During trading on NASDAQ today, Apple Corp (AAPL) reached a closing price of $US665.15 (up 2.63% on the day) and at the time of writing was a little higher in after-market trading at $US665.39.
This has finally beaten Microsoft's 1999 intra-day valuation record of $US620.58B set on December 30th.
Of course this does not take account of inflation – Microsoft's 1999 peak valuation would represent a market capitalisation of $US850B in current dollars.
Currently, Apple is riding the wave of support for the upcoming iPhone 5 (or whatever it is to be called) and amongst many other outlets, iTWire has written extensively about this upcoming release.
This is of course is a far cry from the fortunes currently experienced by a certain social media darling organisation who's share price seems to be on a rather terminal decline. A share price of $38 on opening just a couple of months ago and less than $20 now is hardly a vote of confidence.
