What you can actually own
Stocks, bonds, cash, gold, commodities, listed property, crypto. What each one is for, what it does badly, and the belief most often attached to it that does not hold.
Every asset class does a job. None of them does every job.
These notes take them one at a time: what you own when you own it, why investors hold it, what it costs, and where the common story about it stops being accurate. Read them in any order. They do not depend on each other.
