Investment Performance: Historical and current investment performance directly influences investor demand and thus the price. Strong performance typically leads to increased demand and a higher price.

Market Conditions: Overall market trends, economic indicators (GDP growth, inflation), and investor sentiment significantly affect fund prices. Positive market environments usually lead to price appreciation.

Fund Holdings: The underlying assets held by the fund (stocks, bonds, etc.) drive its value. The performance of these individual assets directly impacts the overall fund price.

Fund Management: The expertise and effectiveness of the fund manager in selecting and managing investments play a crucial role. A skilled manager can generate better returns and attract investors.

Expense Ratio: The fund's expense ratio (management fees, operating expenses) can affect its attractiveness. Lower expense ratios are generally favored, as they result in higher net returns for investors.

Investor Demand: High demand for the fund leads to price increases, while low demand can result in price decreases. Investor sentiment and preferences play a key role in this aspect.

Currency Fluctuations: If the fund invests in international assets, currency exchange rates can impact the fund's value when translated back to the base currency (GBP in this case).
