Underlying Asset Performance: The IEU.AU ETF mirrors the performance of European equities. Positive or negative movements in European stock markets directly impact its price.

Currency Fluctuations: As the ETF invests in European assets, changes in the AUD/EUR exchange rate influence its value. A stronger AUD reduces the AUD value of EUR-denominated holdings.

Supply and Demand: Market demand for IEU.AU relative to its available supply affects its price. Higher demand generally leads to a price increase.

Interest Rates: Changes in interest rates, particularly in Europe and Australia, can influence investor sentiment and the attractiveness of the ETF.

Economic News: Major economic announcements from Europe, such as GDP figures, inflation data, and unemployment rates, impact investor confidence and the ETF's price.

Geopolitical Events: Global events, political instability, or regulatory changes in Europe can affect investor risk appetite and the ETF's value.

Dividend Payments: While primarily focused on capital appreciation, dividends paid by underlying European companies can contribute to the ETF's overall return and indirectly influence its price.
