Underlying Asset Performance: The ETF's price closely tracks the performance of the stocks within its underlying index, the Solactive Sustainable Japan SRI Index. Strong performance of these companies generally leads to a higher ETF price. Supply and Demand: Market forces of supply and demand directly impact the ETF price. Higher demand than supply can push the price up, while increased supply over demand may lower it. Investor Sentiment: Overall market sentiment towards Japanese stocks and socially responsible investing (SRI) can influence demand and price. Positive sentiment tends to drive up prices. Index Changes: Changes in the composition or weighting of stocks within the Solactive Sustainable Japan SRI Index can affect the ETF's price as the fund manager adjusts holdings to reflect the updated index. Expense Ratio: While it doesn't directly fluctuate the price, the ETF's expense ratio (ongoing charges) impacts overall returns, thus affecting investor perception and long-term price trajectory. Foreign Exchange Rates: Currency fluctuations, specifically the Yen/Euro exchange rate, play a role because the underlying assets are Japanese stocks traded in Yen, while the ETF is priced in Euro. Tracking Error: The degree to which the ETF's performance deviates from the Solactive Sustainable Japan SRI Index impacts investor confidence and therefore price. Lower tracking error is generally favored.
