Since the first American Exchange Traded Fund (ETF) was launched in 1993, the development of ETF has come a long way.
An ETF is a collection of stocks or bonds that may be purchased for one price. Unlike mutual funds, ETFs may be bought and sold during the entire trading day just like a stocks on an exchange. Many popular ETFs track well-known stock indexes like the S&P 500. Nowadays, investors are generally aware that ETF is an indispensable financial tool. As of the end of October 2020, the amount of index products worldwide is about $10 trillion, and it is estimated that it will exceed $12 trillion by 2023.
There are several differences between ETFs and mutual funds. Whereas mutual funds tend to have human mutual fund managers who actively trade stocks in and out of the fund based on which ones they predict will go up or down, the vast majority of ETFs are unmanaged by humans.
