Underlying Index Performance: 00674R.TW tracks the performance of a specific underlying index. If the index rises, the ETF price will likely increase, and vice versa.

Supply and Demand: Basic economics apply. Higher demand for the ETF than supply can drive up its price, while excess supply can lower it.

Net Asset Value (NAV): The NAV represents the total value of the ETF's holdings divided by the number of outstanding shares. The ETF price should ideally closely track the NAV.

Market Sentiment: Overall investor confidence and market optimism/pessimism can influence ETF trading activity and price.

Expense Ratio: The ETF's expense ratio (annual management fee) indirectly impacts the price. Higher expenses can slightly reduce returns over time.

Currency Exchange Rates: Fluctuations in the exchange rate between the local currency and the currencies of the underlying assets can affect the ETF's price.

Trading Volume and Liquidity: Higher trading volume generally implies better liquidity, leading to tighter bid-ask spreads and potentially more efficient pricing.

Changes in Interest Rates: Changes in interest rates may affect the attractiveness of the assets in the underlying index, thus affecting the ETF price.
