Short-term persistence in hybrid mutual fund performance: The role of style-shifting abilities

Journal of Banking & Finance 2013 37(7), 2314-2328
Our study analyzes the performance of hybrid mutual funds. Based on two extended Carhart models we determine total fund performance by comparing fund returns to investable fund-specific style benchmarks. Using daily returns and a quarterly measurement interval, we present an innovative return-based approach to decompose total performance into in-quarter abnormal performance and style-shifting performance. In addition, we split total style-shifting performance into active and passive components. In this context, we confirm possible benefits of these performance measures by analyzing several simulated investment strategies. Our empirical study covers 520 hybrid mutual funds from 10/1998 to 12/2009 and shows that hybrid mutual funds (i) do not outperform their benchmarks on average, (ii) partially show positive in-quarter abnormal performance and style-shifting abilities, and (iii) exhibit short-term persistence in in-quarter abnormal performance but not in style-shifting abilities.

Survivorship Bias and Mutual Fund Performance: Relevance, Significance, and Methodical Differences

Review of Finance 2011 15(2), 441-474
This is the first paper systematically calculating, testing and explaining different definitions of the survivorship bias in fund performance. We document that the survival-performance-relation is stronger for small funds and we find significant under-performance of non-survivors but no significant out-performance of new funds. Survivorship bias is still a problem as well in other fields of research, e.g., in countries where survivorship bias-free data is not available and because certain methods require truncated data. This paper provides guidance on how to deal with and reduce survivorship bias in empirical studies.

Performance of international and global equity mutual funds: Do country momentum and sector momentum matter?

Journal of Banking & Finance 2014 43, 58-77 open access
This is the first paper analyzing the impact of index momentum factors on the performance of international and global equity funds. Extending an international, index-based version of the Fama and French (1993) three-factor model by adding the factors of country momentum and sector momentum, we find that more than 50% of funds exhibit significant exposure to at least one of these factors. Including both new factors in performance evaluation clearly impacts results when analyzing (i) the risk-adjusted performance, (ii) the performance persistence of funds, and (iii) luck versus skill in the cross-section of funds. Our main results are robust against models which additionally cover a stock-based momentum factor as well as single country, regional and sector factors.

The price-setting behavior of banks: An analysis of open-end leverage certificates on the German market

Journal of Banking & Finance 2009 33(5), 874-882 open access
This paper presents the first analysis of open-end leverage certificates on the German market. The major innovations of these certificates are twofold. First, issuers announce a price-setting formula according to which they are willing to buy and sell the certificates over time. Second, the product’s lifetime is potentially endless. Our main findings are that the price-setting formula is (i) designed to strongly favor the issuer and (ii) is consistent with the main outcome of the ‘life cycle hypothesis’ for structured financial products [Stoimenov, P.A., Wilkens, S., 2005. Are structured products ‘fairly’ priced? An analysis of the German market for equity-linked instruments. Journal of Banking and Finance 29, 2971–2993]. (iii) This holds for different product features and also in the presence of issuers’ credit risk and jump risk in the underlying.
