Hong KongMutual funds and ETFs: the differences that matter to a plan
Mutual funds price once daily at net asset value and can distribute capital gains to all holders. ETFs trade throughout the day at market prices and are generally more tax efficient because of the in-kind creation and redemption mechanism.
Same underlying holdings, different wrappers, and the differences that matter are tax and cost rather than performance.
| Mutual fund | ETF | |
|---|---|---|
| Pricing | Once daily at net asset value | Continuously at market price |
| Trading | With the fund, at the close | On an exchange, intraday |
| Minimums | Often imposed | One share |
| Tax efficiency | Lower - gains can be distributed | Higher - in-kind redemption |
| Automatic investing | Straightforward | Less so |
| Fractional shares | Standard | Platform dependent |
| Bid-ask spread | None | Yes |
| Premium or discount to NAV | No | Possible, usually small |
The tax point
This is the substantive difference and it is examined.
A mutual fund meeting redemptions may have to sell holdings, realizing gains distributed to everyone still in the fund - including someone who bought last month and has no gain of their own. That is the distribution problem.
An ETF handles redemptions in kind through authorized participants, which generally avoids realizing gains inside the fund. Investors realize gains when they sell their own shares, and not before.
Purchasing a mutual fund just before a capital gain distribution means receiving taxable income representing gains you did not participate in, with the share price falling by the distribution. In a taxable account, check the distribution date before buying.
Where a mutual fund is still right
- Inside a retirement account, where the tax difference is irrelevant.
- For automatic recurring contributions of fixed dollar amounts.
- Where the specific strategy is only available in that wrapper.
- Where a platform charges commission on ETF trades and not on funds.
The first is the big one. In a 401(k) or an IRA, the tax efficiency argument disappears entirely and the decision comes down to cost and availability.
Share classes
A shares carry a front-end load. B shares a contingent deferred sales charge falling over time. C shares a level load with higher ongoing expenses. No-load funds carry none.
Breakpoints reduce the front-end load at investment thresholds, and a letter of intent or rights of accumulation can secure a breakpoint. Failing to use an available breakpoint is a suitability problem, not merely an oversight.
Closed-end funds
A fixed number of shares trading on an exchange, often at a persistent premium or discount to net asset value. Unlike an ETF, there is no creation and redemption mechanism to close the gap.
That distinction is the one questions use to separate the three wrappers.
Dollar limits and rate thresholds here are indexed annually. Confirm the current figure before relying on it, and expect the exam to test the rule rather than the number.
Common questions
Why are ETFs more tax efficient than mutual funds?
Redemptions are handled in kind through authorized participants, which generally avoids realizing gains inside the fund. A mutual fund may have to sell holdings and distribute gains to all remaining holders.
What is buying a distribution?
Purchasing a mutual fund shortly before a capital gain distribution, receiving taxable income for gains you did not participate in while the share price falls by the distribution amount.
When is a mutual fund the better choice?
Inside a retirement account where tax efficiency is irrelevant, for automatic fixed-dollar contributions, where the strategy is only available in that wrapper, or where the platform prices funds more favourably.
What are mutual fund share classes?
A shares carry a front-end load, B shares a deferred charge falling over time, C shares a level load with higher ongoing expenses, and no-load funds carry none.
How does a closed-end fund differ from an ETF?
A closed-end fund has a fixed share count and can trade at a persistent premium or discount, because there is no creation and redemption mechanism to close the gap to net asset value.
