Core Concepts
Risk and return·Risk is uncertainty of future outcomes; return is the compensation for enduring it. Higher promised returns always mean larger swings.
Asset allocation·How you split money across cash, bonds, stocks and alternatives. It explains most of the long-run differences in portfolio outcomes.
Compounding is the most underrated variable: returns earn returns, and time widens the gap dramatically. Start early and avoid big mistakes.
The Allocation Pyramid
| Layer | Typical assets | Role |
|---|---|---|
| Cash | Deposits, money funds | Liquidity and safety |
| Bonds | Government and credit bonds | Stabilizer, lower volatility |
| Equities | Stocks, index funds | Main engine of long-run return |
| Alternatives | Commodities, property, private equity | Diversification and inflation hedge |
Diversification works because correlations are imperfect: a portfolio swings less than the sum of its parts. It is the only free lunch in investing.
A Six-Step Process
Set goal and horizon
Money needed in three years and money left for thirty years should not sit in the same assets.
Test risk capacity
Could you survive a 20% drawdown without losing sleep or selling in panic? Capacity beats appetite.
Fix strategic weights
Write down target percentages per layer and treat them as rules, not moods.
Diversify within layers
Spread across sectors, regions and durations — never a single bet.
Rebalance periodically
Reset weights yearly: it enforces selling high and buying low.
Review the process
Judge decisions, not just outcomes, so luck is never mistaken for skill.
