Underlying Asset Performance: The price of XWTS.F largely mirrors the performance of the underlying securities within the MSCI World Index. Gains or losses in these global stocks directly impact the ETF's value.

Currency Fluctuations: As XWTS.F tracks a global index, currency exchange rates between the Euro and other currencies (particularly the US dollar, Japanese Yen, etc.) influence returns. A stronger Euro can negatively impact returns when foreign assets are converted back.

Supply and Demand: Market demand for XWTS.F units can affect its price. High demand can push the price slightly above its net asset value (NAV), while increased selling pressure can depress it.

Interest Rates: Changes in global interest rate environments, particularly those set by major central banks, influence investor sentiment and potentially drive flows in or out of equities, affecting XWTS.F.

Expense Ratio: The expense ratio charged by the ETF provider reduces the overall returns, impacting the long-term growth of the investment.

Market Sentiment: Overall global market sentiment, influenced by macroeconomic factors, geopolitical events, and investor confidence, can drive broad buying or selling of equities, impacting XWTS.F regardless of individual company performance.
