The Value and Momentum Trader: Dynamic Stock Selection Models to Beat the Market
By Grant Henning
Quick Summary
A systematic approach to stock selection that combines value investing and momentum trading through mathematical models. Grant Henning develops and presents multiple quantitative systems -- technical-momentum, fundamental-value, and hybrid approaches -- for identifying stocks likely to outperform the market, with an emphasis on practical implementation and risk management.
Executive Summary
"The Value and Momentum Trader" attempts to bridge the gap between value investing and momentum trading by developing mathematical stock selection models that incorporate both disciplines. Henning argues that neither pure value nor pure momentum approaches are sufficient on their own, and that a hybrid system combining both filters produces superior risk-adjusted returns. The book provides the theoretical foundation for each approach, then constructs specific screening criteria with qualifying variables, and finally demonstrates how to combine them. The technical-momentum system uses price-based and volume-based indicators to identify stocks with strong upward momentum, while the fundamental-value system screens for undervalued stocks using earnings, cash flow, and balance sheet metrics. The hybrid approach applies both filters to generate the highest-conviction selections.
Core Thesis
Stock selection is most effective when it combines two complementary approaches: value analysis (identifying companies trading below intrinsic worth) and momentum analysis (identifying stocks exhibiting positive price trends). Mathematical models that systematize this combination can beat the market while managing risk more effectively than discretionary approaches.
Key Systems
Technical-Momentum System
Uses qualifying variables including recent price performance, relative strength, volume patterns, and trend indicators to identify stocks with positive momentum characteristics.
Fundamental-Value System
Screens for stocks based on earnings yield, price-to-book, price-to-earnings, cash flow metrics, debt ratios, and other balance sheet variables to identify undervalued companies.
Hybrid Approach
Combines technical and fundamental filters, including point-and-figure analysis, to generate a smaller universe of high-conviction stock selections that satisfy both value and momentum criteria.
Critical Assessment
Strengths
- Systematic, quantifiable approach to stock selection
- Bridges the value-momentum divide with practical integration
- Provides specific screening criteria that can be replicated
- Addresses common mistakes in system design
Limitations
- Some screening criteria may be overly specific to the historical period tested
- Limited discussion of out-of-sample validation
- The mathematical models could benefit from more rigorous statistical analysis
- Does not adequately address the capacity constraints of the strategies
Conclusion
Henning's contribution is in demonstrating that value and momentum are complementary rather than competing approaches. The book provides a useful framework for building quantitative stock selection systems, though practitioners should independently validate the specific parameters on more recent data.
