Blog Post: WealthandCapitalMarketsBlog: Big Banks' exodus from Commodities

Posted: 30 May 2014 08:44 PM PDT

Goldman Sachs, Morgan Stanley, Barclays and JP Morgan used to be the biggest traders of commodity among banks. However, this space has witnessed many of the big banks exiting the business line in recent times. JPMorgan recently decided to exit physical commodities trading business by selling its raw-materials trading unit to Mercuria Energy Group Ltd. Morgan Stanley decided to sell its physical...

Published / Preprint: Mixed Tempered Stable distribution. (arXiv:1405.7603v1 [q-fin.ST])

Posted: 30 May 2014 02:31 AM PDT

In this paper we introduce a new parametric distribution, the Mixed Tempered Stable. It has the same structure of the Normal Variance Mean Mixtures but the normality assumption leaves place to a semi-heavy tailed distribution. We show that, by choosing appropriately the parameters of the distribution and under the concrete specification of the mixing random variable, it is possible to obtain some...

Published / Preprint: VAR and ES/CVAR Dependence on data cleaning and Data Models: Analysis and Resolution. (arXiv:1405.7611v1 [q-fin.RM])

Posted: 30 May 2014 02:31 AM PDT

Historical (Stressed-) Value-at-Risk ((S)VAR), and Expected Shortfall (ES), are widely used risk measures in regulatory capital and Initial Margin, i.e. funding, computations. However, whilst the definitions of VAR and ES are unambiguous, they depend on input distributions that are data-cleaning- and Data-Model-dependent. We quantify the scale of these effects from USD CDS (2004--2014), and from...

Published / Preprint: Option Pricing in a Dynamic Variance-Gamma Model. (arXiv:1405.7342v1 [q-fin.PR])

Posted: 29 May 2014 03:19 AM PDT

We present a discrete time stochastic volatility model in which the conditional distribution of the logreturns is a Variance-Gamma, that is a normal variance-mean mixture with Gamma mixing density. We assume that the Gamma mixing density is time varying and follows an affine Garch model, trying to capture persistence of volatility shocks and also higher order conditional dynamics in a...

Published / Preprint: Splitting and Matrix Exponential approach for jump-diffusion models with Inverse Normal Gaussian, Hyperbolic and Meixner jumps. (arXiv:1405.6111v2 [q-fin.CP] UPDATED)

Posted: 29 May 2014 03:19 AM PDT

This paper is a further extension of the method proposed in Itkin, 2014 as applied to another set of jump-diffusion models: Inverse Normal Gaussian, Hyperbolic and Meixner. To solve the corresponding PIDEs we accomplish few steps. First, a second-order operator splitting on financial processes (diffusion and jumps) is applied to these PIDEs. To solve the diffusion equation, we use standard...

Published / Preprint: Agency Conflicts and Cash: Estimates from a Dynamic Model

Posted: 28 May 2014 06:06 AM PDT

Which agency problems affect corporate cash policy? To answer this question, we estimate a dynamic model of finance and investment with three mechanisms that misalign managerial and shareholder incentives: limited managerial ownership of the firm, compensation based on firm size, and managerial perquisite consumption. We find that perquisite consumption critically impacts cash policy. Size-based...

Published / Preprint: The Joint Cross Section of Stocks and Options

Posted: 28 May 2014 06:06 AM PDT

Stocks with large increases in call (put) implied volatilities over the previous month tend to have high (low) future returns. Sorting stocks ranked into decile portfolios by past call implied volatilities produces spreads in average returns of approximately 1% per month, and the return differences persist up to six months. The cross section of stock returns also predicts option-implied...

Published / Preprint: Shaping Liquidity: On the Causal Effects of Voluntary Disclosure

Posted: 28 May 2014 06:06 AM PDT

Can managers influence the liquidity of their firms’ shares? We use plausibly exogenous variation in the supply of public information to show that firms actively shape their information environments by voluntarily disclosing more information than regulations mandate and that such efforts improve liquidity. Firms respond to an exogenous loss of public information by providing more timely and...

Published / Preprint: The Media and the Diffusion of Information in Financial Markets: Evidence from Newspaper Strikes

Posted: 28 May 2014 06:06 AM PDT

The media are increasingly recognized as key players in financial markets. I investigate their causal impact on trading and price formation by examining national newspaper strikes in several countries. Trading volume falls 12% on strike days. The dispersion of stock returns and their intraday volatility are reduced by 7%, while aggregate returns are unaffected. Moreover, analysis of return...

Published / Preprint: On the stationarity of Dynamic Conditional Correlation models. (arXiv:1405.6905v1 [q-fin.MF])

Posted: 28 May 2014 03:28 AM PDT

We provide conditions for the existence and the unicity of strictly stationary solutions of the usual Dynamic Conditional Correlation GARCH models (DCC-GARCH). The proof is based on Tweedie's (1988) criteria, after having rewritten DCC-GARCH models as nonlinear Markov chains. Moreover, we study the existence of their finite moments.

Published / Preprint: Transport catastrophe analysis as an alternative to a fractal description: theory and application to financial crisis time series. (arXiv:1405.6990v1 [q-fin.ST])

Posted: 28 May 2014 03:28 AM PDT

The goal of this investigation was to overcome limitations of a persistency analysis, introduced by Benoit Mandelbrot for fractal Brownian processes: nondifferentiability, Brownian nature of process and a linear memory measure. We have extended a sense of a Hurst factor by consideration of a phase diffusion power law. It was shown that pre-catastrophic stabilization as an indicator of bifurcation...

Posted: 27 May 2014 04:48 AM PDT

We investigate the role of networks of military alliances in preventing or encouraging wars between groups of countries. A country is vulnerable to attack if some allied group of countries can defeat the defending country and its (remaining) allies based on their collective military strengths. We show that there do not exist any networks which contain no vulnerable countries and that are stable...

Published / Preprint: Convergence in Multiscale Financial Models with Non-Gaussian Stochastic Volatility. (arXiv:1405.6514v1 [math.PR])

Posted: 27 May 2014 04:48 AM PDT

We consider stochastic control systems affected by a fast mean reverting volatility $Y(t)$ driven by a pure jump L\'evy process. Motivated by a large literature on financial models, we assume that $Y(t)$ evolves at a faster time scale $\frac{t}{\varepsilon}$ than the assets, and we study the asymptotics as $\varepsilon\to 0$. This is a singular perturbation problem that we...

Posted: 22 May 2014 05:38 PM PDT

We describe an exercise of using Big Data to predict the Michigan Consumer Sentiment Index, a widely used indicator of the state of confidence in the US economy. We carry out the exercise from a pure ex ante perspective. We use the methodology of algorithmic text analysis of an archive of brokers' reports over the period June 2010 through June 2013. The search is directed by...

In this paper, making use of recent statistical physics techniques and models, we address the specific role of randomness in financial markets, both at the micro and the macro level. In particular, we review some recent results obtained about the effectiveness of random strategies of investment, compared with some of the most used trading strategies for forecasting the behavior of real financial...

Posted: 22 May 2014 05:38 PM PDT

The Bivariate Dynamic Contagion Processes (BDCP) are a broad class of bivariate point processes characterized by the intensities as a general class of piecewise deterministic Markov processes. The BDCP describes a rich dynamic structure where the system is under the influence of both external and internal factors modelled by a shot-noise Cox process and a generalized Hawkes process respectively....
