Apple’s stock hit $664.74 on Monday morning trading, taking the firm’s overall value to $619 billion, a touch higher than the $618.9 billion recorded by Microsoft in December 1999.
Claims of Apple now being the world's 'most valuable brand ever' can however be contested. After all, these figures do not account for inflation, for if they did they would place the Microsoft of 1999 as to be being worth just under $850 billion.
TechCrunch also reports that IBM would have been worth $1.3 trillion back in 1967, while others also point to the fact that Chinese oil company PetroChina was briefly valued at $1 trillion on the Shanghai stock exchange in 2007.
Apple surpassed Exxon Mobil as the most valuable brand in the world in January, but such has been its rise in recent months that today’s stock makes the iPad maker 53% more valuable than the oil giant ($405.6 billion), which sits in second place.
Shares at Apple have certainly had a helping hand in recent months on demand for Macs and iPads, as well as on the rumors that the firm plans to launch a smaller iPad and a flatscreen TV.
Things are not quite as rosy at Facebook and its social games subsidiary, Zynga. Facebook shares fell to $18.75 from $38 in May, while Zynga, creator of popular social game Draw Something, has seen its share value drop by 68% since going live on the stock exchange. There were also disappointing results for Groupon, the daily deals website.
