With a market cap of over $765 billion, Apple is now worth at least double any other publicly traded U.S. company, including the no. 2 ranking Exxon Mobil, whose current market cap is $374 billion. S&P Dow Jones Indices’ Howard Silverblatt points out that on a year-end basis, the last time the biggest company by market value was worth at least double the second-largest was 30 years ago (via The Wall Street Journal).
At the conclusion of 1983, 1984 and 1985, International Business Machines Corp.’s market cap was more than twice Exxon, which ended each of those years in second place. At its widest year-end point back then, IBM was worth 140% more than Exxon.
Three decades hence, the most-valuable company is worth more than 10 times that and is a 30% stock jump from becoming the first trillion-dollar company.
Back in 2008, Exxon was nearly double the market cap of the then no. 2 ranking companies, which alternated between Microsoft and Wal-Mart. However, since Apple first got past Exxon in 2011, the company has largely held the top spot uninterrupted.
The gap between Apple and Exxon has grown significantly in 2015 with Apple up 19% and Exxon falling 3.7%.
