Pieter Slegers — The ultimate stock screener?

"How I eliminate 99% of stocks": the house quality criteria typed into a Fiscal.ai screener as eight hard filters (growth, margins, capital intensity, ROIC, ROCE), China and banks excluded — fewer than 100 survivors from 50,000+, three sorted leader lists, and five favourites: ASML, Fastenal, MSCI, Hermès, Mastercard.

One-line take: the archive's first time the quality framework is run as a mechanical screen rather than a worksheet, and the post is the recipe more than the picks. The eight filters are 5-yr revenue CAGR >5% · 5-yr diluted EPS CAGR >7% · 5-yr gross margin >40% · 5-yr net margin >10% · 3-yr FCF margin >10% · CapEx/revenue <5% · 3-yr ROIC >15% · 3-yr ROCE >20%, with China and banks excluded — "Out of 50,000+ companies, this screen found fewer than 100 worth a closer look." The five favourites get a one-paragraph business model and four metrics each, but no valuation, no price and no rating, and none of the five is in the portfolio (Games Workshop, a high-ROIC passer, is the only held name mentioned). Four things to hold against it. (1) The capital-intensity filter looks inoperative: the settings screenshot shows it typed as 0.05 in a percentage box, and the "CapEx to Revenue" column reads 0 for every one of the 36 visible survivors, including Nvidia, Lam Research and Games Workshop. (2) The leader lists are hand-picked from the sorts: the revenue sort's #3 is Kaspi.kz (45.7%) not Arista; the EPS sort is led by IHG at 235%, with Nvidia (95.1%) and Booking (86.4%) ahead of Exelixis. (3) The country rule is thinner than stated: China is excluded, yet PDD passes and is named, and Kaspi (Kazakhstan) and DLocal (Uruguay) pass — all at odds with the 1 September developed-countries-only policy. (4) Data artefacts pass as quality: Mastercard and Rightmove show a 100.0% gross margin (no cost-of-sales line), VeriSign a 1,687.8% ROCE, and including OTC Pink/OTCBB lets microcaps through (Love Group Global at a $2.77m market cap).

1. Stocks & names mentioned

Stance reflects how each name is framed in this post, not a price rating. The five "favorite ones" are Positive (argued as quality businesses; no valuation or purchase). The nine names cited in the prose as top of a sort (revenue growth, EPS growth, ROIC) are Neutral — screen output, not picks. The further names that appear only inside the result-table screenshots (Kaspi.kz, IHG, Booking, Pro Medicus, VeriSign, FICO, Apple and ~25 others) are transcribed in transcript.txt but get no rows here. Rightmove (London) uses the .L row id. Research legend: QT Qualtrim · SA Seeking Alpha · STK Stock Analysis. Written post with no timestamps — the At link opens the article.

Checks against the post's own images. (1) CapEx filter: entered as a maximum of 0.05 in a field the other seven criteria fill in percent, and the CapEx-to-Revenue column shows 0 for every visible survivor — either the field is unpopulated or the filter is not binding, so "low capital intensity" is not actually tested. (2) Cherry-picked leaders: revenue sort order is NVDA, DLO, KSPI 45.7%, PDD, LNTH, HRMY, HALO, ANET; EPS sort is IHG 235.0%, APP, NVDA 95.1%, PDD 95.1%, BKNG 86.4%, EXEL. (3) Screen universe: exchanges include OTC Pink and OTCBB, which admits Love Group Global ($2.77m), Rave Restaurant Group ($43m) and Record plc ($110m) beside Apple; "Deckers Outdoors" is the post's spelling. (4) Metric windows: the favourites' quoted CAGRs differ slightly from their own Fiscal.ai charts (ASML revenue 16.3% vs 16.5%; Fastenal EPS 9.3% vs 10.0%) because the charts run 2017-LTM rather than five years. (5) Chart sources: the "Source: Morgan Stanley" exhibit is BCG/Morgan Stanley data on S&P 500 top-quartile performers for 1990-2009; the capital-light exhibit ends in 2021.

3. In plain English

MA — Mastercard Positive

Mastercard doesn't lend money or issue cards — banks do that. It runs the network that carries the payment from your card to the shop, and takes a tiny cut of every transaction. Because the pipes are already built, an extra payment costs it almost nothing, so most new revenue drops straight to profit. Shops accept it because shoppers carry it, and shoppers carry it because shops accept it, which leaves room for only one real rival, Visa.

The newsletter ranks it first of five quality names the screen found: revenue up about 16% a year for five years, profit per share up about 20%, and roughly 42 cents of operating profit on every dollar invested in the business. It gives no price or valuation this time; two weeks earlier it was the newsletter's top "Best Buy".

RMS.PA — Hermès Positive

Hermès makes handbags, silk scarves and clothes at the very top of the luxury market. Its trick is to make fewer bags than people want, by hand, so it never discounts and never has leftover stock. That scarcity is why buyers wait, and why about 71 cents of every sales dollar is left after the cost of making the product — a figure that has barely moved in a decade.

The screen passes it on every test, and the post calls its profits "high and stable in almost any economy." There is no valuation here; the case for buying now was made in late August, when the shares had fallen about 30%.

MSCI — MSCI Inc. Positive

MSCI builds stock-market indexes — lists like "MSCI World" or "MSCI Emerging Markets" that funds copy or measure themselves against — and sells the data behind them. Index funds pay it a fee based on how much money follows its lists, and that money has grown from about $0.7 trillion in 2017 to about $2.8 trillion.

The argument is that switching is painful: a fund's benchmark is written into its legal documents, so changing it is costly and slow, and customers tend to stay for good. That gives MSCI room to raise prices. The post lists strong growth and margins but gives no view on the share price.

FAST — Fastenal Positive

Fastenal sells the unglamorous stuff factories and building sites burn through — screws, bolts, gloves, tools. Its twist is putting its own vending machines inside customers' buildings, so a worker grabs what they need on the spot and Fastenal restocks automatically. Once the machines are installed, a customer has little reason to call anyone else.

The post calls it "a slow, boring, highly profitable compounder": sales have roughly doubled since 2017 and profit per share has more than doubled, with about 30 cents of profit a year on each dollar invested. It is growing more slowly than the other four favourites, and the post gives no valuation.

ASML — ASML Holding Positive

ASML, a Dutch company, makes the enormous machines that print circuits onto chips. For the most advanced chips — the ones in phones and AI servers — it is the only supplier in the world, so every leading chipmaker has to buy from it.

The post's case is simple: more demand for advanced chips means more ASML machines sold, and sales have roughly quadrupled since 2017. What it does not discuss is that chipmakers buy these machines in waves, so orders can stall (2024 was nearly flat), and that export rules on selling to China are a political risk. No price or valuation is given.
