Understanding Herd Mentality: Why Investors Follow the Crowd

Investing frequently entails being a part of a flock, all positioned in the same direction. This group mentality is defined as a herd mentality. Herd mentality happens when an individual is persuaded to follow someone else's lead rather than thinking or determining the action themselves. At the heart of herd mentality is FOMO, which stands for the fear of missing out. FOMO can trigger investment decisions that are reckless, however, a lot of the time these impulsive decisions can have significant repercussions and loss of money. By understanding herd mentality and the associated triggers, it becomes easier for investors to identify this behavior, avoid it, or act more deliberately with investment choices. 

What is FOMO?

FOMO is a significant and powerful emotion from an investment perspective. It can be triggered by observing others profiting, and you may feel left out. These anxieties can be stimulated by social media, news headlines, movement of stock prices, or seeing more comments about a particular stock to potentially move the stock price. FOMO can typically create a vibe where irrational investing behavior occurs in normally sane investors. Individuals often jump in on a trend without conducting any due diligence in hopes of attaining success. However, chasing market trends based on popularity rather than on investment fundamentals will often backfire for investors with unfortunate outcomes. Identifying and recognizing FOMO and then dialling down the urge of acting impulsively is a very important key to investment success.

Some psychological triggers behind herd mentality 

• Social Proof in Investing

Social proof is the natural inclination to imitate the behavior of others, especially when faced with uncertainty. In terms of investing, when we see other investors buying a certain stock or asset, we subconsciously assume them to have knowledge we might not possess. This sense of validation encourages us to act accordingly since we believe we are asserting a safer choice. However, such behavior can cause asset prices to rise above their real, actual value. 

• Emotional Investing vs. Logical Investing 

Emotions often override logic when money is involved. Emotional investing is when we let excitement, fear, and/or greed inspire our decisions. Conversely, logical investing means spending time analyzing and planning our moves. Those who are influenced by the herd mentality typically act emotionally by buying high and selling low. Understanding the difference may save prospective investors from making themselves an expensive mistake.

Lessons from Past Market Bubbles

• The Dot-Com Bubble

Throughout the late 1990s, technology firms became fashionable. Investors invested (or planned to invest) in technology start-ups, many of which had negligible or no revenue streams. The fear of missing out on the "next big thing" created irrational prices for these stocks. When reality struck, the dot-com bubble burst, wiping tens of billions off the value of those companies, which in turn affected the stock market. 

• The 2008 Financial Crisis

The housing market boom leading up to 2008 created a feeling of collective invulnerability. It seemed everyone was buying real estate either for themselves or by investing, all because of easy credit. The herd mentality contributed to risk-taking investments in over-leveraged positions in the housing market and ultimately created a massive historical debacle.

• The GameStop Short Squeeze

In early 2021, retail investors on Reddit coordinated to buy stock in GameStop, causing prices to increase dramatically. The entire mania was driven largely by social media provocations and FOMO. There were some investors who sold at appropriate times and profited; however, most investors who bought near the peak price incurred severe losses.

How FOMO Influences Market Trends Today 

• Role of Social Media in Fueling Investment Trends and Market Volatility

Websites like Reddit, Twitter, and TikTok play an influential role in disseminating investment news and hype. Viral posts can quickly result in mass buying or selling and further feed into individual and collective herd mentality. Retail and amateur investors can be misled and distracted by excitement, noise, and exaggerations while separating out their next best investment opportunity.

• Meme Stocks & Crypto Mania

Meme-based stocks and cryptocurrencies have all surged in marketplaces due to perceptions and the presence of FOMO. Just look at the extreme surge in Dogecoin or Gamestop, driven not by fundamentals but by unique public excitement and attention. Early players profited, while latecomers were left holding losses.

The Risks of Herd Mentality

• Market Mispricing and Bubble Patterns

When prices are driven by euphoria and not intrinsic value, bubbles form, and the bubbles eventually burst into steep corrections—the investors who followed the herd, without engaging in critical thinking, often suffer the most.

• Panic Selling

Herd mentality does not only cause buying frenzies; it also leads to panic selling. When the market experiences a downturn, levels of fear spread quickly and create mass exiting of sales. This type of behavior locks-in losses and further adds volatility to the market.

How to Identify Herd Mentality in Real Time & Protect Your Investments

• Monitoring Market Sentiment Indicators

  Savvy investors turn to sentiment indicators to determine the market’s emotional state. Indicators such as the Fear & Greed Index, put/call ratios, and social media tracking can help you determine when the markets are excessively exuberant or fearful. The ability to isolate and detect extremes of emotion, between extreme vitality and fear, is extremely important to keep yourself on a balanced path of investing.

  
  

• Recognizing Market Bubbles Before They Burst

  Market bubbles display predictable signs—price spikes solely with no justifiable rationale in earnings or other fundamentals, too much attention from media outlets, and too much interest from investors demonstrating too much excitement. If your investment decisions are becoming heavily weighted and more dependent upon headlines or (social) media attention rather than directly on relevant research, take note that you could be falling into herd mentality.

How to Avoid Falling Victim to FOMO

• Developing a Long-Term Investment Strategy

  Long-term investing is about steady growth, diversification, and saving with discipline. Having clear investment goals will help to anchor you so that you might be less vulnerable to getting caught up in short-term mania in the market. Sticking with your plan, rebalancing periodically, and avoiding being tempted to follow the latest trends will all support a long-term investment plan.

  
  

• Practicing Mindful Investing

  Mindful investing is about taking a pause before acting and asking if your decision is driven by emotion or if it makes sense rationally. Mindful investing is about ignoring the distractions, doing your own research, and using trusted financial resources to guide your investment decisions. The more you stay grounded and present, the less likely you are to make a decision based on the herd mentality.
