bndtotalreturn

Total return of fixed-coupon bond

Syntax

[BondEquiv,EffectiveRate] = bndtotalreturn(Price,CouponRate,Settle,Maturity,ReinvestRate)
[BondEquiv,EffectiveRate] = bndtotalreturn(___,Name,Value)

Description

example

[BondEquiv,EffectiveRate] = bndtotalreturn(Price,CouponRate,Settle,Maturity,ReinvestRate)calculates the total return for fixed-coupon bonds to maturity or to a specific investment horizon.

[BondEquiv,EffectiveRate] = bndtotalreturn(___,Name,Value) adds optional name-value pair arguments.

Use bndtotalreturn to compute the total return for a fixed-coupon bond, given an investment horizon date.

Define fixed-coupon bond.

Price = 101;
CouponRate = 0.05;
Settle = '15-Nov-2011';
Maturity = '15-Nov-2031';
ReinvestRate = 0.04;

Calculate the total return to maturity.

[BondEquiv, EffectiveRate] = bndtotalreturn(Price, CouponRate, ...
Settle, Maturity, ReinvestRate)
BondEquiv = 0.0460
EffectiveRate = 0.0466

Specify an investment horizon.

HorizonDate = '15-Nov-2021';
[BondEquiv, EffectiveRate] = bndtotalreturn(Price, CouponRate, ...
Settle, Maturity, ReinvestRate, 'HorizonDate', HorizonDate)
BondEquiv = 0.0521
EffectiveRate = 0.0528

Perform scenario analysis on the reinvestment rate.

ReinvestRate = [0.03; 0.035; 0.04; 0.045; 0.05];
[BondEquiv, EffectiveRate] = bndtotalreturn(Price, CouponRate, ...
Settle, Maturity, ReinvestRate, 'HorizonDate', HorizonDate)
BondEquiv = 

    0.0557
    0.0538
    0.0521
    0.0505
    0.0490

EffectiveRate = 

    0.0565
    0.0546
    0.0528
    0.0511
    0.0496

Use bndtotalreturn with datetime inputs to compute the total return for a fixed-coupon bond, given an investment horizon date.

Price = 101;
CouponRate = 0.05;
Settle = datetime('15-Nov-2011','Locale','en_US');
Maturity = datetime('15-Nov-2031','Locale','en_US');
HorizonDate = datetime('15-Nov-2021','Locale','en_US');
ReinvestRate = 0.04;
[BondEquiv, EffectiveRate] = bndtotalreturn(Price, CouponRate, ...
Settle, Maturity, ReinvestRate, 'HorizonDate', HorizonDate)
BondEquiv = 0.0521
EffectiveRate = 0.0528

Input Arguments

collapse all

Clean price at the settlement date, specified as a scalar or a NINST-by-1 vector.

Data Types: double

Coupon rate, specified as a scalar or a NINST-by-1 vector of decimal values.

Data Types: double

Settlement date of the fixed-coupon bond, specified as scalar or a NINST-by-1 vector of serial date numbers, date character vectors, or datetime arrays. If supplied as a NINST-by-1 vector of dates, settlement dates can be different, as long as they are before the Maturity date and HorizonDate.

Data Types: double | char | datetime

Maturity date of the fixed-coupon bond, specified as scalar or a NINST-by-1 vector of serial date numbers, date character vectors, or datetime arrays.

Data Types: double | char | datetime

Reinvestment rate (the rate earned by reinvesting the coupons), specified as scalar or a NINST-by-2 vector of decimal values.

Data Types: double

Name-Value Pair Arguments

Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside single quotes (' '). You can specify several name and value pair arguments in any order as Name1,Value1,...,NameN,ValueN.

Example: [BondEquiv,EffectiveRate] = bndtotalreturn(Price,CouponRate,Settle,Maturity,ReinvestRate,'HorizonDate','15-Nov-2021')

collapse all

Investment horizon date, specified as a scalar or a NINST-by-1 vector using serial date numbers, date character vectors, or datetime arrays.

If HorizonDate is unspecified, the total return is calculated to Maturity.

Data Types: double | char | datetime

Price at investment horizon date, specified as a scalar or a NINST-by-1 vector.

If HorizonPrice is unspecified, the price at the HorizonDate is calculated based on the ReinvestRate. If the HorizonDate equals the Maturity date, the HorizonPrice is ignored and the total return to maturity is calculated based on the Face value.

Data Types: double

Number of coupon payments per year, specified as scalar or a NINST-by-1 vector using the values: 0, 1, 2, 3, 4, 6, or 12.

Data Types: double

Day-count basis, specified as a scalar or a NINST-by-1 vector. Values are:

  • 0 = actual/actual

  • 1 = 30/360 (SIA)

  • 2 = actual/360

  • 3 = actual/365

  • 4 = 30/360 (PSA)

  • 5 = 30/360 (ISDA)

  • 6 = 30/360 (European)

  • 7 = actual/365 (Japanese)

  • 8 = actual/actual (ICMA)

  • 9 = actual/360 (ICMA)

  • 10 = actual/365 (ICMA)

  • 11 = 30/360E (ICMA)

  • 12 = actual/365 (ISDA)

  • 13 = BUS/252

For more information, see basis.

Data Types: double

End-of-month rule flag, specified as a scalar or a NINST-by-1 vector. This rule applies only when Maturity is an end-of-month date for a month having 30 or fewer days.

  • 0 = Ignore rule, meaning that a bond coupon payment date is always the same numerical day of the month.

  • 1 = Set rule on, meaning that a bond coupon payment date is always the last actual day of the month.

Data Types: logical

Bond Issue date, specified as a scalar or a NINST-by-1 vector using serial date numbers, date character vectors, or datetime arrays.

If you do not specify an IssueDate, the cash flow payment dates are determined from other inputs.

Data Types: double | char | datetime

Irregular or normal first coupon date, specified as a scalar or a NINST-by-1 vector using serial date numbers, date character vectors, or datetime arrays.

If you do not specify a FirstCouponDate, the cash flow payment dates are determined from other inputs.

Data Types: double | char | datetime

Irregular or normal last coupon date, specified as a scalar or a NINST-by-1 vector using serial date numbers, date character vectors, or datetime arrays.

If you do not specify a LastCouponDate, the cash flow payment dates are determined from other inputs.

Data Types: double | char | datetime

Forward starting date of payments, specified as a scalar or a NINST-by-1 vector using serial date numbers, date character vectors, or datetime arrays.

If you do not specify a StartDate, the effective start date is the Settle date.

Data Types: double | char | datetime

Face value of the bond, specified as a scalar or a NINST-by-1 vector.

Data Types: double

Compounding frequency for yield calculation, specified as a scalar or a NINST-by-1 vector.

  • 1 — Annual compounding

  • 2 — Semiannual compounding

  • 3 — Compounding three times per year

  • 4 — Quarterly compounding

  • 6 — Bimonthly compounding

  • 12 — Monthly compounding

Note

By default, SIA bases (0-7) and BUS/252 use a semiannual compounding convention and ICMA bases (8-12) use an annual compounding convention.

Data Types: double

Basis used to compute the discount factors for computing the yield, specified as a scalar or a NINST-by-1 vector. Values are:

  • 0 = actual/actual

  • 1 = 30/360 (SIA)

  • 2 = actual/360

  • 3 = actual/365

  • 4 = 30/360 (PSA)

  • 5 = 30/360 (ISDA)

  • 6 = 30/360 (European)

  • 7 = actual/365 (Japanese)

  • 8 = actual/actual (ICMA)

  • 9 = actual/360 (ICMA)

  • 10 = actual/365 (ICMA)

  • 11 = 30/360E (ICMA)

  • 12 = actual/365 (ISDA)

  • 13 = BUS/252

For more information, see basis.

Note

The default behavior is for SIA bases (0-7) to use the actual/actual day count to compute discount factors, and for ICMA day counts (812) and BUS/252 to use the specified DiscountBasis.
