Apple, Exxon, and Microsoft Atop the Largest US Companies List

With Exxon-Mobil (NYSE:XOM) reporting second quarter earnings that underwhelmed, Apple (NASDAQ:AAPL), which recently broke the bank in its best quarter ever, looks increasingly well-positioned to usurp the title of the world’s most valuable company. While Exxon-Mobil is constrained by the supply of oil and natural gas resources that it sells to generate revenue, Apple’s productive capacity is limited only by the ingenuity of the brightest minds the Cupertino, CA based business can put to use in crafting new products. Apple’s ability to produce revamped and renewed versions of its existing products gives it a major growth edge over energy companies. There will probably have been ten different versions of the iPad released five years from now, while crude oil supply is nearing peak production levels. It is for these reasons that a investor with a long-term outlook will likely come to the conclusion that Apple and other technology stalwarts such as Google (NASDAQ:GOOG) and Microsoft (NASDAQ:MSFT) have the potential to grow vastly. Financial writers have already begun to speculate that Apple (NASDAQ:AAPL) could be the first trillion dollar public company by 2020.
