Market Interest Rates: Rising interest rates typically decrease bond prices, lowering SEMMX's net asset value. Conversely, falling rates usually increase bond prices, boosting the fund's value.

Credit Risk: Deterioration in the creditworthiness of bonds held by SEMMX can lead to lower prices and negatively impact the fund's value. Credit upgrades have the opposite effect.

Economic Conditions: Economic growth generally supports bond prices if inflation remains controlled. However, strong growth can also trigger inflationary concerns, leading to higher interest rates and lower bond values.

Inflation Expectations: Rising inflation expectations tend to push interest rates higher, causing bond prices (and SEMMX's value) to decline. Low or falling inflation expectations have the opposite effect.

Supply and Demand: Increased demand for short-term municipal bonds can drive up their prices, benefiting SEMMX. Conversely, increased supply or reduced demand can lower prices.

Municipal Bond Market Conditions: Factors specific to the municipal bond market, such as tax law changes, state and local government fiscal health, and investor sentiment, can affect municipal bond prices.

Fund Management: The investment strategies and expertise of SEMMX's fund managers play a role in selecting securities and managing risk, potentially impacting the fund's performance and price.

Tax Law Changes: Changes to tax laws affecting municipal bond interest income can significantly alter the attractiveness of municipal bonds, influencing demand and therefore prices.
