Nuclear energy stocks have dropped significantly over the past year, with the Global X Uranium ETF (URA) down over 20%. Specific companies like NuScale Power (SMR), Oklo (OKLO), and Nano Nuclear (NNE) have seen steep declines, despite advancements in technology and partnerships. Investors are concerned about long timelines and lack of commercial revenues.
