This paper investigates how investor sentiment affects stock market returns and evaluates the predictability power of sentiment indices on U.S. and EU stock market returns. As regards the American example, evidence shows that investor sentiment indices have an economic and statistical...

The correlation of returns for various equity asset classes has been high. In addition, the range or "dispersion" of returns across asset classes - and across sectors within those asset classes - has been low. These factors have made it difficult for active managers to outperform. But dispersion...

We document a highly significant, strongly nonlinear dependence of stock and bond returns on past equity market volatility as measured by the VIX. We propose a new estimator for the shape of the nonlinear forecasting relationship that exploits additional variation in the cross section of...

We take the model of Alfarano et al. (Journal of Economic Dynamics & Control 32, 2008, 101-136) as a prototype agent-based model that allows reproducing the main stylized facts of financial returns. The model does so by combining fundamental news driven by Brownian motion with a minimalistic...

This paper develops a model of heterogeneous agents on an options market. On Paris Option Market, negotiators have different beliefs about future-at the volatility of the underlying. We assume in advance two groups; fundamentalists who believe in mean reversion and Chartists that incorporate...

This research aims to investigate, through simulation models, how the interaction among agents in an artificial stock market can affect the dynamics of asset prices. Thus, the study follows a different methodology for the analysis of prices by exploring the simulation of agents' behavior in an...

The present paper aims to test a new model comparison methodology by calibrating and comparing three agent-based models of financial markets on the daily returns of 18 indices. The models chosen for this empirical application are the herding model of Gilli & Winker, its asymmetric version by...

Within this paper, we analyze the impact of Financial Times Deutschland (FTD) news on stock prices and trading volumes. Based on a sample of all news on German DAX, MDAX and SDAX companies published within the news section of the FTD between 2006 and 2010, our results show that articles that...

We investigate investor's correlated attention as a determinant of excess stock market comovement. We propose a novel proxy, "co-attention", that measures the correlation in demand for market-wide information across stock markets approximated by the Google Search Volume Index (SVI). Our results...
