"Apple is no longer the world's most valuable company, with oil and gas company Exxon Mobil's market capitalization exceeding that of the iPhone maker's.
The former's shares further decreased by more than $11 to settle for a share price of $439.23, resulting in a market capitalization of $412.7 billion. With a 16-cent gain in Exxon Mobil's stock, the firm's market cap was propelled to $417.2 billion.
Apple had boasted a market value of approximately $623 billion back in the August of 2012, which is when pre-iPhone 5 launch hype was escalating; the firm's shares then exceeded $700."
