Apple has been losing market share. While the larger screens on the 6 and 6+ may help them retain market share, their margins have been shrinking bit by bit.

They have 5% of the PC market but manage to make 50% of the profits made in the PC industry. This represents huge gross margins, and unsustainable gross margins.

Apple has also abandoned their customers that loved the small size of their phones. I'm not saying this is a huge factor, but it is going to make some of their loyal customers look at other phones.

With the iPad their best selling model is the mini which has the lowest margins.

Apple TV is a decent product, but not an overwhelming success. I don't see a lot of demand for an Apple TV.

Apple is a solid, profitable company, but I don't see the opportunity for growth that would double the stock price.
