Fund Performance: Past performance and current investment strategies affect investor demand. Strong performance usually drives up the price.

Market Conditions: Broad economic trends and investor sentiment in the EU and globally influence the fund's value. Positive market sentiment will likely increase the price.

Underlying Assets: The performance of the assets (stocks, bonds, etc.) held by the fund directly affects its value. If the assets increase, the fund price will likely increase.

Expense Ratio: Higher expense ratios can reduce returns, making the fund less attractive and potentially impacting its price negatively.

Supply and Demand: If there are more buyers than sellers, the fund's price will rise. Conversely, more sellers than buyers will drive the price down.

Fund Size: Very large or very small funds can sometimes experience pricing inefficiencies. It might be harder to accurately reflect the value of the underlying assets.

Currency Fluctuations: Changes in currency exchange rates, especially between GBP (the fund's currency) and EUR (EU currency), can impact returns and influence the fund's price.

Interest Rates: Interest rate changes in Europe can affect the value of fixed-income investments held by the fund. A rise in interest rates may decrease the bond prices, potentially lowering fund price.
