Market Sentiment: General investor risk appetite and overall market sentiment can impact bond prices. Risk-averse investors may flock to bonds, increasing demand and prices. Conversely, a risk-on environment might lead to selling pressure.

Maturity and Duration: Bonds with longer maturities and higher durations are generally more sensitive to interest rate changes, meaning their prices will fluctuate more.

Supply and Demand: The relative supply of and demand for bonds in general can influence WCGABX.US's price. Higher demand tends to increase prices, while increased supply can decrease them.
