Definition
Sectoral ETF
A sectoral or thematic ETF tracks an index focused on a specific industry or theme, such as banking, IT or PSU stocks, giving concentrated exposure to that segment.
Indian sectoral ETFs let investors take a targeted bet on a sector like Nifty Bank, Nifty IT or PSU banks without picking individual stocks. They are useful for tactical allocation and for expressing a macro view, but concentration means they are far more volatile than a broad-market ETF.
Because they hold a narrow set of correlated stocks, sectoral ETFs offer little diversification and can swing sharply with the sector's fortunes. Capping rules apply to limit single-stock dominance, and liquidity and tracking error vary widely across products, so investors should check both before trading.
