From the beginning of 2000 until its peak in 2012, Apple’s stock price rose from $27.97 to $702.10, an increase of 25 times. Yet Apple’s stock price decreased by 37% from its peak in September 2012 until the end of March 2013, from $702.10 to $442.66. What specific attributes of their operational performance do you think account for Apple’s stock performance before and after the peak?

Steve Jobs coming back, Innovations, and Tim Cook taking over as COO

Explanation:

The fluctuations in stock prices of a company are due to improved performance of the company in meeting it's objectives and perception that the business will do better in the future.

In the given scenario there was an initial increase in Apple’s stock price from $27.97 to $702.10, an increase of 25 times.

This can be attributed to the return of Steve Jobs as the CEO of Apple. There was a confidence boost by his coming back. Also there were various innovations like: iPhone, iMac, iPod, and iTunes. These improved the performance and by extension share price of Apple.

However when Tim Cook took over as COO he reduced production by half resulting in stock price decrease by 37% from its peak in September 2012 until the end of March 2013, from $702.10 to $442.66.
