Crr presentation from naojan
Notes: CRR presentation.pptx, CRRBOPMv2.xlsx
Jarrow-Rudd Tree (JR) tree is assumes 50% probability in the u and d. CRR don't.
Slide 6
Step 1. Binomial model acts
similarly to the asset that exists in a risk neutral world.
pu+qd=ei∗Δt=r
where
Δt=tnt=term of the optionn=number of periods
Its variance:
pu2+qd2–e(i∗Δt)2=σ2Δt
Slide 9 - Notice
that the lattice is symmetrical, that is due to the assumption that
d=1/u (ud=1). Thus , it is easier to program since it involves fewer steps.
