The Bedrock screener.

A boring portfolio is a feature, not a bug. The Bedrock screener exists because most weeks I don't want surprises — I want a list of large, well-run businesses that are quietly returning capital to their shareholders. The Bedrock is the screener that produces that list.

This post is the what and the why of the Bedrock. It is not the recipe. The exact gates, weights, and thresholds stay behind the curtain. The shape is the post; the specifics aren't.

If you haven't read the Blue Portfolio yet, start there. The Bedrock is one of three screeners that run Layer 2 and Layer 3 of that pipeline. The Prospector is the cap-unbounded sibling; this one is the large-cap-only anchor.

The claim

The Bedrock's job, in one sentence: surface a pool of large-cap names — every one of them comfortably above the $50-billion line — that pass the Council's full quality, valuation, and leverage discipline AND are demonstrably returning capital to their shareholders. Not the fastest compounders. Not the most undervalued. The most boring of the genuinely high-quality businesses.

The portfolio's stability anchor. The names I'd be comfortable owning through a recession. The opposite of a story stock.

Why a large-cap floor

Most retail screeners are cap-unbounded. The Bedrock is the only one of mine with an explicit cap floor. Three reasons.

Survivability. A company comfortably over $50 billion in market cap has the balance sheet, the customer base, and the scale to survive a deep recession without an existential crisis. A $5-billion company in the same industry might not. The Bedrock is the part of the strategy that's least willing to take that risk.

Capital-return discipline. Large-cap companies are the ones with the cash flows and the boards capable of running consistent buyback programmes, paying real dividends, and paying down debt. The Council's Thorndike-school prescription — the eight CEOs in William Thorndike's The Outsiders who outperformed by being unfashionable about capital allocation — is almost entirely a large-cap phenomenon. You can't run a meaningful buyback at $1 billion.

Partition with Quantum. The third screener in this pipeline, Quantum, has the opposite cap ceiling — below $50 billion only. Together, Bedrock and Quantum span the full cap spectrum with explicit, complementary mandates. The Prospector overlaps both at the high-conviction tail. Three screeners, no gaps, deliberate overlap where it matters.

The framework — the same four questions, asked differently

The Bedrock asks the same four questions the Prospector does — is the business good, is the price sensible, does it survive a bad year, is it accelerating? — but it asks them through a different lens.

Quality at the Council floor, not the strict target. The Prospector tightens the quality bar above the Council's distress-avoidance floor; the Bedrock sits at the floor. The job isn't to find the highest-quality businesses — it's to find financially intact large-caps that are returning capital. Tightening above the floor would shrink the pool below what a stability anchor needs.

Valuation discipline identical to the Prospector. Same insistence on a sensible price relative to discounted-cash-flow fair value; same ceilings on multiples like price-to-earnings, with the ceiling pulled lower for businesses carrying more debt. The Council's valuation rules don't bend for the large-cap version of the screen.

Leverage discipline identical too. Distress composites, leverage caps, interest-coverage floors. The reasoning hasn't changed.

A stricter sentiment filter. The Bedrock tightens the consensus-skepticism gate — near-consensus only. The stability-anchor job doesn't want to be the early reader on names where a meaningful slice of the float is actively betting against them. Floor-vs-target rule again: the Council sets the absolute floor; each screener tightens where the job justifies.

Momentum as a soft floor. The full six-factor Navellier Momentum Score as the hard cutoff — fail it and the name is out. A value trap with no momentum confirmation doesn't make it through.

And then, on top of all of that, the ranking step is where the Bedrock most clearly diverges from its siblings: it ranks names by how aggressively they're returning capital to their owners. The dominant ranking signal is shareholder yield — total capital returned (dividends, buybacks, debt paydown) as a fraction of market cap. The specific weight stays under the hood. The dominance is the point.

A worked example — what a Bedrock hit looks like

I won't name a ticker — same reason as the Prospector post. The shape of a typical hit instead:

• A business comfortably above the cap floor — too large to be wiped out by an ordinary recession.
• A respectable return on equity and on invested capital, sustained for years. Not the highest in the universe, but reliably above the Council's baseline.
• Margins in the high teens or better, expanding or stable.
• A price at or below a sensible DCF estimate of fair value.
• A clean balance sheet — leverage well within survivable territory, distress composites in the safe zone.
• Momentum confirmation across most of the six NMS factors.
• A capital-return profile in the meaningful single-digit-percentage range — the business is returning a real fraction of its market cap to shareholders each year through dividends, buybacks, and debt paydown.

That last item — the capital-return profile — is the one the Bedrock cares about most. A business returning a real, sustained percentage of its market cap to shareholders each year, at a sensible valuation, with a clean balance sheet, on a large enough base to survive a recession, is the kind of position you can hold through a downturn and probably want to hold through one — because the buyback gets cheaper when the price falls.

The edge cases — where the Bedrock falls short

It misses early-stage compounders. A great business at $20 billion in market cap doesn't make it through the cap floor. The Bedrock would have rejected Amazon in 2008 and Nvidia in 2015. That's a real cost. The Prospector and Quantum exist to cover this gap.

It overweights mature dividend payers. The capital-return ranking will tend to push the screener toward mature, slower-growth businesses with high-yield programmes. That's mostly a feature — the stability anchor role is supposed to look that way — but it does mean Bedrock hits are rarely the most exciting names in any given week. A reader hoping for the next 10-bagger should look elsewhere in the pipeline.

It can over-filter in expensive-large-cap regimes. When the broad market is in Marks-pendulum-extreme territory and every large-cap is trading at a stretched multiple, the valuation gates reject most of the universe at once. The output drops sharply. That's the screener telling me something — be patient, the regime is wrong — not the screener being broken.

Capital-return discipline doesn't equal capital-return honesty. Some companies inflate buybacks to offset stock-based compensation, leaving net share count flat while the optics look great. The screener's gates mostly catch this, but it's worth saying out loud. Layer 5 verification looks for the gap.

Where this fits — the rest of the pipeline

Bedrock's job ends at the candidate list. The same Layer 4 / Layer 5 work follows.

A Bedrock hit that also passes the Prospector is a particularly strong signal — a high-conviction, large-cap, capital-returning business is what almost every author on the Council would describe as the bullseye of the strategy. Two screeners independently surfacing the same name through different selection logic is the strongest pre-Layer-4 signal the pipeline produces.

A Bedrock hit without a Prospector hit is usually a large-cap with great capital-return discipline but a quality score that's good enough rather than strict-quality. Those are real positions too — slower compounders that still deserve a spot in the book — they just deserve a closer Layer 5 look at the moat tag.

What this means for you

If you're a reader who'd rather own boring than exciting — which, after a few full cycles in this market, includes most experienced investors — the Bedrock's posture is a reasonable template. Quality at the Council floor, sensible valuation, financial intactness, ranked on capital return is a roughly Outsider-school stance. You won't beat a high-flying growth manager in a bull year. You probably won't lose much in a bear one.

For the reader who's still building wealth and doesn't want a job: keep contributing to the ETF Portfolio instead. Almost every Bedrock-style discipline is already inside a broad-market index fund, except for the active selection — and the active selection has to earn its keep over multi-year stretches before it's worth the time. Bogle's argument is still binding.

How the pieces fit

Three screeners, one pipeline.

• The Prospector is the broad-cap conviction hunter.
• The Bedrock is the large-cap stability anchor.
• Quantum is the strict-momentum smaller-cap hunter. Future post.

The Bedrock is the screener I'd point a reader to if I had to pick one to explain the system. Its design is the Council's most cited prescriptions made operational. Quality at the floor, valuation honest to a model, leverage in the conservative zone, ranked on capital-return discipline. Run the same shape every Saturday morning. Sit through the zero-hit weeks. Let the boring portfolio do the boring work.
