ETF

How it works

An Exchange-Traded Fund is a basket of securities — often mirroring an index like the Nifty 50 or Sensex — that is bought and sold on the stock exchange just like a single share. When you buy a Nifty ETF, you effectively own a tiny slice of all 50 Nifty stocks. Unlike a regular mutual fund priced once a day at NAV, an ETF's price changes throughout the trading session based on demand and supply, tracking the underlying index closely.

Why it matters

ETFs are prized for low cost and simplicity. Because most are passive (they just track an index), their expense ratios are very low compared to actively managed funds, and decades of evidence show low-cost index investing beats most active funds over the long run. They offer instant diversification and full transparency about holdings.

In India

India has a growing ETF market — index ETFs (Nifty, Sensex, Nifty Next 50), gold ETFs, sector and international ETFs, and large pools of EPFO money invested via Nifty/Sensex ETFs. You need a Demat and trading account to buy them. Gold ETFs are a popular way to hold gold without storage hassles. Tax treatment follows the underlying asset (equity ETFs taxed like equity; gold ETFs as per current rules).

Common mistakes

A key pitfall is liquidity — some Indian ETFs trade thinly, so the market price can drift away from the true value (NAV), and wide bid-ask spreads raise your cost; check liquidity and the iNAV before buying, and prefer limit orders. Investors also confuse ETFs with index *funds* — the latter need no Demat account and auto-invest via SIP, which suits many retail investors better. Choose ETFs for low-cost, liquid index exposure when you already have a Demat account and can trade with limit orders; otherwise a plain index fund delivering the same exposure via SIP is often the simpler, hassle-free route for long-term investors.
