Exchange Traded Funds(ETF) possess the liquidity and convenience of stocks, as well as the investment diversification and compliance rules of mutual funds, making them highly sought after by global investors, starting to include ETFs in their investment portfolios in order to achieve the goal of allocating assets and diversifying investment risks. ETFs are managed passively. They are funds tracking changes in underlying indices and listed on stock exchanges. Because the purpose of ETFs is to “track underlying indices,” the Trustor buys ETFs to obtain a rate of return similar to changes in underlying indices.
