The JumpDiffusion function calculates the theoretical price, sensitivities, and the implied volatility of options using the Jump-Diffusion model. See Vanilla Option Models for a further explanation.

Note: Optional arguments are shown in Italics. MarketPrice is not Optional for the Implied Volatility Calculation.
Individual Models within the Jump-Diffusion Model are as follow:
Black Model |
InterestRate = YieldRate |
Black-Scholes Model |
YieldRate = 0 |
Garman-Kohlhagen Model |
YieldRate = Foreign Interest Rate |
Argument |
Description |
OptionType |
Alphanumeric value indicating the type of option: •Call = 1 or "c" (case insensitive) •Put = 2 or "p" (case insensitive) •Straddle = 3 or "s" (case insensitive) |
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 •IntrinsicValue = 10 •StrikeSensitivity = 11 •TimeValue = 12 •Implied Strike = 13 |
AssetPrice |
The price of the underlying asset. Must be > 0. |
StrikePrice |
The price at which the asset can be purchased if the option is a call or sold if the option is a put. Must be > 0. |
TimeExpire |
Time expressed in either Days or Years (depending on the TimeFormat value) until the options expiration. Must be > 0. |
Volatility |
Annualized volatility of the underlying security. Must be > 0. |
JumpsPerYear |
The expected number of jumps per year. |
PercentTotalVol |
The annual price volatility of the underlying security. |
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. For futures contracts, the Yield Rate is the same as the Interest Rate. This rate is interpreted as a continuously compounded rate unless specified otherwise in the YieldType argument. |
Dividends* |
A two-dimensional array or range of Dividend Dates and Amount pairs where the first column is the date and the second is the amount. The Dividend Dates are a range (array) of ascending unique values. All dividend dates and amounts must both be > 0.
As an example: Dividends Date Amount 0.0 0.20 0.5 0.15 1.0 0.30 1.5 0.25 2.0 0.15 2.5 0.40
*Used for the DivArr (Dividend Array) based model only |
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, TimeExDiv, DivFrequency). If omitted, Days are used as the default. Specified as either: •Days = 0 or "D" (case insensitive) •Years = 1 or "Y" (case insensitive) |
DivAmount |
Optional. The amount of the dividend(s). If omitted, an amount of 0 is used. Amount must be > 0. |
TimeExDiv |
Optional. The time in Days or Years until the first dividend is received. If omitted, a value of 0 is used and therefore no dividends are assessed. Value must be > 0 for dividends to be considered. |
DivFrequency |
Optional. The time in Days or Years between dividend payments. If omitted, a value of 0 is used and therefore the only dividend assessed occurs at the TimeExDiv time. The value must be > 0 for multiple dividends to be considered. |
DividendStyle |
Optional. Numeric value indicating the Style or method that dividends are handled. If omitted, the discrete cash method is used (i.e. DividendStyle = 0). •Discrete cash flow method = 0 •Continuous yield method = 1 |
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 the functions for a European call option whose asset price 60 days from expiration of an option is $35.75, the exercise price of the option is $30, the risk-free interest rate is 6% per annum, the yield rate is 07% per annum, the annual volatility is 30%, the annual price volatility of the underlying security is 40%, and the expected number of jumps per year is 3. This means that the AssetPrice = $35.75, StrikePrice = $30, InterestRate = 6%, YieldRate = 0%, TimeExpire = 60 days, Volatility = 30%, PercentTotalVol = 40%, and JumpsPerYear = 3. There are no dividends and all interest rates are considered continuous. So, |
