Savings & Investments
Core concepts
This domain covers the risk–return relationship, asset classes (cash, bonds, equities, property), diversification, and collective investments (unit trusts, OEICs, investment trusts). Candidates must know the difference between units vs. shares, bid/offer pricing, initial vs. ongoing charges, and accumulation vs. income unit classes.
Understand tax wrappers (ISA-type savings vehicles, pensions) and the tax treatment of interest, dividends, and capital gains. Know the time value of money: simple vs. compound interest, real vs. nominal returns (real = nominal − inflation), and the effect of charges over time. Also grasp risk profiling, suitability, and the principle that higher expected return requires accepting higher volatility.
Traps in questions
- Confusing unit trusts/OEICs (open-ended, priced by NAV) with investment trusts (closed-ended, share price can trade at premium/discount to NAV).
- Forgetting that past performance does not guarantee future returns.
- Mixing nominal and real returns; questions often ask for the real return after inflation.
- Overlooking the compounding drag of charges on long-term outcomes.
- Treating capital at risk products as guaranteed.
Worked example / rule of thumb
Rule of thumb: Rule of 72 - money doubles in roughly 72 ÷ annual return % years. At 6% it doubles in about 12 years. For real return: 8% nominal − 3% inflation ≈ 5% real (approximation; exact = (1.08/1.03) − 1 ≈ 4.85%).
When comparing funds, always compare net returns after charges, and check whether income is reinvested (accumulation) or paid out (income units).
