Exchange-Traded Funds (ETFs) emerged in the early 1990s, with the first, the SPDR S&P 500 ETF, launching in 1993. ETFs allowed investors to trade a diversified portfolio like stocks. Over time, their popularity surged due to low fees, tax efficiency, and flexibility. ETFs now cover a wide range of asset classes, including bonds, commodities, and international markets. https://businesssuccesselites.com/finance/evolution-of-exchange-traded-funds-etf/
