Apple re-overtakes Exxon Mobil

The computer maker is once again the world's most valuable company

As the Dow Jones industrial average plunged another 500-plus points Wednesday, Exxon Mobil (xom) plunged more than Apple (aapl) and once again gave up its long-held spot as the No. 1 public company in the world in terms of market capitalization.

When the closing bell rang, Apple closed on top for the first time. The tale of the tape looked like this:

Co. Price Change % Market cap
Apple $363.39 -10.32 -2.76% $337.17 B
Exxon $68.03 -3.14 -4.41% $330.77 B

On Tuesday, Apple's market cap (share price times number of shares outstanding) briefly overtook Exxon's, although Exxon ended the day ahead. See here.

One day later, Apple became the world's most-valued company by a cool $6.4 billion.
