The worlds largest company by market capitalization, Apple is known for its perfectionism, attention to detail and secrecy. For investors the kicker is that the iPhone is remarkably cheap to manufacture: Gross profit margins are typically estimated to be about 65 percent. Among consumers the iPhones success can be attributed to its sleek design and groundbreaking technology, which have helped foster an almost cultlike following. From May 2007 through May 2015, Apple rose from $17 to more than $130 a share (adjusted for a 7-for-1 stock split in 2014). The performance of Apple stock has almost directly tracked that of its smartphone. Since the introduction of the iPhone in June 2007, Apple has sold more than 1 billion units around the globe. The iPhone is the most successful product in Apples history, making it arguably the single most successful product in the history of the world. Cook captioned his tweet: Taxi!
