Apple Inc. surpasses Exxon as most valuable company - momentarily
Apple Inc. is still number 2 in the US, but for a moment the company surpassed Exxon Mobile to become the most valuable company in America, Tuesday.
The two companies are so close that Apple is likely to gain, and keep, the top spot soon.
Apple shares gained 5.9 percent to $374.01 on Tuesday, bringing its market capitalization to about $347 billion.
Exxon Mobil's stock, meanwhile, closed up 2.1 percent at 71.64.
That gives the oil company a market cap of $348 billion as of the market's close. Its stock retreated earlier in the day, allowing Apple to take the lead.
