Fund Performance: Stronger historical returns and positive fund manager ratings tend to increase demand, driving the price up. Conversely, poor performance can lead to outflows and price declines.

Market Conditions: Overall market sentiment, economic growth, and interest rate changes significantly influence investor behavior. Bull markets often lift fund prices, while bear markets pressure them downward.

Expense Ratio & Fees: Higher expense ratios and other fund-related fees can detract from returns and negatively impact the fund's appeal, potentially lowering its price relative to similar funds.

Fund Size & Liquidity: A larger fund size may provide economies of scale, but excessive size could hinder flexibility. High liquidity allows for easy buying and selling, typically supporting price stability.

Investor Demand: Increased demand for the fund's investment strategy or sector can push the price higher. Decreased demand can result in price reductions as investors sell their shares.
