Sector Wrap: Apple suppliers slump

NEW YORK (AP) -- Shares of companies that supply parts to Apple Inc. fell Wednesday after a company that makes chips used in the iPhone and iPad said revenue will slow down in the first quarter of 2013.

Cirrus Logic Inc. said sales of a particular chip have slowed down because a customer is moving to a newer component. Cirrus makes chips used in audio and energy products, and while it does not disclose customer names as a matter of policy, it's widely known that Apple is its biggest customer.

Shares of Apple slumped about 6 percent on the news and traded Wednesday at their lowest prices since December 2011.

Apple doesn't comment on announcements from its suppliers or disclose product plans. It is scheduled to report its first-quarter results Tuesday.

Cirrus shares lost $3.30, or 15.4 percent, to $18.11 in afternoon trading.
