The carry factor is the tendency for higher-yielding assets to provide higher returns than lower-yielding assets — it is a cousin to the value factor, which is the tendency for relatively cheap assets to outperform relatively expensive ones. A simplified description of carry is the return an

It ain’t what you don’t know that gets you into trouble. It’s what you know for sure that just ain’t so. — attributed to Mark Twain. Mark Twain had some great insights. The quote above can apply to just about every aspect of life, including investing. This axiom is particularly relevant

As everyone who’s been invested for the last ten years knows, post-financial crisis stock returns have been incredible. The chart below highlights the total returns for the S&P 500 Index, the MSCI EAFE Index, the MSCI EEM Index, and the MSCI ACWI Index. The results are hypothetical results and

Coined by Rosenthal in 1979, the term file drawer problem refers to the notion that journal editors are biased toward accepting articles that include statistically significant results over those with nonsignificant results. The competition for increasing the citation count and improving journal

Factor investing research has a long storied past. Fama and French’s 1992 and 1993 papers arguably put factor investing “on the map,” but truth be told, factor investing is an old topic with roots grounded in the so-called arbitrage pricing theory. We have a longer piece on the history of

What are the research questions The presence of historical prices impacting future returns, i.e., momentum, has been well researched in the equity market, which we’ve covered here. We’ve also closely looked at momentum in bond markets here, here, and here. What the Bali, Subrahmanyam, & Wen

This is an important article for practitioners because it brings specific investing decisions that are often treated as afterthoughts, to the forefront in style-based investing. The authors propose that decisions made beyond the initial decision to invest in a style, such as value or momentum, are

One of the big problems for the first formal asset pricing model developed by financial economists, the Capital Asset Pricing Model (CAPM), was that it predicts a positive relationship between risk and return. However, the historical evidence demonstrates that, while the slope of the security market

What causes a stock’s price to move? A great question, and one that puzzles most market observers every day. Since this is puzzling, it is an entertaining topic to discuss–enter CNBC and the financial media. In the short-run, stocks prices can move for a variety of reasons … noise trading,

The paper investigates the following research question: Can machines allocate capital in the classic style of a value investor like Benjamin Graham or Warren Buffett? What are the Academic Insights? By connecting two broad and disparate areas (the innovative AI domain and the more old-fashioned

What are the research questions? Using eVestment, a source of data for asset managers, the authors evaluate U.S. fundamental and quantitative managers, specifically core, growth and value styles. Eighteen strategy types (six in each style) were identified and results calculated using averages for

Here is a link to our podcast on Flirting with Models. Today I am speaking with Jack Vogel, co-CIO of boutique ETF issuer Alpha Architect. I’ve known Jack for some time now and was particularly excited to bring him on the show for two reasons. The first, which you will quickly learn in the

The superior performance of low-beta and low-volatility stocks was documented in the literature back in the 1970s — by Fischer Black (in 1972) among others — even before the size and value premiums were “discovered.” The low-beta/low-volatility anomaly has been demonstrated to exist in

Farre-Mensa and Ljungqvist (2016) observe that many measures of financial constraints used in the literature are flawed. In fact, to date, it remains an empirical challenge to quantify them. The authors attempt at solving this problem by answering the following research questions: Can textual

As a native Philadelphian and huge basketball fan, I fully agree with the 76ers fan’s rally cry — Trust the Process. Even the players, such as Joel Embiid, have echoed the sentiment of the fans: For those not in Philly and not too familiar with the NBA, “Trust the Process” explains the 76ers

What are the research questions? The authors propose and test an enhanced Shiller model that incorporates macroeconomic conditions, by modeling real bond yields and volatility, equity volatility and inflation, in a 2 step approach to forecasting equity returns. The underlying thesis is that the

In the past, we have examined the following two topics: (1) stock performance & the 52-week high and (2) the investment CAPM. When examining the performance of stocks relative to their respective 52-week high (highlighted by us here), the authors (George and Hwang) find the following: When

The paper investigates this issue by answering the following research questions: Are commodities returns positive on average? How do they vary in different economic states (backwardation/contango; expansion/recession periods; unexpected inflation) ? How have they contributed to a broad portfolio?

We believe there are cause and effect relationships in the world — and in investing — that hold true over time. Many are common sense and easily observable – like fire creates smoke – while others are harder to see and understand. With factor investing, true relationships can be hard to see

Recently, Wes pointed me to this interesting paper by David Rapach, Jack Strauss, Jun Tu and Guofu Zhou: “Dynamic Return Dependencies Across Industries: A Machine Learning Approach.” The paper presents a strategy that forecasts industry returns and shows excellent historical returns. In this

What are the research questions? Does the Fama-French “size” factor explain the cross-section of stock returns in the Chinese A-share market? Does the Fama-French “value” factor explain the cross-section of stock returns in the Chinese A-share market? What are the Academic Insights? YES. The

Factor Regressions are one way to ascertain a fund’s exposure to certain factors that an investor/advisor may want to allocate towards, such as Value, Momentum, Quality, etc. Luckily, there are some great free tools available online, such as portfoliovisualizer.com, that allows investors to run

For many investors, the superiority of passive investing over active investing is axiomatic (Earth to passive investors; Lunch is never free!) And why not? Study after study has demonstrated that only a small portion of actively managed funds beat their benchmarks over long time frames. A recent

The paper investigates this issue by answering the following research questions: Can common robust risk premia (value, momentum, carry and defensive) enhance returns in Fixed Income investing? Do style-based Fixed Income portfolios present diversifying potential? Is a long/short implementation

One of the big problems for the first formal asset pricing model developed by financial economists, the Capital Asset Pricing Model (CAPM), was that it predicts a positive relationship between risk and return. However, the historical evidence demonstrates that while the slope of the security market

Assume you made a decision to invest in an active strategy based on, say, a backtest of the underlying process (to be clear, active means NOT passive market-cap weight in my context). Over the next few years, you sit in the strategy watching it underperform the passive benchmark. You are a

The authors conduct a comprehensive analysis of five categories of technical trading rules (including channel break rules, filter rules, moving average rules, oscillator rules and support/resistance rules) using aggregate data from the Chinese stock market for the period 1997 to 2015. Do technical

The Capital Asset Pricing Model (CAPM) indicates returns should go up linearly as beta increases (in other words, risk and return are positively related). However, as I’ve previously discussed, the historical evidence demonstrates that, while the slope of the security market line is generally

This year’s annual financial research “geekfest,” officially known as the American Finance Association Annual Meeting, assembles the world’s top-tier academic researchers to discuss their latest financial research. Source: Wes’s art studio and a photo by Daniel Cheung If you are looking to

Mirror, mirror, on the wall – which is the fairest of them all? Recent commentary (to include a recent Barron’s article) seems to suggest that value is dead and may never come back. Of course, most of these comments revolve around the price-to-book valuation metric, which, as the Barron’s

The authors discuss a variety of past research papers on time-series momentum but pay particular attention to the Moskowitz, Ooi, and Pedersen (“MOP”) 2012 JFE paper, “Time Series Momentum.” This paper is arguably the first paper in recent memory to crack the top-tier academic journals with

There are now hundreds of factors in what John Cochrane famously called the “zoo of factors.” However, there are only a small number that meet the requirements for investment that my co-author, Andrew Berkin, and I establish in our book, “Your Complete Guide to Factor-Based Investing”:

As evidenced by the image below, interest in momentum research has taken off since the original 1993 Jegadeesh and Titman paper: Source: “Two Centuries of Multi-Asset Momentum (Equities, Bonds, Currencies, Commodities, Sectors and Stocks)”

Yield. Within almost any asset class, investors want to know, what is the “yield” on the investment? For some investors, this is the most important and only screen used when sorting funds. Mutual fund companies have found ways to feed the beast by “juicing” the dividend yield on equity

A growing number of investors are seeking to construct portfolios that simultaneously capture the 1) long-term factor premia ( value, momentum, size etc.) and 2) have attractive ESG profiles. The main research questions of the paper are as follows: Is the relationship between ESG and factor stable

How will systematic (“coordinated”) investing affect prices? What is the risk of increasingly coordinated holdings (crowding)? How does coordinated investing affect market microstructure and optimal execution? Is factor timing possible? What are the issues in the design of factor-based

This article proposes tail risk hedging (TRH) as an alternative model for managing risk in investment portfolios. The standard risk management approach involves a significant allocation to hiqh-quality bonds. However, this approach has historically reduced expected returns over the long term (see

Buy cheap. This is a motto many live by, not only in their daily lives but also in their investment philosophy. Historically, “buying cheap” stocks was a good idea (i.e., the so-called “value” premium). But how might valuation matter when it comes to country allocations? In other words,

What are the research questions? By studying tweets on thirty companies in the Dow Jones Index, the authors ask the following research question: Is it possible to develop a system for the detection and discovery of the popularity of special events on Twitter that may influence the financial markets?

Most of the literature on the momentum factor has focused on behavioral explanations, generally either investor underreaction or overreaction. For example, in his paper “Explanations for the Momentum Premium,” Yale University professor Tobias Moskowitz points out: Underreaction results from

Momentum is the tendency for assets that have performed well (poorly) in the recent past to continue to perform well (poorly) in the future, at least for a short period of time. In 1997, Mark Carhart, in his study, “On Persistence in Mutual Fund Performance,” was the first to use momentum,

Recently there has been a fairly active discussion within the financial media on the topic of stock buybacks, or share repurchases. This is probably due to the recent tax reform, which has caused many to question where companies will spend their additional profits now that firms (on average) will be

When stock prices reach a new high, investors start asking the question: Are stocks overvalued? To answer this question, investors have developed several alternative equity valuation models. Typically, each of this models compares the stock market’s current price level to a benchmark. Among

Readers often send us great questions related to different ideas on systematic value strategies. The outcome of years of back and forth with readers and internal discussions is several books and hundreds of blog posts on the subject of value investing. So…What have we learned? We’ve learned a

Are there variations in the methods that funds use to manage risk? Do hedge funds practicing risk management outperform other funds during periods of financial crisis? Are there differences in the type of risk management practices in terms of performance? Are there competing explanations that may

High net worth individuals, university endowments, and public pension funds have heavily invested in long/short equity hedge funds. But is the long/short equity asset class benefiting investors? The pitfalls of expensive financial products are well documented in the academic literature; however, the

The literature shows that macroeconomic factors can drive asset returns, however, economists and investment teams operate independently. In this paper, the authors attempt to bring macroeconomic discipline to tactical asset allocation by highlighting macroeconomic “dashboards:” The authors

What are the research questions? This study uses a new classification system for informed vs. uninformed retail trades: short selling stocks without options available indicates more informed trading than short selling stocks with options available. Is there a difference in returns between shorted

Factor investing promises outperformance at low cost. But to add value in a portfolio, it must deliver positive risk-adjusted returns and with low correlation to existing holdings. Historically, pure factor exposures have earned similar risk-adjusted returns to buying and holding plain vanilla asset
