Implied risk-neutral probability density functions from option prices: theory and application
Contents
Abstract
1 Introduction
2 The relationship between option prices and RND functions
2.1 Pricing elementary claims from option prices
2.2 The Black-Scholes (1973) formula and its RND function
2.3 The implied volatility smile curve
3 Some techniques for estimating implied terminal RND functions
3.1 A simple approach: risk-neutral histograms
3.2 Interpolating the call option pricing function directly
3.3 Interpolating the implied volatility smile curve
3.4 Fitting an assumed option pricing model to observed
option prices
3.5 Fitting an assumed parametric form for the implied RND
function to observed option prices
3.6 Application of the two-lognormal mixture approach to
equity, interest rate and foreign exchange markets
a) LIFFE equity index options
b) LIFFE options on short interest rate and long bond futures
c) Philadelphia Stock Exchange (PHLX) currency options
