Solar stocks shine after Trump extends China tariffs to polysilicon products

U.S. solar shares surged in early trading following President Donald Trump's announcement of new tariffs on China-made polysilicon products, used in solar panel manufacturing. The 15% duty on these products, along with minimum price requirements for related imports, was aimed at safeguarding domestic solar supply chains from Chinese competition.

Stocks like First Solar and SolarEdge Technologies saw significant gains, with First Solar up more than 7% and SolarEdge Technologies rising 1%. The Invesco Solar exchange-traded fund also experienced a 4% increase. The tariffs were imposed under Section 232 of the U.S. Trade Expansion Act of 1962, following advice from Commerce Secretary Howard Lutnick.

The move is part of the U.S.'s strategy to bolster its domestic chip and solar supply chains, and to compete with China in the artificial intelligence and energy sectors. Trump stated that for decades, foreign countries had weakened U.S. polysilicon producers, undermining economic and national security, and vowed to take action to revitalize the U.S. polysilicon sector.
