An Exchange-Traded Fund, or ETF, is an investment fund that holds a collection of assets such as shares, bonds, or commodities and is traded on a stock exchange like a regular share. Investors can buy and sell ETFs throughout the trading day, and their price fluctuates based on supply, demand, and the value of the underlying assets.
ETFs are designed to give investors easy access to diversified portfolios without needing to buy each asset individually. They are widely used for tracking market indexes, gaining exposure to sectors, or investing in specific themes such as technology, sustainability, or international markets.
Advanced
From a technical standpoint, ETFs combine features of managed funds and shares. They are structured as open-ended funds, with market makers creating or redeeming units to keep prices close to Net Asset Value (NAV). Many ETFs are passively managed, tracking indexes, while others are actively managed to try to outperform benchmarks.
ETFs are generally more cost-effective than traditional managed funds due to lower management fees and transparency in holdings. They provide liquidity since they can be traded intraday, unlike managed funds which are priced only once per day. However, investors must also consider trading costs and potential tracking errors when evaluating performance.
