Exchange Traded Funds (ETFs) are passively or actively managed and open-ended funds. ETFs can be broadly grouped into two types: Physical ETFs and Synthetic ETFs. All listed ETFs on the HKEX securities market are authorised by the Securities and Futures Commission as collective investment schemes. Similar to other securities, investors can buy or sell ETFs through their brokers anytime during the securities market’s trading hours. ETFs are designed to track the performance of their underlying benchmarks and offer investors an efficient way to obtain cost-effective exposure to a wide range of underlying market themes.——Reference from HKEX
