Growth catalysts for Apple “already occurred”

Apple Inc. (NASDAQ:AAPL) announced a higher capital program of $100 billion under which it will increase its dividend by 15% along with increasing the share repurchase authorization to $60 billion. In its June quarter, the company utilized $16 billion on share repurchase activity, setting an aggressive repurchase pace.

Apple Inc. (NASDAQ:AAPL)’s new iOS7 was launched in a developer’s conference in June. The Cupertino-based company also launched new lines of iPhones, iPads and Macintosh computers in September and October. Also, Apple achieved $9 million in sales of its new iPhone just three days after the launch, which fueled the total revenue and gross margin for the September quarter to the near high end of its previously provided guidance. With such impressive sales numbers, analysts believe that the iPhone maker has entered into its historically strong holiday quarter.

Apple Inc. (NASDAQ:AAPL) announced in an event that it sold its 170 millionth iPad earlier this year. However, it indicated that sales in the September quarter will be less than 15 million units.

Potential catalysts remaining
