Underlying Index Performance: The price closely mirrors the performance of the underlying MSCI USA SRI index. Positive index movements typically drive the ETF price up, while negative movements cause it to fall.

Supply and Demand: High demand for IUS5.XETRA relative to supply pushes the price upwards, while increased supply compared to demand leads to price decreases.

Investor Sentiment: Overall market optimism or pessimism towards US equities and sustainable investing influences demand, impacting the ETF price accordingly.

Currency Fluctuations: As a EUR-denominated ETF investing in US equities, exchange rate changes between EUR and USD can affect the ETF's price when viewed in EUR.

Expense Ratio: While not a direct driver, the ETF's expense ratio slightly reduces returns, implicitly affecting its price over the long term compared to the underlying index's raw performance.

Trading Costs: Brokerage fees and bid-ask spreads encountered when buying or selling IUS5.XETRA effectively influence the total cost, impacting realized investment returns.
