Securities Industry Essentials
Understand how capital markets function, how stocks, bonds, and funds trade, and the essential regulatory rules that protect investors.
Like Duolingo, but for Securities Industry Essentials. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
24 levels across 4 sections, about 48 minutes end to end, roughly 10 days at five minutes a day. It moves through Entering the Market: Equities and Debt; Diversifying and Hedging: Pooled Funds and Options; Executing Trades and Managing Client Accounts; and Navigating Rules, Economics, and Market Ethics. It starts from scratch.
