Apple's shares closed at their highest ever on August 19 due to the hype surrounding next month's iPhone 6 launch, Digital Spy reported.

The tech giant's shares ended up at $100.53, an increase of 1.4% for the day and a new record for the firm when June's 7-for-1 stock split is taken into account.

The company's previous high came ahead of the iPhone 5's debut in September 2012, when shares reached $702.10, or $100.30 adjusted for the split.

Apple's stock also neared its all-time high in regular trading of $705.07, or $100.72 when adjusted for the split, which came on September 21 that year, the day the iPhone 5 went on sale.

Its shares peaked at $100.68 in midday trading on Tuesday, August 19.

Stock value has dipped since 2012 due to fears that current CEO Tim Cook would not prove as successful as his predecessor Steve Jobs, but the promise of the iPhone 6 and a possible debut for the iWatch have helped reverse the downturn.
