**Underlying Index Performance**: The primary driver is the performance of the index 379800.KO tracks. If the index constituents rise, the ETF price tends to rise, and vice versa.

**Supply and Demand**: Increased investor demand generally pushes the price higher, while increased selling pressure lowers it. This is influenced by market sentiment and overall investment appetite.

**Expense Ratio & Trading Costs**: The ETF's expense ratio and brokerage fees impact the overall return and affect investor decisions, potentially influencing demand.

**Market Sentiment**: Broad market conditions and investor confidence significantly impact ETF prices. Positive sentiment leads to increased investment, while negative sentiment prompts selling.

**Currency Fluctuations**: For ETFs investing in foreign assets, currency exchange rates play a role. A stronger local currency relative to the foreign currencies can positively impact returns.

**Economic Data Release**: Major economic reports can trigger market volatility, leading to price swings in the ETF. Positive data usually drives demand, while negative data can lead to selling.

**Dividend Distributions**: Dividends paid by the companies within the underlying index can contribute to the ETF's overall return and attract investors.

**Interest Rate Changes**: Interest rate hikes often lead to reduced investment in equities, potentially impacting ETF prices. Conversely, rate cuts can stimulate the market.
