Underlying Index Performance: The ETF's price heavily depends on how the underlying KOSPI 200 index performs. Positive index movements generally raise the ETF price, while negative movements lower it.

Supply and Demand: Increased demand for the ETF pushes its price up, while increased supply pushes it down. Market sentiment and investor confidence significantly influence supply and demand.

Net Asset Value (NAV): The NAV, representing the collective value of the ETF's holdings, serves as a benchmark. The ETF price typically trades close to its NAV, but deviations can occur.

Expense Ratio: The ETF's annual expense ratio, which covers management fees and other operational costs, can slightly affect its returns over time, impacting its price indirectly.

Dividend Payments: Dividends from the underlying stocks held by the ETF are distributed to ETF holders. These dividend payments can influence the ETF's overall return and, consequently, its price.

Currency Exchange Rates: Fluctuations in the exchange rate between the Korean Won and other currencies, particularly the US dollar, can affect the ETF's price, especially for international investors.

Market Sentiment: Overall market optimism or pessimism can impact investor appetite for ETFs, including 169950.KO. This sentiment drives trading activity and affects the ETF's price.

Economic Factors: Macroeconomic factors such as interest rates, inflation, and economic growth in South Korea can influence the performance of the companies in the KOSPI 200 and, consequently, the ETF's price.
