Why Vivint Solar Inc.'s Shares Plunged 28% in September

Shares of Vivint Solar Inc. (NYSE: VSLR) plunged 28.4% in September, according to data provided by S&P Global Market Intelligence, as it became clear that tariffs on solar panels may be on the horizon.

As part of a trade case involving Suniva and SolarWorld, the International Trade Commission has said that the domestic manufacturing industry has been harmed by imports. That means the commission will recommend some sort of remedy, potentially including very punitive tariffs on solar imports that would dramatically raise costs for Vivint Solar and its competitors.
