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 investigates the momentum and reversal signals in exchange rate jumps in currency markets. Following exchange rate jumps, currencies from emerging markets appreciate, but currencies from developed economies depreciate. Stepwise multiple testing confirms non-jump exchange rate changes...

We present empirical evidence that collective investor behavior can be inferred from large-scale Wikipedia search data for individual-level stocks. Using Shannon transfer entropy, a model-free measure that considers any kind of statistical dependence between time series, we investigate the...

Bubbles can persist because investors are better off riding bubbles. We define bubbles in a natural way as significant, prolonged deviations from fundamental values measured by the well-known asset pricing models. Our real-time bubble detection system shows that –using US industry returns–...

Using a sample of domestic U.S. equity mutual funds, we find strong evidence that investors respond to managerial replacements. We find that the top performing funds that have a change in management subsequently have lower flows compared to funds of which the manager is retained. On top of that,...

How is it possible that exchange rates move in the long run towards fundamentals, while professionals form consistently irrational exchange rate expectations? We look at this puzzle from a different perspective by analyzing investor sentiment in the US-dollar market. First, long-horizon...

We investigate the relation between the EUR/HUF exchange rate on the one hand and news announcements and order flow on the other hand using intraday data. We extend the existing literature on foreign exchange market microstructure by considering a small open transition economy. We find that the...

We develop a novel financial market model in which the stock markets of two countries are linked via and with the foreign exchange market. To be precise, there are domestic and foreign speculators in each of the two stock markets which rely either on linear technical or linear fundamental...
