Though things could change again tomorrow, Apple on Thursday once again became the world's most valuable publicly-traded company by market cap, rising $4.15 (nearly a percentage point) to close at $456.68 per share (and still rising in after-hours trading, currently at $457.65). With a value approaching $415 billion, the company re-took the crown from Exxon Mobil, which fell by a dollar after a bad earnings report and lowered its overall market cap to $412 billion. AAPL has risen almost $50 over the past month, but is still off its 2013 high of $549.03 per share.
