ETF
Exchange-Traded Fund
An investment fund that trades on stock exchanges like individual stocks while tracking an index, commodity, bonds, or basket of assets.
ETFs combine the diversification benefits of mutual funds with the trading flexibility of individual stocks. They typically track an underlying index, commodity, or basket of securities using either physical replication or synthetic methods. ETFs trade throughout market hours at market prices determined by supply and demand, unlike mutual funds which price once daily at net asset value. The creation and redemption mechanism with authorized participants helps keep ETF market prices close to underlying net asset value. ETFs offer cost-effective diversification, transparency, and tax efficiency compared to traditional mutual funds. They cover virtually every asset class and investment strategy, from broad market indices to specific sectors, commodities, and alternative investments.
