12:28 PM Up initially following its Q1 beat, Texas Instruments (TXN -1.3%) has reversed course, possibly due to worries about a massive drop in wireless chip sales. During its earnings call, TI noted sales of "connectivity" products such as Wi-Fi chips were soft, to go with an expected plunge in baseband chip sales (a business TI is exiting). Is that a sign TI is losing share to Wi-Fi chip leader Broadcom (BRCM -1%), or (along with ARM's shipment data) one of soft industry sales?
