Taiwan Stock Market Performance: EWT's price largely mirrors the overall performance of the Taiwan Stock Exchange (TWSE). Positive market sentiment and rising stock prices in Taiwan typically lead to an increase in EWT's value.

Currency Exchange Rates: Fluctuations in the exchange rate between the US dollar and the New Taiwan dollar (TWD) affect EWT's price. A stronger TWD relative to the USD boosts EWT's value when the underlying Taiwanese stocks are converted back to USD.

Sector Performance: The performance of key sectors within the Taiwanese economy, such as technology (especially semiconductors), can significantly impact EWT. Positive earnings or outlooks in these sectors can drive EWT's price higher.

Global Economic Conditions: Global economic growth, trade relations (particularly between Taiwan and major economies like the US and China), and geopolitical events all influence investor sentiment towards Taiwanese equities and, consequently, EWT.
