Stock Market Performance: The overall performance of the Taiwan stock market, particularly the constituent stocks within the ETF's holdings, significantly influences its price.

Underlying Index Movements: 00757.TW tracks a specific index; therefore, fluctuations in that index directly impact the ETF's net asset value (NAV) and market price.

Supply and Demand: Like any security, the ETF's price is determined by the balance of buying and selling pressure in the market.

Investor Sentiment: General investor optimism or pessimism towards the market or the specific sectors represented in the ETF can drive demand and price changes.

News and Events: Significant economic news, company-specific announcements, or geopolitical events affecting the Taiwanese market can influence the ETF's price.

Currency Exchange Rates: Fluctuations in the exchange rate between the Taiwan Dollar (TWD) and other currencies (if the ETF holds foreign assets) can affect its value.

Dividend Payouts: When the ETF distributes dividends, the NAV typically decreases by the dividend amount, which can affect the market price.

Expense Ratio: While not a direct driver of daily price fluctuations, the ETF's expense ratio impacts its long-term performance relative to its benchmark index.

Tracking Error: The ETF's ability to accurately track its underlying index can influence its price relative to the index's performance.
