Underlying Index Performance: The primary driver is the performance of the stocks within the S&P 500 ESG index that S5SG.F tracks.

Supply and Demand: Market demand for the ETF itself influences its price, as higher demand can push the price up and vice versa.

Expense Ratio and Management Fees: The ETF's internal costs, such as the expense ratio, can slightly impact returns and indirectly affect price.

Trading Volume and Liquidity: Higher trading volume generally leads to tighter bid-ask spreads and more efficient price discovery.

Market Sentiment: Overall investor sentiment towards ESG (Environmental, Social, and Governance) investing can influence demand for the ETF.

Currency Exchange Rates: Fluctuations in the exchange rate between the ETF's base currency and other currencies can affect its price for international investors.

Interest Rates: Changes in interest rates can impact the valuation of underlying stocks and, consequently, the ETF's price.

Economic Conditions: Broad economic factors like GDP growth, inflation, and unemployment can influence corporate earnings and stock prices, affecting the ETF.

Regulatory Changes: New regulations related to ESG investing or financial markets can impact investor behavior and ETF prices.
