This paper examines the changes in asset correlation over time to better understand the application of Portfolio Theory in the modern era. The goal of the provided research is to provide evidence that asset correlations have changed over time, not only across equities, but across fixed income securities and commodities as well. As a result of these changes, investors can make more educated decisions based on personal risk tolerances, ability to decrease portfolio variance, and investment goals. Assets classes are selected across bonds, commodities, and equities with different characteristics, such as geography, industry exposure, and purpose. Correlation is calculated for four periods of five years beginning in 2001, utilizing monthly returns. Overall, assets classes have been increasing in correlation over time, with the assets selected averaging a 2.68% increase in correlation in each period of five years. On average, equities increased the most, with correlation increasing 9.69% on average across each period of five years, with bonds decreasing in correlation on average by 4.25% for each period of five years, and commodities showing no significant changes in correlation. Between 2011 and 2016, each asset class saw the direction of correlation changes change, possibly due to drastically different foreign economic policies. The remainder of this paper serves as a case study of historical financial events throughout the past twenty years, which provide evidence to an increasingly globalized economy, which has caused more congruency in asset returns. In terms of crafting manageable strategies to average investors, it can be inferred that asset class diversification is a more effective means of lowering portfolio variance and spreading risk than investing in international equities.

This paper examines how the implied correlation between an ETF and its underlying assets changes through time and how an investor may take advantage of these changes. The goal of this research is to show that due to times of increased or decreased volatility or other market factors, the co-movement between an ETF and its underlying assets is not always perfectly correlated. This leads to an investment opportunity where, depending on the changes, the correlation between an ETF and its underlying assets is higher or lower compared to its historical average implied correlation. An ETF was selected which had twenty-four underlying assets and both the ETF and its assets have listed options. The implied volatility of the selected ETF and the implied volatilities of its underlying assets were utilized to calculate the implied correlation over a period of thirty-six months between 2017-2019. The results of this study show how implied correlation changed through time. The point where the selected ETF was most correlated with its underlying assets occurred on February 2, 2018 and the implied correlation was 91.12%. In addition, the point where the ETF was least correlated with its underlying assets occurred on September 1, 2017 and the implied correlation was 31.11%. Through this time period, the average implied correlation between the ETF and its underlying assets was 59.70%. Using this data, a correlation trading strategy was tested during a period of high implied correlation between the ETF and its underlying assets. On December 14, 2018, the implied correlation was 88.49% and the results found that an investor using this strategy could profit by $0.5002 per share. The remainder of this paper is organized into an analysis of the topics and related literature, followed by an analysis of the data and methodology, and finally the presentation of the results and summary.

The pattern of correlation between stocks and bonds has important implications for optimal cross-market asset allocation decisions, and risk management strategies by investors. Earlier empirical studies assumed a constant stock-bond correlation. An increasing number of recent studies however, are of the view that the relation exhibits substantial time-variation. This study explores the information in daily correlations, to ascertain the extent and pattern of timevariation with the aim of deriving evidence on time-variation over short periods. The empirical methodology involved statistical inference in conjunction with quantile analysis, using the rolling window sample correlation method. This methodology provides evidence on the statistical importance of the correlation changes, and also facilitates information on timevariation over short periods from the distribution of conditional daily correlations. The study found substantial changes in sizes and signs in the daily correlations. We conclude that there is substantial time-variation in the value of daily correlations. Specifically, the daily correlation changes and takes on high positive and negative values relative to a low historical value. The important implication of frequent change in the correlation is that the hedging benefits from asset portfolios allocated over stock and bonds is subject to frequent changes, as a result portfolio managers approach to evaluating and managing portfolio risk should be dynamic.

Generate solid, long-term profits with a portfolio allocated for your investing needs Asset allocation is the key to investing performance. Unfortunately, no single approach works perfectly—developing the right balance requires a clear-eyed look at the many models available to you, various investing methodologies, and your or your client’s level of risk tolerance. And that’s where this important guide comes in. Written by a leading allocation expert from T. Rowe Price, Beyond Diversification provides the knowledge, insights, and approaches you need to make the best allocation decisions for your goals. This deep dive into the how’s and why’s of asset allocation is organized by the three decisive components of a successfully allocated portfolio: Return Forecasting discusses the desired return investors seek. Risk Forecasting covers the level of risk investors are prepared to assume to achieve that return. Portfolio Construction calibrates the stock-bond mix that balances the risks and returns. With examples from T. Rowe Price’s asset allocation team showing you how the process works in the real world, Beyond Diversification provides everything you need to find the asset combination that will deliver the results you seek. You’ll learn how to choose the right tradeoffs, build the most effective asset allocation combination for your needs, and dramatically increase your odds of success for the long run.

Academic finance has had a remarkable impact on many financial services. Yet long-term investors have received curiously little guidance from academic financial economists. Mean-variance analysis, developed almost fifty years ago, has provided a basic paradigm for portfolio choice. This approach usefully emphasizes the ability of diversification to reduce risk, but it ignores several critically important factors. Most notably, the analysis is static; it assumes that investors care only about risks to wealth one period ahead. However, many investors—-both individuals and institutions such as charitable foundations or universities—-seek to finance a stream of consumption over a long lifetime. In addition, mean-variance analysis treats financial wealth in isolation from income. Long-term investors typically receive a stream of income and use it, along with financial wealth, to support their consumption. At the theoretical level, it is well understood that the solution to a long-term portfolio choice problem can be very different from the solution to a short-term problem. Long-term investors care about intertemporal shocks to investment opportunities and labor income as well as shocks to wealth itself, and they may use financial assets to hedge their intertemporal risks. This should be important in practice because there is a great deal of empirical evidence that investment opportunities—-both interest rates and risk premia on bonds and stocks—-vary through time. Yet this insight has had little influence on investment practice because it is hard to solve for optimal portfolios in intertemporal models. This book seeks to develop the intertemporal approach into an empirical paradigm that can compete with the standard mean-variance analysis. The book shows that long-term inflation-indexed bonds are the riskless asset for long-term investors, it explains the conditions under which stocks are safer assets for long-term than for short-term investors, and it shows how labor income influences portfolio choice. These results shed new light on the rules of thumb used by financial planners. The book explains recent advances in both analytical and numerical methods, and shows how they can be used to understand the portfolio choice problems of long-term investors.

Artificial intelligence (AI) has grown in presence in asset management and has revolutionized the sector in many ways. It has improved portfolio management, trading, and risk management practices by increasing efficiency, accuracy, and compliance. In particular, AI techniques help construct portfolios based on more accurate risk and return forecasts and more complex constraints. Trading algorithms use AI to devise novel trading signals and execute trades with lower transaction costs. AI also improves risk modeling and forecasting by generating insights from new data sources. Finally, robo-advisors owe a large part of their success to AI techniques. Yet the use of AI can also create new risks and challenges, such as those resulting from model opacity, complexity, and reliance on data integrity.
