The book in ten minutes

Every chapter's claim and its three lines, in order. Each heading leads to the chapter.

· Twenty-six tests, and what was left

A method built from good books was tested on history, most of it did not hold, and the rest of this book is what was left.

  1. Three months of building gave about 150 rules. Ten days of testing removed most of the mechanical ones.
  2. No edge was shown. An index fund is the base, and this method is the part that is studied.
  3. What remains is a valuation, a few rules about how figures are read, and the reading a person does by hand, measured the slow way.

Part One · The method

1 The problem

One person cannot read two thousand companies, and cannot tell from the inside whether a decision was careful or lucky.

  1. About two thousand companies, each with a report every quarter. Nobody reads them all.
  2. Buying on a story is the usual substitute, and a story is not a reason.
  3. Even careful work cannot check itself from the inside. The rest of the book is habits that can be checked from the outside.

2 What value investing is

A share is a piece of a business with a value, the market quotes a different number called the price, and you buy only when the price is well below your estimate of the value.

  1. Value is what a business's spare cash is worth. Price is what the market quotes today.
  2. Your estimate of value will be wrong, so you leave room: the margin of safety.
  3. Patience is a step in the procedure. The number written down in advance does the waiting.

3 This project's flavour

The tool measures and remembers; a person decides, and every decision is written down with its date.

  1. Figures come only from the company's own filings, and the owner's view of growth is written before the market's number is seen.
  2. A failed test stays failed, and a rule changes only on a test registered in advance.
  3. Every refusal is tracked. The tool measures; the person decides.

4 The screener: two thousand to a handful

A screen does not find good companies; it removes the ones that fail a few coarse tests, so that reading time goes to what is left.

  1. The list of two thousand is fixed and dated, never fetched live.
  2. The screen asks only what a machine can ask of public figures: is the data fresh, is there five years of history, did the business make cash?
  3. What comes out is a reading list in a fixed random order, with no value and no opinion.

5 Why a name is refused, and why that is the normal outcome

Most companies that are read are refused, a company that fails on a fact about its business stays refused at any price, and 'I cannot judge this' is a real answer.

  1. The first question is why the price fell. If you cannot say, treat the business as broken.
  2. Four warning signs end a reading on their own.
  3. A name that failed on something other than price comes back only on a named new fact, never on a lower price.

6 What gets read

A figure counts only if you can point to the filing, the period and the page it came from; everything else is hearsay.

  1. Every figure carries where it came from, which period it covers, and whether anyone has checked it.
  2. Nothing is scaled, annualised or borrowed from another period. A figure of the wrong length is missing.
  3. A valuation refuses to run on a figure nobody has read back.

7 The reverse DCF

Do not ask what a business is worth; ask what growth today's price assumes, and whether you believe it.

  1. Run the valuation backwards: from the price, solve for the growth it needs.
  2. The answer is an assumption you can argue with, not a number you have to trust.
  3. The arithmetic is fixed (ten years, then 2.5 percent, a 9.5 percent required return), so the only thing left to disagree about is growth.

8 Pre-registration: write the belief before you see the number

Write down the growth you believe before you calculate the growth the price assumes, or your belief will quietly move to meet it.

  1. Three growth rates, low, base and high, are written with their reasons and timestamped.
  2. Only then is the price's own assumption calculated.
  3. If the market's number was seen first, the view is void for that company in that round.

9 The three outcomes

Every test ends in pass, fail or data missing, and the third is never quietly turned into the second.

  1. PASS and FAIL mean the test ran. DATA MISSING means it could not.
  2. A missing figure is a fact about the data, not about the company.
  3. DATA MISSING is information: it says what to go and find, and how much of the method is actually running.

10 The funnel: six statuses

Every company the method has touched is in exactly one of six states, and only a person moves it from one to another.

  1. Six statuses: in the pipeline, read but not watched, watched for price, watched behind a gate, held, dropped.
  2. The tool reports where a name stands and points when something crosses a line. It never moves a name.
  3. The master list puts all of them on one page, rebuilt every night.

11 The decision

A decision is never 'buy': it is a price, the conditions and the exit, written down before any money moves.

  1. X is the most you will pay: the value times a cushion set by how well you understand the business. It is shown as information.
  2. Y is the conditions that must still hold. Z is the exit, written while you have no stake in the answer.
  3. At most six percent of the portfolio goes into one company.

12 The shadow book

A method that only measures what it bought cannot learn, so every refusal and every sale is priced against the index afterwards.

  1. Each refusal is one row: the company, the date, the verdict, the price that day and one line of reason.
  2. It is set against an index over the same period, in the same currency and the same kind of return.
  3. It is not a signal and nothing reads it. It is looked at once a year, so that it cannot bend the rules.

The tests

13 What the tests removed

A rule that sounds right is not evidence: every mechanical rule was tested on history under a bar set in advance, and most were removed.

  1. Each test was written down before it ran, and a rule held only if it helped in both markets and in both halves of each period.
  2. The stop, the band, the ranking, three warning signs, the debt limits and the cushion as a buy line were removed.
  3. No edge was found. The history is closed, and the next test runs on new data in April 2027.

Part Two · The machine

14 How the machine reads

The machine may measure and remember but not decide, and it refuses to print a value whose origin has a gap.

  1. The tool measures; the owner decides. No part that runs on a schedule may write a decision.
  2. A value is printed only from a complete run record: every input and every choice, or nothing.
  3. The rules are a dated document first, and the code implements them.

15 How it watches

The machine watches every night and speaks only when something changed, so its silence has to be made trustworthy.

  1. Every night prices are held against decisions already made, and each new report is read and the company valued again.
  2. The phone hears only a change.
  3. Two observers make silence mean something: one on the machine says what broke, one outside notices when nothing arrives.

16 The bug museum

Every wrong number this project caught was caught by reading a whole table or by two things failing to agree, never by searching for it.

  1. Units, tickers, empty fields and sentences all go wrong quietly.
  2. A filter finds what you already suspect. Reading everything finds the rest.
  3. Each fault left a rule behind: no arithmetic across units, empty is not zero, and a fix made after a result is counted as one more look.

17 What it does not do

The tool cannot tell you a business is good, cannot make you patient and cannot stop you overriding it, and the last of those is on purpose.

  1. The limits on security and monitoring are written down, not hidden.
  2. The method cannot judge a business for you, and cannot supply patience.
  3. The scheduled machine decides nothing, on purpose: a tool that decided would be trusted, and a trusted tool stops being checked.

The close

18 The slow way, made survivable

There is no easy way: the method is slow on purpose, and the machine exists to keep the slowness honest.

  1. The method was written before the code, and the code cannot overrule it.
  2. Every refusal is measured, and every rule was tested where it could be.
  3. No edge was found. What is left is reading, writing things down first, and checking afterwards.

The slow way, made survivable. Built 2026-11-09 from the repository as it stood that day. NAME A and NAME B are fictional. One real company, CENTA, is followed through the book, with figures from its own filings and the owner's own trades. Not financial advice: one private investor's method, shared as it is.
