Underlying Index Performance: VIGI's price closely mirrors the performance of its underlying index, the MSCI International High Dividend Yield Index. Positive returns in the index typically lead to VIGI's price increase.

Currency Fluctuations: As VIGI invests in international stocks, currency exchange rates significantly impact its USD-denominated price. A stronger USD can decrease the value of foreign holdings, and vice versa.

Dividend Yield Changes: Variations in the dividend yields of the stocks held within the index can affect VIGI's perceived value and consequently, its price. Higher dividend yields may attract investors, pushing the price up.

Interest Rate Movements: Changes in global interest rates influence the attractiveness of dividend-paying stocks. Higher interest rates may make bonds more appealing, potentially reducing demand for VIGI and lowering its price.

Market Sentiment: Overall market sentiment, particularly towards international equities and dividend-focused investments, affects VIGI's price. Positive market sentiment often drives demand, increasing the ETF's price.

Expense Ratio and Trading Costs: VIGI's expense ratio and brokerage trading costs reduce overall returns. Higher costs can make it less attractive compared to similar ETFs, potentially influencing its price negatively.

Supply and Demand: Like any exchange-traded fund, VIGI's price is subject to basic supply and demand. Increased buying pressure elevates the price, while greater selling pressure can depress it.
