We show that internationally diversified portfolios carry sizeable political risk premia. We use a tail-risk portfolio selection model to obtain political efficient frontiers from skewed return distributions and manage political risk, and design an inference test to draw conclusions. We find...

Controlling and managing potential losses is one of the main objective of the Risk Management. Following Ben Ameur and Prigent (2007) and Chen et al. (2008), and extending the first results by Hamidi et al. (2009) when adopting a risk management approach for defining insurance portfolio...

We investigate simply the usage of clustering method by inverse covariance estimation for asset allocation in finance. Allocation across various sectors of the market (i.e. sector ETF) is usually well understood through the usage of mean variance allocation. However, stocks inside a same sector...

This paper investigates the link between economic state and investment levels in an economy within the premise of a partial equilibrium econometric setup based on the central philosophies of production-based asset pricing model and economic tracking portfolio models. By employing a simple linear...

We introduce the selection of financial portfolios in a nonstationary Gaussian framework that assumes the price process to be modeled by a multifractional Brownian motion (mBm). This process captures the time-changing regularity of the sample paths as a result of the impact of the new...

This paper illustrates how qualitative analysis can be incorporated into quantitative risk measurement in order to construct an expected distribution of hedge fund returns that explicitly allows for market, residual and tail risk. We show how the combination of statistical criteria with...

Investors show different behaviour in falling markets and in rising markets. This paper demonstrates that the beta of individual stocks varies across the entire return distribution and that the variation depends on the frequency of the returns. While there is a symmetric u-shape increase for...

Passive investment strategies basically aim to replicate an underlying benchmark. Thereby, the management usually selects a subset of stocks being employed in the optimization procedure. Apart from the optimization procedure, the stock selection approach determines the stock portfolios's...

Even though a random walk process is from a statistical point of view not predictable, some movements can be correlated with specific events concerning other variables. Then, predictable patterns may arise being dependent on this joint event. There is evidence given that equity price busts being...
