- Sectoral and thematic index funds delivered returns of up to 22% over six months on NSE Indices TRI data, drawing retail investors looking past muted broad-market returns, per the article.
- These passive funds carry base expense ratios of roughly 0.14% to 0.50% and replicate sector- or theme-specific indices spanning banks, metals, energy, chemicals, defence, and capital markets.
- Anubhav Srivastava, partner and fund manager at Infinity Alternatives, said sectoral ETFs and index funds suit investors wanting sector exposure without taking on fund-manager risk.
- Nifty India Defence was nearly 40% concentrated in Hindustan Aeronautics and Bharat Electronics alone as of 30 June 2026, illustrating the high stock-concentration risk in sectoral indices.
- Most sectoral and thematic indices hold a limited number of stocks: Nifty IT, Nifty Realty, and Nifty Private Bank have 10 each; Nifty Bank has 14; Nifty Auto and Nifty Metal have 15 each; Nifty India Defence holds 19.
- Anish Teli, managing partner at QED Capital Advisors, recommended treating these funds as tactical allocations and capping exposure at 15-20% of the overall portfolio, warning against spreading across too many themes.
- New fund offers are frequently launched when a sector is already popular and valuations stretched, making tracking error and tracking difference key checks before investing.
Why it matters: The 22% headline return is real but comes with structural concentration — HAL and BEL alone made up roughly 40% of Nifty India Defence as of 30 June 2026 — and Srivastava and Teli both frame these as tactical 15-20% portfolio slices, not core holdings, meaning recent outperformance can reverse sharply once a sector cycle turns.
