In downgrading Broadcom (BRCM -1.4%) to Hold, analyst Chris Caso expressed concerns soft carrier capex will take a toll. Though chip sales for hardware used by carriers make up less than 10% of Broadcom's revenue, Caso points out they carry "the highest margins in BRCM's portfolio." He's worried China Mobile's (CHL +1.2%) giant 4G rollout could be delayed, given orders haven't yet been placed, CHL's 3G rollout was "beset by many delays," and Analog Devices (NASDAQ:ADI) talked of delays during last week's earnings call.
