1. KGI is now forecasting ZERO or negative growth of iPhone sales in Q4 2015. Basically saying that the upcoming iPhone 6s wont be good enough to grow apple phone business.
2. China weak economy will have a negative impact on sales of the iPhone.
KGI expect AAPL to sell 'only' 65 to 75 million phone in the last quarter of the 2015 ( compared to 75 million iphone sold in Q4 2014).
I will continue to hold AAPL in my portfolio, it's a great stock with very nice dividend yield. But if you must sell , sell it at the end of the month if the stock trade below $111.17.
