Apple has reclaimed its title as the world's most valuable company this week, after a strong month that helped push Exxon Mobil out of the top spot.

On Thursday, Apple's market capitalisation was around $414 billion with stock creeping as high as $456.80. Exxon Mobile, on the other hand, saw its shares drop by more than two per cent after its earnings report disappointed investors. This left its market cap at around $408 billion yesterday, as highlighted by Apple Insider.

At time of writing, Exxon's market cap has risen to $412.31 billion, but Apple continues to maintain its $414.86 billion market cap, holding on to the title of the world's most valuable company for now. Apple held on to the top spot throughout 2012, but was overtaken by Exxon earlier this year when Apple's stock plummeted.

The rise in Apple share price comes as speculation about upcoming products hots up. Investors are hoping that Apple's rumoured iPhone 5S, iPad 5, iPad mini 2 and low-cost iPhone could help bolster the company's sales.

Looking further ahead, Apple is also rumoured to be working on an iWatch device, and also a venture into the television market, possibly through the launch of an advanced set-top box or an Apple-branded TV set.

Plus, the new Mac Pro, which has already been previewed by Apple, is expected to hit the shelves later this year too.
