Underlying Assets Performance: The ETF's price heavily relies on the performance of its underlying assets. Strong performance drives the ETF price up; weak performance pulls it down.

Supply and Demand: Increased demand usually raises the price. Higher supply relative to demand decreases the price. Trading volume also plays a role.

Market Sentiment: Overall investor confidence or fear can impact the prices of all ETFs, including this one, reflecting broader market trends.

Interest Rates: Changes in interest rates can influence investment choices, impacting the attractiveness of ETFs like ISZXF.US relative to other investments.

Economic Conditions: Broad economic factors such as GDP growth, inflation, and employment rates can influence investor confidence and impact investment decisions.

Currency Fluctuations: As it's a US-traded ETF, currency exchange rates can affect returns, especially if the underlying assets are held in other currencies.

Fund Management: The fund's investment strategy and management effectiveness influence returns, which affects the ETF's value.

Expense Ratio: The ETF's expense ratio impacts returns. Lower expense ratios translate into higher returns for investors, and can influence the ETF price.
