Underlying Asset Performance: VDTE.MU's price heavily reflects the performance of the technology companies it holds. Gains or losses in those stocks directly impact the ETF's value.

Supply and Demand: Increased investor demand typically pushes the price higher, while higher selling pressure can lead to price declines. Market sentiment significantly influences this.

Currency Fluctuations: As VDTE.MU holds international stocks, currency exchange rates can affect its price. A stronger Euro versus other currencies where the stocks are listed could increase the ETF's value, and vice versa.

Expense Ratio: Although not directly influencing daily price swings, the ETF's expense ratio impacts long-term returns. Higher fees can reduce overall gains compared to similar ETFs.

Geopolitical Events: Global events like political instability, trade wars, or regulatory changes affecting the technology sector can lead to investor uncertainty and price volatility.

Interest Rates: Changes in interest rates can impact the valuations of growth stocks, many of which are found in technology ETFs. Higher rates can make future earnings less attractive, potentially lowering valuations.
