Managed Funds vs DIY ETFs

A managed fund has one job: beat the index by more than it charges. Most do not. Here is how to check, using the numbers the fund itself publishes.

The test in one line: take the fund's return, subtract the index return, and compare what is left to the fee. If the remainder is smaller than the fee, you are paying for the index — and you can buy the index yourself for a fraction of the price.

1 · A real factsheet, read properly

What follows are the published figures of a large, respected, actively managed balanced fund — roughly two-thirds equities, one-third bonds, over fifteen years old, with billions under management. It is not a fringe product. The fund publishes all of this honestly in its own monthly factsheet.

Read the last row again. Over its entire life the fund beat its index by 0.30% per year. The fee is 1.07% per year. The manager's stock-picking added three tenths of a percent annually and charged more than three times that for the privilege. Over one, three and five years, the fund did not beat the index at all.

2 · What the fee actually costs you

A percentage sounds small. Compounded over an investing lifetime it is not. On $100,000 growing at 8% before fees:

20 years$457,500$381,900$75,800
30 years$978,600$746,400$232,300
Nearly a quarter of the final balance goes to the manager over thirty years — and that is assuming the manager matches the index exactly. In the example above they trailed it over every period shorter than fifteen years.

3 · The fee is charged whether they win or lose

This is the part that deserves the most attention. The fee is a percentage of your assets, not of the value added. It is deducted in bad years as well as good, in years the manager beats the index and in years they trail it badly.

In the example, the one-year shortfall against the index was 4.95 percentage points. The investor still paid 1.07%. There is no refund for underperformance, and no year in which the fee is waived because the manager got it wrong.

THE ETF

4 · Survivorship — the funds you never see

Published performance tables have a quiet bias: they show the funds that still exist. Funds that perform badly are routinely closed or merged into better-performing siblings, and their records disappear from the average.

This means the industry-wide numbers you read are flattered. The true average includes the failures, and you cannot see them. When you choose a fund today, you are choosing from a list that has already had its losers removed — which tells you nothing about whether this fund will be on next decade's list.

Note the asymmetry. A broad index fund cannot be liquidated for underperformance, because it is not trying to outperform. It simply holds the market. Its survival does not depend on a manager's run of good calls.

How many actually disappear

This is not a rhetorical device. The attrition rate is measured, published, and larger than most investors expect.

Read that first number again. Start with 100 US stock funds and hold them for twenty years, and roughly 64 of them no longer exist by the end. You did not pick badly — you picked from a list where two thirds of the entries were eventually deleted. The brochure you read at the start showed none of that.

Why they close

Funds are rarely closed because something dramatic happened. The usual pattern is mundane and self-reinforcing:

Roughly a fifth of closures are mergers rather than outright liquidations. The distinction matters to the fund company more than to you: a merger keeps the assets, and the fee income, while the losing track record disappears.

What it costs the investor. A liquidation can hand you an unexpected tax bill and the job of reinvesting the proceeds. A merger can leave you holding a strategy you never chose — there is no rule requiring the new fund to pursue the same objective as the one you bought.
iSource (II) — where these figures come from

S&P Dow Jones Indices — SPIVA scorecards. US year-end 2024: 64% of domestic stock funds merged or liquidated over 20 years. Australia year-end 2025: 52% gone over 15 years, roughly 4% liquidated in a single year.

Morningstar — Why Funds Die and subsequent analysis. Average lifespan of 8.3 years among funds that closed within a 20-year high-yield cohort; closures associated with short lives, low assets under management, high fees and poor performance.

Dimensional — Mergers & Liquidations. Around 22% of closures were mergers rather than liquidations; close to two thirds of closed funds had underperformed their category average beforehand.

5 · What you are actually buying

Look at what sits inside the fund. In the example, the largest equity positions are the same mega-cap names that dominate every global index — the biggest single holding was 1.21% of the fund. A portfolio whose top holding is barely one percent is, mathematically, close to the index by construction.

That is the trap. You are paying an active fee for a portfolio that is structurally incapable of diverging much from the benchmark. The manager cannot take a position large enough to matter without accepting career risk, so they hug the index and charge as though they had not.

6 · When a fund is genuinely worth it

The case against is strong but it is not universal. A fund earns its fee when it does something you cannot do yourself:

None of those describe a balanced fund charging over one percent to hold Microsoft, Amazon, Apple and government bonds.

7 · The DIY alternative, plainly

The same 61/39 exposure can be built with two instruments: a broad equity index fund and a broad bond fund, held in whatever ratio you choose. Total cost is typically 0.03% to 0.20% per year. Rebalancing takes minutes once a year.

You give up the manager. Given the numbers above, that is what you were paying for and not receiving.

8 · Be your own manager

There is a blunter version still. Buy the thirty companies of the Dow, roughly equal amounts of each, and then leave them alone.

What you get for that:

And the doomsday case? If all thirty of those companies went bankrupt, your managed fund would not have saved you either — the manager and their hedges would have jumped a long time before that. At that point the fee was the least of the problem.

The honest caveats, because this is not free of work. Equal weights drift apart as prices move, so an occasional trim keeps it balanced. Thirty US large-caps is not global exposure and holds no bonds. And you must actually leave it alone in a bad year — which is the part most people find hardest, and the one thing a manager genuinely does for you.

The three questions to ask any fund: What is the fee? What did you return against your own index over five and ten years? And what do you hold that the index does not? If the answer to the third is “not much”, the first two have already decided it.
