Barely a year after supplanting Exxon Mobil as the largest stock in the current marketplace, Apple entered the record books Monday, becoming the most valuable stock to have ever traded.
Apple closed Monday at another historic high of $665.15, ending the day with a record market cap of $623.5 billion.
With Monday’s gain, Apple eclipsed Microsoft’s peak market cap of $618.9 billion, a level that Microsoft hit over 12 1/2 years ago, on Dec. 30, 1999. That happened at the height of the dot-com boom and just three months before the Nasdaq Composite peaked at its all-time high of 5,132.52.
