Please readNot financial advice
This site and book are general educational information only. They explain how money, markets, institutions, and wealth work in plain language. They are not financial, investment, legal, or tax advice, and nothing here is a recommendation to buy, sell, or hold any investment.
Markets carry risk. Prices and the value of any asset can fall as well as rise; past performance never guarantees the future. Figures, rankings, and examples are approximate, simplified for teaching, and were accurate only at the time of writing. All amounts are in US dollars unless shown as S$ (Singapore dollars).
Do your own research and, where appropriate, consult a licensed professional. Company, fund, and product names appear for explanation only and do not imply any endorsement. Written for readers aged about 13 and up.
