The proof

Would any of this survive your accountant reading it?

That is the only test worth applying to a page like this one. So every exhibit below carries its own assumptions, its own arithmetic and the material it came out of, printed at the same size as the finding. Where two of our own decks disagree with each other, the flag stays on.

Not one of the exhibits below is a projection or a product. Start at the first one. It takes about four seconds and it catches nearly everybody who has ever read a statement.


Four answers. Only one of them can be right, because that is how multiple choice works.

A 25% average return over two years. How much do you have?

We open seminars with this one. It catches nearly everyone in the room, including the people who do this for a living, and it catches them in about four seconds. You start with $100,000. You hold it for two years. Over those two years the average annual return was 25%.

Work out your answer before you open anything. Then open the other three, because the arithmetic sitting under each of them is the part actually worth your time.

$100,000. Two years. The average return was 25%. Where does it land?

Workings opened

All four, then the answer opens. Two of them is where most people stop, and two of them is exactly where the point of this is hiding.

What it proves

An average annual return is close to meaningless as a way to judge what happened to your money, and it is still the figure printed largest on most statements. An arithmetic average cannot see a negative year compounding, which is the one thing you needed it to show you.

Assumptions, sourcing and flags

Arithmetic only, and deliberately extreme so the mechanism is visible. Real portfolios do not move like C or D, but the mechanism is identical at every scale. Not a recommendation, not a comment on any specific investment, and not a forecast.

Which of those is about your file?

Nothing above asks you to agree with it. It asks you to check it against your own numbers, and that is a fifteen minute job rather than a project. Bring the exhibit you think does not apply to you. Those turn out to be the useful calls.

Fifteen minutes. Nothing to send in advance, and no pitch on the first call.
