Apple Was Most Valuable U.S. Company

Stocks are going haywire in the current erratic market, so much so that Apple had a brief moment in the spotlight as the most valuable company in the U.S. For part of Tuesday, Apple's market value climbed to $341.5 billion, inching past ExxonMobil’s $341.4 billion. But the oil giant makes more than four times Apple’s annual revenue, the technology company’s claim to fame as the largest company in the U.S. was fleeting. Apple closed at $374.01 today, up 5.9 percent, giving it a market value of $346.7 billion. Shares of Exxon rose 2.1 percent to $71.64, valuing the company at $348.3 billion.
