Cost Apple exceeded 500 billion dollars

Apple's market capitalization which earlier this week for the first time in the history of the company exceeded 500 billion dollars reserves the title of the most expensive companies of the world. In mid-February, Apple shares broke through for the first time in 500 dollars, and at the close of trading on the NASDAQ on Friday their value stood at 545.18 per security-one third higher than at the beginning of the year 2012.
