This book was released on 2017 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk neutral densities recovered from option prices can be used to infer market participantsņ expectations of future stock returns and are a vital tool for pricing illiquid exotic options. Although there is a broad literature on the subject, most studies do not address the likelihood of default. To fill this gap, in this paper we develop a novel method to retrieve the risk neutral probability density function from call options written on a defaultable asset. The primary advantage of the method is that default probabilities inferred by the model can be analytically expressed and, if available, can be incorporated as an input in a ፟lexible, robust and easily implementable manner.

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.
Book Synopsis A Simple and Reliable Way to Compute Option-Based Risk-Neutral Distributions by : Allan M. Malz
Download or read book A Simple and Reliable Way to Compute Option-Based Risk-Neutral Distributions written by Allan M. Malz and published by . This book was released on 2014 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes a method for computing risk-neutral density functions based on the option-implied volatility smile. Its aim is to reduce complexity and provide cookbook-style guidance through the estimation process. The technique is robust and avoids violations of option no-arbitrage restrictions that can lead to negative probabilities and other implausible results. I give examples for equities, foreign exchange, and long-term interest rates.

Book Synopsis Improved Lower Bounds of Call Options Written on Defaultable Assets by : Greg Orosi
Download or read book Improved Lower Bounds of Call Options Written on Defaultable Assets written by Greg Orosi and published by . This book was released on 2015 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper provides an improved model-independent lower bound of European call options written on defaultable assets. Based on static arbitrage arguments, improved lower bounds are established, which also depend on the probability of option implied default. The results are also extended to dividend paying stocks. Moreover, our findings imply that it is never optimal to exercise certain American call options. Finally, we discuss the implications of our results for constructing an arbitrage-free volatility surface and extracting risk-neutral densities from option prices.

Book Synopsis Recovering Risk-Neutral Densities by : Oleg Bondarenko
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.
Book Synopsis Are We Extracting the True Risk Neutral Density from Option Prices? A Question with No Easy Answer by : James Huang
Download or read book Are We Extracting the True Risk Neutral Density from Option Prices? A Question with No Easy Answer written by James Huang and published by . This book was released on 2009 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper we raise a question on the theoretical foundation of option implied risk neutral density. We prove that given any number of options, there exist numerous risk neutral densities which are piecewise constant, have only two values, either an lower bound or an upper bound on the true risk neutral density, and price all these options correctly. We also prove that given any number of options, there exist numerous risk neutral densities consistent with the prices of all these options whose first derivatives are piecewise constant and have only two values, either an lower bound or an upper bound on the true risk neutral density's first derivative. Similar results are proved with respect to the true risk neutral density's higher order derivatives. These results show how large errors we can make when extracting RNDs from option prices.

Book Synopsis Retrieving Risk Neutral Moments and Expected Quadratic Variation from Option Prices by : Leonidas Rompolis
Download or read book Retrieving Risk Neutral Moments and Expected Quadratic Variation from Option Prices written by Leonidas Rompolis and published by . This book was released on 2017 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper derives exact formulas for retrieving risk neutral moments of future payoffs of any order from generic European-style option prices. It also provides an exact formula for retrieving the expected quadratic variation of the stock market implied by European option prices, which nowadays is used as an estimate of the implied volatility, and a formula approximating the jump component of this measure of variation. To implement the above formulas to discrete sets of option prices, the paper suggests a numerical procedure and provides upper bounds of its approximation errors. The performance of this procedure is evaluated through a simulation and an empirical exercise. Both of these exercises clearly indicate that the suggested numerical procedure can provide accurate estimates of the risk neutral moments, over different horizons ahead. These can be in turn employed to obtain accurate estimates of risk neutral densities and calculate option prices, efficiently, in a model-free manner. The paper also shows that, in contrast to the prevailing view, ignoring the jump component of the underlying asset can lead to seriously biased estimates of the new volatility index suggested by the Chicago Board Options Exchange (CBOE).

Book Synopsis Estimating Option-Implied Distributions in Illiquid Markets and Implementing the Ross Recovery Theorem by : Emlyn James Flint
Download or read book Estimating Option-Implied Distributions in Illiquid Markets and Implementing the Ross Recovery Theorem written by Emlyn James Flint and published by . This book was released on 2016 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: We describe how forward-looking information on the statistical properties of an asset can be extracted directly from options market data and how this can be used practically in portfolio management. Although the extraction of a forward-looking risk-neutral distribution is well-established in the literature, the issue of estimation in an illiquid market is not. We use the deterministic SVI volatility model to estimate weekly risk-neutral distribution surfaces. The issue of calibration with sparse and noisy data is considered at length and a simple but robust fitting algorithm is proposed. Furthermore, we attempt to extract real-world implied information by implementing the recovery theorem introduced by Ross (2015). Recovery is an ill-posed problem that requires careful consideration. We describe a regularization methodology for extracting real-world implied distributions and implement this method on a history of SVI volatility surfaces. We analyse the first four moments from the implied risk-neutral and real-world implied distributions and use them as signals within a simple tactical asset allocation framework, finding promising results.

Available in PDF, EPUB and Kindle. Book excerpt: In this paper we present a new method of approximating the risk neutral density (RND) from option prices based on the C-type Gram-Charlier series expansion (GCSE) of a probability density function. The exponential form of this type of GCSE guarantees that it will always give positive values of the risk neutral probabilities and it can allow for stronger deviations from normality, which are two drawbacks of the A-type GCSE used in practice. To evaluate the performance of the suggested expansion of the RND, the paper presents simulation and empirical evidence.
