What happened

Shares of Verizon Communications (VZ -1.24%) slumped 10.2% in the first six months of the year, according to data from S&P Global Market Intelligence. The telecommunications stock lost ground amid the market's coronavirus-driven sell-offs and mixed earnings reports that highlighted the highly competitive state of the mobile wireless industry.

The coronavirus pandemic spurred closures for the majority of Verizon's stores, creating a more difficult environment for mobile hardware and service upgrades. The company's business held up relatively well, but coronavirus headwinds and the need to rely heavily on promotions to drive customer growth weighed on the company's valuation.
