Is Qualcomm Stock a Buy?

It's been a tumultuous few years for Qualcomm (NASDAQ: QCOM). Its bid to take over peer NXP Semiconductors was blocked by China; there have been patent and licensing disputes with Apple (NASDAQ: AAPL) (which it resolved in 2019) and with Chinese tech titan Huawei (a new long-term agreement is still pending); and the trade war between the U.S. and China has been the source of frequent worry. Tech researcher IDC thinks global smartphone sales could drop 12% in 2020 as a result of the pandemic.
