Underlying Index Performance: DSUS.PA tracks an index, so its price closely mirrors the performance of the underlying assets in that index. Positive index returns typically increase the ETF price, while negative returns decrease it.

Supply and Demand: Basic economics apply. High demand for DSUS.PA relative to available supply will push the price up. Conversely, increased selling pressure and low demand will cause the price to fall.

Expense Ratio and Fees: The expense ratio, and any other fees associated with the ETF, indirectly affect the price. Higher fees can reduce overall returns, potentially making the ETF less attractive and influencing its price negatively in the long term.

Currency Fluctuations: If the underlying assets of DSUS.PA are denominated in a different currency, fluctuations in the exchange rate between that currency and the Euro can impact the ETF's price.

Interest Rates: Changes in interest rates can affect the attractiveness of dividend-paying stocks held within the ETF. Higher rates may make bonds more appealing, potentially reducing demand for the ETF and its price.
