Available in PDF, EPUB and Kindle. Book excerpt: In this article, the authors conduct a horse race between representative risk parity portfolios and other asset allocation strategies, including equal weighting, minimum variance, mean-variance optimization, and the classic 60/40 equity/bond portfolio. They find that the traditional risk parity portfolio construction does not consistently outperform (in terms of risk-adjusted return) equal weighting or a model pension fund portfolio anchored to the 60/40 equity/bond portfolio structure. However, it does significantly outperform such optimized allocation strategies as minimum variance and mean-variance efficient portfolios. Over the last 30 years, the Sharpe ratios of the risk parity and the equal-weighting portfolios have been much more stable across decade-long subperiods than either the 60/40 portfolio or the optimized portfolios. Although risk parity performs on par with equal weighting, it does provide better diversification in terms of risk allocation and thus warrants further consideration as an asset allocation strategy. The authors show, however, that the performance of the risk parity strategy can be highly dependent on the investment universe. Thus, to execute risk parity successfully, the careful selection of asset classes is critical, which, for the time being, remains an art rather than a formulaic exercise based on theory.

Download or read book Advances in Risk Parity Portfolio Optimization written by Giorgio Costa Del Pozo and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk parity is an asset allocation strategy that seeks to equalize the risk contributions of the constituent assets in a portfolio. The resulting portfolio is fully diversified from a risk perspective. However, like other asset allocation strategies, risk parity is susceptible to estimation errors. Moreover, its mathematical formulation imposes some fundamental limitations. This thesis aims to modernize risk parity by addressing all of the aforementioned issues. We address the susceptibility to estimation errors through three different frameworks. First, we introduce a robust framework that quantifies estimation error and embeds this information during optimization to construct a robust risk parity portfolio. Our second framework takes a different approach, introducing robustness during the parameter estimation step. This is formulated as a game-theoretic minimax problem to make an optimal investment decision against the most adversarial estimate of our parameters. Our third framework improves the quality of our estimated parameters before optimization takes place. We posit that we can embed the cyclical information of financial markets directly into our estimates, resulting in risk parity portfolios aligned with the current market regime. The result is a Markov regime-switching factor model of asset returns from which we can naturally derive regime-dependent parameters for use during optimization. The final component of this thesis addresses the fundamental limitations of risk parity: its lack of accountability for the investor's risk and reward appetite and its prohibition of short sales. We propose a generalized risk parity framework where the investor's risk and reward appetite define our objective, while still enforcing a desirable degree of risk-based diversification. Moreover, we propose an algorithm that allows us to consider portfolios with short positions. Thus, our generalized framework addresses the fundamental limitations of risk parity while retaining the desirable property of risk-based diversification. The frameworks proposed in this thesis can be used independently or in tandem, depending on the investor's needs and goals. The unifying subject of this thesis is to advance risk parity by addressing its fundamental weaknesses. This is achieved by proposing different frameworks and algorithms, with the overarching property of preserving the interpretability and computational tractability of our solutions.

Download or read book Metaheuristic Approaches to Portfolio Optimization written by Ray, Jhuma and published by IGI Global. This book was released on 2019-06-22 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Control of an impartial balance between risks and returns has become important for investors, and having a combination of financial instruments within a portfolio is an advantage. Portfolio management has thus become very important for reaching a resolution in high-risk investment opportunities and addressing the risk-reward tradeoff by maximizing returns and minimizing risks within a given investment period for a variety of assets. Metaheuristic Approaches to Portfolio Optimization is an essential reference source that examines the proper selection of financial instruments in a financial portfolio management scenario in terms of metaheuristic approaches. It also explores common measures used for the evaluation of risks/returns of portfolios in real-life situations. Featuring research on topics such as closed-end funds, asset allocation, and risk-return paradigm, this book is ideally designed for investors, financial professionals, money managers, accountants, students, professionals, and researchers.

This book was released on 2006-07-02 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Portfolio Management with Heuristic Optimization consist of two parts. The first part (Foundations) deals with the foundations of portfolio optimization, its assumptions, approaches and the limitations when "traditional" optimization techniques are to be applied. In addition, the basic concepts of several heuristic optimization techniques are presented along with examples of how to implement them for financial optimization problems. The second part (Applications and Contributions) consists of five chapters, covering different problems in financial optimization: the effects of (linear, proportional and combined) transaction costs together with integer constraints and limitations on the initital endowment to be invested; the diversification in small portfolios; the effect of cardinality constraints on the Markowitz efficient line; the effects (and hidden risks) of Value-at-Risk when used the relevant risk constraint; the problem factor selection for the Arbitrage Pricing Theory.
Download or read book Equal Risk Bounding Is Better Than Risk Parity for Portfolio Selection written by Francesco Cesarone and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk Parity (RP), also called equally weighted risk contribution, is a recent approach to risk diversification for portfolio selection. RP is based on the principle that the fractions of the capital invested in each asset should be chosen so as to make the total risk contributions of all assets equal among them. We show here that the Risk Parity approach is theoretically dominated by an alternative similar approach that does not actually require equally weighted risk contribution of all assets but only an equal upper bound on all such risks. This alternative approach, called Equal Risk Bounding (ERB), requires the solution of a nonconvex quadratically constrained optimization problem. The ERB approach, while starting from different requirements, turns out to be strictly linked to the RP approach. Indeed, when short selling is allowed, we prove that an ERB portfolio is actually an RP portfolio with minimum variance. When short selling is not allowed, there is a unique RP portfolio and it contains all assets in the market. In this case, the ERB approach might lead to the RP portfolio or it might lead to portfolios with smaller variance that do not contain all assets, and where the risk contributions of each asset included in the portfolio is strictly smaller than in the RP portfolio. We define a new riskiness index for assets that allows to identify those assets that are more likely to be excluded from the ERB portfolio. With these tools we then provide an exact method for small size nonconvex ERB models and a very efficient and accurate heuristic for larger problems of this type. In the case of a common constant pairwise correlation among all assets, a closed form solution to the ERB model is obtained and used to perform a parametric analysis when varying the level of correlation. The practical advantages of the ERB approach over the RP strategy are illustrated with some numerical examples. Computational experience on real-world and on simulated data confirms accuracy and efficiency of our heuristic approach to the ERB model also in comparison with some state-of-the-art local and global optimization codes.
Download or read book Risk Based Approaches to Asset Allocation written by Maria Debora Braga and published by Springer. This book was released on 2015-12-10 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the concepts and applications of risk-based asset allocation. Markowitz’s traditional approach to asset allocation suffers from serious drawbacks when implemented. These mainly arise from the estimation risk associated with the necessary input the most critical being expected returns. With the financial crisis, there has been an increasing interest in asset allocation approaches that don’t need expected returns as input, known as risk-based approaches. The book provides an analysis of the different solutions that fit this description: the equal-weighting approach, the global minimum-variance approach, the most diversified portfolio approach and the risk parity approach. In addition to a theoretical discussion of these, it presents practical applications in different investment environments. Three different evaluation dimensions are considered to put these approaches to the test: financial efficiency, diversification and portfolio stability.
Download or read book Risk Parity Portfolio written by Saul Sala Peñalver and published by . This book was released on 2015 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: Capitalization-weighted indexes are the most common way to gain access to broad equity market performance. However, interest in risk based investing has grown steadily in the recent post-crisis years as investors seek to overcome the limitations of traditional approaches to asset allocation. Despite the interest, there remains confusion about how to implement these strategies in any investor's portfolio, and even more when we want to implement it into a particular asset class. This paper compares some risk-based indexation methodologies, where risk parity takes an important role, and illustrates these issues as it applies to the Ibex 35 universe. We also use the typical capitalization-weighted index as a benchmark. Using 10 years of data, we show that risk parity portfolios outperform all the underlying portfolios on an absolute and risk adjusted basis.
Download or read book Introducing Expected Returns Into Risk Parity Portfolios written by Thierry Roncalli and published by . This book was released on 2014 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk parity is an allocation method used to build diversified portfolios that does not rely on any assumptions of expected returns, thus placing risk management at the heart of the strategy. This explains why risk parity became a popular investment model after the global financial crisis in 2008. However, risk parity has also been criticized because it focuses on managing risk concentration rather than portfolio performance, and is therefore seen as being closer to passive management than active management. In this article, we show how to introduce assumptions of expected returns into risk parity portfolios. To do this, we consider a generalized risk measure that takes into account both the portfolio return and volatility. However, the trade-off between performance and volatility contributions creates some difficulty, while the risk budgeting problem must be clearly defined. After deriving the theoretical properties of such risk budgeting portfolios, we apply this new model to asset allocation. First, we consider long-term investment policy and the determination of strategic asset allocation. We then consider dynamic allocation and show how to build risk parity funds that depend on expected returns.

Download or read book Generalized Risk Parity Portfolio Optimization written by Giorgio Costa and published by . This book was released on 2020 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: The risk parity solution to the asset allocation problem yields portfolios where the risk contribution from each asset is made equal. We consider a generalized approach to this problem. First, we set an objective that seeks to maximize the portfolio expected return while minimizing portfolio risk. Second, we relax the risk parity condition and instead bound the risk dispersion of the constituents within a predefined limit. This allows an investor to prescribe a desired risk dispersion range, yielding a portfolio with an optimal risk-return profile that is still well-diversified from a risk-based standpoint. We add robustness to our framework by introducing an ellipsoidal uncertainty structure around our estimated asset expected returns to mitigate estimation error. Our proposed framework does not impose any restrictions on short selling. A limitation of risk parity is that allowing of short sales leads to a non-convex problem. However, we propose an approach that relaxes our generalized risk parity model into a convex semi-definite program. We proceed to tighten this relaxation sequentially through the alternating direction method of multipliers. This procedure iterates between the convex optimization problem and the non-convex problem with a rank constraint. In addition, we can exploit this structure to solve the non-convex problem analytically and efficiently during every iteration. Numerical results suggest that this algorithm converges to a higher quality optimal solution when compared to the competing non-convex problem, and can also yield a higher ex post risk-adjusted rate of return.
Download or read book The Use of Risk Budgets in Portfolio Optimization written by Albina Unger and published by Springer. This book was released on 2014-09-10 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk budgeting models set risk diversification as objective in portfolio allocation and are mainly promoted from the asset management industry. Albina Unger examines the portfolios based on different risk measures in several aspects from the academic perspective (Utility, Performance, Risk, Different Market Phases, Robustness, and Factor Exposures) to investigate the use of these models for asset allocation. Beside the risk budgeting models, alternatives of risk-based investment styles are also presented and examined. The results show that equalizing the risk across the assets does not prevent losses, especially in crisis periods and the performance can mainly be explained by exposures to known asset pricing factors. Thus, the advantages of these approaches compared to known minimum risk portfolios are doubtful.
Download or read book Factor Based Approaches to Risk Parity written by Peter Williams and published by . This book was released on 2014 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper finds that factor based risk parity portfolios are able to outperform other standard asset allocation approaches, including 60/40 and long-only risk parity. By using a group of factors which have negligible correlations with each other and the market, this portfolio generates a stable return stream with little exposure to macroeconomic risks. If these factors are dynamically scaled according to their conditional volatility the portfolio's performance markedly increases. While this portfolio is composed of well known factors it exhibits 'alpha through construction' by scaling out of strategies when their expected returns are lowest and using minimally correlated components.
Download or read book Risk Parity and Beyond From Asset Allocation to Risk Allocation Decisions written by Romain Deguest and published by . This book was released on 2013 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: While it is often argued that allocation decisions can be best expressed in terms of exposure to rewarded risk factors, as opposed to somewhat arbitrary asset class decompositions, the practical implications of this paradigm shift for the optimal design of the policy portfolio still remain largely unexplored. This paper aims at analyzing whether the use of uncorrelated underlying risk factors, as opposed to correlated asset returns, can lead to a more efficient framework for measuring and managing portfolio diversification. Following Meucci (2009), we use the entropy of the factor exposure distribution as the number of uncorrelated bets (also known as the effective number of bets, or ENB in short), implicitly embedded within a given asset allocation decision. We present a set of formal results regarding the existence and unicity of portfolios designed to achieve the maximum effective number of bets. We also provide empirical evidence that incorporating constraints, or target levels, on a portfolio effective number of bets generates an improvement in out-of-sample risk-adjusted performance with respect to standard mean-variance analysis.
