How do you account for duration and convexity for floating-rate bonds for interpretation and formulae (fixed income, yield curve, duration, conveXity, floating rate, quant)


What is the convexity of a floating rate bond?

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. If a bond’s duration increases as yields increase, the bond is said to have negative convexity.

How do we use duration and convexity to predict bond prices for a change in yield?

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. Convexity relates to the interaction between a bond’s price and its yield as it experiences changes in interest rates.

How do you calculate convexity and duration?

Another way to view it is, convexity is the first derivative of modified duration. By using convexity in the yield change calculation, a much closer approximation is achieved (an exact calculation would require many more terms and is not useful). Using convexity (C) and Dmod then: % Price Chg. = -1 * D mod * Yield Chg.

How do you calculate bond convexity?

Quote from Youtube:
That they put it very simply treats convexity as x squared or specifically convexity is the weighted average of maturity squares of the bond.

Is convexity the derivative of duration?

Convexity is the rate that the duration changes along the yield curve. Thus, it’s the first derivative of the equation for the duration and the second derivative of the equation for the price-yield function or the function for change in bond prices following a change in interest rates.

What does it mean to be long convexity?

From the point of view of risk management, being long convexity (having positive Gamma and hence (ignoring interest rates and Delta) negative Theta) means that one benefits from volatility (positive Gamma), but loses money over time (negative Theta) – one net profits if prices move more than expected, and net loses if …

How does duration affect bond prices?

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). For example, if rates were to rise 1%, a bond or bond fund with a five-year average duration would likely lose approximately 5% of its value.

What is duration and how is it determined determine how the duration of a bond be affected if the coupons were extended over additional time periods?

Determine how the duration of a bond be affected if the coupons were extended over additional time periods. The longer the coupon payments are extended, the greater is the duration, because the investor is more exposed to changes in the required rate of return.

What does bond duration tell you?

Bond duration is a way of measuring how much bond prices are likely to change if and when interest rates move. In more technical terms, bond duration is measurement of interest rate risk. Understanding bond duration can help investors determine how bonds fit in to a broader investment portfolio.

How do you calculate convexity of a bond portfolio?

So convexity ≈ duration2 + dispersion (variance) of maturity. At current rates, they have the same value and the same slope (duration).

How do you interpret a convexity number?

To interpret a convexity number, think of it as being the percent change in modified duration from a 1% change in yield. To estimate what the effect of including convexity in a price change calculation for a 1% change in yield, multiply the convexity by 1%^2=1%*1%.

How do you calculate duration of a bond?

The formula for the duration is a measure of a bond’s sensitivity to changes in the interest rate, and it is calculated by dividing the sum product of discounted future cash inflow of the bond and a corresponding number of years by a sum of the discounted future cash inflow.

How do you use time duration?

We can calculate the duration of an activity if we know the starting and finishing time. For example, if the morning assembly in a school begins at 8:00 a.m. and finishes at 8:25 a.m. the duration of assembly is the difference of finishing time and starting time. 0825 – 800 = 25 minutes.

How do you calculate the duration for a portfolio of bonds?

Portfolio duration is commonly estimated as the market-value-weighted average of the yield durations of the individual bonds in the portfolio. The total market value of the bond portfolio is 170,000 + 850,000 + 180,000 = 1,200,000.

What is the difference between bond duration and maturity?

In plain English, “duration” means “length of time” while “maturity” denotes “the extent to which something is full grown.” When bond investors talk about duration it has a very specific meaning: The sensitivity of a bond’s price to changes in interest rates.

What is positive convexity?

A bond is said to have positive convexity if duration rises as the yield declines. A bond with positive convexity will have larger price increases due to a decline in yields than price declines due to an increase in yields.

What is duration example?

Duration is defined as the length of time that something lasts. When a film lasts for two hours, this is an example of a time when the film has a two hour duration.

How is effective duration calculated?

Effective Duration Calculation



P(0) = the bond’s original price per $100 worth of par value. P(1) = the price of the bond if the yield were to decrease by Y percent. P(2) = the price of the bond if the yield were to increase by Y percent. Y = the estimated change in yield used to calculate P(1) and P(2).

How do you calculate duration of a bond in Excel?

Quote from Youtube:
Select the maturity date put comma and a coupon read sell the coupon rate and put comma and yield is yield to maturity. Select the yield to maturity. And put comma and finally the frequency.

How do you calculate bond duration on a financial calculator?

Quote from Youtube:
And find out the duration. The first thing that I am going to do is I'm going to punch in my payment. Which is going to be $60. Because the coupon rate is 6%. So I punch in six zero.

How do you calculate duration on a calculator?

Quote from Youtube:
Duration is the sum from 1 T equals 1 to n where n is the years to maturity C is the coupon payment.

How does hp12c calculate bond duration?

It is important to note that these equations work only on an interest payment date.
