Underlying Asset Performance: VGVF.XETRA tracks the FTSE Global All Cap ex US index. Therefore, the performance of the underlying stocks in this index directly impacts its price. A rise in the collective value of these stocks leads to an increase in the ETF's price, and vice versa. Supply and Demand: Like any security, the market forces of supply and demand influence VGVF.XETRA's price. Higher demand pushes the price up, while increased selling pressure drives it down. Currency Fluctuations: As the underlying assets are primarily non-US equities, currency exchange rates, particularly between the Euro and other major currencies, significantly affect the ETF's price when translated back into Euro. A stronger Euro against other currencies where the underlying assets are based can cause the ETF price to fall. Expense Ratio and Tracking Error: VGVF.XETRA has an expense ratio. While relatively small, it does affect the overall return. Tracking error, which measures how closely the ETF follows its index, can also influence the difference between the index's performance and the ETF's actual returns. Market Sentiment and Global Economic Conditions: Broad market sentiment and overall global economic factors impact investor appetite for international equities. Positive sentiment and a strong global economy usually drive investments into ETFs like VGVF.XETRA, increasing its price. Conversely, negative sentiment and economic uncertainty can lead to outflows and lower prices.
