1. Explain the key mechanics: what a Stocks and Shares ISA is, the annual contribution limit, and the tax treatment (no income tax on dividends, no capital gains tax on growth or withdrawals).
2. Describe the three main investment choices for beginners: a global index fund (passive, low cost, broad diversification), a multi-asset fund (automatic rebalancing across stocks and bonds), and a robo-adviser platform (algorithm selects and manages a portfolio based on risk tolerance).
3. Explain the four factors to consider when choosing a platform: annual charges, fund selection, ease of use, and whether there is a minimum contribution requirement.
4. Describe the most important thing a beginner investor should understand about volatility: short-term price falls are normal and expected; selling during a fall turns a paper loss into a real one.
