Why Should You Diversify Your Investments?
"Don't put all your eggs in one basket." Diversification is the single most effective technique to reduce investment risk without sacrificing overall long-term return potential.
Core Principle: The Only Free Lunch in Finance
Nobel laureate Harry Markowitz called diversification the only free lunch in finance because it minimizes risk without reducing expected returns.
3 Dimensions of Diversification
Across Asset Classes
Mix Equities, Debt/Bonds, Gold, Real Estate, and Cash equivalents.
Across Sectors
Spread equity holdings across Tech, Banking, Healthcare, Energy, and FMCG.
Across Geographies
Invest in international markets (US, Europe, Emerging Markets) to reduce single-country risk.
Types of Investment Risk
Systematic vs. Unsystematic Risk
-
Systematic Risk (Market Risk): Macro factors like inflation or interest rate hikes that affect all market assets. Cannot be eliminated by diversification.
-
Unsystematic Risk (Company Specific): Risks unique to a company or industry. Can be virtually eliminated through diversification!
Summary & Key Takeaways
- Diversification protects your overall portfolio when one specific sector crashes.
- Avoid over-diversification (holding 50+ stocks creates unnecessary friction and dilution).
- Index funds offer instant, low-cost diversification across hundreds of companies.
