SAN FRANCISCO – Shares of Cirrus Logic were down more than 8% on Wednesday. Pacific Crest Securities analyst John Vinh reiterated an underperform rating on the stock, arguing that "fundamental demand trends will get worse before they get better." Cirrus Logic is known to be an Apple Inc. chip supplier. "We anticipate the deceleration in Apple iPhone demand is still likely to put forward estimates at further risk," Vinh told clients in a note.
