Underlying Asset Performance: The primary driver is the performance of the stocks comprising the FTSE Developed Core Infrastructure Index. A rise in these stocks will lift the ETF's price; a fall will depress it. Interest Rate Changes: Infrastructure companies are often sensitive to interest rates. Higher rates can increase borrowing costs, potentially reducing profitability and thus the ETF's appeal. Inflation: Inflation impacts infrastructure companies' costs and revenues. How successfully they can pass rising costs onto customers affects their stock values and, therefore, the ETF's price. Economic Growth: Stronger economic growth usually increases demand for infrastructure services, positively influencing infrastructure company performance and ETF price. Slower growth has the opposite effect. Geopolitical Events: Major global events can create uncertainty, affecting investor sentiment and potentially impacting the ETF's price. This is particularly relevant given the global nature of infrastructure assets. Currency Fluctuations: As RIZF.DU likely holds international assets, currency movements between the Euro (its trading currency) and the currencies of the underlying infrastructure companies impact its value. Supply and Demand: Basic market forces of supply and demand also play a role. Higher demand for the ETF relative to its supply will drive up the price, and vice versa. Fund Management Fees: The ETF's expense ratio can indirectly affect its price by lowering overall returns. A higher expense ratio means less net return for investors.
