Underlying Asset Performance: The ETF's price closely tracks the performance of the underlying index it aims to replicate. Positive index performance usually leads to price increases, and vice versa.

Supply and Demand: Increased investor demand typically drives the price upward, while higher selling pressure can lower it.

Expense Ratio: The fund's operating costs, which are deducted from the fund's assets, indirectly affect its returns and thus its price.

Tracking Error: How closely the ETF mirrors its benchmark index influences price. Significant deviation can lead to pricing discrepancies.

Currency Fluctuations: If the underlying assets are denominated in a different currency, exchange rate variations can affect the ETF's price in EUR.

Market Sentiment: Overall investor confidence or fear in the market can impact trading volume and ETF price.

Interest Rates: Changes in interest rates can affect the attractiveness of ETFs compared to other investment options.

Dividend Payments: Dividends paid by the underlying securities are reflected in the ETF's price after distribution.
