What the Number on the Screen Cannot Tell You

Most of us meet investing through a number. It sits on a screen, clean and exact, sometimes to several decimal places, and it moves while everything else on the page stands still. When it rises, a decision feels wise. When it falls, yesterday's decision feels foolish. I wrote Price Is Not a Promise because neither of those feelings tells you much about the thing whose price is moving.

A price is a record of an agreement. At some moment somebody bought and somebody sold, and the screen reports what they settled on. That is useful. It is also very little. It cannot tell you what you actually own, what might make its value change, what it costs you to hold, or whether you could turn it back into money on the day you need it. The gap between the number and those answers is the whole subject of the book.

A market under a cloth

The picture I kept returning to while writing was a market where every stall shows a price tag but most of the goods are hidden under a cloth. Some tags change as you watch. One stallholder points to a rising figure as though it were an explanation. Another says nothing there has ever disappointed anyone. A third hands you a thick document and suggests you read it later. You have brought money you worked to save, and you would quite like to know what the cloth covers.

The book lifts that cloth slowly, one layer at a time. It starts with the screen, because that is where most people start. Then it goes down to the claims beneath: a share, which is a small piece of an uncertain business; a bond, which is a borrower's promise and only as sound as the borrower; a fund, which is a container holding many such claims under its own rules. From there it climbs back up to the account statement, the place where what actually happened to your money is finally written down.

A price is a point of agreement in a market. It is not a certificate of quality, a forecast of growth or a promise of repayment.

Coins, workshops and baskets

I wanted the book to be readable by someone with no background in accounting, so every example in it is invented and deliberately ordinary. Amounts are counted in coins, because the currency does not matter. There is a small workshop that repairs lamps, with a door that sticks in damp weather, which raises money from new owners and later borrows for a new machine. There is a basket of fruit gathered from several stalls, which turns out to be a good way of thinking about what a fund holds and what it charges for the carrying.

These scenes do a quiet job. Once you have stood in the workshop during an unexpectedly busy month, it becomes much easier to see why more orders are not the same as more profit. Once you have watched a lender with an urgent bill of their own try to pass their bond to someone else, the word maturity stops sounding like a savings jar you can open on a known day. Once you have held the basket, two funds with similar names stop looking like the same thing.

Why there are no tips

There is a strong pull, in writing about money, to end every chapter with an instruction. Buy this kind of fund. Divide your savings in this proportion. Wait this many years. I have left all of that out on purpose. A book read by many people cannot know any one reader's life, and pretending otherwise would turn general education into private advice for nobody.

What I have tried to give instead is a set of questions that travel well. What, precisely, do I own or hold? Whose actions decide whether I receive what I expect? What does it cost, including the costs that are nearly invisible? When could I get my money back, and what might that require? Which of these questions has the person describing the product actually answered, and which are still open? The final chapter gathers them into a portable way of reading any investment claim, whatever the local rules happen to be.

It is a calm book, I hope. It does not try to frighten you away from investing or hurry you towards it. If you already invest, it may change what you look for on a statement. If you have not started, it may help you understand an investment before urgency takes over. If you are helping somebody else, it may give you a vocabulary that respects their choices.

The first question

You do not need to know anything to begin. You need only the willingness to keep asking what a word means. If a number on a screen has ever made you feel certain, or uneasy, without quite knowing why, open Price Is Not a Promise at the first chapter and we will lift the card together.
