Underlying Index Performance: The primary driver is the Solactive Sustainable Global Developed Markets Momentum Select Net TR Index's performance. This index tracks the momentum of sustainable developed market stocks.

Supply and Demand: Like any ETF, market supply and demand influences its price. High demand can push the ETF's price above its net asset value (NAV), while high selling pressure can cause it to trade below NAV.

Currency Fluctuations: Since the ETF invests in global markets, currency exchange rates between the Euro and the currencies of the underlying assets can impact returns when translated back into Euro.

Expense Ratio and Trading Costs: The ETF's expense ratio (ongoing costs) and any trading costs incurred by the fund manager can slightly affect returns and, indirectly, its price relative to its underlying index.

Changes in Momentum Factors: Alterations in the market's definition of "momentum" or changes in the performance of high-momentum stocks can affect the index and, consequently, the ETF's price.

Sustainability Criteria: Changes in sustainability standards or investor sentiment towards sustainable investments can impact demand for the underlying assets and therefore the ETF price.
