In this article, we’ll explore…
- The Impact of Emotion on Investment Outcomes: How fear, overconfidence, and reactive decision-making can detract from long-term performance.
- Closing the “Behavior Gap”: Why investors often underperform the markets they invest in—and the role discipline plays in narrowing that gap.
- The Value of a Rules-Based Investment Process: How a structured, data-driven approach removes subjectivity and promotes consistency across market cycles.
- Strengthening Alignment Between Strategy and Discipline: Why pairing behavioral guidance with a systematic investment framework can support more consistent client outcomes.
Many investors know they should not make decisions based on fear or greed. Very few actually manage to avoid it.
The gap between knowing and doing is where so much investment underperformance is created. And it is a gap that a rules-based, disciplined process is specifically designed to close.
At CooksonPeirce, removing emotion from the investment equation is not an aspiration. It is the architecture of how we manage money, and it has been since our founders built the firm’s original process in 1984.
THE BEHAVIOR GAP IS REAL AND COSTLY
Decades of research in behavioral finance have documented what even seasoned advisors recognize intuitively: investors consistently underperform the very funds they invest in, a pattern often attributed to buying high and selling low. They chase recent winners, panic during drawdowns, and hold on to losers long after the evidence suggests they should move on.
Dalbar’s annual Quantitative Analysis of Investor Behavior has tracked this phenomenon for years, consistently finding that the average equity investor meaningfully underperforms the broad market over long time periods, not because the market failed them, but because their own decisions did.
Behavioral finance research points to emotion as the primary culprit. Hope, fear, regret, and overconfidence all distort the decision-making process in ways that compound over time.
Emotion doesn’t just lead to bad individual decisions. It can lead to a pattern of bad decisions that erodes long-term returns over time.
WHAT A RULES-BASED PROCESS ACTUALLY LOOKS LIKE
Removing emotion from investing does not mean ignoring context or acting mechanically without judgment. It means building a process where the criteria for buying and selling are defined in advance, applied consistently, and not subject to override based on how the market feels on a given day.
At CooksonPeirce, our investment process works as follows:
- We use proprietary relative strength and momentum signals to identify securities with the strongest trends across the full market cap spectrum.
- We construct a concentrated portfolio of typically 25 to 40 positions selected from that universe.
- We apply a mathematical sell discipline. When a position no longer meets our criteria, we exit, regardless of how compelling the story sounds or how recently we purchased it.
- We do not make exceptions for names we like, sectors we favor, or market narratives we find persuasive. The data drives the decision.
This approach is designed to do two things simultaneously: capture winning trends while they remain intact, and exit losing positions before they do serious damage to the portfolio. Neither of those things happens reliably when emotion is part of the equation.
THE HARDEST PART IS STAYING CONSISTENT
Rules-based investing sounds straightforward until the market is in turmoil and every instinct is telling you to do something. The discipline required to hold a process steady during volatile periods is one of the most valuable things a professional investment manager can provide.
We have managed through multiple market cycles since 1984. Tech boom and bust. The financial crisis. The pandemic. In each case, our process gave us a framework for making decisions based on what the data showed, rather than what the headlines said. That consistency is something we believe is difficult to replicate by reacting to market conditions in real time.
what this means for ADVISORS
For financial advisors, the behavioral component of investing is increasingly recognized as central to client outcomes. Helping clients stay invested through volatility, avoid performance chasing, and maintain a long-term perspective is some of the most valuable work an advisor does.
Pairing that behavioral coaching with a strategy that is itself structurally insulated from emotional decision-making creates a powerful combination. Your clients get a disciplined process at the portfolio level that reinforces the discipline you are encouraging at the planning level.
We believe that alignment between advisor and manager philosophy is worth looking for. If a rules-based, momentum-driven approach resonates with how you think about investing, we would welcome a conversation.
