Unless you think any new iteration of the iphone bears a letter S at the end.
Then the show will continue and fanbois ripped for all they are worth.
The price of Apple's stock has hit the highest point since January following the release of new ranges of iPads and Macbook Pros. Cupertino's shares closed yesterday at $533.40, a rise of two per cent. This is the highest level since January, when Apple's stock was midway through its slump from a 2012 peak of around $700. …
Pretty sure Apple have almost 1/4 to 1/3 of their market cap in CASH (or equivalent) - their problem is a lot of it is abroad. Take what that cash is work off their market and see what sort of ratio they are trading at then compare to other similar companies. Apple are making real profits yet trading at a very low ratio which could indicate either that the shares are undervalued compared to their peers or people are overly negative about their future.
From the share price it would seem that investors are coming back in droves.
The price isn't even unusual for a company of its size. The financial number to look at is something called PE ratio, the ratio of share price to earnings per share. Historical PE ratios have averaged around 10-20 for stock market listed companies. Above 20 is regarded as overpriced, below is underpriced. Apple are currently at about 13.
With any market there is a well known pattern of sales for a new product. You can see the effect for iPods quite nicely. First it is new technology and expensive, then the average price falls and volume increases as the market matures, and finally the market shrinks as it is replaced by something new. Given that the market (and Apple's sales) are still increasing then we still haven't hit maturity for both smartphones and tablets, and it will be some time past that point until Apple have a problem, ASSUMING they never invent a single other new product.
