Master the securities products the licensing exams live on — and the risks each one carries. Equity (common vs preferred stock, rights and warrants, ADRs, dividends and the ex-date), debt (corporate bonds, Treasuries, municipal bonds and their tax treatment, the price–yield inverse relationship, accrued interest, current yield vs yield to maturity), packaged products (mutual funds and NAV/POP sales-charge math, closed-end funds, ETFs, UITs, variable annuities, REITs), options (calls and puts — maximum gain, maximum loss, and breakeven for every basic position), and money-market instruments — plus the risk vocabulary that ties them together (market, credit, interest-rate, inflation, liquidity, and reinvestment risk). The math questions (options profit/loss, accrued interest, sales charges, yields) are computed with always-correct answers, and every wrong option is a classic exam trap.
