As goes Apple, so goes Cirrus Logic (CRUS +7.1%). The audio codec chipmaker is taking off in sympathy with the customer than made up 85% of its March quarter revenue, one trading day after getting clocked due to downbeat remarks about FY14 sales. Likewise, iPhone/Galaxy S4 supplier Skyworks (SWKS +3.4%) is rallying following a post-earnings Friday decline caused by mixed guidance, and so is rival RF Micro (RFMD +3.2%). Broadcom (BRCM +2.5%), meanwhile, is adding to last week's strong post-earnings gains, fueled by a Q1 beat and solid guidance. The gains come even as another Apple supplier, Nam Tai, gets crushed due to weak guidance.
