Today we are exploring a groundbreaking investment strategy that promises stronger returns, less stress, and a fresh perspective on portfolio design. It’s called hierarchical momentum (HM), and it combines two proven concepts in finance: momentum investing and diversification. If you're searching for an approach that aims to grow your wealth while helping you sleep at night, HM might be the strategy you've been waiting for.
The Problem with Traditional Portfolio Strategies
Most traditional portfolio strategies, like the Nobel Prize-winning Markowitz model, were designed in a different era—an era with less data and slower technology. These older models often struggle in today's data-rich environment and may end up suggesting portfolios that are too risky or too concentrated.
In other words, they weren’t built for modern markets.
What Is Hierarchical Momentum?
Hierarchical momentum brings together the power of momentum investing (buying recent winners) with the structure of hierarchical clustering (grouping similar stocks). Think of it like selecting the best dishes from different sections of a gourmet buffet rather than just piling your plate with whatever catches your eye.
Momentum Investing
This approach is based on the idea that stocks that have done well recently are more likely to keep performing well in the short term. It's about riding the "hot hand."
Hierarchical Clustering
Hierarchical clustering groups stocks based on similarities in their price movements—kind of like putting stocks into families that move together. This helps build a diversified portfolio across different market behaviors.
How the Strategy Works
Group similar stocks based on historical price movement.
Within each group, identify the stock with the highest momentum.
Build a portfolio of these top-performers from each group.
Update regularly as relationships and performances evolve.
By diversifying momentum picks across different clusters, you reduce the risk of relying too heavily on any single sector or trend.
Real-World Results
Researchers tested this approach using a large global stock index, and the results were striking:
Higher returns than traditional momentum and benchmark strategies
Lower volatility, meaning fewer dramatic ups and downs
Smaller drawdowns, reducing gut-wrenching losses
Better risk-adjusted performance (higher Sharpe and Sortino ratios)
In short, hierarchical momentum offered a smoother and more robust investing experience.
Why It Matters
What sets hierarchical momentum apart is not just its performance but how it gets those results. It's not relying on a single market signal or trend. Instead, it's capturing deeper, hidden patterns that traditional models often miss.
Some researchers even suggest that HM is tapping into a "sixth sense" of the market—a secret language of price movement and group behavior.
Practical Implementation
Interested in trying this strategy? Here's how to get started:
Collect historical price data for a large set of stocks.
Use clustering algorithms to group similar stocks.
Measure momentum (typically past returns) within each group.
Select the top performer from each group to include in your portfolio.
Exclude stocks with negative momentum to avoid potential losses.
Rebalance periodically to reflect new data and relationships.
A Dynamic and Adaptive Strategy
Markets change, and hierarchical momentum changes with them. As stock relationships evolve, so do the clusters. This keeps the portfolio dynamic, responsive, and better suited to modern investing.
Future Possibilities
While this strategy has been tested on global equities, imagine applying it to other asset classes: bonds, commodities, real estate. The same principles could lead to even broader diversification and stability.
Additionally, we could enhance momentum signals by integrating other factors like earnings surprises or analyst upgrades—tailoring the strategy to individual goals and styles.
Final Thought
Hierarchical momentum isn't just another investing trend. It's a thoughtful, tested strategy that offers a new way of thinking about portfolio construction. By blending diversification with momentum and grounding it in dynamic relationships, HM represents a major step forward in the evolution of modern investing.
If you're looking to upgrade your investing approach, hierarchical momentum could be the smarter, more resilient path forward.
FAQs
What is hierarchical momentum? A strategy that combines momentum investing with hierarchical clustering to create diversified portfolios of top-performing stocks within similar groups.
How does it differ from traditional momentum? Instead of chasing overall top performers, it selects leaders from various market clusters, improving diversification and reducing risk.
Is this strategy only for stocks? So far it's been tested on equities, but the principles could extend to other asset classes like bonds or commodities.
How often should portfolios be rebalanced? It depends on your risk tolerance and goals, but many implementations update monthly or quarterly.
Do I need coding skills to use this strategy? Not necessarily, but familiarity with data analysis tools (like Python or R) can help in executing the clustering and momentum calculations.
