President Trump's attempts to reverse eco-friendly policies set by the Biden administration have had a positive impact on South Korea's solar industry. Solar companies like Hanwha Solution are experiencing growth, with the expectation that Trump's tariffs on Chinese solar products will be beneficial. Additionally, nuclear power stocks, including those of new SMR power plants, and utility stocks like LS Electric are on the rise. The solar, nuclear, and utility industries are benefiting from the strong performance of renewable energy-themed ETFs, which invest in various sectors including solar, nuclear, and hydrogen. The expansion of the AI industry is contributing to the growth of utility stocks, with companies like Doosan Energy and LS Electric seeing significant increases. Hydrogen-related ETFs, such as 'RISE Hydrogen Economy Theme,' have surged in value, with firms like Hanwha Aerospace and POSCO Holdings driving the rise. Hanwha Aerospace's focus on hydrogen fuel cells and POSCO Holdings' development of hydrogen-reduced steel technology are contributing to the positive sentiment surrounding the hydrogen industry.
