Published / Preprint: Pricing and Hedging Long-Term Options. (arXiv:1410.8160v1 [q-fin.MF])

Posted: 30 Oct 2014 05:34 PM PDT

In this article, we investigate the behavior of long-term options. In many cases, option prices follow an exponential decay (or growth) rate for further maturity dates. We determine under what conditions option prices are characterized by this property. To see this, we use the martingale extraction method through which a pricing operator is transformed into a semigroup operator, which is easier...

Published / Preprint: Efficient price dynamics in a limit order market: an utility indifference approach. (arXiv:1410.8224v1 [q-fin.PR])

Posted: 30 Oct 2014 05:34 PM PDT

We construct an utility-based dynamic asset pricing model for a limit order market. The price is nonlinear in volume and subject to market impact. We solve an optimal hedging problem under the market impact and derive the dynamics of the efficient price, that is, the asset price when a representative liquidity demander follows an optimal strategy. We show that a Pareto efficient allocation is...

Published / Preprint: Optimal Allocation of Trend Following Strategies. (arXiv:1410.8409v1 [q-fin.PM])

Posted: 30 Oct 2014 05:34 PM PDT

We consider a portfolio allocation problem for trend following (TF) strategies on multiple correlated assets. Under simplifying assumptions of a Gaussian market and linear TF strategies, we derive analytical formulas for the mean and variance of the portfolio return. We construct then the optimal portfolio that maximizes risk-adjusted return by accounting for inter-asset correlations. The dynamic...

Published / Preprint: When does the stock market listen to economic news? New evidence from copulas and news wires. (arXiv:1410.8427v1 [q-fin.EC])

Posted: 30 Oct 2014 05:34 PM PDT

We study association between macroeconomic news and stock market returns using the statistical theory of copulas, and a new comprehensive measure of news based on the indexing of news wires. We find the impact of economic news on equity returns to be nonlinear and asymmetric. In particular, controlling for economic conditions and surprises associated with releases of economic data, we find that...

Published / Preprint: The Model Confidence Set package for R. (arXiv:1410.8504v1 [stat.CO])

Posted: 30 Oct 2014 05:34 PM PDT

This paper presents the R package MCS which implements the Model Confidence Set (MCS) procedure recently developed by Hansen et al. (2011). The Hansen's procedure consists on a sequence of tests which permits to construct a set of 'superior' models, where the null hypothesis of Equal Predictive Ability (EPA) is not rejected at a certain confidence level. The EPA statistic tests is calculated for...
