 # Question: What Is Effective Duration?

## How is duration calculated?

The Macaulay Duration formula reflects the fact that Duration = Present value of a bond’s cash flows, weighted by the length of time to receipt, and divided by the bond’s current market value..

## What is key rate duration?

Key rate duration measures how the value of a security or portfolio changes at a specific maturity point along the entirety of the yield curve. When keeping other maturities constant, the key rate duration can be used to measure the sensitivity in a security’s price to a 1% change in yield for a specific maturity.

## What is duration example?

Duration is an approximate measure of a bond’s price sensitivity to changes in interest rates. … For example, a bond with 10 years till maturity and a 7% coupon trading at par to yield 7% has a duration of 7.355 years. At a yield of 6% (price 107 14/32), its duration is 7.461 years.

## Which bond has the longest duration?

zero-coupon bondA zero-coupon bond has the highest duration among the bonds of the same…

## What is convexity risk?

Convexity is a risk-management tool, used to measure and manage a portfolio’s exposure to market risk. Convexity is a measure of the curvature in the relationship between bond prices and bond yields. Convexity demonstrates how the duration of a bond changes as the interest rate changes.

## Is effective duration measured in years?

Duration is measured in years. Generally, the higher the duration of a bond or a bond fund (meaning the longer you need to wait for the payment of coupons and return of principal), the more its price will drop as interest rates rise.

## What is money duration?

The money duration of a bond is a measure of the price change in units of the currency in which the bond is denominated. Money duration can be stated per 100 of par value or in terms of the bond’s actual position size in the portfolio. In the United States, money duration is commonly called “dollar duration.”

## What is the difference between duration and Macaulay duration?

The Macaulay duration calculates the weighted average time before a bondholder would receive the bond’s cash flows. Conversely, modified duration measures the price sensitivity of a bond when there is a change in the yield to maturity.

## Is convexity good or bad?

In summary: high, absolute, positive convexity is most likely desirable while high, absolute, negative convexity is most likely less desirable given stable or falling interest rates. … negative convexity, most likely, will imply that bond has embedded option. i.e. bond holder sells call option to bond issuer.

## What is duration to worst?

Modified Duration to Worst—Yield change calculated to the priced to worst date; generally used to reflect the behavioral characteristics of a bond as of a specific price/yield and date; consistent with industry calculations, always calculated to the priced to worst date, including all call features.

## Is higher or lower duration better?

In general, the higher the duration, the more a bond’s price will drop as interest rates rise (and the greater the interest rate risk). As a general rule, for every 1% change in interest rates (increase or decrease), a bond’s price will change approximately 1% in the opposite direction, for every year of duration.

## What is Dollar duration?

The dollar duration measures the dollar change in a bond’s value to a change in the market interest rate. The dollar duration is used by professional bond fund managers as a way of approximating the portfolio’s interest rate risk.

## What means duration?

1 : continuance in time gradually increase the duration of your workout. 2 : the time during which something exists or lasts were there for the duration of the concert.

## Can duration be more than maturity?

The duration of any bond that pays a coupon will be less than its maturity, because some amount of coupon payments will be received before the maturity date. … The higher a bond’s coupon, the shorter its duration, because proportionately more payment is received before final maturity.

## How do I calculate duration in Excel?

Another simple technique to calculate the duration between two times in Excel is using the TEXT function:Calculate hours between two times: =TEXT(B2-A2, “h”)Return hours and minutes between 2 times: =TEXT(B2-A2, “h:mm”)Return hours, minutes and seconds between 2 times: =TEXT(B2-A2, “h:mm:ss”)

## How do you calculate dv01 from time?

For example, if the modified duration of a Treasury security is 6.23 years, the DV01 of the instrument is: [ (0.01 x Modified Duration) x Price ] x 0.01 = DV01 [ (0.01 x 6.23) x \$108,593.75 ] x 0.01 = \$67.65 If you break down the formula, you find three components: a.

## What does Modified duration tell us?

Modified duration is a formula that expresses the measurable change in the value of a security in response to a change in interest rates. Modified duration follows the concept that interest rates and bond prices move in opposite directions.

## What is effective duration vs modified duration?

While effective duration is a more complete measure of a bond’s sensitivity to interest rate movements versus the Macauley or modified duration measures, it still falls short because it is a linear approximation for small changes in yield; that is, it assumes that duration stays the same along the yield curve.

## What is duration used for?

Duration and convexity are two tools used to manage the risk exposure of fixed-income investments. Duration measures the bond’s sensitivity to interest rate changes. … With coupon bonds, investors rely on a metric known as duration to measure a bond’s price sensitivity to changes in interest rates.
