We document that the variation in market liquidity is an important determinant of momentum crashes that is independent of other known explanations surfaced on this topic. This relationship is driven by the asymmetric large return sensitivity of short-leg of momentum portfolio to changes in...

The paper reviews origins of the approach to pricing derivatives post-crisis by following three papers that have received wide acceptance from practitioners as the theoretical foundations for it - [Piterbarg 2010], [Burgard and Kjaer 2010] and [Burgard and Kjaer 2013].The review reveals several...

We document economically and statistically large 24h pre-ECB announcement re- turns in European equity. For the overall market the respective annual premium (2010 – 2015) was over 6% (Sharpe ratio of 1.5). We show that the pre-ECB return is mainly driven by periods of high uncertainty during...

Asset price bubbles have fascinated economists for decades. In consequence, the literature on bubbles and their detection is abundant, with many researchers taking very opposite positions on the topic, however. This survey gives a structured overview of the two branches of research that have...
