Fund Performance: How well the fund's investments perform directly impacts its Net Asset Value (NAV), the basis for its price. Strong returns lead to higher prices.

Market Conditions: Overall market trends (bull or bear markets) and sector-specific performance influence the underlying assets held by the fund, thus affecting its price.

Investor Sentiment: Demand for the fund affects its price. High demand can drive prices up, while increased selling pressure can push them down.

Currency Fluctuations: For funds investing in international assets, exchange rate changes between the fund's base currency and the currencies of the assets impact the fund's value.

Economic Data: Macroeconomic indicators like GDP growth, inflation, and interest rates influence the performance of companies and markets, affecting the fund's investments.

Fund Management Strategy: Changes in investment strategy or the fund manager can affect investor confidence and, consequently, the fund's price.

Expense Ratio: Higher expense ratios can reduce overall returns and potentially impact the fund's price compared to similar, lower-cost funds.

Fund Size and Liquidity: A very large fund might be harder to manage effectively, while a fund with low liquidity can experience price volatility due to fewer buyers and sellers.
