Vanilla instrument object

Description

Create and price a Vanilla instrument object using this workflow:

1. Use fininstrument to create a Vanilla instrument object.

2. Use finmodel to specify a BlackScholes, Bachelier, Heston, Bates, Merton, or Dupire model for the Vanilla instrument.

3. • When using a BlackScholes model, use finpricer to specify a FiniteDifference, BlackScholes, BjerksundStensland, RollGeskeWhaley, VannaVolga, AssetTree, or AssetMonteCarlo pricing method for the Vanilla instrument.

   • When using a Heston, Bates, or Merton model, use finpricer to specify a FiniteDifference, NumericalIntegration, FFT, or AssetMonteCarlo pricing method for the Vanilla instrument.

   • When using a Dupire model, use finpricer to specify a FiniteDifference pricing method for the Vanilla instrument.

   • When using a Bachelier model, use finpricer to specify an AssetMonteCarlo pricing method for the Vanilla instrument.

For more information on this workflow, see Get Started with Workflows Using Object-Based Framework for Pricing Financial Instruments.

For more information on the available models and pricing methods for a Vanilla instrument, see Choose Instruments, Models, and Pricers.

Creation

Syntax

VanillaObj = fininstrument(InstrumentType,'Strike',strike_value,'ExerciseDate',exercise_date)

VanillaObj = fininstrument(___,Name,Value)

Description

VanillaObj = fininstrument(InstrumentType,'Strike',strike_value,'ExerciseDate',exercise_date) creates a Vanilla object by specifying InstrumentType and sets the properties for the required name-value pair arguments Strike and ExerciseDate. For more information on a Vanilla instrument, see More About.

VanillaObj = fininstrument(___,Name,Value) sets optional properties using additional name-value pairs in addition to the required arguments in the previous syntax. For example, VanillaObj = fininstrument("Vanilla",'Strike',100,'ExerciseDate',datetime(2019,1,30),'OptionType',"put",'ExerciseStyle',"American",'Name',"vanilla_instrument") creates a Vanilla put option with an American exercise. You can specify multiple name-value pair arguments.

Input Arguments

InstrumentType — Instrument type

string with value "Vanilla" | character vector with value 'Vanilla'

Instrument type, specified as a string with the value of "Vanilla" or a character vector with the value of 'Vanilla'.

Data Types: char | string

Vanilla Name-Value Pair Arguments

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

Example: VanillaObj = fininstrument("Vanilla",'Strike',100,'ExerciseDate',datetime(2019,1,30),'OptionType',"put",'ExerciseStyle',"American",'Name',"vanilla_instrument")

Required Vanilla Name-Value Pair Arguments

'Strike' — Option strike price value

nonnegative numeric | vector

Option strike price value, specified as the comma-separated pair consisting of 'Strike' and a scalar nonnegative numeric value.

Note

When using a "Bermudan" ExerciseStyle with a FiniteDifference pricer, the Strike is a vector.

Data Types: double

'ExerciseDate' — Option exercise date

datetime | serial date number | date character vector | date string | vector when ExerciseStyle is "Bermudan"

Option exercise date, specified as the comma-separated pair consisting of 'ExerciseDate' and a scalar datetime, serial date number, date character vector, or date string.

Note

For a European option, there is only one ExerciseDate on the option expiry date.

When using a "Bermudan" ExerciseStyle with a FiniteDifference pricer, the ExerciseDate is a vector.

If you use a date character vector or date string, the format must be recognizable by datetime because the ExerciseDate property is stored as a datetime.

Data Types: double | char | string | datetime

Optional Vanilla Name-Value Pair Arguments

'OptionType' — Option type

"call" (default) | string with value "call" or "put" | character vector with value 'call' or 'put'

Option type, specified as the comma-separated pair consisting of 'OptionType' and a scalar string or character vector.

Note

When you use a RollGeskeWhaley pricer with a Vanilla option, OptionType must be 'call'.

Data Types: char | string

'ExerciseStyle' — Option exercise style

"European" (default) | string with value "European", "American", or "Bermudan" | character vector with value 'European', 'American', or 'Bermudan'

Option exercise style, specified as the comma-separated pair consisting of 'ExerciseStyle' and a scalar string or character vector.

Note

• When you use a BlackScholes pricer with a Vanilla option, the 'American' option type is not supported.

• When you use a RollGeskeWhaley or a BjerksundStensland pricer with a Vanilla option, you must specify an 'American' option.

• When you use a NumericalIntegration pricer with a Bates, Merton, or Heston model for a Vanilla option, the ExerciseStyle must be 'European'.

• When you use a FFT pricer with a Bates, Merton, or Heston model for a Vanilla option, the ExerciseStyle must be 'European'.

• When you use an AssetMonteCarlo pricer with a BlackScholes, Bates, Merton, or Heston model for a Vanilla option, the ExerciseStyle can be 'American', 'European', or 'Bermudan'.

• When you use a FiniteDifference pricer with a BlackScholes, Bachelier, Dupire, Bates, Merton, or Heston model for a Vanilla option, the ExerciseStyle can be 'American', 'European', or 'Bermudan'.

For more information on ExerciseStyle, see Supported Exercise Styles.

Data Types: string | char

'Name' — User-defined name for instrument

" " (default) | string | character vector

User-defined name for the instrument, specified as the comma-separated pair consisting of 'Name' and a scalar string or character vector.

More About

Vanilla Option

A vanilla option is a category of options that includes only the most standard components.

A vanilla option has an expiration date and straightforward strike price. American-style options and European-style options are both categorized as vanilla options.

The payoff for a vanilla option is as follows:

• For a call: $$\max (St-K,0)$$

• For a put: $$\max (K-St,0)$$

where:

St is the price of the underlying asset at time t.

K is the strike price.

For more information, see Vanilla Option.

Tips

After creating a Vanilla instrument object, you can use setExercisePolicy to change the size of the options. For example, if you have the following instrument:

VanillaOpt = fininstrument("Vanilla",'ExerciseDate',datetime(2021,5,1),'Strike',29,'OptionType',"put",'ExerciseStyle',"European")

To modify the Vanilla instrument's size by changing the ExerciseStyle from "European" to "American", use setExercisePolicy:

VanillaOpt = setExercisePolicy(VanillaOpt,[datetime(2021,1,1) datetime(2022,1,1)],100,'American')
