Before any fund is chosen, the investor has to be ready to invest and the portfolio has to fit the person. This chapter covers the foundations (emergency cash, insurance, manageable debt), investment objectives, the constraints that shape a portfolio (time horizon, liquidity, risk capacity and tolerance, tax, legal limits, personal preferences, inflation, knowledge), and the tools that turn them into a portfolio: strategic and tactical asset allocation, core-satellite, diversification, rebalancing, dollar-cost averaging, investment approaches, borrowing to invest, behavioural biases and review. Expect scenario questions that ask what fits a named client, and calculations on rebalancing trades, average cost per unit and geared returns.

Must-know for the exam
✓Foundations first: emergency cash, insurance protection and manageable debt. Invest what remains after emergency savings, household expenses, insurance premiums and loan repayments (MoneySense).
✓MoneySense Basic Financial Planning Guide (as at 13 Sep 2026): emergency funds of at least three to six months' worth of expenses; invest at least 10% of income for retirement and other goals.
✓Objectives: growth (early career, equity-oriented), income (bonds and dividend shares), capital preservation (near or in retirement), total return (balanced mix of growth and income).
✓Longer horizon: more time to recover from falls and to compound, so more growth assets. Short-term needs: low-risk, liquid products such as Singapore Savings Bonds.
✓Risk profile = risk capacity (financial ability to bear loss) and risk tolerance (attitude). Where they conflict, the LOWER one governs.
✓Tax (IRAS, as at 13 Sep 2026): no tax on capital gains; one-tier dividends from Singapore-resident companies are tax-exempt for shareholders; no withholding tax on dividends.
✓Real return = (1 + nominal) / (1 + inflation) - 1. Required nominal = (1 + real)(1 + inflation) - 1, e.g. 3% real at 2% inflation needs 5.06%.
✓Strategic allocation = long-run policy mix. Tactical allocation = temporary tilts around it on a market view, within set ranges. Asset allocation drives most of a diversified portfolio's return variability.
✓Core-satellite: a low-cost diversified core plus smaller active or thematic satellites. Blended cost is the weighted average of the fees.
✓Diversify across asset classes, sectors, countries, issuers, currencies and time. It reduces but cannot eliminate risk; overlapping funds add cost for little benefit.
✓Rebalancing: new weight = value of asset after returns / new total. Trade = target % x new total - current value. It sells relative winners and buys relative losers.
✓Calendar rebalancing trades on fixed dates; threshold rebalancing trades when a weight leaves its band. New cash can be directed to the underweight asset instead of selling.
✓Dollar-cost averaging: fixed sum at regular intervals. Average cost per unit = total invested / total units, which is at or below the simple average of prices (equal only if every price is the same).
✓DCA does not guarantee a profit or prevent loss in a steadily falling market; in a steadily rising market a lump sum invested at the start tends to do better.
✓Margin: return on own capital = (price gain - interest) / own capital. Margin call when (value - loan) / value falls below the maintenance ratio; losses can exceed the cash put in.
✓Biases: overconfidence (overtrading), loss aversion, disposition effect (sell winners early, hold losers), herding, anchoring, recency, confirmation. A written plan with rules counters them.
Before you invest: foundations and objectives
•Examiners start with readiness. A client who invests without a cash buffer, protection or control of debt may be forced to sell at a loss when something goes wrong, whatever product is chosen.
•MoneySense sets the order: provide for emergency savings, household expenses, insurance premiums and loan repayments, and invest what remains. Its Basic Financial Planning Guide (as at 13 Sep 2026) suggests emergency funds of at least three to six months' worth of expenses.
•Next, turn vague aims into goals with an amount and a date. That fixes the horizon and tells you the return and risk needed.
•Growth: build capital; equity-oriented, higher return and risk; suits early career investors.
•Income: regular cash flow from bonds and dividend-paying shares; moderate risk.
•Capital preservation: protect the principal; lower-risk fixed income; suits those near or in retirement.
•Total return (balanced): a mix of growth and income with moderate price swings.
•Trap: a scenario with expensive credit card debt and no emergency fund. The answer is to clear the debt and build cash first, not to invest because equities might beat the card interest.
•Takeaway: cash buffer, protection and debt control first; then a goal with an amount and a date; then an objective.
The longer the horizon, the more time there is to ride out falls and let returns compound, so more growth assets can be held (MoneySense). Money needed soon belongs in low-risk, liquid products such as Singapore Savings Bonds, which as at 13 Sep 2026 can be redeemed in any month with no penalty.
•A liquidity need is a requirement to raise cash quickly without a large loss of value. Different goals have different horizons, so a near-term sum can be ring-fenced in liquid assets while the rest stays invested for the long term.
•The risk profile has two parts:
•Risk capacity: the financial ability to bear loss. Driven by income stability, wealth, dependants, debts and horizon.
•Risk tolerance (willingness): the investor's attitude to losses and volatility. Shown by anxiety, stated preferences and past panic selling.
•Where they conflict, the lower one governs. MoneySense puts it simply: risk appetite is more about how much you can afford to lose than how much you want to make. Capacity usually falls near retirement because less time and income remain to recover from a loss.
•Trap: a wealthy client with a low tolerance. Strong finances do not override the attitude; set the profile by the lower of the two. Also, past panic selling is evidence of tolerance, not capacity.
•Takeaway: horizon sets how much volatility is affordable; capacity and tolerance both count, and the lower one wins.
