Was planning to compare which broker to invest in HK/China when I saw that OCBC is launching a Hang Seng Tech ETF! What are your thoughts on going for this as opposed to doing so directly?

It depends on which exchange you like to deal in and expense ratio of the etf. Like ishareshstech (03067) on HK exchange.

Yes. I will go for this cause easier since its in sgd. No need to convert and hold so many currencies
