Fund Performance: The fund's past performance directly impacts investor demand. Strong returns attract more investments, driving up the fund's price, while poor performance can lead to outflows and price decreases.

Market Conditions: Overall market sentiment and economic conditions significantly influence fund prices. A bullish market typically supports higher fund values, while a bearish market can cause declines.

Underlying Assets: The value of the assets held within the fund, such as stocks or bonds, dictates the fund's net asset value (NAV). Changes in the prices of these underlying assets directly affect the fund's price.

Expense Ratio: The fund's expense ratio, which includes management fees and other operating costs, can impact returns. Higher expense ratios reduce returns, potentially affecting the fund's attractiveness and price.

Investor Sentiment: General investor mood and expectations play a role. Positive sentiment can boost demand, increasing the price, whereas negative sentiment can lead to sell-offs and price drops.

Interest Rates: Changes in interest rates can affect the value of bond holdings within the fund. Rising rates generally decrease bond values, potentially lowering the fund's price.

Currency Exchange Rates: For funds holding assets denominated in foreign currencies, fluctuations in exchange rates can impact the fund's value when converted back to the base currency.

Fund Flows: Inflows of new capital into the fund can increase demand and potentially raise the price. Conversely, outflows can put downward pressure on the price as the fund sells assets to meet redemptions.
