Apple AAPL got clobbered Thursday, losing $10.32 (2.5%) to close at $401.82. But it got clobbered less than the rest of the market. Exxon Mobil XOM , in particular, fell 3.79%.

Bottom line: Apple, whose market capitalization trailed Exxon’s by $50 billion three months ago, and which first overtook Exxon six weeks later, is now the world’s most valuable public company by $35.87 billion.
