What are the research questions To most readers, it’s no surprise that our ears perk up a little bit anytime someone attempts to broaden the understanding of the value anomaly. The precise reason why high book to market equities have higher expected returns has been a long-standing debate among

What are the research questions? Institutional Investors are increasingly allocating to multi-asset strategies (p.17 ) as they seek to access greater diversity, liquidity, and reduced volatility (survey results from Greenwich Associates, 2015). The main research questions of the paper are as

What are the research questions? This research focuses on the relationship between the frequency of unexpected short selling behavior and abnormal returns surrounding credit watch and rating change announcements in the equity market. It is notable that it employs a unique database that affords the

Similar to some better-known factors like size and value, time-series momentum is a factor which has historically demonstrated above-average excess returns. Time-series momentum, also called trend momentum or trend-following, is measured by a portfolio which is long assets which have had recent

What are the research questions? Despite Peter Bernstein’s suggestion in 2003 that adherence to a fixed and undiversified policy portfolio is dangerous, benchmarks ( the most used of which is the 60/40) are as popular today as they were 15 years ago. The authors study the following research

Smart beta (or factor investing) seems to be the product du jour in ETFs. There are so many different factor products available that just about every fund company seems to offer them…even Vanguard is launching their own suite of factor-based stock funds. Note that nearly all of these products are

What are the research questions? Financial theory asserts a clear link between the risk-free interest rate and the pricing of equity securities, regardless of the time horizon. Therefore, the market’s opinion about the uncertainty of rates should improve models forecasting equity volatility in the

Merger arbitrage, sometimes known as “risk arbitrage,” is an investing strategy in which the investor bets on announced M&A deals. After a merger is announced, shares of the target tend to trade below the offered price (due to deal uncertainty), representing the arbitrage spread; if the deal

Wes asked that I contribute to the ongoing debates regarding the construction of value and momentum portfolios. There are three key research pieces on the topic, all with different viewpoints: Alpha Architect’s take AQR’s take Newfound Research’s Take I encourage everyone to dig into the three

J.P. Morgan researchers, Marko Kolanovic and Zhen Wei, produced an incredibly detailed report on all aspects of momentum (one of our favorite topics!) Here is a link to the report 188 pages of pure effort and information. Here is a summary of what is examined in the research: As the virtually

What are the research questions? According to Datamonitor (2010), the influence of peer-based advice, such as user-generated ratings on Amazon.com or Yelp.com, is increasing while traditional advice (e.g., from Consumer Reports or the Michelin guide) is decreasing. This trend is starting to emerge

It has been well-documented that value stocks have provided higher expected returns than growth stocks. However, there is a great debate about the source of that premium: Is it risk-based or is it related to behavioral errors that create persistent mispricings? There are many papers presenting

What are the research questions? Is the rate of turnover for outside directors unusually high either before fraud is discovered by the firm, or during its commission? Are there regularities in the characteristics of outside directors who depart during the period in which the financial fraud is

It is that time of year again, the American Finance Association Annual Meeting is underway. The conference is in Philadelphia, starting today (January 5) and running through Sunday (January 7). This 3-day conference has 73 sessions, 246 papers and 12 presentations with no papers (general

A few weeks ago, we did a deep dive into the factors versus characteristics debate. One of the reasons we’ve brought up this debate is due to the fact that “factor” loadings (from regressions) are arguably not as helpful as portfolio characteristics. In other words, knowing a portfolio P/E

Conventional wisdom can be defined as ideas that are so accepted that they go unquestioned. Unfortunately, conventional wisdom is often wrong. Two great examples are that millions of people once believed the conventional wisdom that the Earth is flat, and millions also believed that the Earth is the

What are the research questions? Given the prevalence of buybacks as a form of corporate payouts, should they be explicitly included in supply-side models such as the dividend discount model (DDM) used to forecast of stock returns? Does the same superior performance extend to the prediction of

There has been much discussion of the small-cap premium recently. Has its popularity cannibalized its utility? Are large firms preventing a level playing field? Will the small-cap premium exist going forward? This article does not address these concerns directly, but it does identify and analyze

The academic research has generally found valuations, such as the earnings yield (E/P) (or the CAPE 10 earnings yield) and valuation spreads, have predictive value in terms of future returns. The higher the earnings yield, the higher the expected return, and the larger the spread in valuations

Trend-following is something I’ve struggled with for years — always felt like voodoo magic and data-mining. That said, I finally came around to appreciating the practice after a ton of research replication efforts, independent research. At the time I was investigating the topic there really

Does the industry concentration exhibited in short sellers’ holdings convey new material information about the industry? Are the excess returns obtained from industry shorting combined with firm-specific shorting strategies explained by risk? Is the industry shorting signal correlated with

Here is a link to our recent podcast on Behind the Uniform. I’m so humbled and honored to have Wesley Gray on the show today, talking about his experience building Alpha Architect. I found Wes through a Wall Street Journal article that starts with: “Wesley Gray’s value-focused fund of overseas

What are the research questions? What are the general circumstances associated with independent director departures? Is it possible to identify situations whereby the departure is unexpected and not due to retirements, director outside commitments or firings by the firm? Are the unexpected or

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. Initial research on momentum was published by Narasimhan Jegadeesh and Sheridan Titman, authors of the 1993 study,

Much has been made of Factor Investing, and even Vanguard is launching a suite of actively-managed factor ETFs. But even now, with Vanguard offering factor ETFs, there are many investors that only invest passively into an index fund, such as the SP500 or EAFE index. These investors will cite the

Many investors, investment professionals, and pundits make comments regarding the relationship between stock correlations and opportunities for active stock pickers. For example, here is a recent example from the Financial Times: Correlation crash clears way for stockpickers. The basic (albeit

Factor investing, and the associated intellectual battles, have raged for decades in academic finance journals. However, now that factor investing has gone mainstream via ETFs, the debate has broader interest among the investing public. Some investors question the very existence of factor premiums.

On most mainstream finance websites, a good chunk of the stories discuss the FED and where interest rates are going. Intuitively, this makes sense: The FED is arguably an extremely influential component of U.S. economy. But how do markets respond to the FED? Is the response rational, irrational, or

The subject of asset bubbles and market crashes has fascinated me for more than 20 years. As an options market maker for Susquehanna International Group (“SIG”), extreme price movements were a daily source of concern. I sat next to Jeff Yass for years and watched him manage option positions in

Regression analysis is used all the time to assess how a portfolio “loads” on certain factors. The most common factor loadings examined are the market, size, value, and momentum factors. This can be an informative exercise, and there are nice tools online, such as portfolio visualizer, which

Changes in earnings are comprised of the expected earnings number plus any seasonal component of earnings. If the seasonal component is expected then it should not affect prices in an efficient market. However, unusual returns have been documented surrounding earnings announcements at the seasonal

This article examines a somewhat over-looked, but important, discussion that raged among academic researchers in the late 1990’s and early 2000’s. The topic: factors versus characteristics. What do you mean, “Factors versus characteristics?” We often highlight that the value premium can be

In this study, a two-factor risk model is developed assuming differing preferences for “sin” or “no-sin” stocks for two groups of investors. Social screens are built into the model by assuming a small percentage of investors are self-restricting, declining to invest in “sin” stocks.

Replicating Anomalies is arguably a “must read” for anyone who thinks about factor investing and is looking to improve their understanding of the space. Lu Zhang, and his colleagues, Kewei Hou and Chen Xue, spent nearly 3 years carefully compiling and replicating 447 “anomalies” identified

Wes recently challenged me with a unique proposition: Hey Ryan, read through this Replicating Anomalies paper and tell me what you think. Its a bit long, but I’m curious to hear your thoughts. Well, by “a bit long,” Wes really meant 144 pages of equations and reams of quantitative data on

When performing multiple-based valuations, which rely on the assumption that perfect substitutes should sell for the same price, it is very important to identify companies that are truly comparable. Most analysts use industry classifications. Lee et al. (2015) note that industry classifications are

Trend-following strategies have historically been laughed at via the modern academic finance research community. Having first-hand knowledge of that community, we can verify that academic researchers are humans like the rest of us (we checked, academics aren’t robots), and they suffer from group

What are the research questions? Based on the evidence that tweets are faster than news in revealing new market information, but that news is regarded a more reliable source of information, the authors propose a superior trading strategy based on the sentiment feedback strength between the news and

Academic research is amazing and incredibly useful for helping us better understand the complex world in which we live. In fact, academic research has literally rewired my brain at times. However, research isn’t perfect and the search for truth is messy. Data-mining. Overfitting. P-hacking.

One area in investing that is often overlooked by investors is trade execution, which relates primarily to commissions, bid-ask spreads, and price impact. Yet sometimes it is trade-execution alone that can make the difference between and profitable trade and an unprofitable one. In a new paper,
