Summary
Managing an equity index isn’t about building a static list — it’s about maintaining alignment with the market’s most promising opportunities. This edition explains why active management is essential, when and why companies must be replaced, and how major benchmarks like the S&P 500, NASDAQ, Dow, and Russell 2000 handle their own constituent changes.
Why It’s Important to Manage an Equity Index
An equity index is not a set-and-forget model. It represents a living portfolio that must continually reflect its intended investment theme — whether that’s growth equities or value leaders.
When companies within the index begin to lose momentum, fall behind industry peers, or experience a significant shift in sentiment analysis, the integrity of the index weakens. Regular management ensures the index continues to reflect the strongest, most relevant opportunities available.
Why Replacement Can Be Critical
It may sound counterintuitive, but removing a company can be just as important as adding one. Here’s why proactive updates matter:
Shifting Fundamentals: When earnings growth, margins, or market leadership decline, a replacement preserves the index’s performance intent.
Computational Model Signals: Proprietary models may identify other companies with stronger forward-looking potential. Acting on those signals keeps your index competitive.
Market Representation: Each component must fit the theme — especially for specialized indices like Fintech Wave Alpha (FWA) and Fintech Wave Bravo (FWB).
Opportunity Cost: Underperformers drag on average return. Replacements ensure the index remains a showcase of the best available growth.
Reader Expectation: Newsletter subscribers should expect an index to evolve as data evolves. Transparent updates reinforce credibility and trust.
How Major Benchmarks Handle Changes
Even the world’s largest benchmarks are actively maintained to reflect evolving markets:
Implications for the Fintech Trades Indices
As the portfolio manager of the Fintech Trades Equity Indices, derived from proprietary computational models, I am replacing 1 of the 20 companies in Fintech Wave Alpha (FWA) and 1 of the 10 companies in Fintech Wave Bravo (FWB).
These adjustments reflect the models’ latest signals identifying stronger growth trajectories and improved risk-adjusted return potential. Following these updates, both indices continue to outperform major benchmarks.
Fintech Wave Alpha (FWA) — established on April 17, 2025 — is maintaining a 65% growth rate since inception.
Fintech Wave Bravo (FWB) — launched on September 19, 2025 — is showing an 11% growth rate in less than one month, following a similar upward trajectory.
To preserve this advantage:
Conduct quarterly or semi-annual reviews of all index constituents.
Apply consistent rules for additions and removals based on modeled growth scores and valuation metrics.
Keep the index stable enough to build a long-term performance record, yet flexible enough to capture emerging leaders.
Communicate changes clearly to readers — transparency builds confidence.
In Summary
The purpose of managing an equity index is simple: preserve performance and relevance. Just as the market evolves, so must the index. By periodically evaluating and adjusting the list, I ensure that each company continues to meet growth criteria — keeping the index accurate, credible, and aligned with the fast-moving dynamics of today’s market.
