Calculating Weighted Duration of a Portfolio Bond portfolio managers must measure the duration of the entire portfolio, and to do that they measure the weighted average of the durations of the individual bonds that comprise the portfolio. The formula for calculating the duration of a portfolio is: ...
A recent paper proposed a new formula for the duration of a portfolio of vanilla bonds. The formula gives a precise, accurate value for any parallel shift in a flat yield curve, without the need for auxiliary concepts. The analysis is performed in the complex plane, and uses all possible ...

In addition, the manager estimates a convexity of 34.51 for portfolio ASD and 36.00 for portfolio BTE. Assuming continuous compounding, which of the following are the best estimates of the decrease in the values of the two portfolios due to the combined effects of duration and convexity? 选项:...
Duration helps you understand, at a glance, how sensitive your bond portfolio is to interest rate changes. Shorter duration bonds will be relatively price stable; they will pay out most of their promised cash flow in the near future. Longer duration bonds are less stable; long duration bonds ...
A formula that attempts to explain a change in thepriceof abondas a function of a change ininterest rates. It is based on the assumption that rises in interest rates depress bond prices and drops in rates do the opposite. It is calculated as: ...
Modified duration measures the average cash-weightedterm to maturityof a bond. It is a very important number for portfolio managers,financial advisors, and clients to consider when selecting investments because—all other risk factors equal—bonds with higher durations have greater pricevolatilitythan bo...
The Macaulay duration is the weighted average term to maturity of the cash flows from a bond, and is frequently used by portfolio managers who use an immunization strategy. The modified duration of a bond is an adjusted version of the Macaulay duration and is used to calculate t...
