Questions

Every other section on this site is organised the way the subject is organised — by instrument, by mechanism, by document. This one is organised the way a question arrives: in the middle of the night, in plain words, usually after something has already happened. Each page answers one of them properly and then points at the pages that go deeper. All of it is information and education only — see the disclaimer.

The badges say how much a page assumes: Start here nothing beyond plain English · Some background helps one concept from elsewhere on the site · Assumes the mechanics written for someone already inside the market.

Starting from nothing

• What is a share, really?Start herea vote, a claim on what is left over, and no promise of anything. Where the return comes from and why you are last in the queue.
• What is an option, in plain words?Start herecalls, puts, the premium, and the three ordinary reasons an option loses money on a day the market went your way.
• What actually happens when I press buy?Start hererouting, matching, the spread you paid without being charged it, and why you own the share two days later.
• What do the fees actually cost me?Start herefive fees, not one, and what 1% a year removes from thirty years of compounding.

Things that went wrong

• What happens to my money if my broker goes bust?Start herewhy the shares survive, why the cash is a different question, and which of your holdings are not assets at all.
• Why did my "capital protected" product lose money?Some background helpsfour ordinary reasons, all of them written into the document before you signed it.
• Can a fund stop me taking my money out?Some background helpsgates, suspensions and swing pricing: legal, disclosed, and triggered by exactly the conditions that make you want to leave.
• Why is my fund's return different from the index?Some background helpsusually the index version you were shown, not the fund doing anything wrong.

Things that are not what they sound like

• Why does a bond lose value when interest rates rise?Start herethe coupon is fixed, so only the price can move. How far it moves has a name and a number.
• What does leverage mean, and why is it dangerous?Start hereit multiplies the gain, the loss and the speed. The speed is what actually ruins people.
• What is the difference between an ETF and a fund?Start heremostly how you buy it. Underneath, often the identical portfolio.
• What does a credit rating actually tell me?Some background helpsone opinion about one question, and three things it deliberately does not say.
• Is a stablecoin actually stable?Some background helpsstable as long as everyone believes it is redeemable. That belief has failed before, at speed.

Deciding what to do

• How much should I put in any one thing?Start herethere is no correct number, but there is a correct question: what happens to the whole if this one goes to zero?
• Why is my money worth less even though it grew?Start herenominal against real, why cash loses quietly, and which investments actually track prices rather than merely being said to.

Not here?

The glossary defines the words, the learning paths put the pages in an order, and the search box — the magnifying glass in the header, or Ctrl-K — now searches the text of every page on the site, not just the titles. If a question keeps coming up and there is no page for it, that is a gap worth filling.
