Underlying Asset Performance: The primary driver is the performance of the underlying assets held by the fund. Positive returns in these assets generally lead to a price increase.

Supply and Demand: Market forces of supply and demand influence the fund's price. Higher demand relative to supply can push the price upward, and vice versa.

Net Asset Value (NAV): NAV is the per-share value of the fund's assets. The market price usually tracks the NAV closely, though deviations can occur.

Market Sentiment: Overall investor confidence and sentiment towards the asset class or sector the fund invests in can affect its price.

Expense Ratio: While it doesn't directly impact the daily price, a higher expense ratio can reduce long-term returns, making it less attractive compared to similar funds.

Fund Management: The skill and effectiveness of the fund's management team in selecting and managing investments influence performance and, subsequently, price.

Economic Conditions: Broad economic factors such as interest rates, inflation, and economic growth can indirectly affect the value of the fund's underlying assets.
