Certain investor types, particularly those approaching or in retirement, care about the income properties of investment portfolios. This article addresses the income characteristics of equities and bonds and provides a framework for building multi-asset portfolios with varying degrees of income orientation, both ex post, investigating the historical income behavior of equities and bonds, as well as through a forward-looking lens, based on today’s much lower dividend and bond yields. Because bond yields and prices are inversely related, bonds imbed a natural time-diversification property across the two dimensions that income-oriented investors care most about: portfolio income and expected wealth. Despite the long-term growth potential of equity income and the prospect for higher bond yields over the next several years, we still find that a meaningful allocation to bonds is likely optimal for investors with an orientation toward organic portfolio income.
某些投资者类型,特别是那些即将退休或即将退休的投资者,关心投资组合的收入特性。本文阐述了股票和债券的收入特征,并提供了一个框架,用于构建具有不同程度收入导向的多资产投资组合,既可以事后调查股票和债券历史收入行为,也可以基于当今低得多的股息和债券收益率,从前瞻性角度进行研究。由于债券收益率和价格呈负相关,债券在以收入为导向的投资者最关心的两个维度上嵌入了自然时间多元化属性:投资组合收入和预期财富。尽管股票收入具有长期增长潜力,未来几年债券收益率有望提高,但我们仍然发现,对倾向于有机投资组合收入的投资者来说,对债券进行有意义的配置可能是最佳的。

Asset allocation should rely on a sound theoretical foundation that is empirically valid and robust in practice. Intertemporal CAPM (ICAPM) portfolio theory resembles the hedging/return-seeking portfolios approach sometimes used in practice, but with a sound theoretical foundation, empirical support, and attractive features for functional implementation. ICAPM portfolio theory largely resolves key issues with modern portfolio theory and standard CAPM portfolio theory, while providing a unified framework for liability-relative, goals-based, and asset-only asset allocation. The author documents the application of ICAPM portfolio theory to practice, addressing key implementation and technical issues related to the liability hedge, risky-asset portfolio optimization and constraints, portfolio selection and Monte Carlo simulation, and extensions to goals-based and asset-only asset allocation.
资产配置必须有一个经验有效、实践稳健的理论基础。跨期CAPM (ICAPM)投资组合理论类似于有时在实践中使用的套期保值/寻求回报的投资组合方法,但具有良好的理论基础、经验支持和功能实现的吸引力特征。ICAPM投资组合理论在很大程度上解决了现代投资组合理论和标准CAPM投资组合理论的关键问题,同时为负债相关、目标为基础、纯资产的资产配置提供了统一的框架。作者记录了ICAPM投资组合理论在实践中的应用,解决了与负债对冲、风险资产组合优化和约束、投资组合选择和蒙特卡洛模拟以及扩展到基于目标和仅资产的资产配置相关的关键实施和技术问题。

Relative performance of value with respect to growth has been a subject of industry debate for many years and is a cornerstone of numerous equity allocation decisions. This article presents a framework for quantifying the extent of over or undervaluation of value relative to growth and for identifying the key factors driving performance. The authors construct a fair value measure of the value factor to growth factor price-to-book ratio using prior-period ratio of price/book, 10-year trailing inflation, 10-year real Treasury yield, equity volatility, and growth of corporate profits in a vector error-correction model (VECM). This is then extended to a robust forecasting model for future value and growth returns. Upon conducting an out-of-sample value versus growth historical return forecast, the authors conclude that this method is a significant improvement over the use of historical average as a future return estimation. This methodology offers an alternative robust solution to forecasting value versus growth returns that can be further applied to asset allocation decisions and risk management.
价值相对于增长的相对表现多年来一直是行业争论的主题,也是许多股权配置决策的基石。本文提出了一个框架,用于量化价值相对于增长的高估或低估程度,并确定驱动业绩的关键因素。作者使用向量误差校正模型(VECM)中的前期价格/账面比率、10年期滞后通货膨胀、10年实际国债收益率、股票波动率和企业利润增长,构建了价值因素与增长因素价格账面比率的公允价值衡量。然后将其扩展为未来价值和增长回报的稳健预测模型。在进行样本外价值与增长的历史回报预测后,作者得出结论,与使用历史平均值作为未来回报估计相比,该方法是一个显著的改进。该方法为预测价值与增长回报提供了另一种稳健的解决方案,可进一步应用于资产配置决策和风险管理。

Market conditions change over the course of the business cycle. When are investors compensated to take risk? And what type of risk? This article proposes a practical regime-based framework for tactical asset allocation (TAA), combining leading economic indicators and global risk appetite to identify four macro regimes: recovery, expansion, slowdown, and contraction. The authors document distinct performance characteristics across regimes for traditional asset classes and their underlying risk factors, focusing on the term premium, credit premium, and equity premium. They provide simple and practical examples of TAA strategies for long-only multi-asset and fixed-income portfolios with the potential to generate attractive excess returns. Results are statistically significant and economically relevant after transaction costs, with information ratios between 0.70 and 0.80.
市场状况随着商业周期的变化而变化。什么时候投资者承担风险会得到补偿?什么类型的风险?本文提出了一个实用的基于制度的战术资产配置框架(TAA),结合领先的经济指标和全球风险偏好来确定四种宏观制度:复苏、扩张、放缓和收缩。作者记录了传统资产类别及其潜在风险因素在不同制度下的不同表现特征,重点关注期限溢价、信贷溢价和股权溢价。它们为只做多的多资产和固定收益投资组合提供了简单而实用的TAA策略例子,这些投资组合有可能产生有吸引力的超额回报。扣除交易成本后,结果具有统计学意义和经济相关性,信息比在0.70和0.80之间。

Several hidden risks of factor investing can lead to investor disappointment; even diversified baskets of factors are prone to sharp drawdowns and prolonged periods of underperformance. Accordingly, the authors explore a variety of techniques to improve the risk-adjusted returns of individual factors and factor portfolios. Introducing a new two-step volatility management method that adjusts the length of the estimation window to scale factor returns, the authors find that this technique is effective in improving both risk-adjusted returns and the trade-off between performance improvement and turnover characteristics. Ultimately, coupling this novel two-step approach with an optimization technique that captures both volatility and correlation information leads to improved risk-adjusted performance, lower volatility of volatility, and improved kurtosis and drawdown characteristics.
因子投资的几个隐患会导致投资者失望;即使是多样化的投资组合也容易出现大幅下跌和长期表现不佳的情况。因此,作者探索了各种技术来提高单个因素和因素组合的风险调整收益。引入了一种新的两步波动率管理方法,该方法根据比例因子收益调整估计窗口的长度,作者发现该技术在改善风险调整收益和绩效改进与周转特征之间的权衡方面都是有效的。最终,将这种新颖的两步方法与捕获波动性和相关信息的优化技术相结合,可以改善风险调整性能,降低波动性的波动性,并改善峰度和下降特性。

Putting the Long Term to Work: Shaping the Prudent Society Investment Model 把长期的工作:塑造审慎的社会投资模式

Thinking small is the last thing institutional investors should be doing right now. A fundamentally new investment model, best described as the Prudent Society Model, is emerging to cope with the changes, risks, and opportunities resulting from the sustainability transition. Institutional investors who are the first to succeed in getting this model right will flourish. The model integrates three insights: focusing on short-term disruption for long-term success, developing tools to successfully exploit new instruments and unlock new markets because of climate change, and deepening the ownership of investments. The authors suggest that boards need to learn, adapt, and experiment to implement this model.
机构投资者现在最不应该做的事就是考虑小问题。一种全新的投资模式,最好被描述为审慎社会模式,正在出现,以应对可持续性转型带来的变化、风险和机遇。最先成功将这一模式落实到位的机构投资者将蓬勃发展。该模型融合了三个见解:专注于短期破坏以获得长期成功,开发工具以成功开发新工具并因气候变化而打开新市场,以及深化投资所有权。作者建议董事会需要学习、调整和实验来实现这个模型。

Factor investing has been around for several decades, backed by an enormous body of literature, and yet it is still surrounded by much confusion and debate. Some of the rhetoric and myths have existed for a long time, while others have arisen in response to the difficult performance from 2018 to 2020 and the subsequent turnaround. This article examines many claims about factor investing; some are timeless, while others are focused on specific concerns that have emerged recently. The authors reference an extensive academic literature and perform simple, yet powerful, analysis to address these claims.
要素投资已经存在了几十年,有大量的文献支持,但它仍然被许多困惑和争论所包围。一些花言巧语和神话已经存在很长时间了,而另一些则是为了应对2018年至2020年的艰难表现和随后的转机而出现的。本文考察了许多关于要素投资的主张;有些是永恒的,而另一些则专注于最近出现的具体问题。作者参考了大量的学术文献,并进行了简单而有力的分析来解决这些问题。

Forecasting Stock Market Volatility 预测股市波动

Volatility as a measure of investment risk is widely accepted by academic researchers and industry professionals and has become ubiquitous in investment analysis. Furthermore, it is among the few financial variables that exhibit predictable time variation. Hence, there is an extensive amount of literature describing volatility models and assessing their forecasting power. This article provides a discussion of the prominent models and compares them in a unified notation framework. The empirical analysis shows that it is hard to outperform even simple trailing variance–type models. Autoregressive conditional heteroskedasticity (ARCH), generalized ARCH (GARCH), implied volatility, asymmetric, and seasonal models hardly improve forecasts despite added complexity. In this study, only momentum-based and intraday data–based models improved predictive accuracy significantly.
波动性作为一种衡量投资风险的指标被学术研究人员和行业专业人士广泛接受,并在投资分析中无处不在。此外,它是少数几个表现出可预测时间变化的金融变量之一。因此,有大量的文献描述波动率模型并评估其预测能力。本文对突出的模型进行了讨论,并在统一的表示法框架中对它们进行了比较。实证分析表明,即使是简单的尾随方差型模型也很难超越它。自回归条件异方差(ARCH)、广义ARCH(GARCH)、隐含波动性、不对称和季节性模型尽管增加了复杂性,但几乎无法改善预测。在这项研究中,只有基于动量和盘中数据的模型显著提高了预测准确性。

The Death of Active Management Has Been Greatly Exaggerated 主动管理的死亡被过分夸大了

Over the past decade, the asset management industry witnessed a significant migration of capital from active investment strategies into passive investment strategies. Undoubtedly, the structural change is shaking the active management–dominated mutual fund industry to its core. A closer scrutiny of active management suggests that the performance of active managers is mainly a function of both stock selection and portfolio construction. As other studies have already provided evidence of successful stock selection strategies via factor premiums, the author focuses on examining the impact of portfolio construction on portfolio performance. The author finds that active managers’ failure to incorporate risk during portfolio construction overwhelms the expected return signal from stock selection.
在过去的十年里,资产管理行业见证了资本从主动投资策略向被动投资策略的显著迁移。毫无疑问,这种结构性变化正在彻底动摇以主动管理型基金为主的共同基金行业。对主动管理的仔细研究表明,主动经理的业绩主要是股票选择和投资组合构建的功能。由于其他研究已经通过因素溢价提供了成功的选股策略的证据,因此本文将重点研究投资组合结构对投资组合绩效的影响。笔者发现,主动型经理人在投资组合构建过程中未能将风险纳入其中,这使得选股的预期收益信号无法得到体现。
