(USA TODAY) -- Amazon and Facebook continued to rise up the world's most valuable companies list on Friday, passing Exxon Mobil in market cap in morning trading.
At the beginning of trading the retail giant and social networking behemoth quickly jumped ahead of Exxon, which was down following disappointing second quarter earnings. Exxon, like rival gas producer Chevron, has struggled as oil prices in the U.S. continue to remain low.
Exxon's stock opened down around 4%, though it has since picked up slightly and as of 10:50 a.m. ET is down around 2.5% to $87.94. Its market cap currently sits at $360.84 billion, according to Google Finance.
Facebook's surge only adds to an already impressive week. On Wednesday the company announced it had 1.71 billion monthly active users producing $6.44 billion in revenues for the quarter. Mobile, once a challenge for Facebook, represented 84% of $6.24 billion in advertising revenue.
As a result the company's stock is now trading at an all-time high, up slightly to $125.61. Its market cap currently sits at $364.26 billion.
Facebook's passing of Exxon marks a fluid list of the world most valuable companies. Apple ($567.75 billion), Google ($546.49 billion) and Microsoft ($445.14 billion) remain the three largest, but those below it have seen a shuffling. Berkshire Hathaway has fallen to $355.63 billion, being passed by Facebook as well as Amazon who saw its own jump following strong earnings Thursday.
At around $366.95 billion Amazon has passed Berkshire Hathaway, Exxon and Facebook to jump to fourth on the list. The stock continues to rise on Friday morning, currently up 1.3% to $762.74.
