Fund Structure and Investor Protection · ETFs

ETF shares trade between investors, while large institutions can create or redeem units with the fund. These connected markets help explain price alignment.

Two markets serve different participants

Most investors buy ETF shares from another market participant through a broker. This is the secondary market. In the primary market, authorised participants transact directly with the fund in large creation units. A market maker may quote prices on an exchange, while an authorised participant handles creation or redemption. The same institution can perform both functions, but the roles are distinct.

Follow a creation through the system

Under an in kind creation, an authorised participant delivers an agreed basket of securities and any balancing cash, receiving ETF shares in return. A redemption reverses the process. Some funds use cash transactions or combinations instead. The fund documents determine the arrangements. An ordinary investor should not assume that a small position can be redeemed directly for the underlying securities.

Understand the economic incentive

If ETF shares trade sufficiently above the cost of acquiring the basket and completing creation, an intermediary may have an incentive to create shares and sell them. A sufficiently large discount can encourage the reverse process. Transaction costs, financing, hedging, risk limits and market access matter. The process encourages alignment but does not promise that every trade will occur exactly at NAV.

Use a realistic break even test

Suppose a creation basket costs $1 million, while the related ETF units could be sold for $1,003,000. The apparent $3,000 difference is not pure profit. If trading, hedging and processing cost $2,500, only $500 remains before other risks. A small move while assembling the basket could remove that margin. During stress or market closures, intermediaries may require greater compensation and premiums or discounts can widen.

Try it yourself

Does a daily rise in ETF trading volume necessarily mean that the fund received the same amount in new investments?

Show the worked answer

No. Secondary market shares can change hands repeatedly without creating new units. Net creations and redemptions are different from exchange turnover.
