Dividend Growth ETFs vs High-Yield ETFs: The Real Cost Behind the Advertised Returns
An ETF with a advertised yield of 8%, compared to a similar fund showing only 3.9%, appears far more attractive at first glance. This is precisely the reflex that can prove costly for Belgian investors building a dividend portfolio.
The advertised yield of an ETF is not a measure of performance: it is a ratio between a dividend paid and a stock price at a given moment. It says nothing about the sustainability of that dividend, or what will happen to the price. A high yield can signal a generous and healthy company — or a company whose stock price has collapsed, which mechanically inflates the ratio. Understanding this distinction changes how you compare two dividend ETFs.
Key takeaways
- A high yield does not signal a better company: it may simply reflect a falling stock price, according to Curvo's dividend ETF guide.
- A high payout ratio increases the risk that a dividend will be cut, not that it will be sustainably generous.
- ETFs that filter based on dividend growth history, such as "dividend aristocrats," exclude the most fragile companies rather than maximize advertised yield.
- Physical replication is preferred over synthetic replication to limit counterparty risk.
- Active funds sold by most banks generally cost more than an equivalent index ETF and deliver lower returns, according to Curvo.
Why an 8% yield can be a warning sign
A dividend yield is calculated by dividing the dividend paid by the stock price. This ratio moves both ways: a company can increase its yield by distributing more — or simply because its price has fallen. In the latter case, the market often anticipates future difficulties, including a possible dividend cut.
This is what Curvo's dividend ETF guide calls the yield trap: companies posting the highest yields are frequently those whose stock price has collapsed for fundamental reasons, not those performing best. A high yield is therefore not a sign of generosity but, often, a symptom.
The payout ratio — the share of profits returned as dividends — illuminates this mechanism. The higher this ratio, the greater the risk that a company will need to cut its dividend, according to Curvo: a company distributing nearly all its earnings has less cushion if results deteriorate.
This distinction does not mean paying a dividend is a negative signal. On the contrary: companies that regularly pay dividends are generally well-established and financially stable, implying lower risk than non-dividend payers, per Curvo. It is the level of advertised yield, not the fact of paying a dividend itself, that should raise concerns.
The quality filter: what a "dividend aristocrats" ETF changes
Rather than selecting the highest yields, some ETFs filter companies based on the consistency of their dividend policy. To be included in the S&P Global Dividend Aristocrats index, a company must have increased its dividend for at least ten consecutive years while simultaneously posting positive return on equity and operating cash flows, according to Curvo. This filter mechanically excludes companies whose dividend is recent, unstable, or financed by debt.
VanEck applies similar logic to its dividend ETFs, selecting the hundred companies paying the largest revenue streams based on dividend yield, resilience, and growth potential, according to the Morningstar Dividend Leaders index methodology described by VanEck. The VanEck Morningstar Developed Markets Dividend Leaders UCITS ETF (TDIV), which follows this methodology, is rated at risk level 4 out of 7 by VanEck — an intermediate profile, neither defensive nor speculative. This fund does not appear among the five ETFs compared in the table below, drawn from a separate sample.
According to VanEck marketing communications, this fund has paid a dividend every year since 2016, increased that amount, and 52% of the initial capital would already have been returned to investors in cash. These figures describe past performance, which is not indicative of future performance and does not constitute a guarantee that this trajectory will repeat. However, they illustrate what a methodology built around consistency rather than instantaneous yield can produce over time.
What the table reveals: high yield = high risk
Curvo's dividend ETF guide (data from February 2024) compares five dividend ETFs available to a Belgian investor. Placed side by side, advertised yield, annual cost (TER), and replication method paint the same picture.
| ETF | ISIN | Holdings | Yield | TER | Replication |
|---|---|---|---|---|---|
| Vanguard FTSE All-World High Dividend Yield | IE00B8GKDB10 | 1,855 | 3.9% | 0.29% | Physical |
| SPDR S&P Global Dividend Aristocrats | IE00B9CQXS71 | 92 | 4.3% | 0.45% | Physical |
| iShares MSCI World Quality Dividend ESG | IE00BYYHSQ67 | 182 | 2.8% | 0.38% | Physical |
| Xtrackers STOXX Global Select Dividend 100 | LU0292096186 | 100 | 8.4% | 0.50% | Synthetic |
| iShares Emerging Markets Dividend | IE00B652H904 | 105 | 8.1% | 0.65% | Physical |
The two most expensive ETFs in the table are also those posting the two highest yields. The Xtrackers combines the highest yield (8.4%) with the only synthetic replication method in the group, which exposes you to counterparty risk that physical replication avoids. The iShares Emerging Markets shows comparable yield (8.1%) but at a TER of 0.65%, the highest in the table, consistent with the generally higher cost of managing emerging market funds.
At the other end, the iShares MSCI World Quality Dividend ESG posts the lowest yield (2.8%) in the group. A more modest yield does not necessarily signal a weaker selection: it can also reflect different sector composition, distribution policy, or valuation than other funds in the table.
The hidden cost that TER doesn't show
The displayed TER does not exhaust the notion of cost. Four other elements weigh on the net return actually received by an investor.
The first is replication method. A physical replication ETF holds the stocks of the index it tracks directly; a synthetic replication ETF uses a swap agreement with a counterparty to reproduce the index's performance, a risk governed by UCITS regulation, which imposes maximum counterparty exposure and collateral requirements. Some investors, including Curvo, nonetheless prefer physical replication to limit this third-party risk — a preference that is not absolute consensus and does not appear in any TER.
The second is fund size. For a Belgian investor, a minimum size of around 100 million euros in assets under management provides a reasonable benchmark, according to Curvo, alongside a low TER, physical replication, and domicile in Ireland or Luxembourg. A fund that is too small exposes you more to closure risk or reduced liquidity.
The third concerns comparison with the most widespread alternative in Belgium: active funds offered by most banks. These funds are much more expensive and deliver less than an ETF that simply tracks an index, per Curvo — a cost gap that accumulates every year, unlike the TER of an index ETF which remains stable and public.
A final friction mechanism concerns reinvestment. In an accumulating ETF, the dividend is automatically reinvested, avoiding the fees and procedures that manual reinvestment would entail, according to Curvo. In Belgium, the 30% withholding tax on dividends applies equally to individual stocks and distributing ETFs — a clarification of context reminding us that the gross yield displayed is never the net amount a Belgian investor actually receives.
The first 833 euros in dividends from individual stocks are legally exempt from tax. However, this exemption does not apply to dividends paid by funds or ETFs: an investor holding a distributing ETF cannot benefit from it on this portion, according to Curvo. This is an additional tax advantage of accumulating ETFs, which escape this tax entirely since the dividend is reinvested before reaching the investor's bank account rather than distributed — an argument that adds, from a purely tax standpoint, to the generally favored preference for accumulating funds in Belgium.
From January 1, 2026, a 10% tax applies moreover to capital gains realized on this type of asset, with an annual exemption of 10,000 euros per taxpayer; for assets acquired before this date, their value on December 31, 2025 serves as the reference for calculating taxable gains. This factor, separate from dividend withholding, adds to the calculation of the final net return of a dividend ETF. Its practical implementation, as well as its interaction with other taxes applicable to certain funds, including the so-called Reynders tax, remains still being clarified: better to consider this aspect as evolving rather than definitively settled.
