Economy: Economic growth typically drives higher bond yields, lowering bond prices including FRDUZX.US. Conversely, recessions tend to lower yields and increase bond prices.

Interest Rates: The Federal Reserve's interest rate policy is paramount. Higher rates make existing bonds less attractive, decreasing their prices, and vice-versa.

Inflation: Rising inflation erodes the purchasing power of future fixed income payments, prompting investors to demand higher yields and pushing bond prices down.

Credit Risk: Changes in the perceived creditworthiness of the bond issuers within FRDUZX.US directly impact its price. Downgrades often lead to price declines.

Supply and Demand: Increased supply of similar bonds puts downward pressure on prices. Higher demand from investors drives prices upward.

Maturity Date: Generally, bonds with longer maturities are more sensitive to interest rate changes, affecting their price volatility.

Market Sentiment: Overall investor risk appetite plays a role. In risk-off environments, investors may flock to bonds, boosting prices, and vice-versa.
