How to make a list of ideas judge itself: attach four comparable numbers to every name, compress each thesis to one falsifiable claim, and let the underwriting case stand without growth.

How to read this page: a crowd-sourced idea list, but the formatting choices are the method — the closing scorecard does the grading, and three of the entries model different ways to state a thesis in one paragraph. Written post, so no timestamps.

1. Close every idea list with the same four numbers, and let the table do the judging

The repeatable method
  1. Pick four columns that between them cover profitability, capital efficiency, price and growth — here net profit margin, ROIC, forward PE and long-term expected EPS growth.
  2. Apply them identically to every name, including the ones you are enthusiastic about and the ones you would never own.
  3. Colour-code against your own thresholds rather than against the list's internal range, so a list of bad businesses cannot grade on a curve.
  4. Publish the table without commentary. If the numbers contradict the prose, that is the useful part.
Here: the closing sheet puts EVO.ST (50.6% margin, 27.0% ROIC, 10.5x) and TSLA (5.3% margin, 5.3% ROIC, 215.3x) in the same nine rows, and prints the crowd's #1 pick, MELI, at 43.6x on a 7.9% margin and 8.4% ROIC. Against the house thresholds (margin >10%, ROIC >15%) only five of ten clear both. Not a sentence of the prose says this.

2. Compress a thesis to one claim you could be publicly wrong about

The repeatable method
  1. Ask what single measurable fact the case depends on, and write it as a sentence with a number in it.
  2. Source that number to a primary document — an investor presentation, a filing — with the date, so it can be rechecked.
  3. Show the trend across at least two points, so the claim is an extrapolation rather than an assertion.
  4. Commit to abandoning the position if the number stops moving, and say so in advance.
Here: "The investment thesis depends on one simple fact: Kinsale could double its market share in the next few years. In 2024, their market share was 1.4%… When we look at 2021, their market share was just 0.9%" — each figure cited to a named investor presentation (October 2025 and August 2023). Everything else about KNSL is treated as supporting detail.

3. Build the case that works even if growth is zero

The repeatable method
  1. State the deterioration plainly first, without hedging, so the case is not resting on denying it.
  2. Compute shareholder yield — dividends plus net buybacks — as a percentage of market value at today's price.
  3. Ask whether that yield alone clears your required return. If it does, growth becomes optionality rather than a requirement.
  4. Name the one assumption still doing work, usually that current earnings hold — and monitor that, not the growth rate.
Here: EVO.ST — "Revenue is declining for the first time ever… However, the company could deliver excellent returns to shareholders. Even without growth. The current shareholder yield is over 10% (dividends + share buybacks)." The load-bearing clause is the last one: "especially since we expect Evolution AB to keep growing its intrinsic value." At 10.5x earnings and a 50.6% net margin the buyback retires a large slice of the company each year — provided the earnings hold.

4. Read the pay package as a business input, not a governance footnote

The repeatable method
  1. For any founder- or owner-led business, find what the chief executive is paid and what triggers it.
  2. Ask what behaviour the package rewards — a share price on a date, a revenue milestone, nothing at all.
  3. Match that against the behaviour the business model needs. A permanent-capital acquirer needs patience; a target-linked award buys urgency.
  4. Weight publicity-seeking the same way: a chief executive who has promised a number in public has a reason not to walk away from a bad deal.
Here: the two ends of the same list. CSU.TO — "Musk craves the spotlight, Leonard avoids it completely; Elon makes bold promises, while Leonard is careful and conservative; Leonard didn't have a pay package in the last three years." TSLA — a $8.5 trillion ten-year ambition against a $1.4 trillion market cap, and "a bonus worth $1 trillion in Tesla shares" if the targets are hit. No valuation argument is made against Tesla anywhere in the issue; the contrast is the argument.

5. Haircut management's own targets before building a return on them

The repeatable method
  1. Convert multi-year targets into implied annual growth rates so their aggressiveness is visible.
  2. Apply your standard discount to forecasts — the house habit elsewhere in this archive is 30-40% off analyst estimates.
  3. Rerun the valuation at the haircut number and see whether the case survives.
  4. Check the metric the targets are set in, and whether it is the one that reaches shareholders.
Here: KPG.AX's FY31 slide — "Revenue: $500 million; EBITDA: $175 million; NPATA: $40 million" → "Revenue: +24.4%; EBITDA: +31.4%; NPATA: +28.2%" — is taken at face value with no discount applied, which is a departure from the same author's stated practice. The reported net margin in the issue's own table is 2.5%, which is why NPATA rather than earnings is the working metric for this business.

6. Discount a "wisdom of crowds" result by how correlated the crowd is

The repeatable method
  1. Ask where the respondents got their information. The cow-weighing result requires independent guesses.
  2. Check the overlap between the crowd's answers and the surveyor's own published positions.
  3. Treat high overlap as evidence of reflection, not of consensus — the list is measuring readership, not the market.
  4. Use it as a sentiment gauge on your own holdings rather than as idea generation.
Here: the framing is explicit — "when you take the average of all guesses, it is almost exactly correct" — and six of the ten picks are Compounding Quality holdings (NVO, CSU.TO, EVO.ST, KPG.AX, KNSL, and ZTS from 29 January). The prior year's version is the control: the most-picked name of 2025, by three times the votes, was EVO.ST, and it fell 28.5% (8 January).
