Expense Ratio: While not directly influencing daily price fluctuations, the ETF's expense ratio reduces overall returns over time.

Interest Rates: Higher interest rates can make bond yields more attractive, potentially drawing investors away from equity ETFs like AIA.US.

Market Sentiment: Overall investor confidence or fear in the market can significantly affect trading activity and, subsequently, ETF prices.

Currency Fluctuations: If the underlying assets are in foreign currencies, changes in exchange rates will impact the ETF's USD value.

Economic Conditions: Economic indicators such as GDP growth, inflation, and unemployment can influence stock valuations and AIA.US price.

Fund Flows: Large inflows of capital into the ETF can increase demand, while outflows can create selling pressure.
