Market Interest Rates: Rising interest rates typically decrease bond prices, including those held by FMITX.US, as newly issued bonds offer higher yields.

Credit Risk: Changes in the creditworthiness of the bond issuers within the FMITX.US portfolio can affect its value. Downgrades lead to price declines.

Inflation Expectations: Higher inflation expectations usually reduce bond prices because investors demand higher yields to compensate for the eroding purchasing power of future payments.

Economic Growth: Strong economic growth might lead to expectations of higher interest rates, which can negatively impact the fund's value.

Fund Management: The skill of the fund manager in selecting and managing bond holdings impacts the fund's performance and therefore its price.

Supply and Demand: Increased demand for FMITX.US can drive up its price, while increased selling pressure can lower it.

Fund Expenses: Higher expense ratios can slightly reduce the fund's net asset value, potentially affecting its market price over time.
