Market Sentiment: Investor confidence and overall market trends significantly influence fund prices. Positive sentiment boosts demand, increasing prices, while negative sentiment leads to selling pressure and price declines.

Fund Performance: The fund's historical and current investment performance directly impacts its attractiveness. Strong returns relative to its benchmark tend to drive demand and increase its price.

Economic Conditions: Macroeconomic factors like interest rates, inflation, and economic growth affect the underlying assets held by the fund, influencing its price. For example, rising interest rates can negatively affect bond prices.

Fund Size: Large fund sizes can sometimes limit the fund's agility in making investment decisions. Extreme increases/decreases in Assets Under Management can impact performance and ultimately the price.

Sector Performance: The performance of the specific sectors and industries in which the fund invests significantly impacts the fund's overall price. For example, the tech industry performance.

Fund Management: The fund manager's skill, experience, and investment strategy play a crucial role in its performance and price. Changes in fund management can also affect investor confidence.

Currency Fluctuations: For funds investing in international assets, exchange rate fluctuations can impact the fund's returns and price when converted back to the base currency (in this case, likely GBP).

Regulatory Changes: Changes in regulations or government policies affecting the fund's investments or the financial market in general can influence investor sentiment and fund prices.

Fund Flows: Large inflows of cash into the fund can increase its price, while significant outflows can put downward pressure on the price as the fund is forced to sell assets.

Expense Ratio: While not directly influencing the daily price, a higher expense ratio can reduce the fund's overall return and potentially affect its long-term attractiveness to investors.
