Constituent Stock Prices: The ETF's price mirrors the weighted average price of its underlying stocks within the Taiwan 50 index. Higher stock prices generally lead to a higher ETF price.

Supply and Demand: Increased demand pushes the price up, while increased supply lowers it. Trading activity significantly impacts short-term price fluctuations.

Market Sentiment: Overall investor confidence and economic outlook influence buying and selling decisions, impacting the ETF's price.

Dividend Distributions: Upcoming dividend payouts can attract buyers, temporarily increasing the ETF's price before the ex-dividend date.

Expense Ratio: Although indirectly, the expense ratio affects returns. Higher expense ratios can slightly suppress the ETF's long-term performance and attractiveness.

Tracking Error: The ETF aims to replicate the index, but deviations (tracking error) can exist due to management fees or sampling techniques, affecting the ETF's alignment with the underlying index return.
