Underlying Index Performance: The primary driver is the performance of the MSCI World Health Care Index, which XDWH.DU aims to track. Positive returns in the index typically lead to higher ETF prices.

Supply and Demand: Basic economics apply. Increased demand for XDWH.DU units relative to supply pushes prices up, while increased supply relative to demand lowers prices.

Currency Exchange Rates: Since the underlying assets are likely priced in currencies other than EUR (XDWH.DU's trading currency), fluctuations in exchange rates, particularly between EUR and USD, impact the ETF's price.

Management Fees and Expenses: While these don't directly cause daily price swings, higher fees gradually erode returns, potentially making the ETF less attractive over the long term and affecting its relative price versus competitors.

Investor Sentiment: Broad market sentiment towards healthcare stocks, influenced by factors like regulatory changes, pharmaceutical innovation, and demographic trends, can affect demand for XDWH.DU.

Dividend Payments: XDWH.DU may distribute dividends, which slightly reduces the ETF's price on the ex-dividend date. The dividend yield influences investor demand.

Tracking Error: The ETF's ability to accurately replicate the index also affects its price. Higher tracking error can make the ETF less desirable and lower its price.

Overall Market Conditions: General economic conditions and market volatility can influence investor appetite for riskier assets like sector-specific ETFs, impacting XDWH.DU's price.
