share price going down, the resulting hit might have already happened. But this still would mean that the most profitable company plateaus, not a bad place to be. Also the outlook isn't so bad either. The iPhone 6 sold much better than all analysts predicted and I wouldn't be surprised if the 6s might not even beat it - a lot of the iPhone users who did not have a 6 were upgrading this year (including myself). And with the 7 we might get the 6 owners renew after 2 years. The iPad sales have been slow - I myself haven't upgraded my iPad 3 yet - but if the Pencil technology comes to the full line up, it could drive a lot of interest into renewing. And while the Apple Watch might not large by business volume yet, it owns the large part of the smartwatch market. There will be huge improvements with the next generations, so a lot of growth there. Also you cannot use the Apple Watch without a modern iPhone, so with the iPhone renewals there are more potential customers.
