Home Bias is the empirical tendency of investors to over-allocate their portfolios to their domestic country's equities, far above the country's weight in global market cap, despite the diversification benefits of international investing. It is observed across virtually every country and investor type studied.
The math behind it: India is approximately 4% of global equity market cap (MSCI ACWI weights, recent data). A globally-diversified portfolio would therefore hold ~4% India and ~96% rest-of-world. In practice, most Indian retail investors hold 95-100% Indian equities — a ~24x overweight to home.
Why investors exhibit home bias:
- Familiarity: Investors believe they "know" domestic companies better.
- Currency and capital-control friction: The LRS route caps outbound flows at USD 250,000 / person / year.
- Tax complexity: Foreign holdings require Schedule FA reporting; capital gains are non-LTCG-friendly.
- Information asymmetry: Indian news and TV cover Sensex / Nifty, not S&P 500 or MSCI Europe.
Example: An investor with a Rs 1 crore portfolio holds 100% Indian equity. In 2020 the rupee depreciated 4% against the USD, and Indian equities returned 15% in INR vs 18% for S&P 500 in INR (after FX adjustment). A 70/30 India/US split would have produced 15.9% with materially lower drawdown (lower correlation between assets).
Costs of excessive home bias:
- Concentration risk in a single economy's policy, monsoon, and political cycle.
- Reduced diversification across innovation themes (US tech, Chinese consumer, European luxury).
- Missed rupee-hedge during INR depreciation phases.
How to address:
- Use international fund-of-funds (US equity, NASDAQ 100, MSCI World) via Indian AMCs to avoid LRS friction (though these have their own caps when SEBI tightens).
- Allocate 10-25% of equity to global — a sensible compromise between pure-home and full-global.
- Diversify within India across market caps and sectors to mitigate single-economy risk.
