Inflation Expectations: Higher inflation expectations tend to push interest rates upward, decreasing bond values, while lower inflation expectations can lead to lower rates and higher bond prices.

Fund Flows: Significant inflows into the fund can drive up its price, while large outflows can put downward pressure on it.

Maturity of Holdings: Funds with longer-dated bonds are more sensitive to interest rate changes than those with shorter-dated bonds.
