InterDigital (IDCC) caught the attention of George Tsilis on today's Overlooked Stocks segment. He walks through the company's unique cross-section exposure to global OEMs like Alphabet (GOOGL) and Lenovo. George says IDCC competes with Rambus (RMBS), Nokia (NOK), Ericsson (ERIC) and Qualcomm (QCOM). He dives into the stock's wireless, ioT and automotive sector presence, and points to the company's expansion in net income margin as a key growth metric to monitor.
