Shares in Apple fell to the lowest level in more than a year after one of its suppliers slashed its profit guidance, prompting fears that sales of the computer and mobile phone giant's products had also slowed.
Its shares fell as low as $398.11 in Wednesday trading, before ending the day down 5.5% at $402.80, the BBC reports.
The fall came after one of its suppliers, Cirrus Logic, reported falling sales.
With Apple due to release its latest quarterly results next week, some investors fear that the numbers may be underwhelming.
