StrikeAndYield
Financial products explained — from the first sentence to the pricing formula.
An atlas of financial products: 129 instruments across eleven asset classes, each explained at five depths, with 142 calculators and a 303-term glossary.
What it does
Writing about financial products is usually either too simple or assumes too much — little sits in between. StrikeAndYield therefore layers five levels: snapshot, beginner, intermediate, advanced, desk notes. You can stop at any of them and still have a whole answer. Eleven asset classes, from cash equities through rates and credit derivatives to digital assets; each has a deep-dive page with calculators whose inputs you can move yourself. Plus 13 guided routes through the atlas, 32 concepts and a glossary. The site is in English.
- 129 financial products across eleven asset classes
- Five levels of depth per product — snapshot, beginner, intermediate, advanced, desk notes
- 142 calculators in one place, plus an option strategy builder
- 303 terms in the glossary, 32 concepts, 13 guided routes
- Formulas properly typeset, fonts and libraries served locally
A taste
Four of 303 terms — verbatim
Taken from the glossary, unchanged. Four lines that show the tone the site explains in.
- TermThetaAn option's daily loss of value from time passing, all else equal. The rent option buyers pay and sellers collect.
- TermDrawdownThe fall from a portfolio's peak to its subsequent trough. The number investors actually feel: a 50 % drawdown needs a 100 % gain to recover.
- TermBasis riskThe risk that a hedge and the thing it hedges don't move identically. Hedging jet fuel with crude futures works — until the gap between them moves against you.
- TermYield curveYields plotted across maturities, from overnight to 30 years. Normally upward-sloping; inversion — short rates above long — is the market's classic recession signal.
Straight in
If you already know what you are looking for in StrikeAndYield
It fits you if
- You want to understand an instrument rather than merely recognise it — each one appears at five depths, from the snapshot to the desk notes
- You want to see the formula it is actually priced with, and move the inputs yourself
- You are comfortable reading in English
It does not fit if
- You are after recommendations or prices: this explains how an instrument works, not what to buy
- You want German explanations — the site is in English
Both lists are here because a product that fits everyone was made for no one.
How it is built
The way it is built, written down
What is inside StrikeAndYield is not only a promise here — it is described, with reasons and with what it costs.
Why a 50 per cent loss needs a 100 per cent gain
Losses and gains are not symmetric: lose half and you have to double your money to get back to even. The formula behind it, a table — and what follows from it.
Read the articleA privacy statement that does not fall behind the code
Almost every privacy statement is accurate on the day it is written and never again. The reason is not ill will but a missing connection — and that connection can be made.
Read the articleWhen a number means something — and when it is noise
A small website produces small numbers, and small numbers vary on their own. Read like large ones, they turn chance into a trend. How to tell the difference.

What visitors want to know before the first click.
What does “five levels of depth” mean?
Every instrument appears five times: a snapshot in two sentences, a beginner's account in ordinary language, an intermediate one with the mechanics, an advanced one with the pricing, and finally desk notes from a trading desk's point of view. You can stop at any level.
What is there so far?
129 instruments across eleven asset classes, from cash equities through rates and credit derivatives to digital assets; plus 142 calculators, a glossary of 303 terms and 13 guided routes.
Is this investment advice?
No. The site explains instruments and how they are valued. It makes no recommendation and knows neither your situation nor your goals.
