Herd Effect: What is it, What are the Risks and How to Avoid It?

Collective behavior is fascinating and sometimes misleading in the world of finance.

The “herd effect”, a term widely used in behavioral psychology and finance, describes the tendency of people to follow the decisions of others, without critical analysis or their own evaluation of the facts.

By understanding the “herd effect,” investors can avoid dangerous traps, make more informed decisions, and mitigate risks that affect their portfolio and long-term profitability.

In this text, we will discuss the essence of this phenomenon, its risks in the financial market and practical ways to avoid it.

What is the herd effect?

The herd effect occurs when individuals, usually driven by social pressure or lack of knowledge, make investment decisions based on the actions of a larger group, instead of acting on their own.

This phenomenon is widely studied in behavioral sciences and reflects how much a group's decisions influence our own choices, even if these decisions are not based on logical or value analysis.

In the financial market, the herd effect is especially dangerous, as it can lead to dramatic fluctuations in asset prices and cause speculative bubbles or even sudden declines.

As an example, consider the cryptocurrency boom of 2017, where countless inexperienced investors bought digital assets after hearing about the high returns others were getting.

According to data from a survey by the University of Cambridge, by the end of that year, the number of digital wallet users had tripled globally.

However, most of these investors entered the market simply because “everyone was doing the same”, without considering the high volatility and risks involved.

What are the risks of the herd effect?

The herd effect can lead investors to make impulsive and ill-informed choices, often following upward or downward movements in markets that do not reflect the real fundamentals of the assets involved.

Among the most obvious risks are:

Increased Market Volatility:

Mass movements in investments can generate abrupt rises and falls in the value of assets.

When large groups of investors move in the same direction, buying or selling pressure can create temporary price fluctuations, disconnecting them from the real values of the assets.

Financial Bubbles and Crashes:

The dot-com bubble at the turn of the century is a classic example of the herd effect.

At the time, investors flocked to tech startups based on future growth potential, without a thorough feasibility analysis.

When the bubble burst in 2000, the losses were huge, with the Nasdaq index falling nearly 78% between 2000 and 2002.

Property Losses:

Following the herd can be particularly dangerous for investors. conservative profile or moderate, who tend to preserve equity in low-risk assets.

When they invest in volatile assets just because the “herd” does, these investors can suffer significant losses in times of market decline.

How to avoid the herd effect?

Decision making based on herd effect can be avoided with some simple but demanding practices.

Maintaining discipline and trusting a personal investment strategy are key to avoiding mistakes made due to impulse and social pressure.

#Financial Education and Research:

Before investing, it is essential that each investor understands the asset they are acquiring. This involves studying the company's history, future projections and associated risks.

As Warren Buffett, once mentioned: “Risk comes from not knowing what you are doing.”

Investing based on real facts and data reduces the chances of being influenced by peer pressure.

#Portfolio Diversification:

A diversified portfolio is the best way to reduce risk.

When an investor bets on different sectors and asset classes, he mitigates the losses of any specific asset, reducing the impact of a decline caused by the herd effect.

#Set Goals and Limits:

Having clarity about your financial goals prevents you from making impulsive decisions. This means setting return targets, timelines, and loss limits.

Having clear limits, such as a stop loss, is essential to avoid catastrophic losses in bubble or crash situations.

#Avoid Too Much News and Social Media:

Social media and news channels can create a sense of urgency and anxiety.

While it is important to stay informed, over-consuming news can lead investors to act impulsively.

Case study: herd effect in the 2008 crisis

The 2008 financial crisis is a perfect example of this. large-scale herd effect.

Many investors bought assets related to the US real estate market, trusting in a steady upward trend.

This behavior was encouraged by banks and financial institutions, which in turn followed market behavior.

When the housing market began to collapse, the herd effect contributed to a mass sell-off of assets, worsening the crisis and culminating in a global recession.

According to the US Institute for Economic Research, the crisis wiped out nearly $14 trillion in household wealth, with impacts lasting for years.

The role of fintechs in mitigating this effect

With the advancement of financial technology, fintechs are increasingly accessible, allowing investors to use digital platforms with high-quality data and analysis.

Investment apps like Robinhood and Nubank, democratize access to the financial market, by offering research and analysis tools that help reduce the influence of the herd effect.

Still, it is essential that users of these platforms practice personal responsibility and develop financial literacy to avoid making rash decisions.

Conclusion

O herd effect It is a common and understandable phenomenon in human behavior, but it can be harmful in the financial market.

Investing based on mass trends without critical analysis is a recipe for volatility and asset instability.

Therefore, preventing herd behavior requires a disciplined, informed and diversified approach.

In times of uncertainty, the financial education and commitment to a well-defined strategy are essential to avoid impulsive behavior.

Whether through diversification, research or monitoring tools, the investor's goal should always be to make informed decisions and avoid pressures that could lead to undesirable consequences.
