Expected returns should not only include rewards for accepting the risk of a potential downside loss, but also discounts for potential upside gains. Since investors care differently about upside gains versus downside losses, they require a risk premium for bearing the relative downside risk. We...

Current practice largely follows restrictive approaches to market risk measurement, such as historical simulation or RiskMetrics. In contrast, we propose flexible methods that exploit recent developments in financial econometrics and are likely to produce more accurate risk assessments, treating...

This article empirically investigates the volatility spillover of stock returns from the market to disaggregated industry sectors. Seventeen sectors from the US and UK stock markets are estimated by the GARCH technique based on daily data from 1973 to 2008. The key findings are two-fold. In the...

In the paper we introduce an empirical approximation of the log-optimal investment strategy that guarantees an almost optimal growth rate of investments. The proposed strategy also considers the effects of portfolio rearrangement costs on growth optimality and advises a suboptimal portfolio for...

We introduce a new approach for modelling risk dependence. The methods we describe are applicable to all risk types but are motivated by a need to robustly assess the dependence between operational and other risks such as market and credit.We show through a practical example how the technique...

This study is an attempt to measure volatilities among regional stock markets and to establish a relationship between stock returns and volatility, and to rank these markets with respect to volatility. For this purpose, six markets are considered i.e. KSE100, Sensex, Nikkei225, Hangseng,...

Arbitrage pricing model (APT) is one of the models that describe risk of investment on the capital market. The model has been widely used in the developed economies. The paper presents an application of the APT model on the Polish capital market, in particular on the stock investment funds. The...

The starting point in this research in the analysis of dynamic and structure of assets of investment funds in particular types of funds (assets, hybrids, money market funds, stable growth funds). Analyzing time series of assets of funds the tendency of growth can be noticed. The tendency is...

This paper focuses on simulation-based inference for the time-deformation models directed by a duration process. In order to describe the heavy tail property of the time series of financial asset returns, the innovation of the observation equation is assumed to have a Student-t distribution....

This paper proposes a parsimonious threshold stochastic volatility (SV) model for financial asset returns. Instead of imposing a threshold value on the dynamics of the latent volatility process of the SV model, we assume that the innovation of the mean equation follows a threshold distribution...
