Market Interest Rates: Rising interest rates generally cause bond prices to fall, decreasing FHZEX's value. Conversely, falling rates usually boost bond prices, increasing its value.

Credit Risk: Downgrades in the credit ratings of bonds held by FHZEX can lead to price declines. Higher credit risk translates to lower bond prices, affecting the fund's net asset value negatively.

Inflation Expectations: Higher inflation erodes the purchasing power of future bond payments, leading investors to demand higher yields and lower bond prices. FHZEX is affected as inflation rises.

Economic Growth: Strong economic growth can lead to higher interest rates, impacting bond prices negatively. Weaker growth may lead to lower rates, benefiting bond prices and FHZEX's value.

Fund Management: The skill and strategy of the fund managers play a crucial role in selecting bonds and managing risk, directly impacting the fund's returns and overall price performance.
