Basics

Investing fundamentals in plain English — simple enough to learn and teach at the same time.

15 guides

Plenty of parents open an account for their kid while quietly hoping nobody asks them what a mutual fund is. That's a reasonable place to start, and it's who these guides are for.

Everything here is explained twice over: clearly enough that you follow it, simply enough that you can repeat it at the dinner table. What the stock market actually is. Why compound interest does something remarkable if you leave it alone. What inflation quietly does to money in a jar. How bull and bear markets got their names.

No jargon we don't define, no assumed background, and the glossary covers any term that needs one line. The goal isn't to make anyone an expert — it's to get you where your kid's questions feel like good ones instead of hard ones.
