Emotions and Investing – How Fear and Greed Sabotage Your Financial Decisions

Warren Buffett once said: "Be greedy when others are fearful, and fearful when others are greedy." This quote is repeated so often it has become a cliché. The problem is that almost nobody can actually follow it – because emotions are stronger than rational analysis.

If you have ever sold stocks at the bottom in a panic, bought cryptocurrency at the peak of euphoria, or lost sleep checking your portfolio every hour – you know exactly what this means. Emotions are the most expensive cost of investing, one that never appears on any brokerage statement.

Why Emotions Rule Our Portfolios

Our brains evolved over hundreds of thousands of years in an environment where fast, emotional reactions meant survival. Seeing a tiger and running immediately – that was a good plan. The problem is that the same mechanism activates when you see the WIG20 index drop 5% in a single day.

System 1 and System 2

Daniel Kahneman, the Nobel Prize-winning economist, described two systems of thinking:

• System 1 – fast, automatic, emotional. It reacts instantly, without deeper analysis. It is the system telling you to sell when the market drops and buy when it rises.
• System 2 – slow, analytical, rational. It can calculate rates of return, compare P/E ratios, and evaluate company fundamentals. But it requires effort and is easily overwhelmed.

In investing, you need System 2, but during moments of market stress, System 1 takes control. This is precisely why on the Warsaw Stock Exchange (GPW) – as on every other exchange in the world – the majority of individual investors lose money.

The Neuroscience of Financial Decisions

fMRI research shows that the prospect of profit activates the nucleus accumbens – the same brain region that responds to food, sex, and drugs. Losses, on the other hand, activate the insula and amygdala – centers responsible for pain and fear.

Crucially, the neurological response to a loss is approximately 2.5 times stronger than the response to an equivalent gain. This means losing 1,000 PLN hurts as much as gaining 2,500 PLN feels good. This asymmetry – described by Kahneman and Tversky as loss aversion – is the foundation of emotional investment mistakes.

Fear – The Silent Portfolio Killer

Fear in the market takes many forms. It is not just panic selling during a crash. It encompasses a whole range of behaviors that systematically reduce your returns.

Decision Paralysis

Many beginner investors in Poland postpone entering the market for months or even years. They wait for a "better moment," analyze charts, read forecasts – and ultimately do nothing. Meanwhile, inflation (which in Poland reached as high as 18.4% at its peak in recent years) steadily erodes their savings sitting in a standard bank account.

Research by Dalbar Inc. from the US shows that the average investor achieves returns 3–4 percentage points worse than the index, mainly because they enter and exit the market at the worst possible times. In the Polish market, this effect is likely even more pronounced due to lower levels of financial literacy.

Panic Selling

March 2020. COVID-19 reaches Poland. The WIG20 drops over 35% in a matter of weeks. Panic erupts on investment forums. Many investors sell everything – often at the very bottom. Those who held on recovered their losses within several months. Those who sold turned paper losses into real ones.

A similar scenario has played out multiple times: the 2008 financial crisis, when the WIG fell over 50%, the 2022 bear market caused by interest rate hikes from the NBP's Monetary Policy Council (RPP). Each time the mechanism is the same – fear commands you to sell precisely when you should be buying.

The Disposition Effect

Fear also manifests as holding losing positions too long (because selling would mean admitting a mistake) while simultaneously selling winning positions too quickly (because you fear the gain will "escape"). This is known as the disposition effect, one of the most well-documented behavioral biases.

On the GPW, this is clearly visible: individual investors en masse hold penny stocks that have lost 80% of their value, hoping for a "bounce," while taking profits on solid blue chips after a modest 15–20% gain.

Greed – The Fuel of Speculative Bubbles

If fear makes you flee, greed makes you chase. And both emotions lead to the same losses.

The Cryptocurrency Mania in Poland

The Polish cryptocurrency fever of 2017 is a perfect example of greed in action. Bitcoin rose from a few thousand to tens of thousands of zlotys. Stories appeared on forums about people who had "made a million." Students took out consumer loans to buy crypto. Taxi drivers gave investment advice.

Then January 2018 arrived, and the price dropped over 80%. Those who bought at the peak of euphoria lost their life savings. Some lost borrowed money.

Excessive Risk-Taking

Greed also manifests as taking on excessive risk: investing without diversification (your entire portfolio in one stock), using leverage on the Forex or CFD market (where KNF statistics show that 70–80% of clients lose money), or ignoring the fundamental rule – never invest money you cannot afford to lose.

FOMO – Greed in Disguise

FOMO (Fear Of Missing Out) is actually greed wearing the mask of fear. You are not afraid of a loss – you are afraid that others will profit while you do not. This causes herd buying of assets that have already risen, without any fundamental analysis. In the Polish market, FOMO appears regularly with each new trend – gaming stocks one year (CD Projekt at its 2020 peak), solar energy companies the next, and AI-related stocks after that.

Other Emotions That Cost Money

Overconfidence

Research shows that after a series of successful trades, investors begin to believe they have a "talent" for investing. They increase position sizes, trade more frequently, and stop using stop-losses. This is a classic error – confusing luck with skill.

On the GPW, this is visible in trading volume statistics: during bull markets, individual investor transaction volume increases by 200–300%. People trade more because they feel confident. Unfortunately, higher trading volume means higher costs (commissions, spreads) and statistically worse results.

Regret

"If only I had bought those shares..." – this sentence destroys more portfolios than any other. Regret over a missed opportunity leads to two harmful behaviors: revenge trading (desperate attempts to "make back" losses) and compensatory risk-taking at the next opportunity.

Emotional Attachment

Polish investors are particularly prone to emotional attachment to companies: "I buy CD Projekt because it is a Polish company that achieved international success." Investment patriotism is a beautiful idea, but your money does not distinguish between flag colors. Fundamentals either support the valuation, or they do not.

How to Tame Your Emotions – Proven Strategies

1. Automate Your Decisions

The best defense against emotions is eliminating the moment of decision. Set up standing orders – for example, every month you invest 500 PLN into an MSCI World ETF. Tools like Freenance help you monitor whether your automated investment strategy stays on track, eliminating the need to check prices daily.

This is the DCA (Dollar Cost Averaging) strategy – simple, boring, and remarkably effective. You invest regularly, regardless of market sentiment. When the market drops, you buy cheaper. When it rises, you buy at higher prices, but your portfolio grows regardless.

2. Keep an Investment Journal

Record every investment decision: what you are buying or selling, why, and what you feel at that moment. After a few months, you will see patterns – for example, that you always sell after a 10% drop, even though historically the market recovered those declines within a few weeks.

3. The 24-Hour Rule

Never make an investment decision on impulse. If you see an opportunity (or are panicking), wait 24 hours. In 90% of cases, the morning euphoria or evening panic will pass, and you will make a better decision.

4. A Written Investment Plan

Create a plan that clearly defines:

• Your investment horizon (e.g., 20 years until retirement)
• Your acceptable risk level (e.g., maximum drawdown of 30%)
• Rebalancing rules (e.g., once per quarter)
• Selling conditions (specific, measurable criteria – not "when I feel it is time")

When the market crashes, you do not need to make a decision – just reach for your plan.

5. Reduce Stimuli

Stop checking prices daily. Turn off push notifications from brokerage apps. Reducing short-term market exposure dramatically improves long-term results. Research shows that investors who check their portfolio once per quarter achieve better returns than those who do so daily.

6. Education as an Emotional Buffer

The better you understand markets, the less fear you feel. Knowing that 10–15% corrections happen on average every 1–2 years, and bear markets (-20% or more) every 7–10 years, helps you survive downturns. Knowing that markets have historically always recovered (though sometimes it took years) provides perspective.

Emotions and Different Asset Classes in Poland

Stocks on the GPW

The Warsaw Stock Exchange has been operating since 1991 and is still dominated by emotional investors. Trading volumes rise in bull markets and fall in bear markets – which is the exact opposite of rational behavior. This is particularly visible in the small-cap segment (NewConnect), where emotions can drive prices up 1,000% in a few weeks, followed by an equally spectacular crash.

Government Bonds

Paradoxically, even "safe" bonds trigger emotions. In 2022, when the RPP raised interest rates, fixed-rate bonds lost value. Many investors who had bought them as a "safe haven" panic-sold – not understanding that by holding the bond to maturity, they would receive the full principal plus interest.

Real Estate

Real estate triggers particularly strong emotions in Poles – because "bricks are safe." This belief leads to excessive concentration of wealth in a single asset class. According to NBP data, real estate accounts for over 70% of the average Polish household's net worth. That is not diversification – it is emotional attachment to one type of asset.

The Role of Technology in Managing Emotions

Modern financial management tools, such as Freenance, help separate emotions from decisions. A dashboard showing the long-term trend of your portfolio – rather than daily fluctuations – reduces exposure to panic-inducing stimuli. Automated alerts about deviations from your plan replace the constant, anxious checking of prices.

Robo-advisors, though still uncommon in Poland, go one step further – they eliminate the human factor from the decision-making process. An algorithm does not panic, does not succumb to greed, and does not read investment forums at three in the morning.

Institutional Emotions – Do Professionals Get Scared Too?

Yes. Fund managers are subject to the same emotions as individual investors, with the additional pressure of benchmark performance. The phenomenon of "herding" is well documented among professional managers – they are afraid to deviate from the index, because nobody loses their job by losing as much as the market, but many lose it by losing more.

In the Polish TFI (investment fund) market, this is visible in portfolio composition: during bull markets, most equity funds hold similar positions (the same blue chips), and during bear markets, they simultaneously increase their cash allocation. This is not independent analysis – it is emotional herd behavior with a professional label.

Summary – Emotions Are Normal, Losses Do Not Have to Be

You cannot eliminate emotions from investing – we are humans, not algorithms. But you can build systems and habits that minimize the impact of emotions on your decisions:

1. Automate – regular, systematic investing eliminates the moment of decision
2. Plan ahead – a written investment plan is your anchor in the storm
3. Reduce stimuli – less checking equals better results
4. Educate yourself – knowledge is the best emotional buffer
5. Accept your emotions – do not fight them, but do not let them make decisions for you

Markets will rise and fall. Emotions will appear. But your results depend not on what you feel, but on what you do with those emotions. And the best thing you can do is have a plan – and stick to it.
