Rule 4 · The evidence

The index weights you by price. We tilt toward substance.

This is the long version — the research and reasoning behind how we build portfolios. For the short version, see Strategy.

Index funds are a real achievement — low-cost, broadly diversified, and hard to beat by picking stocks. But a capitalization-weighted index makes one quiet decision on your behalf. This is the economic and academic case for a more deliberate approach — told without a single performance chart.

The short version
Three business characteristics — value, profitability, and a measured lean toward smaller companies — have been rewarded across many decades and dozens of countries, with a clear economic reason to expect that to continue. We tilt toward them primarily through free cash flow, because cash is far harder to manipulate than reported earnings. None of it requires taking our word for anything: the research is public, and the reasoning is below.

The starting point

A starting line, not a finish line.

A cap-weighted index owns companies in proportion to their market price. When a company's shares double, it becomes twice as large in your portfolio — whether or not the underlying business became any better.

Over time this does something subtle. You automatically come to own the most of whatever has already grown largest and most expensive, and the least of what is cheap or overlooked. It is a sensible default, and for many investors a fine place to begin. But it is not neutral: it is a standing bet that today's biggest, priciest companies will keep leading — and history has not always rewarded that bet.

You come to own the most of whatever has already become the most expensive.
The evidence

Three characteristics the research keeps pointing to.

For more than half a century, academics and practitioners have asked a simple question: are there durable, well-understood traits that tend to reward patient investors? Three keep surfacing. Just as importantly, they are largely independent of one another — so holding all three diversifies the very reasons a portfolio is expected to be rewarded, rather than leaning on a single idea.

Value

Paying a fair price for what you own.

Buying a business for less relative to what it truly generates. We measure that cheapness first against a company's free cash flow — the cash left after it has paid its bills and funded its operations — rather than accounting earnings alone, because cash is far harder to massage than reported profit. The idea is old and intuitive, running from Benjamin Graham, who taught Warren Buffett, to the research that placed it on a rigorous footing decades later. Why should patience here be rewarded? Partly because cheaper companies are often unloved or uncertain, and investors expect compensation for holding what others avoid; partly because people tend to overpay for exciting stories and underpay for dull, dependable businesses.

Profitability

Favoring genuinely strong businesses.

Companies that generate more profit — and, we would add, more cash — from their operations. Screening on cash-based profitability rather than earnings alone keeps the focus on businesses whose strength is real and spendable. This is the most recently formalized of the three — the economist Robert Novy-Marx documented it clearly in 2013 — and it does something valuable alongside value: it helps separate a real bargain from a company that is cheap for a good reason. Owning businesses that are both reasonably priced and genuinely productive is a sturdier idea than either trait alone.

Size

A measured lean toward smaller companies.

Smaller companies have long been studied as a source of return, first documented by Rolf Banz in 1981. We treat this one with the most humility: on its own it is the least reliable of the three. Its value tends to show up in combination — smaller companies that are also cheaper and more profitable — rather than simply owning small for its own sake.

The common thread

It all comes back to free cash flow.

The three characteristics can sound like separate ideas. In practice they meet at a single point — the free cash flow a business produces: the money genuinely left over after it has paid its bills and reinvested in itself.

That one figure lets us express two of our principles at once. A company can be cheap on cash — priced modestly against the cash it throws off — which is our sharpest measure of value. And it can be strong in cash — generating a great deal of it relative to its size — which is our clearest sign of quality. Cheap and strong, measured the same honest way.

Earnings can be shaped by accounting choices. Cash either arrived, or it didn't.

That is the quiet reason we lean on cash flow throughout. Reported earnings can be flattered by depreciation schedules, one-time charges, and judgment calls; free cash flow is far harder to manufacture. Anchoring both the value screen and the quality screen to cash keeps the portfolio focused on tangible business substance rather than accounting appearance.

It is not a perfect measure on its own — a company investing heavily to grow can show modest cash flow today and still be excellent — which is exactly why we pair it with value and profitability rather than relying on any single number. Used together, they point consistently toward the same kind of business: productive, durable, and reasonably priced.

Why it holds

Not a fluke of one market or one era.

A pattern found once, in one country, over one decade, is easy to dismiss as luck. What makes these characteristics compelling is their breadth. They have been observed across many decades, in dozens of countries, and even in other kinds of markets. They were described in academic journals long ago and have been examined relentlessly ever since.

A pattern found once is luck. A pattern found across dozens of countries and many decades is something else.

There are two leading explanations for why they endure — and, reassuringly, both point to persistence.

Explanation one · Risk
Some of these businesses are genuinely less comfortable to own — less certain, less celebrated, harder to hold through a downturn. Investors are compensated for that patience. Risk that is real does not disappear because it becomes well known.
Explanation two · Human behavior
The impulse to chase the glamorous and shun the unglamorous is a deeply human habit, not a temporary market inefficiency. It has been documented for as long as there have been markets, and it is unlikely to be trained away.

Whichever weighs more heavily, neither is likely to vanish. It is also worth noting the standing of this work: Eugene Fama, whose research put much of it on rigorous footing, was awarded the Nobel Prize in Economic Sciences in 2013. These are not fringe ideas; they are part of the foundation of modern finance.

The thread

One idea underneath all three.

For all their academic names, the three characteristics share a single, intuitive thread: each leans away from the crowded, expensive, glamorous end of the market and toward businesses that are cheaper, stronger, and sometimes smaller.

It is a disciplined, rules-based way of doing what careful investors have always tried to do — own good businesses at fair prices — applied consistently across thousands of companies rather than a handful of hunches. The index sorts by price. This approach sorts by substance.

In plain terms

What this approach is — and what it isn't.

It is
  • Grounded in economics and decades of evidence, not forecasts or hunches.
  • A way to diversify the reasons a portfolio is expected to be rewarded.
  • Built to be held patiently, across many years and many environments.
It isn't
  • A promise of better results in any given year — these tilts can trail the broad index for uncomfortably long stretches.
  • A market-timing tool, or a way to sidestep downturns. In a severe, system-wide crisis, equities of all kinds can fall together.
  • A guarantee. Like all investing, it carries risk, including possible loss of principal.

The single most important ingredient is patience. An approach built to look different from the index will, at times, feel different — and the willingness to stay the course is what turns sound evidence into real outcomes.

Next step
The reasoning is sound. The evidence is broad.

We build portfolios this way because the discipline is repeatable. If the logic resonates, the next conversation is about how it applies to your situation — twenty minutes, no preparation required.
