Calculates Option Prices by Merton's 1976 Jump Diffusion Model by Closed Form Matrixwise Calculation for Full Surface
cp [1,-1] Call,Put
S Current Price
K Strike Vector
T Time-to-Maturity Vector
sigma Volatility of Diffusion
q Div Yield
lambda Poisson Rate
a Jump Mean
b Jump Std Deviation
n Event Count (Limited to 170 since factorial(170)=7.26e306)
S = 100; K = (20:5:180)'; T = (0.1:0.1:5)';
sigma = 0.2; r = 0.0075; q = 0; lambda = 0.01; a = -0.2; b = 0.6; n = 50;
P = ia_calcMJDOptionPrice(cp,S,K,T,sigma,r,q,lambda,a,b,n);
[mK,mT] = meshgrid(K,T); [sigma,C] = calcBSImpVol(cp,P,S,mK,mT,r,q);
subplot(2,1,1); mesh(mK,mT,P); subplot(2,1,2); mesh(mK,mT,sigma);
Merton, 1976, Option Pricing When Underlying Stock Returns are Discontinuous
run very good, the value matches to original BS model! Thanks.
Do you have matrixwise Black Scholes Option price?
Excellent program, well written and knowledgable author. Was kind enough to answer my questions and showed me how to execute the program to fit my needs. Very professional and kind.
Fixed small bug in the example given which omitted defining the variable "cp", and called "ia_calcMJDOptionPrice" instead of "calcMJDOptionPrice"
