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.

Available in PDF, EPUB and Kindle. Book excerpt: Although portfolio management didn't change much during the 40 years after the seminal works of Markowitz and Sharpe, the development of risk budgeting techniques marked an important milestone in the deepening of the relationship between risk and asset management.

Download or read book Risk Parity Return Trade off in Relaxed Risk Parity Portfolio Optimization written by Vaughn Edward Gambeta and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper formulates a relaxed risk parity optimization model to control the balance of risk parity violation against the total portfolio performance. Risk parity is criticized as being conservative and it is improved by re-introducing the asset expected returns into the model and permitting the portfolio to violate the risk parity condition. The incorporation of an explicit target return goal into a second-order-cone model of a risk parity optimization is proposed. When the target return is greater than risk parity return a violation to risk parity allocations occurs that is controlled using a computational construct to obtain near risk parity portfolios to retain risk parity like traits. This model is used to demonstrate empirically that higher returns can be achieved without the risk contributions deviating dramatically from the risk parity allocations. This study also reveals that the relaxed risk parity model exhibits advantageous traits of robustness to 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 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.

This book was released on 2015-06-10 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents solutions to the general problem of single period portfolio optimization. It introduces different linear models, arising from different performance measures, and the mixed integer linear models resulting from the introduction of real features. Other linear models, such as models for portfolio rebalancing and index tracking, are also covered. The book discusses computational issues and provides a theoretical framework, including the concepts of risk-averse preferences, stochastic dominance and coherent risk measures. The material is presented in a style that requires no background in finance or in portfolio optimization; some experience in linear and mixed integer models, however, is required. The book is thoroughly didactic, supplementing the concepts with comments and illustrative examples.

Book excerpt: Diversification provides a well-known way of getting something close to a free lunch: by spreading money across different kinds of investments, investors can earn the same return with lower risk (or a much higher return for the same amount of risk). This strategy, introduced nearly fifty years ago, led to such strategies as index funds. What if we were all missing out on another free lunch that’s right under our noses? InLifecycle Investing, Barry Nalebuff and Ian Ayres-two of the most innovative thinkers in business, law, and economics-have developed tools that will allow nearly any investor to diversify their portfolios over time.
