What Kinds of Behaviors Can Prevent People from Making Smart Investing Decisions?

July 1, 2024

By its very nature, investing is a complex endeavour combining elements of financial acumen, psychological resilience, and strategic foresight. However, numerous behaviours and cognitive biases can derail even the most well-intentioned investor from making sound decisions. This essay explores these detrimental behaviours by delving into mass psychology, technical analysis, and cognitive bias, supplemented by the timeless wisdom of historical figures like Hammurabi, Thales of Miletus, Pythagoras, Heraclitus, Socrates, and Plato.

Mass Psychology and Herd Behavior

Mass psychology, which often manifests as herd behaviour, is one of the most pervasive influences on investor behaviour. This is where individuals tend to follow the actions of a larger group, often ignoring their analysis or the fundamentals of the investment. The bandwagon effect can lead to bubbles, as seen in the dot-com boom of the late 1990s and the housing market crash in 2007 and 2008.

Example: During the dot-com bubble, many investors bought into tech stocks simply because everyone else was doing so. Companies with little to no earnings were valued at astronomical levels, driven by the fear of missing out (FOMO). Thales of Miletus, often regarded as one of the first speculative investors, might advise, “Do not be swayed by the crowd, but rather by the substance of the investment.”

Cognitive Biases

Cognitive biases are systematic patterns of deviation from norm or rationality in judgment. These biases can significantly impair decision-making processes. Some of the most common biases that affect investors include:

1. Overconfidence Bias: Many investors overestimate their knowledge or predictive abilities, leading them to take excessive risks. Pythagoras, known for his contributions to mathematics and philosophy, might suggest, “Measure twice, cut once.” In investing, this could translate to double-checking one’s assumptions and analyses before making a decision.

2. Confirmation Bias: This bias leads investors to seek information confirming their preexisting beliefs while ignoring contradictory data. Heraclitus, who believed in the constant flux of life, might remind us, “The only constant is change.” In the world of investing, this means being open to new information and adjusting one’s strategies accordingly.

3. Anchoring bias: This is the tendency to rely too heavily on the first piece of information encountered (the “anchor”) when making decisions. For instance, if an investor buys a stock at $100, they might irrationally hold onto it even as it plummets, anchored to its initial price. Socrates, who valued questioning and critical thinking, would likely advise, “Know thyself,” encouraging investors to be aware of their biases and adjust their strategies accordingly.

Technical Analysis and Behavioral Pitfalls

Technical analysis, which involves evaluating securities by analyzing statistics generated by market activity, such as past prices and volume, can also be influenced by behavioural pitfalls. For example:

1. Pattern Recognition: Investors might see patterns where none exist, a phenomenon known as apophenia. Plato, who emphasized the importance of ideal forms and rational thought, might argue that “true knowledge comes from understanding the essence of things, not mere appearances.” In investing, this means distinguishing between genuine market signals and random noise.

2. Recency Bias: This is the tendency to give undue weight to recent events when making decisions. For example, if a stock has performed well in the past few months, an investor might irrationally assume it will continue to do so. Hammurabi, known for his code of laws, would likely stress the importance of long-term thinking and consistency in one’s approach rather than being swayed by short-term fluctuations.

Real-Life Example: The 2008 Financial Crisis

The 2008 financial crisis is a poignant example of how these behaviours and biases can lead to disastrous investing decisions. Many investors were caught in a cycle of overconfidence and herd behaviour leading up to the crisis, buying into mortgage-backed securities without fully understanding the risks involved. Confirmation bias led them to ignore warning signs while anchoring to historical home price trends, which made them believe the housing market could never crash.

Contrarian Investing

Contrarian investing is an approach that goes against prevailing market trends. It requires a high degree of independent thinking and psychological resilience. Plato’s allegory of the cave, where prisoners mistake shadows for reality, can be applied here. Contrarian investors seek to understand the true value of an investment rather than being misled by market sentiment.

Example: Warren Buffett, often regarded as the epitome of a contrarian investor, famously advises to “be fearful when others are greedy and greedy when others are fearful.” During the financial crisis, while many investors were panic-selling, Buffett invested in companies like Goldman Sachs and General Electric, which were undervalued due to irrational market fears.

Emotional Control

Emotions play a significant role in investing. Fear and greed are potent drivers that can lead to irrational decision-making. Heraclitus’s constant change and flux philosophy can help investors remain detached and adaptable. Emotional control is crucial for maintaining a long-term perspective and avoiding impulsive decisions.

Example: In the early 2000s, Amazon’s stock price experienced significant volatility. Many investors, driven by fear, sold their shares during downturns. However, those who maintained emotional control and held on to their investments were eventually rewarded as Amazon became one of the most valuable companies in the world.

The Importance of Diversification

Diversification is a fundamental principle of sound investing. Investors can mitigate risk by spreading investments across different asset classes and sectors. Pythagoras’s emphasis on balance and harmony can be applied to portfolio management. A well-diversified portfolio will likely withstand market volatility and provide stable returns.

Example: In the 2000s, many investors invested heavily in technology stocks. When the dot-com bubble burst, those with diversified portfolios suffered less severe losses than those overly concentrated in the tech sector.

The Role of Patience and Discipline

Patience and discipline are fundamental virtues in investing, often separating successful long-term investors from those who fall prey to short-term market fluctuations. Socrates, the father of Western philosophy, emphasized the importance of questioning and seeking more profound understanding. His method, known as the Socratic method, can be applied to investment decisions, encouraging investors to thoroughly examine their motives, assumptions, and the underlying fundamentals of their investments.

Disciplined investors focus on long-term value creation rather than chasing quick profits. This approach aligns with Plato’s concept of the “Forms,” where he argued that true reality exists beyond what we can see or touch. In investing, this translates to looking beyond short-term price movements and focusing on the intrinsic value of an asset.

Heraclitus, known for his doctrine of change, famously said, “No man ever steps in the same river twice, for it’s not the same river, and he’s not the same man.” This philosophy can remind investors that while markets constantly change, patience allows one to ride out short-term volatility and benefit from long-term trends.

Example 1: Berkshire Hathaway and Coca-Cola

Warren Buffett’s Berkshire Hathaway began purchasing shares of Coca-Cola in 1988, accumulating a significant stake by 1989. Despite numerous market downturns and periods of underperformance, Berkshire held onto its Coca-Cola shares for decades. This patience has been rewarded handsomely, with the investment growing from about $1.3 billion to over $22 billion by 2021. This example embodies the Pythagorean principle of harmony and balance, as Buffett recognized the enduring value of Coca-Cola’s brand and business model, maintaining his investment through various market cycles.

Example 2: Amazon’s Long-Term Growth
Amazon’s stock price has seen significant volatility since its IPO in 1997. In the early 2000s, during the dot-com crash, Amazon’s stock price fell by over 90%. Many investors, lacking patience and discipline, sold their shares. However, those who understood Amazon’s long-term potential and held their positions saw tremendous returns. A $1,000 investment in Amazon at its IPO would be worth over $2 million today. This example illustrates Thales of Miletus’s approach to speculation and long-term thinking.

Hammurabi, known for his code of laws, emphasized the importance of fairness and long-term stability. In investing, this translates to maintaining a consistent, disciplined approach rather than constantly changing strategies based on short-term market movements.

Conclusion: What Kinds of Behaviors Can Prevent People from Making Smart Investing Decisions?

Investing is a multifaceted endeavour that demands a comprehensive understanding of market dynamics, psychological fortitude, and strategic vision. Recognizing and mitigating the impact of cognitive biases, emotional impulses, and herd behaviour is crucial for making informed and rational investment decisions.

The wisdom of historical figures provides timeless insights into the principles of sound investing:

1. Hammurabi’s emphasis on fairness and stability reminds us of the importance of consistent, ethical investing practices.

2. Thales of Miletus, often considered one of the first speculative investors, teaches us the value of foresight and calculated risk-taking.

3. Pythagoras’s principles of harmony and balance can be applied to portfolio diversification and risk management.

4. Heraclitus’s doctrine of perpetual change encourages investors to remain adaptable and open to new information.

5. Socrates’s method of questioning prompts investors to examine their assumptions and investment theses critically.

6. Plato’s concept of ideal forms reminds us to look beyond surface-level market movements to understand the actual value of investments.

Successful investing requires a delicate balance of critical thinking, emotional control, and long-term perspective. It’s not merely about analyzing numbers or following market trends but about developing a deep understanding of human behaviour, market psychology, and the underlying drivers of economic value.

Moreover, an investor’s journey is one of continuous learning and self-improvement. As Socrates famously said, “The only true wisdom is knowing you know nothing.” This humility and openness to learning are crucial in the ever-changing landscape of financial markets.

In conclusion, while the principles of intelligent investing may seem straightforward, their consistent application in the face of market volatility, conflicting information, and emotional pressures truly sets successful investors apart. By learning from historical wisdom, understanding our own psychological biases, and maintaining discipline and patience, investors can navigate the complex world of finance and work towards achieving their long-term financial goals.
