Nobody is worried about Apple&#x27;s survival. Barring doomsday scenarios, Apple looks set to be a very large, very profitable company for the foreseeable future. Just like Microsoft. They are worried about Apple&#x27;s growth prospects. Once the Chinese markets are saturated, where next? And if Apple does not innovate, they could end up losing market-share to competitors when they inevitably catch up. Once that point is reached, Apple&#x27;s only option is too undercut them on price (and with huge cash reserves and market clout, Apple is in a much better place to do this). But this means reduced margins, and  shrinking profits  (although they may stabilise to very respectable level). Apple has so far avoided this by staying ahead of the competition through innovation, entering new markets with sub-par competition like they did with the iPod, iPhone or creating entirely new ones like they did with iPad and iTunes. Before you say that Apple didn&#x27;t invent the tablet, the digital music marketplace, or the mobile software marketplace - None of that matters - in real money terms, Apple as good as did.<p>But what new markets are there for Apple to enter? People think the electric car market is a right fit for Apple. The article says that the global premium car market as a whole is currently only worth 220 billion dollars per annum ( don&#x27;t know whether this includes the premium compact market as well ) which is not much when considering the fact that  iPhone&#x27;s sale for previous 12 months was 100 billion. And the automobile market is highly competitive with plenty of incumbents with over 100 years of experience. Perhaps Apple could transform the business model of the market to make it much bigger, But like with the smartwatch, Apple is possibly late to the game, with Tesla, Google, Uber, all working frantically to do the same (each with their own vision and approach). In my personal opinion, Apple still has plenty of room to enter and exploit the market.<p>In conclusion, investors are worried whether Apple&#x27;s party of year-over-year growth in revenue and profits which it has sustained over the last decade is finally over.
