Low volatility strategies have garnered a fair amount of popularity and a growing body of supporting research. Studies have shown risk reduction levels of 25%, while turnover has varied from 20% to 120%. However, higher turnover produces higher costs of trading, such that the excess return obtained

Everyone in finance remembers 2008–the Global Financial Crisis. Yes, I know, the final downward movement in the stock market was in early 2009. However, many remember 2008 as the year of the crisis. So now we are 10 years removed from the crisis. Why do I mention this? After the crisis, some began

One of the oldest and most persuasive arguments in the stock market is that small stocks outperform large stocks.(1) Warren Buffett, speaking at the 2013 Berkshire Hathaway Annual Meeting, summarized the sentiment when discussing the disadvantages of managing a huge amount of capital: There’s no

What are the research questions? The main purpose of this study was to examine the changes in the distribution of the US equity risk premium as the return horizon varies over the short term, medium and long term (see here for a piece that covers those topics). In this recap, we look at ancillary

We have all heard the mantra, “You can’t time the market!” But in reality, investors attempt to do just that every day as part of their tactical asset allocation strategies, which are less extreme variants of the classic trend-following “risk-on/risk-off” approach, which many associate

What are the Research Questions? The authors investigate the asset pricing implications of corporate manager sentiment, focusing on its predictability for future U.S. stock market returns. Specifically, they ask the following research questions: Does high corporate manager sentiment lead to

The purpose of this study was to examine the changes in the distribution of the US equity risk premium as the return horizon varies from monthly, annually, 3 year, 5 year, 10 year, 20 and 30 year periods. The equity premium was calculated as the monthly difference between the Market and Treasury

Unless you are a die-hard buy-and-hold investor, chances are that you need to rebalance your portfolio at some point. The question is when? And how often? And why at a specific time? Some strategies rebalance once a year, some multiple times a day. What if there were better times to rebalance? Last

What are the Research Questions? Can investors identify skilled and unskilled mutual fund managers by observing their tendency to herd? Do differences in herding behavior across funds predict mutual fund performance? Does skill drives the link between herding and future performance? Does herding

As the year turns, a common practice is to assess a portfolio and see how each position performed. The summary for stocks is easy: equities did not do well. Whether you were invested in U.S. stocks (down ~5%+), developed markets (down ~13%+), or emerging markets (down ~20%+), being invested in

Each time S&P Dow Jones Indices publishes its latest Active Versus Passive Scorecard, the persistent failure of the vast majority of actively managed funds to outperform is highlighted. The evidence on this failure led Charles Ellis to call active management the loser’s game — while it’s

In the last post in our machine learning series, we showed how nonlinear regression algos might improve regression forecasting relative to plain vanilla linear regression (i.e., when underlying reality is nonlinear with complex interactions). In this piece, we’ll first review machine learning for

What are the Research Questions? This editorial introduces data science to the wider investment community and highlights some of the advantages (and potential pitfalls as discussed yesterday) it can bring to everyday investment practice. The paper answers two apparently simple questions: What is

What are the Research Questions? Data mining in finance has long been a concern for academic researchers. Campbell Harvey, one of the authors on this paper, is leading the effort to ensure the integrity of empirical finance research. For example, see here for a post on his address to the AFA. The

This week Ryan and I discuss two posts. First, we examine a guest post by Matthew Bartolini of State Street Global Advisors, discussing the underperformance of Value and its outlook for 2019. Second, we examine a guest post by Elisabetta on a recent JPM paper examining the effects that ETFs have had

Borne in academia and raised by fund managers seeking to outperform, value style mutual funds and ETFs today hold close to $2 trillion(1). But with poor returns over the past decade, the question of whether “value is dead” has become a popular topic of conversation.(2) The search term “is

What are the Research Questions? The paper investigates the following research question: Have ETFs flows affected the correlation structure of returns? Have ETFs flows affected the liquidity of underlying securities? Have ETFs flows affected the ability of managers to generate alpha? What are the

Trend following is well-known and the simplest version is as follows: you buy an asset when it has positive momentum (the price goes up) and you sell it and go to cash (or any other safe haven) when the momentum turns negative.(1) The best-known example of trend following is on the monthly ETF SPY

You can watch the video via the link below: This week Ryan and I discuss three posts. First, we examine a guest post titled, “Trend Following on Steroids,” which examines ways to enhance a simple trend-following strategy. Second, we examine a post I wrote regarding how to use trend-following

A question we have been receiving recently is the following: How should I use trend following within a portfolio? Generally, the questions are related to our Global Value, Momentum, and Trend Index, which allocates to the (1) Value, (2) Momentum, and (3) Trend factors. A big difference between the

What are the research questions? USES: Can investors really separate “alpha” from “beta”? What are the ins-and-outs of understanding the exposures in a portfolio and their contribution to “alpha”? ABUSES: Are there differences in the way strategies are constructed in academic articles

What are the Research Questions? The authors propose an estimation of the capital stock that involves all identifiable and measurable financial and nonfinancial assets in the world economy. This portfolio seeks to represent the so-called “Global Market Portfolio,” that all MBA students learn to

Who are the buyers and sellers of volatility-contingent strategies? How extensive is volatility trading and put selling currently? Could a volatility “cascade” cause a crash across correlated asset classes? Are there mechanisms that might provide stabilization? What are the Academic Insights?

This week Ryan and I discuss three topics. First, we examine the returns to U.S. stock broken down by (1) size and (2) factors (mega-cap stocks were the place to invest over the last 5 years!). Second, we examine a post by Adam Tkaczuk on Opportunity Zones–a must read for those with low basis

The “stock market,” at least as measured via the S&P 500, has been on an epic performance run — especially relative to almost all asset classes. It doesn’t matter whether you look at the other asset classes by geography (e.g., US, developed, emerging), style (e.g., value, momentum), or

What are the research questions? Do hedge funds exploit stock mispricing? Specifically, do hedge funds tend to hold undervalued stocks that exhibit positive alphas? Do hedge funds profit from these holdings in undervalued stocks? Does the trading in these stock reduce mispricing? What are the

The article addresses the estimation of capacity for an equity fund that forms portfolios based on a given investment strategy. It fits within three strands of literature: i) theoretical models of optimal trading or portfolio construction under alpha erosion and trade frictions; ii) empirical

This week Ryan and I discuss two topics. First, we discuss a paper examining the performance of bank affiliated mutual funds. Second, we examine a post by Larry Swedroe on diversification. Paper Links: Do Bank Affiliated Funds Underperform Affiliated Funds? Asset Diversification in a Flat World.

Diversification is a fundamental principle of prudent investing due to its ability to mitigate/minimize risks. In fact, it has been called the only free lunch in investing because, done properly, it can reduce risk without reducing expected returns. This led to the conclusion that investors should

You can watch the video via the link below: This week Ryan and Jack discuss several important topics. First, they discuss the tracking error associated with trend-following strategies. Second, they chat about a paper by researchers from Goldman Sachs, “Constructing Long-Only Multifactor

A question I’ve received in the past is the following: If you could go back in time five years ago and tell yourself something about investing, what would it be? My response is the following: Tracking error. First, what is tracking error?(1) Tracking error is a measure of how much a strategy

The heightened interest in factor investing has been accompanied by a corresponding focus on the nuts and bolts of constructing multifactor portfolios. There are essentially two ways to go: In a one-step process, single factor signals are blended into a composite signal and one multifactor portfolio

This week Ryan and I have a discussion on three topics. First, we discuss ETF tax efficiency based on the findings in a new paper by the RAFI team. Second, we discuss the profitability factor as Larry Swedroe highlights a new paper on international evidence. Third, we discuss my article on how one

Robert Novy-Marx’s 2013 paper “The Other Side of Value: The Gross Profitability Premium” not only provided investors with new insights into the cross-section of stock returns, but also helped further explain some of Warren Buffett’s superior performance. (Wes Gray summarized that paper

“What is the correct benchmark for trend following?” This is a difficult question, and there really is no perfect answer. As many of our readers know, we are fans of trend following and trend-followed portfolios. For those unfamiliar with trend following, the idea is rather simple–invest in an

The CAPM was the first formal asset-pricing model. Market beta was its sole factor. With the 1992 publication of their paper, “The Cross-Section of Expected Stock Returns,” Eugene Fama and Kenneth French introduced a new-and-improved three-factor model, adding size and value to market beta as

Factors, or “style” investing, seems to be all the rage these days, including the use of factors in fixed income (here, here and here are good places to start). However, many of these strategies focus on CUSIP level bond selection. This means executing a strategy with a fair amount of turnover

Is it possible to time factors? (An old blog on the topic here and Jack discussing on a podcast here) Are there financial and economic indicators that can be used to predict factor returns? Are timing models just luck? What are the Academic Insights? YES. The authors use Fama-French 5 Factors

Not long ago I used to teach investment management courses to Master’s students (MBAs and MS Finance types). A core aspect of my course was so-called modern portfolio theory. We did a lot of math and problem-sets to make it feel like we were doing something useful. But I can summarize the core

“How can a q-theoretic model price momentum?” is a new paper by Robert Novy-Marx and goes right to the heart of an intense debate ongoing in empirical asset pricing — can neoclassic economic models explain the so-called momentum anomaly? A quote from the start of the paper, which answers the

The paper investigates the following research question: Are left-tail vs. right-tail correlations symmetric for the majority of risky assets (including size and styles)? Is left-tail vs. right-tail correlations between stocks and hedge funds styles symmetric? Is left-tail vs. right-tail correlations

Early in the summer, I was on a podcast with Corey Hoffstein discussing momentum investing. During the discussion, Corey asked me a question regarding risk versus mispricing, specific to the momentum anomaly. We frequently cite the behavioral explanation for momentum–investors tend to underreact
