Apple m-cap at $500 b

Apple’s market capitalisation has topped $500 billion.

Apple was already the world’s most valuable company.  The company’s market capitalisation climbed near $508 billion as shares rose $8.76, or 1.6 per cent, to $544.17.

Apple is a rare company and is the sixth US corporation to reach the $500 billion milestone. Exxon, now worth $411 billion, was worth just over $500 billion for two short stretches at the end of 2007.
