Evidence supporting factor-based seasonalities
Factor seasonality reflects its own stock-level equivalent. It is not an independent risk factor.
Investor demand, rating reform and equity returns
The traditional financial theory attributes security returns to market- or factor-based risk, with no role ascribed to other influences. In this research, the authors argue for including investor demand as an additional variable in explaining returns. Can changes in investor demand generate systematic changes in security returns?
Doug Discusses 1042 QRP and ESOP Transactions
Doug Pugliese, the head of our 1042 QRP business, was recently invited on the ScuttleButt Podcast to discuss the ESOP landscape and the costs and benefits of 1042 QRP transactions. (article on the topic is here).
Reducing the Risk of Momentum Crashes
The empirical research demonstrates that, on average, investing in previous winners and short selling previous losers offers highly significant returns that other common risk factors cannot explain. However, momentum also displays huge tail risk, as there are short but persistent periods of highly negative returns. Crashes occur particularly in reversals from bear markets when the momentum portfolio displays a negative market beta and momentum volatility is high.
Fundamentals and the Attenuation of Anomalies
The article aims to explore the possibility that changes in fundamentals play a role in the attenuation of stock market anomalies, offering an alternative explanation to the prevailing arbitrage-based explanation
Industry classification and the momentum factor
This paper finds that the level of industry classification plays a significant role in the performance of industry momentum strategies.
2023 Democratize Quant Conference Recap and Materials
We recently hosted our 6th Annual Democratize Quant Conference. This post is a recap of what we heard and some resources we can make available to the public.
Reducing the Impact of Momentum Crashes
Momentum crashes are a blight on the performance of momentum strategies. Although there has been a fair amount of research on the topic, few practical solutions have emerged to mitigate the impact on portfolios. In this study, the authors document the outperformance of stocks, in terms of momentum, far away from their peak position relative to stocks very near their peaks. Turns out the outperformance is very large. It also accounts for the majority of negative momentum performance.

Novel explanations for risk-based option momentum
In this paper, we propose a cross-sectional option momentum strategy that is based on the risk component of delta-hedged option returns. We find strong evidence of risk continuation in option returns.
How factor exposure changes over time: a study of Information Decay
Factor strategies need to be rebalanced in order to maintain their factor exposure. But different factors decay at different rates and this affects how they should be rebalanced. For example, momentum needs to be rebalanced more than value. This study digs into these questions.
Combining Reversals with Time-Series Momentum Strategies
Jiadong Liu and Fotis Papailias contribute to the momentum literature with their study “Time Series Reversal in Trend-Following Strategies,” published in the January 2023 issue of “European Financial Management,” in which they examined the reversal property of various financial assets.
Can We Improve Momentum Factor Investing via Salience Theory?
The contribution of salience theory to the theory of asset pricing turns out to be quite a profitable insight for momentum strategies.
Does Momentum work in Option Markets?
This paper explores the question of option momentum by examining what the research says about the performance of option investments across different stocks.
Is there a theoretical foundation behind industry and factor momentum
Industry and factor momentum should be viewed as recent developments in the wider momentum story, although these aggregated measures of momentum lack any theoretical foundation.
The Cross Section of Stock Returns Pre-CRSP data: Value and Momentum are confirmed as robust anomalies
We study the cross-section of stock returns using a novel constructed database of U.S. stocks covering 61 years of independent data.
Momentum Factor Investing: 30 years of Out of Sample Data
In this article, the author examines the research published over the last 30 years on momentum and its theoretical credibility. One of the original momentum articles was published by Jegadeesh and Titman in 1993, and is considered the seminal work on the topic. The research review contained in this publication begins with the 1993 work and confines itself to only the highest quality journals among the plethora of work that has been published on momentum.
Mind the Momentum Gap to Improve Performance
This article discusses the academic research about the Momentum Gap and the role that its predictive potential may have in reducing momentum crashes, hence possibly improving performance.
Momentum Everywhere, Including Emerging Markets
Atilgan et al. contribute to the momentum literature with “Momentum and Downside Risk in Emerging Markets.”
