CEVA (CEVA -12.8%) is ending the day with huge losses after Broadcom, which uses CEVA's DSP cores in its baseband chips, missed Q2 estimates and issued light Q3 guidance, while blaming the shortfall in large part on light baseband sales. Chip stocks on the whole have had a bad day (SOXX -1.8%), as Broadcom's numbers and a ho-hum report from ARM overshadow Apple's FQ3 beat. SIMG -3.8%. OVTI -2.8%. MU -3.9%. SNDK -2.4%. IMOS -4.5%. Broadcom set-top chip rival STMicroelectronics (STM -2.7%) has fallen for the second day in a row following its Q2 report and soft Q3 guidance, aided by a downgrade to Underperform from BofA.
