Positive stock performance drives the ETF price up, and vice versa. Supply and Demand: Market forces of supply and demand influence the ETF's price. High demand relative to supply pushes the price higher, while increased selling pressure lowers it. Investor Sentiment: Overall market optimism or pessimism towards Taiwanese equities impacts the ETF's price. Positive sentiment leads to increased buying, driving prices up. Index Tracking Accuracy: Deviations from the underlying index's performance can affect the ETF's price. Effective tracking maintains a closer correlation. Management Fees and Expenses: Higher management fees and operational expenses can slightly reduce the ETF's return, potentially impacting its price over time. Currency Exchange Rates: Fluctuations in the exchange rate between the Taiwan dollar and other currencies can affect the ETF's price for international investors.
