There are several big academic finance conferences that attract the best research and the best researchers in one bullpen — the AFA and the WFA meetings. We chatted about the AFA event last January (be sure to check that out). But now it is the WFA’s turn. I attended the WFA a few years back in

A new paper, “Facts about Formulaic Value Investing,” is making the rounds and professes to plunge a dagger directly into the heart of systematic value investors. Half of my inbox is filled with questions regarding this paper, since we are considered by some — rightly or wrongly — to be

Value and Momentum investing have been studied across many different markets and asset classes (Asness et al 2013) and have shown to be effective factors. A working paper, “Frontier Stock Markets: Local vs Global Factors” by Douglas W. Blackburn and Nusret Cakici examines Value and Momentum

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 academic to use

We were recently asked by Aaron Brask, one of our guest bloggers, why we don’t provide a “job board” on our site. Aaron works for several large family offices and he says it is incredibly difficult to find intellectually honest talent. Aaron also pointed out that we have a unique community of

The Dark Side of ETFs? Sounds interesting, and in my humble opinion, an image of Darth Vader on page 1 would be a great addition to the paper. The paper, “Is there a dark side to exchange traded funds? An information perspective,” written by Doron Israeli, Charles M. C. Lee, and Suhas A.

A few years ago, the profitability “quality” factor was originally proposed by Robert Novy-Marx. Here is a snippet from the abstract of the paper: Profitability, measured by gross profits-to-assets, has roughly the same power as book-to-market predicting the cross-section of average returns.

Each year I teach my “seminar in investments” course at Drexel, which consists of the Masters in Finance students and a handful of geeky MBA students. The first few weeks of the course involve an introduction to various investment frameworks and how to navigate the source academic literature.

In this piece I examine various way in which an investor can think about their active market timing decisions, often labeled with the innocuous term “rebalancing.” Rebalancing a portfolio is the finance version of “eat your vegetables” — the advice is taken as gospel, but very few people

Gary Antonacci may not be happy to learn that his "Dual Momentum" label has been pirated by a team of academics (Huang, Zhang, and Zhou)(1)(2) in a new paper that explores the combination of price and fundamental momentum stock-picking strategies. The authors also investigate the common

When it comes to momentum investing, everyone is always looking for a better way to implement a momentum-based stock selection strategy (the same goes for a value strategy). We highlight a few methods in our book, Quantitative Momentum, as well as on our blog. We recently came across a paper from

Johnny Paycheck has a great country song centered around the following lyric: Take this job and shove it…I ain’t working here no more… Campell Harvey, in the 2017 AFA Presidential Address, elaborates an analogous comment on the current state of the financial economics field: Take this alpha

In a recent letter to its investors, Crispin Odey commented as follows:(1) Money managers specializing in picking stocks and bonds are being driven out by mindless passive investing. Odey is a London based hedge fund manager, whose flagship fund lost almost 50% in 2016.(2) Photo courtesy of Wes. All

As my co-author, Andrew Berkin, and I(1) explain in our new book, “Your Complete Guide to Factor-Based Investing,”(2) one of the big problems for the first formal asset pricing model developed by financial economists, the CAPM, was that it predicts a positive relation between risk and return.

Our epic piece on factors from a few weeks ago is still ringing in our own ears: Are factors even real? Or just data-mining? The conclusion: who knows. We need more data. And more data we can find. To include a recent master’s thesis on nordic country equities, which looks at Size, value,

One of the popular investing truisms is the following (inspired by Bill Sharpe): For somebody to beat the market (win) someone else has to lag the market (lose). This becomes an even more daunting (efficient market) statement when changed to the following: For someone to consistently beat the market

The Alpha Architect mission is to empower investors through education.(1) We can’t accomplish our mission without help. Fortunately, “finance twitter” and an explosion of bloggers are helping us achieve our goal. Awesome! Of course, with so many new blogs hitting the scene, we now face an

A recent theory paper from researchers at NYU and Rutgers attempts to explain the empirical evidence on stock serial correlation (e.g., short-term reversal, long-term stock reversal, and classic stock momentum). The interesting wrinkle with this paper is the authors don’t need to assume irrational

Albert Einstein is reported to have said the following: The more I learn, the more I realize how much I don’t know. I can relate. Having studied finance for a long time (PhD, professor, books, articles, etc.), I think I now know less about how the stock market works. In fact, I probably should

Well, I was midway through a formal book review on Larry and Andrew’s new book, “Your Complete Guide to Factor-Based Investing,” when I noticed that the team over at GestaltU already wrote the review I was going to write — great job and I encourage everyone to read it. larry factor book So

I’m a huge fan of hard-core academics that produce incredible research, and yet, very few are familiar with their research. I call these folks, “undiscovered gems.” One might ask why undiscovered gems exist. On one hand, if a researcher produces incredible research, they should be widely

January is here again and market commentators are already telling stories about the so-called January Effect. Some articles (examples here and here) are saying the effect is an illusion, while others are claiming the effect can help you make some profits (examples here and here). Before we dig into

Skewness is a statistical measure of how returns behave in the tails of a probability distribution. Wikipedia has a more robust definition of skewness with some good visuals here. If an investment (e.g., stocks) has negative skewness this means that the extreme returns are more likely to be negative

After reviewing the 2016 performance of trend-following (-18.15%), its unclear why anyone would mention the word “trend following” in a public forum. But we’ll give it a whirl anyway… The comedian Victor Borge once famously observed, “Santa Claus has the right idea – visit people only

The 2017 American Finance Association conference is kicking off later this week in Chicago. If you haven’t been before — check it out. The conference is the biggest meeting of top-tier academic researchers on the planet. You can review all the research being presented at the following link. Some

If you couldn’t tell from our recent monster commodity futures post, we’ve been thinking a lot about futures recently. The futures research area is relatively “fresh,” and a lot more exciting than hacking through equity stock selection research where we already understand the basic answer

There is still no value in bonds today. Many readers just had a knee-jerk reaction and they’ve determined that I fall into one of two categories: A total idiot A total genius But let’s dig a bit deeper into the claim that bonds lack “value,” even with this quarter’s 85 basis point back-up

A few years ago I wrote a summary on a working paper titled “A Lottery Demand-Based Explanation of the Beta Anomaly.” The paper is still a working paper, and has been updated (unfortunately they took out a neat picture from the original paper!). Here is a link to the new version of the paper,

Active investing sounds so easy. But we all know it is extremely difficult. Ask any deep value investor how they have felt over the past few years (although, they are feeling a lot better recently). Certainly, any credible active investor should be able to answer 2 questions: 1) What is the source

Time for a little myth busting. Recently, the Motley Fool posted an article that argued the following: when market volatility is low, protective put options are cheap. From the article: Smart investors know that the time to buy most investments is when most investors aren’t paying attention to

Jack and I had the honor of attending the Evidence-Based Investing conference, hosted by the team at Ritholz Wealth Management. Wow. What a great event and a great group of inspiring investors and thinkers. Abe, Meb, John, Mike, and I had the opportunity to chat about systematic investing. Mr.

Over the past several decades, academics have identified numerous variables that seem to predict future expected returns. This has led to a proliferation of so-called “factors” identified in the literature, and created what John Cochrane has labeled the “factor zoo.” Now we we have a zoo of

At Alpha Architect, we are big fans of Value investing (and Momentum). In the past, Wes and I examined which valuation measure had the largest spread between Value and Growth firms. The evidence showed (updated results here) that Enterprise Multiples had the largest spread between Value and Growth

A sophisticated DFA-focused advisor asked us to conduct some research on the following question: Are there additional portfolio diversification benefits to combining concentrated portfolios of value and momentum stocks relative to combining less concentrated portfolios of value and momentum stocks?

We receive multiple requests from readers looking to break into the finance industry. Quite often the reader is currently working in a traditional engineering job and looking to make a career switch. The question we often hear is “How does an engineer become a quantitative finance geek?” To

Eugene Fama’s Efficient Market Hypothesis argues that because stock prices follow a “random walk,” future price behavior cannot be predicted. In his seminal paper, “Random Walks in Stock Market Prices,” he explains the relationship between prices and fundamentals: If the random-walk theory

Since we’ve released our new book, Quantitative Momentum, we’ve received a handful of basic questions related to momentum–specifically as it relates to stock selection. At this point, the so-called “momentum effect” has occupied academic researchers for several decades. Researchers have

So you’re a trend-follower. Great. But here is a question: What do you invest in when your rules suggest “risk off?” Many investors suggest low duration cash or t-bills. Seems reasonable. But is it optimal? Perhaps we should invest in longer duration risk-off assets like 10-yr bonds? We

The dot-com bubble of the late 90s was a wild time in the stock market. Internet stocks were trading through the roof, tech IPOs were a practically daily experience, and people quit their jobs to make millions day trading. And why not? Even a day trading chimp could make money in a market that went

During the past few decades, newly discovered stock anomalies have been embarrassing existing factor models, such as the Fama-French 3-factor. As many readers know, each long or short “leg” of these popular long/short factor portfolios is generally constructed by ranking stocks on one specific

The long wait is over. Our newest book–Quantitative Momentum–is finally here. After 2 years of research review, results replication, reverse engineering, internal idea generation, writing, editing, and final publication, we have a final product. We think the book will help fulfill our firm

How do stock prices react to earnings announcements? Sometimes prices go up, and sometimes they go down. But here is a potentially more interesting question: What is the average performance across all stocks that have an announcement? The question of whether stocks earn excess returns in

Low volatility funds are some of the best performers in the market these days. As such, they have attracted renewed attention in addition to significant asset flows. (note: a refresher on low volatility investing is here, h.t. Eric Falkenstein). But a question remains — What does the future hold

The prospect of being able to successfully anticipate and predict future market returns is irresistible to practitioners and academics alike, although success has proven elusive. Many have fallen short while seeking this “holy grail” of investing. For instance, Goyal and Welch (2008) examined

Stock market anomalies behave in mysterious ways. Over long periods of time they can provide expected outperformance versus passive indexes, but in the short run they can experience bouts of gut-wrenching underperformance (e.g., value and momentum). What accounts for this sporadic performance and

Most people look back at the dot-com bubble and acknowledge valuations were elevated far above historical norms. Investors ignored historically useful fundamentals, such as earnings and book value, and started relying on measures like eyeballs and clicks. Investors really started to believe, “This

We believe deeply in the value philosophy as first described by Ben Graham: view stocks as ownership in a firm; buy with a margin of safety; avoid stories; think independently; and so forth. In fact, I was so intellectually stimulated by value investing I wrote my dissertation on the subject,

The promise of active investing is compelling: the opportunity to earn higher risk-adjusted returns! And paying a fee to an active manager–who is doing something unique–can make sense. And as we know, the only way to beat a benchmark is by being different from the benchmark, as we discuss here.

Sometimes even the best evidence-based active investment strategies can create a formidable challenge to investors seeking to exploit them. Case in point — momentum investing. On the one hand, stock-selection momentum strategies (here is a link to more information) can have the potential to

The academic standard for intermediate-term momentum measurement is “12_2 momentum:” simply sort all stocks based on a stock’s total return over the past twelve months, ignoring the last month. (a discussion is here and here) However, a few years ago Robert Novy-Marx wrote a paper titled “Is
