VanEck Low Carbon Energy ETF (SMOG) seeks to replicate as closely as possible, before fees and expenses, the price and yield performance of the MVIS Global Low Carbon Energy Index. The index tracks the performance of renewable energy companies, which may include those involved in wind, solar, hydro, hydrogen, bio-fuel or geothermal technology, lithium-ion batteries, electric vehicles, and smart grid technologies. The fund normally invests at least 80% of its total assets in stocks of low carbon energy companies.
