We examine contemporaneous jumps (cojumps) among individual stocks and a proxy for the market portfolio. We show, through a Monte Carlo study, that using intraday jump tests and a coexceedance criterion to detect cojumps has a power similar to the cojump test proposed by Bollerslev et al....

Studies find price increases for additions to the S&P 500 index but no decreases for deletions. Additions come with good earnings news, suggesting these studies are not just measuring an indexing effect. We develop a regression discontinuity design using Russell Indices for cleaner...

This paper investigates whether investor sentiment can explain stock returns on the German stock market. Based on a principal component analysis, we construct a sentiment indicator that condenses information of several well-known sentiment proxies. We show that this indicator explains the return...

This paper examines the impact of illiquidity on equity returns on the German stock market. Since illiquidity has many facets, we cover the whole spectrum of illiquidity measures: trading speed, trading costs, trading quantity, and price impact. Based on these illiquidity measures we construct...

We analyze the evolution and price implications of aggregate sectorial holdings of stocks, using detailed information on the universe of publicly traded stocks in the euro area. We document that: i) households’ (HH) direct holdings represent a higher fraction of total ownership in domestic...

Much work in finance is devoted to identifying characteristics of firms, such as measures of fundamentals and beliefs, that explain differences in asset prices and expected returns. We develop a framework to quantitatively trace the connection between valuations, expected returns, and...

Extensive literature investigates the predictability of U.S. equity returns. This does not imply, however, that the results are equally valid for the German equity market. Judith Klähn's central theory is that the German stock market is not comparable to Wall Street. She proves that some of the...
