Check out the companies making headlines midday Tuesday:

Micron, Qualcomm, Broadcom – Chip stocks staged a comeback after the U.S. granted a 90-day license for mobile phone companies and internet providers to work with Huawei. The temporary relief prompted Google to reverse its decision to cut ties with the Chinese telecom giant. The semiconductor sector took a hit Monday on fears chipmakers would lose a big customer as Huawei purchases about $20 billion U.S. chips a year. Micron rose more than 2% Tuesday while Qualcomm and Broadcom closed 1.5% and 1% higher, respectively.
