Apple now most valuable firm

Apple became the most valuable public company of all time yesterday, breaking a 13-year record as speculation mounted about new versions of its iPhone and iPad as well as a set-top box to deliver live TV.

The Californian firm reached a market capitalisation of $623.5bn in trading yesterday, overtaking the $618bn Microsoft hit in 1999. Apple’s share price has risen steadily since it became the world’s most valuable company last year.
