What We Cover

The building blocks, explained one at a time

Investing is a small number of ideas wearing a large number of names. We cover the ones that change what you end up holding.

01 / BUSINESSES

How a company earns its money

What the company sells, who pays for it, what delivery costs, how much it owes and when that debt comes due — read out of the filings in ordinary language, with the numbers left in.

02 / INSTRUMENTS

Funds, bonds, and the wrappers around them

What an index fund actually holds, how a bond pays and what happens when rates move, what a dividend is and is not, and how fees inside a product show up in a balance years later.

03 / COSTS & TIME

The inputs you can know in advance

Expense ratios, spreads, trading costs, taxes, contribution size, holding period, and diversification — the knowable parts of the problem, worked through with plain arithmetic.

How an idea earns a write-up

  1. Read the primary document. The filing, the prospectus, the holdings list, or the rate sheet itself — not a summary written by someone selling the thing.
  2. Describe it in plain words. What it is and how the money moves, written so that someone meeting the term for the first time can follow it.
  3. Show the arithmetic. Two or three figures, how each is calculated, and what an ordinary value looks like for comparison.
  4. State what could go wrong. The assumptions behind the idea, the costs of being wrong, and the conditions under which doing nothing is the better answer.

What each issue contains

What we do not cover

We do not publish trade alerts, price predictions, or anything framed as a limited window. We do not tell readers what to buy, because that requires knowing a person's income, debts, timeline, and tolerance for loss, and a mailing list cannot know those things.

We also leave alone products we cannot explain honestly in a few plain paragraphs — structures whose risks only appear in the footnotes, and schemes whose appeal rests on the reader not asking where the money comes from. If it cannot be written out clearly, it is not our beat.

Nothing here is a recommendation. Investing involves risk, including loss of capital; a clear explanation makes an idea easier to understand, not more certain, and markets can disagree with sound reasoning for a very long time. See our disclaimer.
