The Compound function calculates the theoretical price, sensitivities, the implied volatility, and the implied strike value of a European compound option using Rubinstein’s model. See Multiple Exercise Options for a further explanation.

(OptionType, ModelStatistic, Asset, StrikeOption, StrikeUnderly, TimeOption, TimeExpire, Volatility, InterestRate, YieldRate, MarketPrice, TimeFormat, InterestType, YieldType)

Note: Optional arguments are shown in Italics. MarketPrice is not Optional for the Implied Calculations.

 

 

Argument

Description

OptionType

Alphanumeric value indicating the type of option:

Call_Call = 1 or "cc" (call option on a call option)

Call_Put = 2 or "cp" (call option on a put option)

Put_Call = 3 or "pc" (put option on a put option)

Put_Put = 4 or "pp" (put option on a put option)

ModelStatistic

Numeric value indicating the type of function required for the return value:

Theoretical = 1

Delta = 2

Gamma = 3

Theta = 4

ImpliedVol = 5

Vega = 6

Rho = 7

Psi = 8

Lambda = 9

UnderlyStrikeSensativity = 58

UnderlyImpliedStrike = 59

OptionStrikeSensativity = 60

OptionImpliedStrike = 61

Asset

The price of the underlying asset. Must be > 0.

StrikeOption

The price at which the compound option can be purchased if the option is a call or sold if the option is a put. Must be > 0.

StrikeUnderly

The price at which the underlying asset can be purchased if the option is a call or sold if the option is a put. Must be > 0.

TimeOption

The time, expressed in either Days or Years (depending on the TimeFormat value), until the expiration of the compound option.

Must be: 0 < TimeOption < TimeExpire.

TimeExpire

Time, expressed in either Days or Years (depending on the TimeFormat value), until the expiration underlying option. Must be > 0.

Volatility

Annualized volatility of the underlying security. Must be > 0.

InterestRate

Risk-free interest rate expressed as a percentage. This rate is interpreted as a continuously compounded rate unless otherwise specified in the InterestType argument.

Must be > 0.

YieldRate

Yield, expressed as a percentage (dividends or interest yield), of the underlying asset price. This rate is interpreted as a continuously compounded rate unless specified otherwise in the YieldType argument.

MarketPrice

Optional. The selling price of the option in the marketplace. This input is required when implied volatility and strike are calculated. Price must be > 0.

TimeFormat

Optional. Alphanumeric value indicating the format of the time arguments (i.e. TimeExpire). If omitted, Days are used as the default. Specified as either:

Days = 0 or "D" (case insensitive)

Years = 1 or "Y" (case insensitive)

InterestType

Optional. Alphanumeric value indicating the type of InterestRate to use when evaluating the option. This value is converted to Continuously Compounded for the calculations. If omitted, a Continuously Compounded rate is used.

YieldType

Optional. Alphanumeric value indicating the type of YieldRate to use when evaluating the option. This value is converted to Continuously Compounded for the calculations. If omitted, a Continuously Compounded rate is used.

 

 

Example

Calculate all of functions for a compound call on call option whose asset price 0.5 years from the compound option expiration date, 1 year from the underlying expiration option is $56. The exercise price of the compound call is $5, the exercise price of the underlying call is $40, the risk-free interest rate is 7% per annum, the yield rate is 4.5% per annum, and the annual volatility is 25%. All of the rates are considered continuous. So,
