THREE VERDICTS ON FRAMEWORK FIT

Gemstone.
Geode.
Sediment.

Every company a strategy evaluates lands in one of three tiers — a verdict on fit to a published framework, never an action to take. The evidence behind each verdict is cited to the filing.

PRICING ANNOUNCED AT LAUNCH

GEMSTONE
Strong match — the filings support the framework's criteria.
GEODE
Partial match — some criteria hold; others can't be verified from the filings.
SEDIMENT
No match — criteria not met. Kept as a turned-over stone for further research.

FIVE LENSES · THIRTEEN STRATEGIES

Published frameworks, applied identically

Each strategy is a fixed screen plus a fixed evaluation prompt, in the tradition of published value- and growth-investing research. Every subscriber who runs a strategy gets output from the identical criteria.

01 · VALUE

Cheapness with a margin of safety

From statistical net-nets to durable-moat franchises priced below their worth.

Deep Value (Net-Net) Quality-Value Rank Moat Value: Pricing Power Moat Value: Scale Economics
02 · GROWTH

Growth priced with discipline

Classification before comparison, PEG discipline, and the leaders proving it in the numbers.

Growth at a Reasonable Price Growth Leaders Momentum Leaders · PREVIEW
03 · QUALITY

Durable returns on capital

ROIC persistence, moat evidence, and fifteen-point qualitative depth read from the filings.

Quality Compounder 15-Point Qualitative
04 · INCOME

Payout streaks that can continue

Dividend growth streaks with the coverage and balance sheet to keep compounding them.

05 · EVENT & SIGNAL

Events the filings disclose

Corporate events and insider behavior that published research treats as informative.

HOW IT WORKS

Two stages, from universe to verdict

1
STAGE 1 · SCREEN

Filter the universe

Each strategy's fixed quantitative filters run against the SEC EDGAR operating universe. Near-miss rationales are kept, so you can see why a company dropped out.

2
STAGE 2 · EVALUATE

Read the filings

Survivors go to the strategy's AI evaluator, which reads targeted EDGAR sections and returns a Gemstone / Geode / Sediment verdict — every claim cited to its filing section.

DRILL IN

Check the evidence

Every verdict opens to scored dimensions, trap signals with their sources, and what couldn't be verified — flagged as unknowns, not papered over.

ANATOMY OF A VERDICT

Every claim carries its source

A verdict is not a number — it's a structured read of the filings. Every one carries the same four parts:

01
Assessment
A plain-English read of what the filings show, tied to the methodology's scoring rubric.
02
Scored dimensions
Verification scores per dimension — the gates that decide where the verdict lands.
03
Trap signals, cited
Every red flag names its source — form, section, date — so you can read it yourself.
04
Unknowns, kept honest
What the filings don't disclose is flagged as insufficient data — never filled in from memory.

Operating expenses grew proportionally at 4.1%, with no material one-time items identified in the provided MD&A or financial notes. The data integrity, earnings recurrence, and accounting quality scores all meet or exceed the minimum threshold of 3, with no disqualifiers triggered.
