This exchange-traded fund (ETF) commits a substantial portion—at least 80% of its total assets, potentially supplemented by borrowed capital—to investments aligned with its benchmark index. Such investments include direct holdings in the index's underlying securities, along with American and Global Depositary Receipts (ADRs and GDRs) linked to those same companies. The benchmark index itself is specifically designed to provide investors with exposure to businesses that stand to profit from ongoing advancements in solar energy technology.
