Investors panicked, and the stock sunk by nearly 30% from its 2012 peak.
IPhone 5 and iPad sales were marred by supply shortages. After months of long delays, Apple is now finally able to satisfy customers' demand for its gadgets, though the wait for an iPad mini remains one week on Apple's online store.

The stock has ended its free-fall, but Apple exits the year with some serious questions about its ability to innovate in a post-Steve Jobs world.
