Herd Mentality in Investing: Avoid Crowd-Driven Mistakes to Protect Wealth

Herd mentality refers to the tendency of individuals to follow the actions and decisions of a larger group, often without independent analysis. In investing, this behaviour can lead people to buy or sell assets simply because others are doing so. It ignores personal judgment and objective evaluation, causing many to enter or exit markets at the wrong time. This approach creates bubbles, sharp corrections, and heavy losses.

A Walk Through History: Famous Bubbles

Here are some notable bubbles that were caused by herd mentality:

• Tulip Mania Between 1634 and early 1637, the price of tulip bulbs, especially rare and multicoloured varieties, skyrocketed as demand surged among merchants, artisans, and even middle-class families. At its peak, a single bulb could cost more than a skilled artisan’s annual income, and some were traded for the value of a house. In today’s terms, that would be over $1 million.

The craze was fuelled by futures contracts, allowing buyers to speculate on bulbs without physical exchange. This “wind trade” created a volatile market divorced from intrinsic value. In February 1637, buyers defaulted, prices plummeted, and the market evaporated almost overnight.

• Dot-com Bubble

The Internet-based dot-com bubble occurred from 1995 to 2000. It was driven by investor optimism and easy access to venture capital. The NASDAQ Composite Index surged 400%, peaking at 5,048.62 on March 10, 2000, before crashing 76.81% to 1,139.90 by October 2002, erasing over $5 trillion in market value.

Companies like Pets.com, Webvan, and eToys.com raised millions despite lacking profits or viable business models. In 1999, 457 companies were listed on the exchange, of which 39% were related to the Internet.

The bubble burst due to overvaluation, rising interest rates, and unsustainable spending.

• 2008 Recession

The 2008 recession, triggered by the US subprime mortgage crisis, led to a global economic downturn from late 2007 to mid-2009. Global GDP growth plunged from 5.6% in 2007 to 0.1% in 2009. The US economy contracted by 2.5% in 2009, with unemployment reaching a peak of 10% in October of that year. Over 8.7 million jobs were lost in the US alone.

Global merchandise exports declined from $16.1 trillion in 2008 to $12.5 trillion in 2009, representing a 22% decrease in value. G7 nations experienced GDP shrinkage, with notable declines in Germany (-5.7%), Japan (-5.4%), the UK (-4.2%), and Italy (-5.3%). The crisis wiped out $19.2 trillion in global stock market value by March 2009.

• Game Stop Surge

In January 2021, GameStop’s stock surged over 1,500% due to a coordinated short squeeze by retail investors on Reddit’s r/WallStreetBets. While not officially labelled a scam, some experts have called it a “modified pump and dump.” The frenzy targeted hedge funds shorting the stock, causing billions in losses. Trading platforms like Robinhood restricted purchases, sparking accusations of market manipulation and unfair access. Influencers like “Roaring Kitty” played a key role, and bots may have helped amplify the hype.

How Herd Mentality Affects Your Investments

Herd mentality affects your investment in the following ways:

• Ignorance

When you follow the crowd blindly, you stop trusting your own analysis. Even if you have studied a stock well and found valid reasons to invest or avoid it, herd behaviour makes you second-guess your judgment. Over time, you start making decisions based on social pressure rather than facts.

• Wrong Timing

When many people start buying the same stock, the price typically rises rapidly. If you follow the crowd, you are likely to enter when the price is already high. At that point, there is very little room for growth. This happens because the early buyers have already booked profits, and the market is overreacting. You end up paying more for an investment that may not be worth it.

• Over exposure

When everyone around you is excited about a particular asset, you may keep increasing your exposure to it without setting proper limits. This overexposure makes your portfolio unbalanced. For example, if everyone is buying tech stocks, you might allocate a significant portion of your money to them to keep up. If that sector performs poorly, your losses will be much higher because you did not diversify.

• Overlook Long-Term Goals

You often set investment goals based on your personal financial needs and timelines. However, the herd mentality can distract you from achieving those goals. You get caught up in short-term trends and try to copy others without verifying whether those choices align with your plan.

• Missed Opportunity

While chasing popular investments, you may ignore good options that are not currently in the spotlight. These lesser-known opportunities often offer better value and growth potential. For example, you may miss stocks that are undervalued but fundamentally strong.

How to Avoid the Herd Mentality Trap

Here is how you can avoid the herd mentality:

• Always Verify Whenever you come across a popular trend or opinion, make it a habit to verify the facts behind it. Use trusted sources to cross-check the information. Ask yourself who is promoting the idea, what their motive might be, and whether there is credible evidence to support the claim.

• Avoid Social Media Social media can amplify the herd mentality by showcasing what many people think or do. But most of what you see on these platforms is curated, exaggerated, or even fake. The number of likes, shares, or comments does not mean the idea is always right. Always pause, step back, and look at the issue from different angles before forming your own opinion.

• Use Historical Examples Reflect on past events where a herd mentality led to harm. From financial bubbles to political disasters, history is replete with examples where crowds went astray. Study these events to understand how they happened, what signs were ignored, and what the outcomes were. When you apply these lessons to present-day situations, you become more alert to similar patterns. You start noticing warning signs early and develop stronger resistance to crowd influence.

• Evaluate the Business Fundamentals Before investing, verify that the company has strong earnings, low debt, and a history of consistent growth. Study its annual reports, balance sheets, and income statements. Do not rely on share price movements or online buzz. Evaluate whether the business is addressing a genuine problem and has a distinct competitive advantage. If the numbers and direction make sense over time, consider investing only then.

• Track Insider Trading Activity Monitor the buying and selling activities of company promoters and senior executives. If the people running the company are selling large amounts of their shares, it could be a signal that the company’s valuation has become unrealistic. On the other hand, when insiders are buying, it often means they believe in the future performance.

• Know the Ownership Pattern Check if large institutional investors, such as mutual funds, pension funds, or foreign institutions, hold a major stake in the company. These investors follow a rigorous research process before making a purchase. However, if their stake continues to decline quarter after quarter, take it as a warning sign. They may have found weaknesses that retail investors often miss.

Conclusion

Herd mentality in investing is more common than we realise. It is easy to follow the crowd, especially when it feels like everyone is making money or panicking together. But history shows that such behaviour often ends in losses.

Smart investors focus on facts, maintain discipline, and resist the temptation to chase trends. They understand that every person’s financial journey is different. By staying calm, informed, and independent, you can protect your money and make better choices, even when the crowd goes the other way.
