JAKARTA – The majority of investors in capital markets frequently experience significant losses, not solely due to market fluctuations, but primarily because of fatal emotional decisions. Financial experts highlight that many individuals, both novices and seasoned professionals, tend to make recurring mistakes that erode the value of their investments. This phenomenon has garnered serious attention amidst the dynamic global markets of 2026, prompting a deep evaluation of investment behavior.
According to several leading financial analysts, this pattern of losses generally stems from overreactions to price movements. When markets are volatile, for instance, fear and greed often prompt investors to buy at peak prices or sell when prices plummet sharply. Such impulsive reactions rarely yield positive results and, in fact, become the primary cause of depleted investment portfolios.
Professor of Economics from Gadjah Mada University, Dr. Surya Wijaya, stated, Many investors fail to understand that capital markets are both psychological and economic arenas. The failure to manage emotions represents the biggest vulnerability exploited by market volatility. Historical data shows that those who are disciplined and rational tend to achieve long-term gains.
Common mistakes frequently made by investors include:
- Not having a clear investment strategy.
- Panicking during market corrections and selling quality stocks.
- Overconfidence during bullish markets, leading to high-risk asset purchases.
- Neglecting portfolio diversification.
- Investing based on rumors or unverified advice.
- Failing to conduct in-depth research on purchased assets.
One crucial aspect is the tendency to follow the herd mentality. When many people rush to buy a particular stock, other investors are tempted without considering the company's fundamentals. Similarly, during mass sell-offs, fear becomes contagious, driving similar decisions that often prove detrimental.
Investment strategy expert from Capital Insight Group, Budi Santoso, emphasized the importance of having a well-thought-out plan before entering the market. Every investor must have clear goals, measured risk tolerance, and an exit strategy. Without these, they are like a ship without a captain in a storm, he remarked.
To avoid these emotional traps, experts recommend several actionable tricks. First, set long-term investment goals and adhere to that plan. Do not let daily fluctuations derail your broader vision.
Second, conduct independent research. Understand the fundamentals of the company or asset you intend to buy. Do not be easily swayed by sensational news or public opinion.
Third, diversify your portfolio. Spread investments across various asset classes or industry sectors to mitigate risk. This helps protect your portfolio if one investment underperforms.
Fourth, utilize automated order features like stop-loss and take-profit. These tools help manage risk and ensure you take profits or limit losses according to your plan, without emotional intervention at critical moments.
Fifth, practice dollar-cost averaging. By investing a fixed amount regularly, you will buy more units when prices are low and fewer units when prices are high, averaging down your acquisition cost over time.
Implementing this investment discipline not only protects capital from unnecessary losses but also has the potential to significantly enhance portfolio performance in the long run. Investors who can control themselves from emotional impulses will possess a substantial competitive advantage.
Editorial Insight:
The phenomenon of investors losing money due to emotional decisions is not new, but its relevance continues to grow amidst the global market volatility of 2026. Comprehensive financial education and building investor mental resilience are key. Regulators and financial institutions need to play a more active role in providing transparent information and promoting healthy investment practices to maintain stability and trust in capital markets. Without continuous educational intervention, this cycle of emotion-driven losses will persist, hindering the potential for economic growth through capital markets.
