Exchange-traded funds combine the diversification of a fund with the tradability of a stock. That simple combination has made ETFs one of the most important instruments in modern portfolio construction.
What an ETF actually is
An ETF is a fund that holds a basket of securities and trades on an exchange throughout the day at market prices. Most track an index; some follow factor strategies, sectors, commodities or bonds. Creation and redemption mechanisms help keep market prices close to the fund's net asset value.
Why investors use them
Diversification in a single trade, typically low expense ratios, intraday liquidity and tax-efficient structures are the core attractions. A broad-market ETF can spread exposure across hundreds of companies in one position.
What to check before investing
Expense ratio, underlying index methodology, tracking difference, average spread, assets and trading volume all matter. Two ETFs with similar names can hold meaningfully different portfolios.
