Global Equity Market Performance: The IOO.AU ETF tracks a global index. Strong performance in major global equity markets (e.g., US, Europe, Japan) will likely increase its price.

Currency Fluctuations: As the ETF holds international assets, changes in the AUD/USD exchange rate significantly impact returns. A weaker AUD increases the AUD value of USD-denominated assets.

Index Rebalancing: Periodic index rebalancing can cause the ETF to buy or sell holdings, influencing demand and potentially affecting the price, especially if significant changes occur.

Investor Sentiment: Overall market sentiment and risk appetite affect demand for the ETF. Positive sentiment drives inflows and price increases; negative sentiment leads to outflows and price decreases.

Dividend Payments: When underlying companies pay dividends, the ETF accumulates these. While dividends don't directly affect the immediate price, they contribute to overall returns and attractiveness.

Management Fees & Expenses: Higher fees can slightly dampen overall returns, indirectly affecting the ETF's price compared to a hypothetical zero-fee alternative, although the impact is usually minimal.

Supply and Demand for IOO.AU Shares: Basic supply and demand principles apply. Increased buying pressure raises the price, while increased selling pressure lowers it.

Economic Data Releases: Major economic data releases (e.g., inflation reports, GDP figures) can influence market sentiment and, consequently, the ETF's price if the underlying companies are affected.
