Underlying Assets' Performance: The IE00BDFB5F89.EUFUND fund's price is primarily driven by the performance of the assets it holds. These assets, typically stocks or bonds, directly influence the fund's net asset value (NAV).

Market Sentiment: Overall investor confidence and market trends significantly impact the demand for the fund. Positive sentiment can lead to increased investment and higher prices, while negative sentiment can cause redemptions and lower prices.

Interest Rate Changes: Fluctuations in interest rates, especially if the fund holds bonds, affect the fund's value. Rising interest rates generally decrease bond values, while falling rates can increase them.

Currency Exchange Rates: If the fund invests in assets denominated in currencies other than the base currency, exchange rate fluctuations can impact the fund's value when translated back to the base currency.

Expense Ratio: The fund's expense ratio, which covers management fees and operational costs, directly reduces the fund's returns. A higher expense ratio can lead to lower overall returns and thus affect the fund's price.

Fund Flows: Significant inflows or outflows of capital into or out of the fund can temporarily affect its price. Large inflows may lead to buying pressure, increasing prices, while large outflows may trigger selling pressure, decreasing prices.

Economic Conditions: Macroeconomic factors such as GDP growth, inflation, and unemployment rates influence the performance of the underlying assets and, consequently, the fund's price.
