Motley Fool Capital Efficiency 100 Index ETF (TMFE)

The Motley Fool Capital Efficiency 100 Index ETF (ticker TMFE) owns one hundred large-cap American companies chosen because they convert investor capital into profits exceptionally well — the mirror to TMFC’s general-purpose stock selection, TMFE applies a more specific filter: businesses that earn outsized returns on the money invested in them.

What does capital efficiency mean, and why does it matter?

A capital-efficient company earns high returns on the money—equity and debt alike—that has been invested in it. Consider two businesses, each worth ten billion dollars. Company A invests one billion dollars in plants and equipment each year and earns two hundred million in profit—a return of twenty percent on invested capital. Company B invests five billion and earns one billion in profit—a return of twenty percent. Both have the same return on capital. But Company A did it with one-fifth the capital invested. That is capital efficiency. It is the difference between a company that prints cash and a company that swallows it.

TMFE screens for this. The index selects one hundred companies whose return on invested capital—the operating profit generated by each dollar of capital deployed—is high and durable. These are typically businesses with strong competitive moats. A software company with a recurring subscription and minimal marginal costs. A consumer brand with pricing power. A financial service with network effects. These businesses do not need to reinvest enormous sums to grow. They can return cash to shareholders, fund acquisitions cheaply, or invest selectively in new opportunities. Companies that destroy capital typically have weak competitive positions, high operating leverage, or commodity-like profitability margins.

Who buys TMFE, and what problem does it solve?

Investors buy TMFE because they believe capital-efficient businesses are higher-quality, lower-risk, and better long-term performers than the broad market. The logic is sound: if a company earns high returns on its capital, management is creating value. If it can sustain those returns, it can compound that value over time. This appeals to fundamental investors who care about the quality of earnings and the durability of competitive advantage.

TMFE is also attractive to value-conscious investors. A capital-efficient business that trades at a reasonable valuation is often a better bargain than a capital-intensive business—which requires constant heavy reinvestment just to stay competitive—trading at a low price. You are buying the right kind of cheapness: an efficient, profitable business trading below the premium valuations it might deserve, rather than a deeply discounted wreck.

The fund also serves as a quality filter. In a broad large-cap index, you own some capital guzzlers—companies in capital-intensive sectors like utilities or industrials that must reinvest heavily to maintain their position. In TMFE, those are screened out unless they happen to be exceptional capital generators. The result is a portfolio skewed toward tech, financials, healthcare, and consumer—sectors with naturally higher returns on capital—and away from energy, transport, and utilities.

How it differs from a passive index

TMFE is not a mechanical index like the S&P 500, which just holds five hundred companies weighted by market cap. It is a curated selection designed to favor a specific financial characteristic. That means TMFE will always look different from the broad market. It will usually have lower debt levels, higher profitability margins, and companies trading on price-to-earnings ratios that reflect their quality. It will outperform in years when capital-efficient businesses are in favour, and it may lag when the market favours cheaper, lower-quality names, or when market leadership swings to capital-intensive industries.

The expense ratio is reasonable—typically in the low-to-mid twenties basis points—reflecting the research required to maintain the screen and the modest amount of annual turnover as companies move in and out of the index.

What can go wrong

One risk is concentration in style. If the market rotates away from quality and toward cheap, value-driven cyclicals, TMFE can lag persistently. This happened, for instance, when 2022 brought soaring interest rates and growth stocks—many of which have high capital efficiency—fell sharply while beaten-down value stocks rallied. TMFE owned many growth names; it underperformed.

Another is the risk that yesterday’s capital-efficient business becomes tomorrow’s capital trap. A company can lose its competitive advantage. Technology shifts, competition intensifies, or customer preferences change. A business that once earned spectacular returns on its capital may be reinvesting heavily just to keep market share. The screen is backward-looking; it identifies efficiency that has already been demonstrated, not efficiency that will be demonstrated.

Concentration within the one hundred holdings is also real. The fund is not as diversified as a passive three-thousand-stock index. A handful of names in favourable sectors might comprise a large portion of the index, so a change in sentiment around those few companies can move the fund meaningfully.

How to research TMFE

Start with the fund’s fact sheet and holdings list. Look at the top twenty or thirty names and ask: do these look like capital-efficient businesses? Do they have durable competitive advantages? Check the sector breakdown. If you see it is overweight technology and financials while light on energy and industrials, that is a sign the capital-efficiency screen is doing its job.

Review the selection criteria in detail. How exactly does Motley Fool define return on invested capital? What thresholds must a company meet? Is there judgment applied, or is it purely mechanical? Compare TMFE’s returns to TMFC (Motley Fool’s general-purpose index) and to a broad large-cap benchmark. Has the more selective, quality-focused approach paid off, or have the returns been similar? Over different market cycles, capital efficiency becomes more or less valuable. Understanding that pattern helps you decide whether the fund fits your portfolio and time horizon.
