The Three-Generation Portfolio
Grandfather Narayan’s portfolio (built in 1990s): 100% large caps – Reliance, TCS, HDFC Bank. Returns: 15% CAGR. Never lost sleep.
Father Suresh’s portfolio (built in 2010s): 50% large cap, 50% mid cap. Returns: 18% CAGR. Some volatility, but handled well.
Son Aditya’s portfolio (built in 2020): 30% large, 30% mid, 40% small cap. Returns: Varied wildly – up 80% in 2021, down 25% in 2022, up 50% in 2023.
Three generations, three approaches, three different risk-return profiles. Which is right? All of them – for the right person.
What is Market Capitalization?
Market cap is the total market value of a company’s outstanding shares.
Formula:
Market Cap = Share Price × Total Outstanding Shares
Example: Reliance Industries
- Share Price: ₹2,500
- Outstanding Shares: 676 crores
- Market Cap: ₹16,90,000 crores (~₹17 lakh crores)

Direct Stocks vs Mutual Funds by Cap
Large Cap
Mutual Fund Recommended: Hard to beat index; expense ratio low for index funds.
Mid Cap
Hybrid Approach: 50% fund, 50% direct (if you have time to research).
Small Cap
Direct Better (if you’re skilled): Fund managers hold too many stocks; concentrated bets work better in small caps.
Action Plan
For Beginners
- Start with Nifty 50 Index Fund (100%)
- Add Nifty Next 50 after 1 year
- Consider mid cap fund after 2 years
- Small cap exposure only after 3+ years of experience
For Intermediate Investors
- Review current allocation across caps
- Rebalance if any cap >50% of portfolio
- Add to underperforming cap (contrarian)
- Consider direct mid cap stocks if time permits
For Advanced Investors
- Custom allocation based on market cycle
- Direct small cap stock picking

Risk Disclaimer
Small cap and mid cap investments carry higher risk than large caps. Prices can be volatile and illiquid. Past performance doesn’t guarantee future returns. Diversification doesn’t eliminate risk. This guide is educational only. Consult a SEBI-registered advisor before investing.
