Why your brain sabotage your investments

Your relationship with money isn't just about numbers--it's deeply personal, shaped by your entire life experience.

The Hidden Forces Driving Your Financial Decisions

Do you think that your financial decisions are rational? Think again. You subconsciously make most financial decisions.

  • The brain feels losses more intensely (losing $1000 feels worse than winning $1000 feels good).
  • Market crashes become real threats with the help of evolutionary wiring
  • Fear and greed drives more investment decisions that logical analysis will ever do

Your financial future is shaped by the past.

Remember how you and your family discussed money in childhood? Those early experiences created financial imprints that still influence how you react to market movements today:

  • Early experiences with money can form neural pathways lasting decades
  • It is difficult to overcome the biases that are formed by experiencing market crashes.
  • Your personal financial background has more impact on your risk-tolerance than any finance course

Why Knowing better doesn't necessarily mean doing better

This is the sad truth: Knowing what to spend your money on doesn't ensure you'll do it. Even financial experts can make emotional decisions.

  • Market panic can override logical thinking in seconds
  • Investments suffer more from implementation problems than from knowledge gaps
  • Information alone rarely changes deep-seated financial behaviors

Behavioral Finance, The Science Behind Market Madness

In traditional economics, we were assumed to be rational investors. Behavioral finance shows how emotions drive market moves.

From Rational Theory To Emotional Reality

Researchers first noticed a pattern of irrational finance behavior.

  • Classical economists cannot explain why markets always overreact
  • In the 1970s, psychologists Kahneman and Tversky transformed our understanding.
  • The 2008 financial crash pushed behavioral financing into the mainstream

Why Markets Aren't Always Rational

Despite what the textbooks say, markets aren't perfectly efficient. Human psychology creates persistent inefficiencies:

  • Assets are often mispriced due to emotional reactions
  • Investor herding generates boom-bust cycles that transcend fundamental values
  • Bubbles and market crashes are caused by psychological factors

Investment Principles that Every Investor Must Know

These core concepts will help you identify when your emotions are clouding your judgment.

  • Loss aversion is a phenomenon where losses hurt about twice as bad as similar gains.
  • Recency bias is the tendency to give too much weighting to what happened most recently.
  • Anchoring effect: Tying decisions to arbitrary reference points rather than fundamentals

The emotional investing traps we all fall into

The brain is full of shortcuts. These helped our ancestors to survive, but they can ruin your investment returns. Let's identify these biases so you can overcome them.

Make Money-Worrying Mistakes based on Fear

Fear is the emotion that drives more expensive investing mistakes than any other emotion.

  • Loss aversion causes you to sell winners too soon and hold losers for too long.
  • The risk-averse attitude increases when the opportunities are at their greatest
  • Catastrophizing results in excessive cash positions which are slowly eroded by inflation

When Greed takes the Wheel

You can be tempted to take excessive risk during bull markets by your optimism bias.

  • Overconfidence causes you to underestimate risks and overestimate your abilities
  • FOMO (fear of missing out) drives you to chase performance in hot sectors
  • Selective memory helps you forget past mistakes during market euphoria

All Investors Have Cognitive Blindspots

Your brain is constantly looking for information that will confirm your beliefs.

  • Confirmation bias leads you to ignore warning signs in investments you love
  • Mental accounting leads to inconsistent risk management across accounts
  • Sunk Cost Fallacy: You are stuck with losing strategies because of "you have already invested so many dollars"

The Four Market Cycles and Their Emotional Roller Coaster

The emotional cycles of the markets are as predictable as their patterns of price. You will gain an enormous advantage if you can identify the emotional stage in which the market is at.

Bull Market Psychology: A dangerous path to Euphoria

Bull markets tend to follow an emotional progression that is predictable:

  • Early optimism opens up solid opportunities for reasonable pricing
  • Middle appreciation boosts confidence but leads to complacency
  • As rational analysis is ignored, the euphoria signal danger

Bear Market Psychology - From Denial to Opportunity

Bear markets cause emotional reactions that are predictable.

  • When markets start to decline, investors are still unable to sell their investments.
  • Fear of losses prompts widespread sales
  • In the midst of maximum pessimism, surrendering creates the best opportunities

Psychological insights can help you identify turning points in the market.

Investor psychology is the first to change, followed by prices.

  • Excessive optimism often signals market tops before prices actually peak
  • Widespread market capitulation is usually followed by a bottom.
  • Sentiment can lead to price movements in weeks or years.

Practical Ways to Manage your Emotions during Market Chaos

Managing your emotional response to market swings is a skill you can learn. Try these techniques to stay rational when markets get turbulent.

Mindfulness Practices that Improve Investment Decisions

Awareness of your emotional reactions can help you make more rational choices.

  • Regular meditation improves emotional regulation during market stress
  • Body scanning identifies anxiety in your decisions
  • Emotional labeling ("I'm feeling fearful right now") reduces reaction intensity

Why Investment Journaling Transforms Your Results

This simple action improves the decision quality dramatically.

  • Investment journals provide objective documentation of your thinking
  • Tracing emotions along with decisions reveals harmful patterns
  • Regular reflection increases your awareness of personal financial triggers

Psychological Distance is a powerful tool

By viewing the market volatility with a detached view, emotional reactivity is reduced:

  • Try imagining giving advice to a friend instead of yourself
  • Use the third-person when evaluating decisions ("What would Jane do?").
  • Prioritize long-term results over short-term feelings by visualizing your future self

Building an investment strategy to work with your Psychology

The best investment strategies take into consideration your psychological tendencies. Aligning your approach with your emotional realities improves long-term results.

Investing Rules-Based: Emotional Circuitbreakers

Clear investment rules established in advance prevent emotional override:

  • Pre-commitment strategies prevent impulsive decisions during volatility
  • Rebalancing laws force counter-productive behavior when emotions resist
  • Systematic investment plans eliminate timing decisions entirely

Finding Your Sleep at-Night Factor

Position sizing is important to stay invested during turbulent market conditions.

  • Positions are small enough to stop panic selling in downturns
  • Diversification reduces emotional attachment to individual investments
  • Risk management regulations prevent catastrophic failures that cause abandonment.

Matching the emotional capacity of a person to their timeframe

Different time horizons require different psychological approaches:

  • Longer time horizons reduce emotional reactivity to short-term volatility
  • Distinct strategies for different goals improve overall stability
  • Mental preparation for expected volatility reduces surprise reactions

Social Psychology of Market Psychology

Markets are social organizations where collective psychology is driving price movements. Understanding these dynamics helps you resist unhealthy social pressures.

Why We Can't Stop Following the Herd

Humans evolved to follow the crowd for safety:

  • Social proof leads investors to popular investments near top of market
  • Herding explains the reasons why markets overshoot both directions
  • Herding behaviour can create opportunities for contrarians when it reaches extremes

Media narratives and market movements

Financial media can amplify emotional extremes by compelling stories

  • Market movements are not led by news coverage, but rather follow them.
  • Media narratives simplify complicated dynamics into dramatic storylines
  • Headlines affect your emotions more during periods of market stress

If everyone agrees, you can still think independently

The courage to think independently creates significant advantages:

  • Cultivate a diverse information diet to reduce narrative capture
  • To strengthen your investment thesis, look for evidence that contradicts the current beliefs.
  • Contrarian thinking produces best results at market extremes

Creating a Healthy Relationship with Money

Your relationship with money is a major factor in your investing experience. Clarifying the money philosophy you follow can help improve your decision making during market fluctuations.

Redefining wealth on your terms

Wealth is different for different people.

  • The freedom to spend money on what you want is more rewarding than accumulating.
  • When you know "enough", it reduces comparison.
  • The ability to manage your time is more important than having absolute wealth

Aligning your money with Your Values

Investment decisions reflect your deeper values:

  • Value-aligned investments reduce cognitive dissonance during volatility
  • When markets are turbulent, personal purpose can provide stability
  • The ethical considerations of long-term strategies create a greater commitment

Finding Your Balance Between Today and Tomorrow

Money serves both present needs and future goals:

  • The over-saving of money could lead to unnecessary present sacrifice
  • Under-saving creates future anxiety that diminishes today's enjoyment
  • The balance point that you choose depends on your individual values and circumstances

The Emotional Health Management System: Your Action Plan

Theory becomes valuable when implemented. Create a personalized emotional management approach.

Create Your Investor Policy Statement

A written investment policy statement creates a stable reference point during market turbulence:

  • Document your investment philosophy in advance of market stress
  • Include specific guidelines for actions during market extremes
  • Review your review annually but only make minor modifications to maintain consistency

Create Your Own Circuit breakers

Predetermined pause points prevent reactive decisions during high-emotion periods:

  • Prior to making major portfolio changes, there are waiting periods that must be observed.
  • Asset allocation safeguards that limit maximum adjustments
  • Trusted advisors who provide perspective during emotional periods

Turn Every Market Cycle Into a Learning Opportunity

Market experience is transformed into valuable knowledge through systematic review.

  • After-action reviews reveal emotional patterns
  • Instead of focusing on outcomes, focus more on the process.
  • The investment lifetime for small improvements is long.

Your edge is based on your psychology

Managing your emotions during market swings provides your greatest investment advantage. While you may not be able to control the markets themselves, you are able to control how you respond. That is probably the most valuable skill in investing.
