This book was released on 2013 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strategic asset allocations are based on the longer term view of the assets return and the tactical asset allocation captures the short term views from the market environment. Although numerous studies are conducted on these approaches separately, there are no studies which summarise the results of a combined approach. The studies conducted assume that the other model is readily available. In this paper, we would like to address this by analysing the effects of overlay approaches applied to the equal risk-weighted and equal-weighted portfolios. Minimum CVAR equal risk-weighted portfolio provides an attractive compromise between the good risk-adjusted return properties of the minimum risk portfolio and the positive return potential and low portfolio turnover of an equally weighted portfolio and this makes it a good candidate for a strategic portfolio. To enhance its returns, we constructed overlay approaches using value and momentum signals. We compared the results of the constructed portfolios against the equal-weighted portfolios with overlays and found that different overlays work well with different base portfolios. We found that the value strategy enhanced the risk-adjusted returns of an equal risk-weighted portfolio but not an equal-weighted portfolio. Similarly, we observed that a combined momentum-value strategy works well with the equal-weighted portfolio but not with the equal risk-weighted portfolio. We also found that the momentum strategy works well with both the portfolios. We extended our analysis to different crisis-periods and observed that the combined overlay has a positive effect on already well performing equal risk-weighted portfolios but not on the equal-weighted portfolios. We observed the reverse during the bull periods. Thus we conclude that the overlays add value to the strategic portfolios and the challenge is in identifying the right one under a given macro-economic condition.

Available in PDF, EPUB and Kindle. Book excerpt: The reliance on estimated input parameters for the Markowitz portfolio optimization is well documented to result in extreme and highly unstable allocations that perform poorly in an out-of-sample context. Therefore, the investor's attention is increasingly drawn towards equally-weighted and respectively minimum-variance strategies since their construction does not rely on an explicit modelling of expected returns. This paper examines two alternative risk-weighted portfolio strategies that restrict their input requirements to the model of risk. The equally-weighted risk contribution portfolio (ERC) introduced by Maillard, Roncalli and Teiletche (2009) maximizes the dispersion in risks by equalizing the ex-ante total risk contributions of every portfolio component and thus achieves superior diversification. The Eigenvector strategy (EIG) relies on the noise-dressing methodology proposed by Laloux et al. (1999) and allocates the invested wealth subject to maximizing the dispersion of the portfolios' exposures to the significant uncorrelated sources of risk (the effective number of uncorrelated bets). Based on two samples consisting of the daily prices of the constituents of the EURO STOXX 50 Price Index (ranging from 1995-2011) and respectively the Swiss Market Price Index (2000-2011), an empirical back test relying on an rolling sample approach to parameter estimation confirms the particular advantageous downside characteristics of the ERC strategy and validates its standing as an attractive alternative to the equally-weighted and the minimum-variance strategies, respectively. Due to its lack of robustness, the EIG strategy seems to require further refinement in order to represent a satisfactory alternative to the risk-weighted strategies.

Available in PDF, EPUB and Kindle. Book excerpt: The equal-risk-contribution, inverse-volatility weighted, maximum-diversification and minimum-variance portfolio weights are all direct functions of the estimated covariance matrix. We perform a Monte Carlo study to assess the impact of covariance matrix misspecification to these risk-based portfolios. Our results show that the equal-risk-contribution and inverse-volatility weighted portfolio weights are relatively robust to covariance misspecification, but that the minimum-variance and maximum-diversification portfolios are highly sensitive to errors in the estimated variance and correlation, respectively.

Download or read book Characteristic based Mean variance Portfolio Choice written by Erik Hjalmarsson and published by . This book was released on 2009 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: We study empirical mean-variance optimization when the portfolio weights are restricted to be direct functions of underlying stock characteristics such as value and momentum. The closed-form solution to the portfolio weights estimator shows that the portfolio problem in this case reduces to a mean-variance analysis of assets with returns given by single-characteristic strategies (e.g., momentum or value). In an empirical application to international stock return indexes, we show that the direct approach to estimating portfolio weights clearly beats a naive regression-based approach that models the conditional mean. However, a portfolio based on equal weights of the single-characteristic strategies performs about as well, and sometimes better, than the direct estimation approach, highlighting again the difficulties in beating the equal-weighted case in mean-variance analysis. The empirical results also highlight the potential for "stock-picking" in international indexes, using characteristics such as value and momentum, with the characteristic-based portfolios obtaining Sharpe ratios approximately three times larger than the world market.

Krell, President and CEO, International Securities Exchange "How I Became a Quant should be must reading for all students with a quantitative aptitude. It provides fascinating examples of the dynamic career opportunities potentially open to anyone with the skills and passion for quantitative analysis." --Roy D. Henriksson, Chief Investment Officer, Advanced Portfolio Management "Quants"--those who design and implement mathematical models for the pricing of derivatives, assessment of risk, or prediction of market movements--are the backbone of today's investment industry. As the greater volatility of current financial markets has driven investors to seek shelter from increasing uncertainty, the quant revolution has given people the opportunity to avoid unwanted financial risk by literally trading it away, or more specifically, paying someone else to take on the unwanted risk. How I Became a Quant reveals the faces behind the quant revolution, offering you?the?chance to learn firsthand what it's like to be a?quant today. In this fascinating collection of Wall Street war stories, more than two dozen quants detail their roots, roles, and contributions, explaining what they do and how they do it, as well as outlining the sometimes unexpected paths they have followed from the halls of academia to the front lines of an investment revolution.

Download or read book Efficient Asset Management written by Richard O. Michaud and published by Oxford University Press. This book was released on 2008-03-03 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: In spite of theoretical benefits, Markowitz mean-variance (MV) optimized portfolios often fail to meet practical investment goals of marketability, usability, and performance, prompting many investors to seek simpler alternatives. Financial experts Richard and Robert Michaud demonstrate that the limitations of MV optimization are not the result of conceptual flaws in Markowitz theory but unrealistic representation of investment information. What is missing is a realistic treatment of estimation error in the optimization and rebalancing process. The text provides a non-technical review of classical Markowitz optimization and traditional objections. The authors demonstrate that in practice the single most important limitation of MV optimization is oversensitivity to estimation error. Portfolio optimization requires a modern statistical perspective. Efficient Asset Management, Second Edition uses Monte Carlo resampling to address information uncertainty and define Resampled Efficiency (RE) technology. RE optimized portfolios represent a new definition of portfolio optimality that is more investment intuitive, robust, and provably investment effective. RE rebalancing provides the first rigorous portfolio trading, monitoring, and asset importance rules, avoiding widespread ad hoc methods in current practice. The Second Edition resolves several open issues and misunderstandings that have emerged since the original edition. The new edition includes new proofs of effectiveness, substantial revisions of statistical estimation, extensive discussion of long-short optimization, and new tools for dealing with estimation error in applications and enhancing computational efficiency. RE optimization is shown to be a Bayesian-based generalization and enhancement of Markowitz's solution. RE technology corrects many current practices that may adversely impact the investment value of trillions of dollars under current asset management. RE optimization technology may also be useful in other financial optimizations and more generally in multivariate estimation contexts of information uncertainty with Bayesian linear constraints. Michaud and Michaud's new book includes numerous additional proposals to enhance investment value including Stein and Bayesian methods for improved input estimation, the use of portfolio priors, and an economic perspective for asset-liability optimization. Applications include investment policy, asset allocation, and equity portfolio optimization. A simple global asset allocation problem illustrates portfolio optimization techniques. A final chapter includes practical advice for avoiding simple portfolio design errors. With its important implications for investment practice, Efficient Asset Management 's highly intuitive yet rigorous approach to defining optimal portfolios will appeal to investment management executives, consultants, brokers, and anyone seeking to stay abreast of current investment technology. Through practical examples and illustrations, Michaud and Michaud update the practice of optimization for modern investment management.

Download or read book Applications of Stochastic Optimal Control to Economics and Finance written by Salvatore Federico and published by . This book was released on 2020-06-23 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a world dominated by uncertainty, modeling and understanding the optimal behavior of agents is of the utmost importance. Many problems in economics, finance, and actuarial science naturally require decision makers to undertake choices in stochastic environments. Examples include optimal individual consumption and retirement choices, optimal management of portfolios and risk, hedging, optimal timing issues in pricing American options, and investment decisions. Stochastic control theory provides the methods and results to tackle all such problems. This book is a collection of the papers published in the Special Issue "Applications of Stochastic Optimal Control to Economics and Finance", which appeared in the open access journal Risks in 2019. It contains seven peer-reviewed papers dealing with stochastic control models motivated by important questions in economics and finance. Each model is rigorously mathematically funded and treated, and the numerical methods are employed to derive the optimal solution. The topics of the book's chapters range from optimal public debt management to optimal reinsurance, real options in energy markets, and optimal portfolio choice in partial and complete information settings. From a mathematical point of view, techniques and arguments of dynamic programming theory, filtering theory, optimal stopping, one-dimensional diffusions and multi-dimensional jump processes are used.
