Cliff Asness was facing a dilemma into how he would plunge his hedge fund into the hottest investment area worldwide - ESG Investing. Founder and managing principal of AQR - one the most storied quantitative hedge funds in the world - Asness knew anything less than a big splash was not an option. To this end, Asness was planning to launch a liquid equity long-short fund he hoped would appeal to ESG sensitive clients. Shorting was unheard of in the ESG space, but Asness knew that it could send a new, and powerful message, on carbon neutrality - and ESG weighting more broadly - that he hoped ESG investors were ready to send. He would soon find out just that...
This note explores the selection of investment managers and the performance-measurement tools associated with this important task. In selecting investment options for a firm's 401(k) plan, identifying possible managers to oversee a portion of an endowment's or foundation's investment portfolio, or a retail investor's decision of which fund to choose for their regular investment account, investment performance is likely to play an important role. In this technical note, we explore a number of different performance measures that may be used to select managers, including total return, alpha, and information ratio, and a key risk measurement used in this approach, tracking error.
This case explores the dynamic allocation approach to investing, an approach that would time the market based on factors' relative valuations. Research Affiliates created a RAFI Dynamic Multifactor US index that dynamically allocated five factor strategies: value, quality, momentum, size, and low volatility. In this course, students will utilize various information presented in the case to discuss why Research Affiliates decided to launch the strategy, how Research Affiliates times it, and what has been its performance relative to the Russell 1000 Index and other competitors. Students will also assess the strategy's performance and some of the limitations of its dynamic strategy.
Using the context of a private-bank chief economist preparing for a client call just as the Shanghai Stock Exchange Composite Index (SCI) reached a 29-month high on July 7, 2020, this case places students in a position to prepare an outlook on the prospects for investment in China. It also enables the comparison of China to various potential investment geographies, such as the United States and other financial markets around the globe. The material covers the development of China's financial system from the 1980s to the 2020s, paying particular attention to the banking system, equity and debt markets, and the structure of household-level financial assets. Special emphasis is placed on the most recent boom-and-bust cycles of Chinese equities, helping students to understand the factors suggesting additional equity growth and retraction. The case applies Robert Shiller's standard analysis for speculative bubbles to China's equity market. China is the world's second-largest economy and equity market, but its stock market is still underdeveloped relative to other investment channels, as evidenced in the structure of China's aggregate financial assets and the composition of household wealth. Additionally, the government response and interventions play a large role. How would COVID-19 affect the investment opportunities in China, and how did China's markets compare to markets in the rest of the world? Most importantly, was this the time for American investors to invest in China? This case has been taught in a second-year MBA elective on China in the global economy, in a module examining progress and challenges in Chinese markets. It has also been successfully taught in a course on emerging markets, in a module examining global investments. The material allows for an examination of financial markets in China in particular, and stock market conditions in emerging markets more generally.
This case examines the role of beta and volatility in assessing the risk of a portfolio. Students assume the role of a fund manager who is adjusting their portfolio in response to the 2014 reconstitution of the fund's benchmark-the Russell 2000 index. The manager chooses between two stocks recently added to the index (and correspondingly to the manager's investment universe): First Citizens Bancshares, Incorporated, and Innoviva, Inc. Under the assumption that the manager's assessment of the future performance of both stocks is similar, students have to determine which stock will increase the risk of the portfolio more. Students are tasked with calculating the beta and standard deviation for the stocks individually and as part of the manager's portfolio, and then choosing which stock to add to the portfolio. The case also introduces the concepts of benchmarking and the construction and rebalancing of market indices.
The case explores the momentum investment strategy of AlphaArchitect, a boutique asset management firm. The protagonist, Wes Grey the CEO of AlphaArchitect, is preparing a potential client presentation for Lochen Capital, a multi-family office. Lochen has traditionally focused on value-investing and as a result the presentation needs to compare and contrast the two styles. The case introduces students to the simplest of quantitative investing strategies, momentum. Additionally, students explore AlphaArchitect's approach to implementing the theoretical momentum strategy in practice through their ETF product.
The case examines the short selling of GameStop by hedge fund Citron Capital. The valuation case for short selling GameStop is explored, along with the actual market mechanics of short selling a stock (i.e., rebate rates, securities lending collateral, and loan recalls). In addition to the costs, additional risks of short selling, including the potential for a short squeeze, are introduced.
In this technical note, we examine the concept of diversification and the tradeoff between risk and return in portfolio theory. The note includes a general introduction to normal distribution, then applies it to portfolio theory by examining normal distribution of future return and risk. The note also examines formulas for calculating expected returns of various two-asset portfolios and applies these formulas to investment decision-making. Finally, it touches on errors of inference, including survivorship bias and statistical concerns around skewness or excess kurtosis.
This case uses the California Public Employees' Retirement System (CalPERS) to set the stage for unfolding an analysis of economics and values in the decision to divest tobacco stocks and bonds from the internally managed portion of the CalPERS portfolio. Written from public sources, it offers a discussion about fiduciary responsibility for long-term retirement security and investment policies around environmental, social, and governance (ESG) strategies for the public pension fund. The material includes financial data that further allows calculations and discussion on tobacco investments outperforming the broader market. This A case opens with the CalPERS investment committee having made a decision to recommend removing tobacco investment restrictions. The CIO reflects on whether supporting investment in tobacco firms conflicts with CalPERS's member health and health care mission. Did supporting continued divestment mean CalPERS was putting its own social priority and ideals ahead of its clients' investment goals? The case data should lead most to conclude the fund was breaching its fiduciary duty.

Did supporting continued divestment mean CalPERS was putting its own social priority and ideals ahead of its clients' investment goals? The case data should lead most to conclude the fund was breaching its fiduciary duty. This short B case can be handed out in class. This deepens discussion around ESG, the investment fund's duty, and retirees' frustration. Despite the CalPERS investment committee's recommendation to remove restrictions on investing in tobacco stocks, the board of administration decided to broaden limitation and extend the ban to externally managed portfolios in December 2016. Two years later, opposition to CalPERS's divestment strategy took the form of a campaign to run for a seat on the board of administration. This was followed with the appointment of another CIO who strongly supported ESG investment strategies.
Due to an increase in the number of wealthy individuals the demand for artwork had increased, and artwork was considered an investment asset. Artwork was listed as a "treasure asset" or an "investment of passion" by investment industry publications, recognizing its importance in the portfolios of the wealthy. The financialization of the art market went hand in hand with a growing understanding of the investment properties of art. Developing this knowledge took time because measuring the returns to a heterogeneous and illiquid asset like art-or real estate-was challenging.
Identifying an appropriate benchmark is an essential step in assessing a manager's performance. In the prospectus or fund advertising materials, a benchmark for the fund is typically identified, and the performance of the fund relative to that benchmark is given. The issue of concern is whether or not the benchmark provided has a similar risk profile to the fund.
For many years, Towers Watson (TW) has conducted its own research into alternative approaches to market cap investing. Philip Tindall senior investment consultant with TW was impressed by a recent presentation by the CIO of Research Affiliates (RA) about an innovative investing concept called the "Fundamental Index methodology." He thinks it might be an important innovation in applying nonmarket cap approaches, but he has some concerns about the approach and whether or not it would be appropriate for TW clients. Clients depended on TW to keep them on the cutting edge of institutional investing, but recommending an untried investment strategy and deviating from status quo investment practice could either generate outperformance relative to their investment consulting competitors, thereby attracting new clients, or it could result in underperformance and defection of their clients to those competitors.
This case examines the importance of forecasting expected returns in asset allocation decisions. While the case is targeted to MBA students in an investments or portfolio management course, it is also appropriate for an advanced undergraduate course. It is written from the perspective of a new employee at a small investment management firm that was surprised by the market crash of 2008 and subsequent market rebound in 2009. The CIO of the firm is meeting with an important client to explain his asset allocation recommendations for 2008 and 2009 and to suggest a new allocation going forward. He enlists the help of this new employee in preparing the materials for this presentation. The case requires students to analyze the ability of simple valuation ratios to forecast returns. Students will use a smoothed price-to-earnings ratio to forecast future returns and given step-by-step instructions for the analysis. In addition, students must use their regression results to form a simple (two-asset) tactical asset allocation strategy to better understand the importance of forecasting expected returns for asset allocation decisions and how such forecasts could be used to form a simple tactical asset allocation model. Students also will examine the issues associated with performance measurement for a tactical asset allocation or market-timing investment strategy.
This technical note provides a simple, yet powerful, optimization exercise to demonstrate the benefits of diversification in a portfolio and the importance of asset allocation. While the note is targeted for MBA students in an investments or portfolio management course, it is also appropriate for an advanced undergraduate course.
This case examines the importance of liquidity to financial markets, using the dramatic volatility of mutual fund flows in 2008 as an example. While the case is targeted to MBA students in an investments or portfolio management course, it is also appropriate for an advanced undergraduate course. It is written from the perspective of a fund manager who has experienced significant redemptions in 2008 and is considering whether or not to use ReFlow Management LLC's "liquidity provision" service. The case requires students to examine the nature and magnitude of mutual fund trading costs, how fund flows may induce additional trading and how ReFlow's innovative service attempts to resolve these issues. Through this analysis, students will better understand what is meant by the term "liquidity" and how liquidity, or a lack thereof, can negatively impact portfolio performance.
The owner of a small financial services firm is evaluating the performance of four funds to determine whether to offer them to his clients. The funds span a variety of objectives and include a recently initiated fund. The case explores issues related to the evaluation of mutual fund performance, including the selection of benchmarks and the effect of fees. The case provides a natural and compelling context in which to discuss market efficiency.
