Shares of Apple’s stock hit the $600-mark on Tuesday for the first time since April 27th. The company’s stock price sky-rocketed earlier this year after Apple reported the most profitable quarter in history among technology companies, and the second-most profitable quarter ever among all U.S. companies. AAPL hit $500 in February, and it first climbed above $600 this past March as investors anxiously awaited the launch of the company’s latest iPad tablet. Since touching $600 shortly after 11:00 a.m. Eastern on Tuesday, Apple’s stock has dipped slightly and was hovering around $599.50 at the time of this writing. Renewed chatter surrounding the upcoming launch of Apple’s rumored iPad mini is credited in part for today’s jump to $600, as is the dismissal of chatter that Wintek’s disappointing June might point to a slow month for sales of Apple’s mobile devices.
