A sample answer to question 1

How do you construct a portfolio to meet a client's objectives, and how do you decide asset allocation?

Everything starts with the mandate: return target, risk tolerance, time horizon, liquidity needs, constraints and any ethical or tax considerations. For a discretionary client that comes from the suitability assessment and investment policy statement. I set a strategic asset allocation using long-run return, volatility and correlation assumptions, usually with mean-variance analysis as a guide but with constraints, because optimisers over-concentrate on estimation errors. Then I decide any tactical tilts based on valuations and the macro cycle, kept within agreed ranges. Within each asset class, I select funds or securities, thinking about diversification of risk drivers, not just names, so I'd review factor and currency exposure and downside scenarios. I'd test the portfolio against historical drawdowns and the client's capacity for loss, and set rebalancing rules, often by tolerance bands. I record the rationale, so that the portfolio can be explained and reviewed regularly.

Common mistake to avoid: Jumping to stock picks; ignoring client constraints
