Underlying Assets: The performance of the assets held within the IE00B3NFBQ59.EUFUND significantly impacts its price. A rise in the value of its holdings typically leads to a price increase, and vice-versa.

Market Sentiment: Overall investor optimism or pessimism towards the specific market or sector the fund invests in influences demand and, consequently, its price. Positive sentiment can drive prices up, while negative sentiment pushes them down.

Supply and Demand: Like any asset, the balance between the number of investors wanting to buy (demand) and those wanting to sell (supply) shares of the fund directly affects its price. Higher demand usually results in a price increase.

Expense Ratio: The fund's operating expenses, reflected in its expense ratio, indirectly influence price by affecting the fund's net asset value (NAV). Higher expenses can slightly reduce the fund's returns and, therefore, its attractiveness.

Currency Fluctuations: For funds investing in international assets, currency exchange rates between the fund's base currency and the currencies of the underlying assets can impact its price. A strengthening of the asset's currency relative to the fund's currency may increase the fund's price.
