An Infineon spokesman told Reuters that the company had 'not lost any contracts.'
At 1024 GMT, Infineon shares were 3.6 percent lower at 3.25 euros, rebounding from losses as sharp as 10 percent early on Tuesday morning.
Traders had earlier pointed to talk that Infineon had lost a key Apple contract.
'(I'm) hearing that they have lost a contract to supply chips for the iPhone. (There is) also talk that one of their main chips will be superseded by a competitor's next year,' said a trader.
A Frankfurt-based trader said at the heart of the speculation was a legal debate over 'pass through rights' which allow a handset maker to automatically acquire all intellectual property rights when they purchase chip technology.
Infineon has never officially said it has supplied Apple with the semiconductor chips used to make its best-selling iPhone, but several teardowns of the phone have claimed that Infineon makes at least two Apple branded parts in the phone.
