Underlying Assets: EUNN.F tracks the performance of MSCI USA SRI index, so the price is heavily influenced by the prices of the underlying US stocks in that index.

Supply and Demand: Market forces of supply and demand for the ETF itself impact its price. Higher demand typically increases the price, while higher supply decreases it.

Expense Ratio: The ETF's expense ratio, while relatively small, can slightly affect the overall return and therefore the price compared to the underlying assets.

Currency Fluctuations: As EUNN.F is traded in EUR, currency fluctuations between EUR and USD can impact the price for EUR-based investors.

Market Sentiment: Overall investor sentiment towards the US stock market and socially responsible investing can affect the demand for EUNN.F.

Interest Rates: Changes in interest rates, particularly in the US, can influence the valuation of companies in the underlying index, thus impacting the ETF's price.

Economic Data: Macroeconomic data releases in the US, such as GDP growth, inflation, and employment figures, can affect the performance of US companies and the ETF's price.
