Every few years, a sector gets hot — IT in 2020-21, PSU banks and defence in 2023-24, pharma before that. Fund houses launch NFOs (new fund offers) riding that excitement, and investors pile in near the top. Understanding what these funds actually are helps you avoid becoming that statistic.
| Sectoral Fund | Thematic Fund | |
|---|---|---|
| Scope | One industry (banking, IT, pharma, auto) | One idea across several sectors (infra, consumption, ESG, digital) |
| SEBI minimum in theme | 80% of assets | 80% of assets |
| Diversification within | Very low | Slightly better — spans multiple industries |
| Typical volatility | Very high | High |
| Best suited for | Investors with a strong, informed view on that sector | Investors betting on a long economic trend |
A diversified equity fund might hold 40-60 stocks across a dozen sectors. If one sector has a bad year, the others absorb the hit. A sectoral fund has no such shock absorber — every holding is exposed to the same set of risks: government policy, global commodity prices, interest rate cycles, or a single regulatory change. That's why sector funds can top the charts one year and sit at the bottom the next. It's the same concentration that creates the upside that also creates the downside.
Sectoral and thematic NFOs are usually launched after a sector has already run up — fund houses time launches to investor excitement, not to opportunity. By the time a "hot theme" fund is being marketed heavily, a large part of the easy gain may already be behind it. Before investing in any theme, check where the sector's valuations stand relative to its own history, not just how good the news sounds.
Think of your portfolio in two parts — a core (diversified, flexi-cap, large-cap, or index-style funds that quietly compound over decades) and a satellite (smaller, higher-conviction bets, sectoral and thematic funds included). The core should carry 80-90%+ of your equity money. The satellite is where you can afford to be wrong. If you'd like a primer on building that core first, see our guide on how to choose a mutual fund and on comparing large-cap, mid-cap, and small-cap funds.
Sectoral and thematic funds aren't bad products — they're specialised tools. Used in small doses, with a real view and a long horizon, they can add spice to a portfolio. Used as a core holding, or bought because a theme is trending, they turn your investing into speculation with extra steps. Know which one you're doing.
