Skyworks (SWKS -13%) is tumbling thanks to the guidance accompanying its FQ1 beat. During its earnings call, Skyworks noted it's seeing emerging markets price pressure - Chinese 2G phones were cited as an example. The company also predicted international 4G adoption, which will require phones that support additional frequency bands (and thus contain more RF components) will provide a 2013 lift, as will Chinese smartphone wins. Samsung and Apple manufacturer Foxconn are 10%+ customers. TQNT -3.1%. RFMD -2.3%. AVGO -0.6%.
