چکیده

Options are believed to contain unique information on the risk-neutral moment generating function (MGF) or the risk-neutral probability density function (PDF) of the underlying asset. This paper applies the wavelet method to approximate the implied risk-neutral MGF from option prices. Monte Carlo simulations are carried out to show how the risk-neutral MGF can be obtained using the wavelet method. With the Black-Scholes model as the benchmark, we offer a novel method to reveal the implied MGF, and to price in-sample options and forecast out-of-sample option prices with the estimated MGF.

How Useful are Implied Distributions? Evidence from Stock-Index Options

SPRING 2000 THE JOURNAL OF DERIVATIVES 1 Option prices can reveal implied (risk-neutral) distributions, but it is not clear whether these are useful for forecasting or hedging or for revealing the current sentiment of investors. The authors estimate the implied distribution for stock index options in London as a mixture of two lognormals over the period 1987-1997 and find that this method is mu...

Estimating option implied risk-neutral densities using spline and hypergeometric functions

We examine the ability of two recent methods – the smoothed implied volatility smile method (SML) and the density functionals based on confluent hypergeometric functions (DFCH) – for estimating implied risk-neutral densities (RNDs) from European-style options. Two complementary Monte Carlo experiments are conducted and the performance of the two RND estimators is evaluated by the root mean inte...

1 - How useful are implied distributions? Evidence from stock-index options - Dec 1999

Option prices can be used to construct implied (risk-neutral) distributions, but it remains to be proven whether these are useful either in relation to forecasting subsequent market movements or in revealing investor sentiment. We estimate the implied distribution as a mixture of two lognormals and then test its one-day-ahead forecasting performance, using 1987-97 data on LIFFE’s FTSE-100 index...

Testing Techniques for Estimating Implied Rnds from the Prices of European-style Options

This paper examines two approaches to estimating implied risk-neutral probability density functions from the prices of European-style options. It sets up a monte carlo test to evaluate alternative techniques’ ability to recover simulated distributions based on Heston’s (1993) stochastic volatility model. The paper tests both for the accuracy and stability of the estimated summary statistics fro...

Implied Volatility Smirk

This paper studies implied volatility smirk quantitatively. We first propose a new concept of smirkness, which is defined as a triplet of at-the-money implied volatility, skewness (slope at the money) and smileness (curvature at the money) of implied volatility – moneyness curve. The moneyness is the logarithm of the strike price over the forward price, normalized by the standard deviation of e...
