We develop a multivariate statistical arbitrage strategy based on vine copulas - a highly flexible instrument for linear and nonlinear multivariate dependence modeling. In an empirical application on the S&P 500, we find statistically and economically significant returns of 9.25 percent p.a. and...

This paper develops a pairs trading framework based on a mean-reverting jump-diffusion model and applies it to minute-by-minute data of the S&P 500 oil companies from 1998 to 2015. The established statistical arbitrage strategy enables us to perform intraday and overnight trading. Essentially,...

Over the past 15 years,there have been a number of studies using text mining for predicting stock market data. Two recent publications employed support vector machines and second-order Factorization Machines, respectively, to this end. However, these approaches either completely neglect...

This paper develops the regime classification algorithm and applies it within a fully-edged pairs trading framework on minute-by-minute data of the S&P 500 constituents from 1998 to 2015. Specifically, the highly flexible algorithm automatically determines the number of regimes for any...

Measuring and allocating risk properly are crucial for performance evaluation and internal capital allocation of portfolios held by banks, insurance companies, investment funds and other entities subject to financial risk. We show that by using a coherent measure of risk it is impossible to...

We consider a situation in which agents have mutual claims on each other, summarized in a liability matrix. Agents' assets might be insufficient to satisfy their liabilities leading to defaults. In case of default, bankruptcy rules are used to specify the way agents are going to be rationed. A...

Present low interest rates environment brings about numerous economic effects. Insurance companies are also strongly affected, since traditional insurance products often provide guaranteed returns to policyholders. As guaranteed returns are related to market interest rates, the question about...

We investigate how the spectral risk measure associated with holding stocks rather than a riskfree deposit, depends on the holding period. Previous papers have shown that within a limited class of spectral risk measures, and when the stock price follows specific processes, spectral risk becomes...

At first glance, the past few decades of the life insurance market in Hungary (and probably in the majority of the European, or at least Central-Eastern European countries) give the impression that annuity insurance is a marginal product that is not worthy of special attention, since most people...

This paper presents a model in which the effects of insurance risk on external (market) risk and internal (capital allocation related) risk can be compared. The model highlights that the composition of the insurance portfolio within an insurance group may not only affect internal capital...
