Available in PDF, EPUB and Kindle. Book excerpt: The market's risk neutral probability distribution for the value of an asset on a future date can be extracted from the prices of a set of options that mature on that date, but two key technical problems arise. In order to obtain a full well-behaved density, the option market prices must be smoothed and interpolated, and some way must be found to complete the tails beyond the range spanned by the available options. This paper develops an approach that solves both problems, with a combination of smoothing techniques from the literature modified to take account of the market's bid-ask spread, and a new method of completing the density with tails drawn from a Generalized Extreme Value distribution. We extract twelve years of daily risk neutral densities from Samp;P 500 index options and find that they are quite different from the lognormal densities assumed in the Black-Scholes framework, and that their shapes change in a regular way as the underlying index moves. Our approach is quite general and has the potential to reveal valuable insights about how information and risk preferences are incorporated into prices in many financial markets.

Available in PDF, EPUB and Kindle. Book excerpt: Diese Studie schätzt implizite Risiko neutrale Dichtefunktionen (RND) von täglich beobachtbaren Marktpreisen von Optionen auf den DAX30 Aktienindex und von Aktienoptionen auf die neun grössten DAX Werte. Über einen Untersuchungszeitrum von Januar 2001 bis Dezember 2004 werden die impliziten Dichtefunktionen durch eine Mischung von zwei Lognormalverteilungen approximiert. Verschiedene Masse zur Messung der Streuung, Asymmetrie und der Wahrscheinlichkeit extremer Ereignisse werden zwischen den einzelnen Basiswerten verglichen. Die impliziten Dichtefunktionen für den Index als auch für die verschiedenen Aktien sind konsistent linksschief und leptokurtisch. Die RND des Marktes hat dabei eine negativere Schiefe und eine höhere Kurtosis als alle impliziten Verteilungen der Komponenten. Diese Struktur ist im weiteren Sinne konsistent mit der Annahme, dass sich die individuellen Aktienerträge gemäss einem Single Index Modell entwickeln.

Download or read book A Class of Risk Neutral Densities with Heavy Tails written by Niels Vaever Hartvig and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: From observed bid and ask prices of European call and put options we estimate the risk neutral density of a stock at some future time t gt; 0. We restrict attention to a class of densities with heavy tails and use a Bayesian formulation in order to study the variation in the distributions fitting the data. Heavy tails are here meant in the intuitive sense of being heavier than the tails of a normal distribution. From the fitted risk neutral density we also consider the inverse problem of finding the volatility in a diffusion model for the price process. Finally, we apply our methods to data on the Samp;P 500 index.

Book excerpt: In this study we compare the quality and information content of risk neutral densities obtained by various methods. We consider a non-parametric method based on a mixture of log-normal densities, the semi-parametric ones based on an Hermite approximation of Madan and Milne, or based on an Edgeworth expansion of Jarrow and Rudd, the parametric approach of Malz which assumes a jump-diffusion for the underlying process, and eventually Heston's approach assuming a stochastic volatility model. We apply those models on FRF/DEM exchange rate options for two dates, for various maturities. Models differ when important news hit the market (here the 1997 snap elections). The non-parametric model provides a good fit to options prices but is unable under critical circumstances to provide as much information about market participants expectations than Malz's jump-diffusion model.

This book was released on 2012-08-01 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Little progress has been made so far in addressing—in a comprehensive way—the externalities caused by impact of the interconnectedness within institutions and markets on funding and market liquidity risk within financial systems. The Systemic Risk-adjusted Liquidity (SRL) model combines option pricing with market information and balance sheet data to generate a probabilistic measure of the frequency and severity of multiple entities experiencing a joint liquidity event. It links a firm’s maturity mismatch between assets and liabilities impacting the stability of its funding with those characteristics of other firms, subject to individual changes in risk profiles and common changes in market conditions. This approach can then be used (i) to quantify an individual institution’s time-varying contribution to system-wide liquidity shortfalls and (ii) to price liquidity risk within a macroprudential framework that, if used to motivate a capital charge or insurance premia, provides incentives for liquidity managers to internalize the systemic risk of their decisions. The model can also accommodate a stress testing approach for institution-specific and/or general funding shocks that generate estimates of systemic liquidity risk (and associated charges) under adverse scenarios.

Download or read book Financial Density Forecasts a Comprehensive Comparison of Risk neutral and Historical Schemes written by Ricardo Crisóstomo and published by . This book was released on 2017 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: We investigate the forecasting ability of the most commonly used benchmarks in financial economics. We approach the main methodological caveats of probabilistic forecasts studies -small samples, limited models and non-holistic validations- by performing a comprehensive comparison of 15 predictive schemes during a time period of over 21 years. All densities are evaluated in terms of their statistical consistency, local accuracy and forecasting errors. Through the development of a new indicator, the Integrated forecast Score (IFS), we show that risk-neutral densities outperform historical-based predictions in terms of information content. We find that the Variance Gamma model generates the highest out-of-sample likelihood of observed prices and the lowest predictive errors, whereas the ARCH-based GRJ-FHS delivers the most consistent forecasts across the entire density range. In contrast, lognormal densities, the geston model or the non-parametric Breeden-Litzenberger formula yield biased predictions and are rejected in statistical tests.

Download or read book Recovering Risk Neutral Densities written by Oleg Bondarenko and published by . This book was released on 2008 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper proposes a novel nonparametric method to recover the implied risk-neutral density (RND) from option prices. The main advantages of this method are that it 1) is almost completely agnostic about the true underlying process, 2) controls against overfitting while allowing for small samples, 3) always results in sensible arbitrage-free distributions, 4) estimates the RND over the observable range of strikes only, without involving any extrapolation of density in the tails, 5) is computationally very simple, and 6) can be used to estimate multivariate RNDs. In an empirical application, the new method is implemented on the Samp;P Index options data over the period from 1991 to 1995. To characterize shapes of the Index's RNDs the paper uses the percentile moments which overcome unobservability of the tails of a distribution. The implied RNDs exhibit persistent negative skewness and excessive peakedness. The departures from lognormality become more pronounced as option maturity increases. Day-to-day variation of the RNDs is found to be related to the recent performance of the Index. In particular, on trading days when the Index declines the implied RNDs are more skewed and peaked than when the Index advances. Finally, the implied probabilities of extreme outcomes are also estimated.

Available in PDF, EPUB and Kindle. Book excerpt: In this paper we expand the literature of risk neutral density estimation across maturities from implied volatility curves, usually estimated and interpolated through cubic smoothing splines. The risk neutral densities are computed through the second derivative as in Panigirtzoglou and Skiadopoulos (2004), which we extend through a Bayesian approach to the problem, featuring: (1) an extension to a multivariate setting across maturities and over time; (2) a flexible estimation approach for the smoothing parameter, traditionally assumed common to all assets, known and fixed across maturities and time, but now potentially different between assets and maturities, and over time; and (3) information borrowing about the implied curves and risk neutral densities not only across different option maturities, but also dynamically.

Download or read book The Equity Premium and The Volatility Spread written by Bruno Feunou and published by . This book was released on 2016 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: We introduce the Homoscedastic Gamma [HG] model where the distribution of returns is characterized by its mean, variance and an independent skewness parameter under both measures. The model predicts that the spread between historical and risk-neutral volatilities is a function of the risk premium and of skewness. In fact, the equity premium is twice the ratio of the volatility spread to skewness. We measure skewness from option prices and test these predictions. We find that conditioning on skewness increases the predictive power of the volatility spread and that coefficient estimates accord with theory. In short, the data do not reject the model's implications for the equity premium. We also check the model's implications for option pricing and show that the information content of skewness leads to improved in-sample and out-of-sample pricing performances as well as improved hedging performances. Our results imply that expanding around the Gaussian density is restrictive and does not offer sufficient flexibility to match the skewness and kurtosis implicit in option data. Finally, we document the term structure of option-implied volatility, skewness and kurtosis and find that time-dependence in returns has a greater impact on skewness.

Book excerpt: An overview of methods used for estimation of option-implied risk-neutral probability density functions (PDFs) is presented in the study, and one of such methods, double lognormal approach, is used for the analysis of the information content of the EUR/PLN currency options on the Polish market. Estimated PDFs have proven to provide superior information concerning future volatility than historical volatility, yet their forecasting power is comparable to that of the Black-Scholes model. There are no strong grounds for using PDFs as a predictor of the future EUR/PLN exchange rate. Low informative content does not directly follow, as PDFs can be used as an indicator of markets conditions. The issues that could be addressed more thoroughly in the future studies concern the assumption of risk neutrality and the impact of the estimation method on the higher moments of the distribution.
