Underlying Asset Performance: The ETF's price is primarily driven by the collective performance of the companies within its underlying index. If these companies perform well, the ETF's price generally rises, and vice versa.

Supply and Demand: Like any security, the ETF's price fluctuates based on buying and selling pressure. High demand typically leads to price increases, while increased selling pressure can lower the price.

Market Sentiment: Overall market conditions and investor confidence can influence the ETF's price. Positive market sentiment tends to support higher prices, while negative sentiment can lead to price declines.

Expense Ratio: The ETF's annual operating expenses, expressed as a percentage of assets, can indirectly affect its price by reducing the overall return to investors.

Tracking Error: The difference between the ETF's performance and the performance of its underlying index is known as tracking error. Larger tracking error can negatively affect investor perception and potentially impact the price.

Currency Fluctuations: Since it is a KO ETF, currency exchange rates between the Korean Won and other currencies, especially if the underlying assets have some exposure to international markets or their revenues are affected by international demand, impact the price.
