We investigate the relationship between risk-adjusted returns, arbitrage risk and arbitrage asymmetry, and investor sentiment in the European stock market. Under the assumption that idiosyncratic volatility (IVOL) causes arbitrage risk, we analyze the effects of IVOL on the-abnormal returns of...

We report systematic, out-of-sample evidence on the benefits to an already well diversified investor that may derive from further diversification into various hedge fund strategies. We investigate dynamic strategic asset allocation decisions that take into account investors' preferences as well...

We apply a two-step strategy to forecast the dynamics of the volatility surface implicit in option prices to all American-style options written on the stocks that have entered the Dow Jones Industrial Average Index between 2004 and 2016. We explore whether the implied volatilities extracted...

We test whether the unconventional monetary policy (UMP) announcements by the Federal Reserve and the European Central Bank represent a risk factor for the hedge fund industry as a whole and for ten commonly used strategies in particular. Using modified event studies and Markov switching models,...

In this paper we take an empirical asset pricing perspective and investigate the dominant view (possibly, an instinctive reflection of the media hype surrounding the surge of Bitcoin valuations) that cryptocurrencies represent a new asset class, spanning risks and payoffs sufficiently...

At the heart of the portfolio selection problem lies the challenge of accurately estimating asset expected returns and covariance matrices. The classical Black-Litterman model addresses this challenge by combining market equilibrium and investors' views within the Markowitz mean-variance...

We examine whether the dynamics of the implied volatility surface of individual equity options contains exploitable predictability patterns. Predictability in implied volatilities is expected due to the learning behavior of agents in option markets. In particular, we explore the possibility that...
