A 3% YoY growth in iPhone sales is a good accomplishment, but not all too impressive in my view given the current "booming" economic climate. For starters, the World population grows by 1% a year, and the number of people Worldwide who are advancing into a financial situation that could even consider buying an Apple product surely grew by more than 1% (emerging, advancing economies with growing middle classes). Secondly, this year was supposed to be an iPhone "super-cycle" and therefore the fact that there was a small 3% bump could be easily explained by "Pent-up demand" (people who waited out the 7) much more than by newly found enthusiasm for the iPhone in general. Lastly, we are in a massive Worldwide asset bubble right now, where low interest rates are still causing unjustified asset appreciation which in turn causes lots of "unorthodox" wealth to be produced. In times like this, one would EXPECT all those people making large windfalls to spend it on "status symbol" items like iPhones. So, given all those ideal and perfectly-bullish factors in 2018, the fact that iPhone sales only went up 3% is not that really impressive to me. What it tells me is that if/when any leg of that perfect economic stool is removed (or even weakened), YoY gains will not be possible any longer.
