Where the method came from

Graham and Dodd in 1934, the revision of 1973, Buffett's turn to franchises, the efficient-market objection, and where the evidence leaves the tradition.

Value investing is not a discovery. It is a written tradition, about ninety years old, with named authors, dated books, arguments that were answered, and claims that have been tested since.

This course is that record. It starts with the market Graham and Dodd were writing about, which had almost no audited statements and no federal disclosure system. It ends with the state of the evidence today, honestly sorted into what has held up, what is contested, and what nobody has settled.

Two things run through it. The first is that every generation in this line moved the same question one step: Graham asked what the assets are worth, Buffett asked what the business earns on them, Greenwald asked what a competitor would have to spend to take the business away. The second is that the tradition has a serious opponent, and the opponent is stated here at full strength rather than dismissed.

Nothing in this course is a rule to apply. The rules live in the courses on either side of it. What you get here is the reason those rules exist, who wrote them down, and what happened when somebody measured them.

You need value-investing first, and reading-financial-statements helps, because the last lesson places a printed 1973 threshold in the market this product measures today.

What you will be able to do

Say what Graham and Dodd argued and under what conditions. Name the criteria Graham printed and the ones people attribute to him that he never wrote. State the efficient-market objection the way its authors state it. Describe what behavioural finance answered and what it left open. And say, without overclaiming in either direction, where the tradition actually stands.

How to read one, not a reading of yours

Where the method came from is 8 lessons on where a filed number comes from and what the filer was allowed to choose while producing it. It teaches you to read a statement. It reads none of yours: no company’s accounts are opened anywhere in it.

See our methodology for how the product reads a filing and what it refuses to compute.

Once a week, what changed in the filings of US-listed companies, why it can matter to a thesis, and what deserves a closer review. Grounded in filings, not market noise.
