Whoa! As of this writing (noon EST) Apple stock has reached a new high of US$493.85, which is a new a record. It also gives the company a market capitalization of $465 billion, which exceeds the combined totals of Google and Microsoft. Apple passed Microsoft in Market Cap back in May of 2010. At the current prices, Apple is comfortably ahead of Exxon Mobil, with has a market cap of about $400 million. Just yesterday we reported that Apple had gained $100 in share price since Steve Jobs died last October, but those numbers are already outdated.
