Tim Cook

If you bought stock in Apple when Tim Cook became CEO in August 2011, you have had a solid return on your investment since that time. The company's market capitalization reached a new high of $700 billion on Monday before finally pulling back a bit in final trading. That means Apple's market capitalization has doubled since Cook began running the company.

While some financial analysts may have had doubts about Apple's future when its co-founder Steve Jobs passed away in October 2011, that's certainly not the case anymore. Apple's highly successful launch of the iPhone 6 and iPhone 6 Plus earlier this year has corresponded to a 24% percent increase in Apple's stock price since their release. There's nothing to suggest that Apple's success story will hit any bumps anytime soon.
