Apple has rattled investors with news that its sales have been slowing, blaming economic weakness in China.
In a surprise disclosure, the iPhone maker said it anticipated revenue of about $84 billion for the three months to December 29.
In November it forecast sales of at least $89 billion – a prediction that had already disappointed investors.
Apple’s share price sank more than 7 per cent in after hours trade, extending its more than 28 per cent slide since November.
The festive season is typically Apple’s strongest quarter.
