Growth in the exchange-traded fund (ETF) industry exploded since these funds were first introduced in the early 1990s. These investment vehicles are pooled securities with some similarities to mutual funds, yet distinct differences. ETFs invest in a buဣndle of assets such as stock in various companies, government bonds, or commodities. They usually track an underlying index, such as the S&P 500. Unlike mutual funds, they trade on exchanges the same way stocks do.

Investors have a wide selection of ETFs to choose from with thousands of them currently trading globally. There is no shortage of companies that offer these funds. But the largest ETF companies dominate the ETF market.
