Fund Performance: Historical and recent performance dictates investor sentiment and thus, demand. Good returns typically increase price.

Market Conditions: Overall market trends (bullish or bearish) in the underlying assets influence the fund's value. Broad economic conditions too.

Management Fees: Higher management fees reduce net returns, potentially impacting the fund's attractiveness and price.

Underlying Assets: The value of the assets the fund invests in (e.g., stocks, bonds) directly impacts the fund's Net Asset Value (NAV).

Investor Demand: High demand increases the price, especially if supply is limited. Conversely, redemptions can decrease the price.

Interest Rates: Changes in interest rates, particularly if the fund holds bonds, affect the valuation and therefore the price.

Fund Size: Very large funds can struggle to generate above-average returns. Small funds might lack diversification and be more volatile.

Regulatory Changes: New regulations affecting the fund or its underlying investments can impact its perceived risk and hence the price.

Currency Fluctuations: If the fund invests in foreign assets, currency exchange rate fluctuations can affect the fund's return in the investor's currency.
