Finance[DirtyPrice] - calculate the dirty price of a bond
Calling Sequence
DirtyPrice(bond, yield, compounding, opts)
Parameters
bond
-
fixed- or floating-rate bond data structure; bond
yield
non-negative constant; desired yield
compounding
Simple, Continuous, Compounded, or SimpleThenCompounded; the underlying compounding type
opts
equations of the form option = value where option is evaluationdate; specify options for the DirtyPrice command
Description
The DirtyPrice command computes the dirty price of a bond, given its yield. Dirty price does include any accrued interest that has accumulated since the last coupon payment. The dirty price of a bond is the same as the net present value of a bond (see NetPresentValue). See the CleanPrice command to calculate the clean price of a bond, which does not include any accrued interest.
The parameter bond is either a fixed coupon bond or floating rate bond. The parameter yield is the desired yield.
Options
evaluationdate = a string containing a date specification in a format recognized by ParseDate or a date data structure -- This option specifies the evaluation date. By default this is set to the global evaluation date (see EvaluationDate).
Compatibility
The Finance[DirtyPrice] command was introduced in Maple 15.
For more information on Maple 15 changes, see Updates in Maple 15.
Examples
Consider a zero-coupon bond with face value 100 maturing in one year.
For bonds the DirtyPrice is equivalent to the NetPresentValue command when the discount rate is constant and equal to the yield. Similarly, the InternalRateOfReturn command is equivalent to the YieldFromDirtyPrice command.
Consider a 3-year bond with face value of 100 that pays a fixed coupon of 3 percent issued on March 15, 2005.
Reset the default day counter to be Thirty360European.
Calculate the purchase price of the bond using five different methods. Note that by default all rates are assumed to be based on continuous compounding.
Here is the same bond using a different business day convention and day counter.
Note that the NetPresentValue command will adjust the evaluation date according to the underlying business day convention.
