Copycat Investing in the Stock Market: Why Blindly Following Big Investors Can Be Risky

Many new investors entering the stock market look for a shortcut. Instead of studying companies, analysing financial results and understanding valuations, they may simply track what famous investors are buying and purchase the same stocks.

The idea sounds logical: if a successful investor has already done the research, why not copy the portfolio?

This approach, often called copycat investing or portfolio cloning, can be useful as a starting point for research. But blindly copying another investor's portfolio can be risky. Public information may arrive late, the stock price may have already moved, and the investor being copied may have a completely different financial situation, risk appetite and investment horizon.

For retail investors, the smarter approach is not to copy a stock purchase blindly, but to ask one important question: Why did that investor buy it?

What Is Copycat Investing?

Copycat investing means selecting stocks by following the publicly disclosed holdings or transactions of well-known investors, fund managers or other market participants.

Indian investors often track the portfolios of prominent names such as Rakesh Jhunjhunwala's estate and investment vehicles, Vijay Kedia or Ashish Kacholia. These disclosures can provide useful investment ideas, particularly for discovering companies that may otherwise have escaped an investor's attention.

However, a disclosed holding does not automatically mean the stock is suitable for everyone.

A portfolio is the result of an individual's own research, entry price, investment horizon, capital size and risk tolerance. Copying only the final stock name while ignoring those factors can lead to a very different outcome.

SEBI itself advises investors not to base investment decisions on hot tips and to exercise due diligence before investing in the securities market.

The Biggest Problem: You May Be Getting the Information Too Late

Timing is one of the biggest risks in copycat investing.

Suppose an experienced investor accumulated a stock at ₹100. By the time their holding becomes visible through a regulatory disclosure or other public information, the stock may already be trading at ₹150 or ₹200.

The famous investor may still have a comfortable profit and a strong margin of safety—the difference between what they paid and what they believe the business is worth. A new investor entering later may have neither.

This does not mean the stock is automatically a bad investment. It means the investment thesis must be reassessed at the current price.

A good company purchased at an unreasonable valuation can still produce poor returns.

You Can See the Entry, but Not Always the Full Strategy

Public disclosures rarely provide the complete investment playbook.

A large investor may:

• Buy shares gradually over several months.

• Hold the stock through sharp declines.

• Use a small position as an experimental investment.

• Own the stock as part of a broader diversified portfolio.

• Reduce or exit a position before a retail investor fully understands the change.

Retail investors who simply copy a name may not know the original entry price, the target allocation or the conditions under which the investor would sell.

This creates an information gap.

Following a successful investor is therefore very different from understanding their strategy.

Risk Capacity Is Different for Every Investor

A wealthy investor may be able to tolerate a temporary ₹1 crore or ₹10 crore decline because the position represents only a small portion of their total assets.

For a retail investor, putting a large percentage of savings into the same stock could create a completely different level of financial risk.

Investment decisions should depend on factors such as:

• Income stability

• Emergency savings

• Financial goals

• Investment horizon

• Existing assets

• Ability to tolerate losses

Research on personal portfolios also highlights that copying another person's investment choices can ignore important differences in individual financial circumstances and time horizons.

The same stock can therefore be reasonable for one investor and unsuitable for another.

Famous Investors Can Also Be Wrong

One of the most dangerous assumptions in the market is that a successful investor cannot make mistakes.

Every investor has losing positions.

Even the best investors operate with uncertainty. Their portfolios may contain companies that underperform, sectors that fall out of favour or investments based on assumptions that later prove incorrect.

The difference is that experienced investors usually have a process for managing risk. They may diversify, reassess the business or accept that an investment thesis has failed.

A copycat investor who buys only because a famous name owns the stock may not know what to do when the price falls 20%, 30% or more.

That can turn an investment decision into an emotional one.

The Smarter Approach: Use Big Investors as an Idea Generator

Copycat investing does not have to be completely avoided.

The better strategy is smart copycat investing: use a respected investor's portfolio as a source of research ideas rather than as a ready-made shopping list.

If a well-known investor owns a company, start your own investigation.

Ask:

Why might the investor have bought this company?

Study the business model. Understand what the company sells, who its customers are and what gives it a competitive advantage.

Are sales and profits growing?

Look beyond the share price. Revenue growth, profit trends and operating performance can help investors understand whether the underlying business is improving.

How much debt does the company have?

High debt can create additional risk, especially when interest rates rise or business conditions weaken.

What is the current valuation?

The reason an investor bought a stock months earlier may no longer apply at today's market price.

How large is the position?

A holding may represent a major conviction bet or only a small portion of the investor's portfolio. That distinction matters.

The Securities and Exchange Board of India's investor education material also emphasises research, diversification and understanding the securities market rather than relying on rumours or tips.

Watch Out for Herd Mentality and FOMO

Copycat investing can become particularly dangerous when social media amplifies the idea.

A famous investor's name appears beside a stock, the news spreads across YouTube, Telegram, X or other platforms, and retail investors rush to buy because they fear missing the next big rally.

This behaviour is closely linked to herd mentality and FOMO, or fear of missing out.

The National Institute of Securities Markets has highlighted how herd behaviour, social-media influence and overconfidence can encourage inexperienced investors to chase speculative opportunities rather than conduct proper analysis.

Popularity is not the same as investment quality.

In fact, when too many investors rush into the same trade, valuations and volatility can become additional risks.

A Simple Framework Before Buying a “Copied” Stock

Before investing in a stock discovered through a famous investor's portfolio, consider this five-step process:

1. Find the original idea
Use the portfolio disclosure to identify the company.

2. Understand the business
Learn how the company earns money and what could drive or damage future growth.

3. Check the financial numbers
Review revenue, profits, debt, cash flow and other relevant financial indicators.

4. Evaluate the price
Ask whether the current valuation still leaves room for potential returns.

5. Decide your own allocation
Your investment size should depend on your own financial situation—not the size of someone else's portfolio.

This approach requires more effort than simply copying a ticker symbol. But investing without understanding what you own can create much greater risk.

The Bottom Line

Copycat investing can help investors discover new companies and understand how experienced market participants think. The problem begins when imitation replaces independent research.

The stock that looks attractive in a famous investor's portfolio may have been purchased at a much lower price, as part of a larger strategy, or for reasons that no longer apply today.

The smarter approach is simple: copy the research process, not just the stock name.

Use prominent investors' portfolios as a starting point, study the business independently and make decisions based on your own goals, risk capacity and investment horizon.
