Exchange-Traded Funds (ETFs) originated in the early 1990s as a way to trade baskets of assets like stocks. They gained popularity due to their low fees, diversification, and ease of trading on stock exchanges. Over time, ETFs evolved to include a variety of asset classes, such as bonds, commodities, and sector-specific investments, making them a mainstream investment tool. https://businesssuccesselites.com/finance/evolution-of-exchange-traded-funds-etf/
