One of the mistakes that prevent investors from achieving their goals is that when it comes to evaluating investments and investment strategies most think that three years is a long time, five years a very [...]

As my co-author Andrew Berkin, the director of research for Bridgeway Capital Management, and I explain in our new book, “Your Complete Guide to Factor-Based Investing,” there is considerable evidence of cross-sectional return predictability. Citing [...]
The first prediction in the paper is that "Capital Gains and Dividends Viewed as Distinct Desirable Attributes". But what does that mean? The authors highlight that when assessing stock positions, an investor has two options for how to assess the performance -- (1) simple price appreciation/depreciation or (2) total return. Note that price appreciation/depreciation is simply the price appreciation/depreciation on the position, while total return includes both the price appreciation/depreciation plus the dividend return. Directly from the paper: For many positions, either price changes or returns including dividends will yield the same category of gain or loss. However, some positions are at a gain when dividends are included, but at a loss without their inclusion. Do investors treat such positions as being at a gain or at a loss when evaluating whether to sell the position? This is equivalent to asking whether investors adjust for the mechanical decrease in shares price that results from dividend payments.
One of the great debates in finance is whether the source of the value premium is risk-based or a behavioral anomaly. In our book, “Your Complete Guide to Factor-Based Investing,” my co-author Andrew Berkin and [...]
Why do CEOs decide to pay dividends? That is an interesting question, and one that academics have been researching for years. Miller and Modigiliani in 1961 show that if one assumes perfect and efficient capital [...]
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 [...]
David Smith, Na Wang, Ying Wang and Edward Zychowicz contribute to the literature on momentum with their paper, “Sentiment and the Effectiveness of Technical Analysis: Evidence from the Hedge Fund Industry,” which was published in the December 2016 issue of the Journal of Financial and Quantitative Analysis. Their work examines how investor sentiment affects the effectiveness of technical analysis strategies (which include the use of moving averages as well as momentum) used by hedge funds (which are considered sophisticated investors).The study was motivated by prior research that has focused on “investor sentiment,” which is the propensity of individuals to trade on noise and emotions rather than facts. Sentiment causes investors to have beliefs about future cash flows and investment risks that aren’t justified. Two researchers, Malcolm Baker and Jeffrey Wurgler, constructed an investor sentiment index based on six measures: trading volume as measured by NYSE turnover; the dividend premium (the difference between the average market-to-book ratio of dividend-payers and non-payers); the closed-end fund discount; the number and first-day returns of IPOs; and the equity share in new issues. Data is available at through Wurgler and New York University.
Psychology permeates nearly every area of human endeavor. In the world of investing, for instance, psychology can help us understand the systematically poor decision-making that drives the academic anomalies explored on this blog. One cannot [...]

A few months ago I had the pleasure of hearing Sarah Newcomb speak at a recent Morningstar ETF conference. She was extraordinary. Although I only caught the last 20 minutes of her talk, she had [...]
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, [...]

Making choices can be difficult, but possible alternatives can be arranged in a way that facilitates effective decision-making. This is the idea behind “choice architecture,” an concept that is explored in the book, “Nudge,” by [...]

At this point, even hard core efficient market fans will likely admit that behavior can influence investment decisions. Humans aren't robots. However, just because some investors exhibit bad behavior that doesn't mean they can influence prices. As the story [...]
