1. What is an ETF?

An ETF is not a new legal vehicle — it is an SFC-authorised collective investment scheme (CIS) that is listed on SEHK. Most Hong Kong ETFs use a unit-trust form (an OFC umbrella is also possible since 2018), governed by s.104 SFO and the UT Code:

Framing matters: an ETF is a product form + listing status, not a legal vehicle at the same level as LPF/OFC — the trust or OFC is the vehicle; the ETF is the authorised, listed wrapper on top. LPF/OFC is a choice of legal structure; becoming an ETF is a choice of distribution (retail + real-time liquidity).

2. Chart 1: the ETF ecosystem

A trust as the vehicle, SFC authorisation, manager-plus-trustee split, PDs running primary-market creation/redemption, retail trading on the Exchange — the whole ecosystem in one view.

3. Chart 2: primary vs secondary markets

The ETF's core mechanism — why does the price stay close to NAV? Because of this arbitrage loop.

ETF primary and secondary market arbitrage loop A PD delivers a securities basket to the fund for creation units and sells them on SEHK's secondary market; when the ETF price deviates from NAV, arbitrage pulls it back — at a discount, PDs buy cheap units and redeem for the basket; at a premium, the reverse. Primary market PD broker large blocks ETF fund trust create/redeem basket→ ←units in-kind or cash exchange Secondary market SEHK exchange live trading Retail investors small lots trade price set by the market (orbits iNAV) arbitrage loop: price deviates → PD steps in → price snaps back Premium: PD creates units cheaply (delivers basket) and sells on secondary → supply rises, price falls back Discount: PD sweeps cheap units on secondary → redeems for the basket → demand rises, price recovers Chart: RegSir
Figure 2: why the ETF hugs NAV — the PD arbitrage loop is a self-correcting mechanism that needs no central counterparty.

Bottom line: choosing an ETF isn't choosing a vehicle — it's choosing distribution: you want retail investors trading live on the Exchange, so you take the s.104 + listing route. The vehicle underneath can still be a trust or an OFC; hedge-fund managers increasingly use ETFs as liquidity wrappers.

8. FAQ

Is an ETF a company or a partnership?

Neither — an ETF is an authorisation-plus-listing status: the vehicle is usually a unit trust, assets held by a trustee, decisions by a Type 9 manager. "Launching an ETF" really means "getting a vehicle authorised and then listed."

Can retail investors redeem with the fund directly?

No — primary creation/redemption is open only to participating dealers. Retail always trades on the SEHK secondary market at market prices (kept near NAV by arbitrage).

ETF vs a normal mutual fund?

A mutual fund deals daily with the fund company; an ETF trades in real time on the Exchange. Both are governed by s.104 + UT Code, but the ETF adds listing rules and a market-making layer.

Why do HK ETFs use trusts rather than companies?

Historical convention — Hong Kong retail funds have always been unit trusts; the OFC only arrived in 2018. OFC-umbrella ETFs now exist, but trust form still dominates because trusteeship is mature and familiar to investors.

What licence does the manager need?

SFC Type 9 (asset management) is the floor; the product needs s.104 authorisation. If the manager isn't licensed yet, licensing and product approval can run in parallel — but the product can't launch before authorisation.
