I previously wrote about likely contributors to the success of Apple (AAPL) in the short term. For this year, the iPhone, which currently generates about two-thirds of overall revenue and the bulk of the profits, will be by far the most important part of the business and wield the most influence over the AAPL stock price.

However, since it is possible (likely?) that iPhone growth will slow going forward, what will drive things at the consumer tech giant over the long run, say the next five to ten years?

Apps

Although it’s still new (less than a decade old) and a relatively small chunk of the business at AAPL right now, apps will likely be a bigger piece of the puzzle going forward, especially if sales of devices slow.

Apps are categorized under the “Services” segment right now, which has been growing at a double-digit clip over the last several years. In a few years Apple will probably need to break it out as a separate line item, essentially admitting it’s a material contributor to the fluctuations of AAPL stock.

Apple gets a 30% slice of the proceeds from apps created for the mobile, Mac, and Apple TV lineups.  The App Annie site estimates that revenue Apple receives from its App Store is about double the value that rival Alphabet Inc (GOOG, GOOGL) derives from Google Play, in spite of half as many downloads.

The Apple Watch

The Apple Watch is new and so far AAPL has decided not to break out sales (it’s part of the “Other” segment right now). Shipment estimates to date range from just below 5 million to as high as 10 million. Assuming average selling prices of $500 to $600 that could mean $2.5 billion to $6 billion in “extra” annual revenue, and a few billion in profit, for Apple.

As new iterations are released, Watch 2.0 will probably be available in the fall of 2016, expect the revenue stream to increase and become a bigger catalyst for AAPL stock. Originally meant as a companion to the iPhone, future versions will likely be standalone mobile communication and computing platforms, ala Dick Tracy.

Apple TV

Reports that Apple would introduce a skinny TV bundle with 40-50 channels last fall never materialized. However, that doesn’t mean that AAPL won’t be successful in the space, either from a streaming service, an actual receiver unit, or in content. The new Apple TV that was released last year will be somewhat accretive to Apple’s bottom line, probably through a combination of apps and devices, similar to the mobile business.

The Apple Car

Rumors of an “Apple Car” abound. Tesla (TSLA) CEO Elon Musk calls it the biggest open secret in Silicon Valley and he derides the effort by claiming that engineers that can’t get a job working at his company go over to AAPL. I wouldn’t be so quick to think that Apple will put out an inferior product.

There are reports of development issues with “Project Titan,” as it is called, and since it probably won’t be on the streets for at least another five years, investors will have to wait until the next decade for the Apple electric vehicle to be added to the product mix. But, as they say, the possibilities are endless in this space.

Conclusion

The iPhone will dominate the headlines surrounding AAPL stock in 2016 but in the years that follow, apps, watches, TV products and services, and electric vehicles will likely steal at least some of the thunder in Cupertino. Investors with an eye out for the long term will surely benefit.
