AsianMC: Asian option valuation with Monte Carlo (MC) simulation.

In QFRM: Pricing of Vanilla and Exotic Option Contracts

Description

Calculates the price of an Asian option using Monte Carlo simulations to determine expected payout.
Assumptions:
The option follows a General Brownian Motion (BM),
ds = mu * S * dt + sqrt(vol) * S * dW where dW ~ N(0,1).
The value of mu (the expected price increase) is o$r, the risk free rate of return (RoR).
The averaging period is the life of the option.

Usage

AsianMC(o = OptPx(o = Opt(Style = "Asian"), NSteps = 5), NPaths = 5)

Arguments

o	The OptPx Asian option to price.
NPaths	The number of simulation paths to use in calculating the price,

Value

The option o with the price in the field PxMC based on MC simulations.

Examples

(o = AsianMC())$PxMC #Price = ~5.00,  using default values

  o = OptPx(Opt(Style='Asian'), NSteps = 5)
  (o = AsianMC(o, NPaths=5))$PxMC #Price = ~$5

  (o = AsianMC(NPaths = 5))$PxMC # Price = ~$5

  o = Opt(Style='Asian', Right='Put',S0=10, K=15)
  o = OptPx(o, r=.05, vol=.1, NSteps = 5)
  (o = AsianMC(o, NPaths = 5))$PxMC # Price = ~$4

  #See J.C.Hull, OFOD'2014, 9-ed, ex.26.3, pp.610.

 o = OptPx(o,r=0.1,q=0,vol=0.4,NSteps=5)
 (o = AsianBS(o))$PxBS   #Price is 5.62.
 (o = AsianMC(o))$PxMC
