Herd mentality

Herd mentality is the urge to do what everyone else is doing, especially with money. It feels safer to be wrong with the crowd than right alone. The result: investors systematically buy at peaks and sell at troughs.

Biological roots

Herd behaviour kept our ancestors alive. If everyone was running from a sound, you ran first and asked questions later. The brain still operates this way, even when applied to mutual funds.

Financial bubbles ARE herd mentality

Every bubble follows the same pattern:

1. Early adopters buy a real innovation (internet stocks 1995, crypto 2017)

2. Asset rises. Early adopters look smart

3. Mainstream press notices

4. Friends and family invest because 'everyone is making money'

5. New entrants chase prices higher with no analysis

6. Asset becomes massively overvalued

7. First sellers create momentum reversal

8. Panic selling, asset falls 80-95%

Indian examples

• 2017 small cap mania: friends 'making 100%' in 6 months. Retail piled in. Then 2018-2019 small cap crash wiped out 50%.
• 2020-2021 IPO mania: 'every IPO doubles on listing'. Retail applied with leverage. Many fell 50%+ within a year.
• 2022-2023 Adani: market cap doubled to ₹20 lakh crore in months on FOMO. Hindenburg report triggered 60-75% falls.

The contrarian playbook

When the news is uniformly bullish and everyone is buying, be cautious.

When the news is uniformly bearish and everyone is selling, look for opportunity.

This doesn't mean be reflexively contrarian. It means: don't extrapolate the consensus into the future.

Defeating herd mentality

1. Define your strategy BEFORE entering markets. Don't change it based on what's popular

2. Mute social media during high-emotion market periods

3. Use SIPs (mechanical investing) to remove daily decision pressure

4. Periodically check yourself: 'Am I doing this because of analysis or because of what others are doing?'

5. Read history of bubbles and crashes. They all look obvious in hindsight, never in the moment

Takeaway. Herd mentality drives investors to buy at peaks and sell at troughs. The opposite of optimal. Every financial bubble follows the same psychological pattern. Defeat with pre-defined strategy, muted media, and historical perspective. Be cautious when the crowd is euphoric.
