In the world of finance, and equities traded on the various stock exchanges, nothing is forever. However, this past week Microsoft saw its market capitalization surpass Exxon Mobil, a company that had long been the most valuable company until Apple surpassed it a couple years ago.

There was a temporary reversal between the two giants in their respective industries in the wake of Apple Maps mess. Cupertino recovered from that problem quickly though, and Apple has maintained a large overall value that even an energy conglomerate like Exxon Mobil is not likely to catch in the near future.

Microsoft’s fortunes have been taking a turn for the better lately, and that has reflected positively on the company’s stock, particularly over the past year, which has seen the stock increase over 40% since January.

All told, that gives Microsoft a market cap valuation of about $408 billion, which narrowly eclipses Exxon Mobil’s market cap of $402 billion. Both companies are having pretty good years though, so we expect these positions to switch a bit.

Of course, both Microsoft and Exxon Mobil are a distant second and third behind Apple’s $670 billion market cap, and that value is not likely to decrease any time soon, as the company is enjoying the brisk sales of its new iPhone 6 and iPhone 6 Plus smartphones.
