Investment performance: The fund's net asset value (NAV) fluctuates based on the underlying investments' performance, particularly bonds. Higher bond values lead to increased NAV.

Interest rate changes: Rising interest rates typically decrease bond prices, lowering the fund's NAV. Conversely, falling rates tend to increase NAV.

Credit risk: Downgrades or defaults within the fund's bond holdings can negatively impact its value, lowering the NAV.

Fund management: Decisions made by the fund manager, such as security selection and duration management, influence overall performance.

Expense ratio: The fund's expense ratio impacts returns. Higher expenses reduce net returns, affecting the fund's price.

Market conditions: Broad economic factors, such as inflation and recessionary fears, can affect bond market sentiment and influence the fund's price.

Investor demand: High demand for the fund may temporarily increase its trading price relative to its NAV, creating a premium. The opposite happens with low demand.
