Underlying Index Performance: The primary driver is the performance of the index 371450.KO tracks. If the index rises, the ETF's price generally rises, and vice versa.

Supply and Demand: Market forces of supply and demand influence the ETF's price. High demand relative to supply can push the price up, while the opposite lowers it.

Net Asset Value (NAV): The NAV is the per-share value of the ETF's holdings. The market price should closely track the NAV, but discrepancies can occur.

Expense Ratio: While not directly affecting daily price fluctuations, a higher expense ratio slowly erodes returns, influencing long-term performance and indirectly affecting price.

Trading Volume and Liquidity: Higher trading volume and liquidity usually lead to tighter bid-ask spreads and more efficient price discovery.

Market Sentiment: Overall investor sentiment towards the market sector or asset class the ETF represents influences buying and selling pressure.

Economic Conditions: Broad economic factors like interest rates, inflation, and economic growth can affect the underlying assets and, therefore, the ETF's price.
