Interest Rate Movements: Rising interest rates typically cause bond prices, and thus VSZEX's NAV, to decline, and vice versa.

Credit Quality of Holdings: Downgrades in credit ratings of bonds held by VSZEX can negatively impact its price.

Inflation Expectations: Higher inflation expectations usually lead to lower bond prices and potentially lower VSZEX value.

Market Liquidity: Reduced market liquidity can widen bid-ask spreads and affect the fund's trading price.

Fund Flows: Significant outflows from VSZEX may force the fund to sell assets, potentially lowering prices.

Economic Growth: Strong economic growth may lead to higher interest rates and thus lower VSZEX value, while weaker growth may support bond prices.

Maturity and Duration: VSZEX's average maturity and duration affect its sensitivity to interest rate changes; longer durations imply greater price volatility.

Supply and Demand: Overall supply and demand for short-term bond funds influence VSZEX's price.

Federal Reserve Policy: Actions by the Federal Reserve, such as quantitative easing or tightening, can significantly affect bond yields and VSZEX's value.
