Easy to trade - You can trade ETFs easily on the SEHK during its trading hours through a broker or a bank dealing in securities.
Diversification - Usually, an ETF invests in dozens of securities. This spreads the risk. By investing in a passive ETF, you may gain exposure to the underlying index without the expense of buying all the underlying index constituents yourself.
Transparency - Trading information of an ETF is easily accessible on a real-time basis.
Cost effectiveness - Trading ETFs on the SEHK does not incur subscription or redemption fees, although transaction costs such as brokerage commissions still apply. Investors should check the fees with the intermediaries (e.g. banks and brokerage houses) as different firms would have different fee level/structure, e.g. some may charge a minimum brokerage fee.
