Download or read book An Exact Test of the Improvement of the Minimum Variance Portfolio written by Paskalis Glabadanidis and published by . This book was released on 2019 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: I propose an exact finite sample test of the risk reduction of the global minimum variance (GMV) portfolio. The GMV test statistic has a straightforward geometric and portfolio interpretation and complements the celebrated GRS test in Gibbons, Ross and Shanken (1989). In practical applications, the GMV test leads to a rejection of the null hypothesis of no improvement in the GMV portfolio more often than the GRS test rejects the null hypothesis of no improvement in the risk-return profile of the tangent portfolio. The power of the GMV test increases with the variance reduction of the global minimum variance portfolio. Using test asset returns scaled by pre-determined instrumental variables is equivalent to increasing the overall number of test assets and leads to substantial power gains.

Available in PDF, EPUB and Kindle. Book excerpt: I propose a new finite sample mean-variance efficiency test based on the risk reduction of the global minimum variance (GMV) portfolio. The GMV test statistic has a straightforward geometric and portfolio interpretation and complements nicely the celebrated GRS test in Gibbons, Ross and Shanken (1989). In practical applications, the GMV test leads to a rejection of the null hypothesis of mean-variance efficiency more often than the GRS test. This imposes a higher bar on testing the efficiency of a given portfolio. The power of the GMV test increases in the improvement of the global minimum variance portfolio. Using test asset returns scaled by pre-determined instrumental variables is equivalent to increasing the overall number of test assets and leads to substantial power gains. I also present asymptotic versions of both tests as well as a joint test leading to a test of mean-variance spanning.

Download or read book An Improvement of the Global Minimum Variance Portfolio Using a Black Litterman Approach written by Maximilian Adelmann and published by . This book was released on 2016 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Asset management companies are constantly searching for portfolio optimization models that are on the one hand clear and intuitive and on the other provide high and reliable returns. This paper presents a modified version of the well-known Black-Litterman portfolio optimization approach. Unlike in the original model, the intuitive global minimum variance (GMV) portfolio serves as the reference portfolio. The introduction of a general rule for investors' views in combination with a simplification of the original Black-Litterman approach facilitates the implementation of the model and enables us to remove so-called dead assets from the GMV portfolio. As an additional advantageous feature our model is only based on variance-covariance estimations, and relative return estimations for our general rule. A numerical application of our modified Black-Litterman model to empirical data sets demonstrates that portfolios based on the model clearly outperform the GMV portfolio and the 1/N portfolio in terms of compound annual returns and out-of-sample Sharpe ratios.
Download or read book Hedge Funds and Financial Markets written by Julian Holler and published by Springer Science & Business Media. This book was released on 2012-01-02 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hedge funds have started to play an important role in financial markets during the last decade. They have affected important aspects of financial intermediation such as asset allocation decisions and corporate governance. Julian Holler provides an excellent theoretical and empirical analysis of these issues. His analysis offers strong support that hedge funds enable investors to improve asset allocation decisions. Consequently, hedge funds are an interesting alternative asset class for institutional investors. In contrast to results for the U.S. capital market his research provides evidence that hedge fund activism does not persistently increase the value of firms in Germany. This result suggests that the institutional environment has a strong influence on the effectiveness of corporate governance mechanisms.
Download or read book Funds of Hedge Funds written by Greg N. Gregoriou and published by Elsevier. This book was released on 2011-04-01 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: With about $450 billion in assets, funds of hedge funds are the most recent darling of investors. While hedge funds carry high risk for the promise of high returns they are designed for the very rich and for large institutional investors such as pension funds. A Fund of Hedge Funds (FOF) spreads investments among a number of hedge funds to reduce risk and provide diversification, while maintaining the potential for higher than average returns. Odds are that some pension fund of yours is invested heavily in these products, and more recently these FOFs have been opened to more and more individual investors in offshore jurisdictions with lower minimum entry levels. Since this is a new and extremely fast-moving financial phenomenon, academic research has just begun in earnest, and this is the first book to present rigorous academic research by some of the leading lights in academic finance, carefully analyzing the broad array of issues involved in FOFs. * With over $450 billion in assets, hedge funds of funds are the darling of investors * First book to present rigorous academic research about funds of funds * Leading lights in academic finance from around the world analyze the broad array of issues involved in funds of funds

Download or read book Testing Portfolio Efficiency Under Alternative Distributions written by Taras Bodnar and published by . This book was released on 2004 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: The exact density of linear combinations of global minimum variance portfolio weights is derived. The exact finite-sample statistical procedure to test general linear restrictions of portfolio weights is obtained. The results are generalized to elliptically contoured distributions, which extends a number of financial theorems, to non-normal distributions. It is proved that the proposed global minimum variance portfolio weights estimator and testing statistics are financially and statistically interpreted for the heavy-tail distributions with tail index less than two. We show that higher moments of the estimator and testing statistics do exist for all elliptically symmetric stable distributions.
Download or read book Asset Pricing written by John H. Cochrane and published by Princeton University Press. This book was released on 2009-04-11 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the prestigious Paul A. Samuelson Award for scholarly writing on lifelong financial security, John Cochrane's Asset Pricing now appears in a revised edition that unifies and brings the science of asset pricing up to date for advanced students and professionals. Cochrane traces the pricing of all assets back to a single idea--price equals expected discounted payoff--that captures the macro-economic risks underlying each security's value. By using a single, stochastic discount factor rather than a separate set of tricks for each asset class, Cochrane builds a unified account of modern asset pricing. He presents applications to stocks, bonds, and options. Each model--consumption based, CAPM, multifactor, term structure, and option pricing--is derived as a different specification of the discounted factor. The discount factor framework also leads to a state-space geometry for mean-variance frontiers and asset pricing models. It puts payoffs in different states of nature on the axes rather than mean and variance of return, leading to a new and conveniently linear geometrical representation of asset pricing ideas. Cochrane approaches empirical work with the Generalized Method of Moments, which studies sample average prices and discounted payoffs to determine whether price does equal expected discounted payoff. He translates between the discount factor, GMM, and state-space language and the beta, mean-variance, and regression language common in empirical work and earlier theory. The book also includes a review of recent empirical work on return predictability, value and other puzzles in the cross section, and equity premium puzzles and their resolution. Written to be a summary for academics and professionals as well as a textbook, this book condenses and advances recent scholarship in financial economics.

Download or read book The Fama Portfolio written by Eugene F. Fama and published by University of Chicago Press. This book was released on 2017-09-07 with total page 826 pages. Available in PDF, EPUB and Kindle. Book excerpt: Few scholars have been as influential in finance, both as an academic field and an industry, as Eugene Fama. Since writing his groundbreaking 1970 essay on efficient capital markets, Fama has written over 100 papers and books that have been cited hundreds of thousands of times. Yet there is no one collection where one can easily find his best work in all fields. "The Fama Portfolio" will be an outstanding and unprecedented resource in a field that still concentrates mainly on questions stemming from Fama s work: Is the finance industry too large or too small? Why do people continue to pay active managers so much? What accounts for the monstrous amount of trading? Do high-speed traders help or hurt? The ideas, facts, and empirical methods in Fama s work continue to guide these investigations. "The Fama Portfolio" will be a historic and long-lasting collection of some of the finest work ever produced in finance."
