Why your ETF looks like it beat the index — total return vs price return
Written and maintained by ETF Scanner · Report a correction
Every index has two versions: one without dividends, one with. Which one you compare against decides whether the same ETF looks like a winner or a laggard.
Every index has two versions
Index providers usually publish two series off the same constituent list. The price return (PR) version tracks price moves only; the total return (TR) version assumes every dividend paid by a constituent is reinvested back into the index.
The number quoted in the news — KOSPI at 2,500, the S&P 500 at 5,800 — is almost always the price return series. Dividends are not in it.
An ETF, meanwhile, actually receives those dividends. The cash either goes out as a distribution or is reinvested inside the fund. Either way it does not vanish.
The gap is bigger than it looks
Suppose the constituents yield 2% a year. Over one year that is a 2 percentage point difference — easy to dismiss.
Over ten years it is not. Compounding 1.02 ten times gives roughly 1.219, so price return and total return drift about 22 percentage points apart. In a higher-yielding market, or a dividend-focused fund, the gap is wider still.
So a claim like 'this ETF beat the index by more than 20% over a decade' may describe a fund that beat nothing at all. It simply collected the dividends.
Mistaking the benchmark for tracking error
A fund that pays distributions out sends the dividends away, so its price path resembles the price return index. Subtract fees and it looks like it slightly trails the index.
An accumulating (TR-type) fund keeps the dividends inside, so it steadily pulls ahead of the price return index. Reading that as skill or outperformance is a misreading — the benchmark it was built against is simply the total return series.
To judge how well a fund actually tracks, compare it against the exact index named in its documents, on a total-return basis that includes distributions.
How to compare properly
First, check whether the benchmark name ends in 'TR'. If it does, the fund is built to roll dividends up internally.
Second, when comparing two funds, confirm both figures include distributions. Putting a distribution-inclusive return next to a price-only return is not a comparison at all.
Third, in a taxable account the accumulating structure is not automatically better. Timing of distributions and the account type change the after-tax result, so treat structure and tax outcome as separate questions.
