Underlying Asset Performance: The price of FID.US ETFs closely tracks the performance of the underlying assets they hold. A rise in the value of these assets generally pushes the ETF price up.

Supply and Demand: Market supply and demand for the ETF shares influences its price. Higher demand relative to supply tends to drive prices upward, and vice versa.

Net Asset Value (NAV): The ETF's NAV, calculated based on the market value of its underlying holdings, serves as a benchmark. Market price deviates around this theoretical value.

Expense Ratio: The ETF's expense ratio, reflecting the annual cost of managing the fund, indirectly affects the long-term return and price appreciation.

Interest Rates: Changes in interest rates can affect the attractiveness of fixed-income ETFs within FID.US, and impact the valuations of underlying equity investments.

Market Sentiment: General market sentiment, whether bullish or bearish, can impact investor demand for ETFs and thus influence their price, irrespective of NAV.
