Barjero pasirinkimo sandorių įkainojimo metodų tyrimas / The investigation of the barrier options pricing models

Palivonaitė, Rita 11 August 2008 (has links)
Darbe nagrinėjami barjero pasirinkimo sandorių įkainojimo metodai. Barjero pasirinkimo sandorių išmokos sutampa su įprastinių pasirinkimo sandorių išmokomis, jei išpildoma papildoma barjero sąlyga, kurią reikia įvertinti. Įkainojimui naudojami diskretieji modeliai: binominis ir trinominis, tiriama jų konvergavimas į klasikinę Black-Scholes formulę. Dėl modelio diskretumo ir barjero sąlygos konvergavimas tam tikrais atvejais yra lėtas ir nemonotoniškas. Todėl siūloma pritaikyti adaptyviojo tinklelio algoritmą, smulkinant trinominio medžio tinklelį kritinėse srityse. Šiame darbe pateikiami rezultatai, gauti palyginus barjero pasirinkimo sandorio įkainojimo modelius. / In this paper we consider barrier options pricing models. Barrier options are standard call or put options except that they disappear or appear if the asset price crosses a predeterminant set of fixing dates. Barrier options are priced using continuous state Black-Scholes model and numerical approximation techniques, such as binomial and trinomial. Because of the the barrier condition and discreteness of these models the convergence to Black-Scholes model sometimes is slow. It is offered to apply adaptive mesh model grafting small sections of fine high-resolution lattice onto a tree in trinomial model. In this work we present the comparison of the models with some numerical results for barrier options.
