Duration of a bond is a measure of its sensitivity to interest rate changes.

• Duration measures the weighted average time it takes for a bond's cash flows to repay its price.

• It helps investors understand how much the bond's price will change in response to interest rate movements.

• Longer duration bonds are more sensitive to interest rate changes than shorter duration bonds.

• Duration is expressed in years and can be used to...read more

Convexity of a bond measures the sensitivity of its duration to changes in interest rates.

• Convexity helps investors understand how the price of a bond will change in response to interest rate movements.

• It provides a more accurate estimate of the bond's price sensitivity compared to duration alone.

• Higher convexity means the bond's price is more sensitive to interest rate changes.

• Convexity is important for managing inter...read more
