cdyield

Yield on certificate of deposit (CD)

Syntax

Yield = cdyield(Price,CouponRate,Settle,Maturity,IssueDate)
Yield = cdyield(___,Basis)

Description

example

Yield = cdyield(Price,CouponRate,Settle,Maturity,IssueDate) computes the yield to maturity of a certificate of deposit given its clean price.

cdyield assumes that the certificates of deposit pay interest at maturity. Because of the simple interest treatment of these securities, this function is best used for short-term maturities (less than 1 year). The default simple interest calculation uses the Basis for the actual/360 convention (2).

Yield = cdyield(___,Basis) adds an optional argument for Basis.

This example shows how to compute the yield on the certificate of deposit (CD), given a CD with the following characteristics.

Price      = 101.125;
CouponRate = 0.05;
Settle     = '02-Jan-02';
Maturity   = '31-Mar-02';
IssueDate = '1-Oct-01';

Yield = cdyield(Price, CouponRate, Settle, Maturity, IssueDate)
Yield = 0.0039

This example shows how to use datetime inputs to compute the yield on the certificate of deposit (CD), given a CD with the following characteristics.

Price      = 101.125;
CouponRate = 0.05;
Settle     = datetime('02-Jan-02','Locale','en_US');
Maturity   = datetime('31-Mar-02','Locale','en_US');
IssueDate = datetime('1-Oct-01','Locale','en_US');

Yield = cdyield(Price, CouponRate, Settle, Maturity, IssueDate)
Yield = 0.0039

Input Arguments

collapse all

Clean price of the certificate of deposit per $100 face, specified as a numeric value using a scalar or a NCDS-by-1 or 1-by-NCDS vector.

Data Types: double

Coupon annual interest rate, specified as decimal using a scalar or a NCDS-by-1 or 1-by-NCDS vector.

Data Types: double

Settlement date of the certificate of deposit, specified as a scalar or a NCDS-by-1 or 1-by-NCDS vector using serial date numbers, date character vectors, or datetime arrays. The Settle date must be before the Maturity date.

Data Types: double | char | datetime

Maturity date of the certificate of deposit, specified as a scalar or a NCDS-by-1 or 1-by-NCDS vector using serial date numbers, date character vectors, or datetime arrays.

Data Types: double | char | datetime

Issue date for the certificate of deposit, specified as a scalar or a NCDS-by-1 or 1-by-NCDS vector using serial date numbers, date character vectors, or datetime arrays.

Data Types: double | char | datetime

(Optional) Day-count basis for the certificate of deposit, 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

Data Types: double

Output Arguments

collapse all

Simple yield to maturity of the certificate of deposit, returned as a NCDS-by-1 or 1-by-NCDS vector.
