Asset allocation — how you split money between shares, bonds, cash and other classes — is the single most important decision in investing, explaining most of your long-term return and risk. Learn the risk-return spectrum of the asset classes, how allocation should shift with your time horizon, and the classic model portfolios.
Diversification is often called the only free lunch in investing — and correlation is the reason it works. Learn how correlation measures the way assets move together, why combining uncorrelated assets cuts risk without sacrificing return, the difference between systematic and unsystematic risk, and why correlations can fail you in a crisis.
You don't have to design a portfolio from scratch — decades of thinking have produced a handful of proven, ready-made models. Learn the classic 60/40, the elegant three-fund portfolio, the core-satellite framework, and target-date funds, and how to choose the one that fits your needs.
Left alone, a portfolio drifts away from its target as winners grow and losers shrink — quietly becoming riskier than you intended. Rebalancing restores the mix, and in doing so enforces a disciplined 'buy low, sell high'. Learn why portfolios drift, the main rebalancing methods, and how to do it tax-efficiently.
The right portfolio depends on the person holding it — and two factors matter most: how much risk you can bear, and how long until you need the money. Learn the crucial difference between risk tolerance and risk capacity, why a longer time horizon is the great risk reducer, and how to combine them into the right allocation.
A portfolio is far more than a pile of holdings — it's a system, and how the pieces fit together matters more than any single one. Learn what portfolio construction is, why the whole behaves differently from the sum of its parts, the core decisions it involves, and why your asset mix drives most of your long-term outcome.
Factor investing tilts a portfolio toward characteristics — value, size, momentum, quality, low volatility — that research links to higher long-run returns. Learn what factors are, why they may earn a premium, how 'smart beta' funds capture them, and the real risks: long droughts, crowding and data-mining.
A portfolio's return, on its own, tells you almost nothing — you have to know how much risk was taken to earn it. Learn to judge performance properly: total vs risk-adjusted return, volatility, the Sharpe ratio, maximum drawdown, benchmarking, and the difference between alpha and beta.
Modern Portfolio Theory turned diversification from folk wisdom into mathematics — and gave us the efficient frontier, the set of portfolios offering the most return for each level of risk. Learn how MPT works, what the efficient frontier shows, why correlation is its engine, and the real-world assumptions that limit it.
Should your asset mix be a fixed long-term policy, or should you shift it to exploit market conditions? That's the strategic-versus-tactical debate. Learn what each approach means, the strong case for a strategic core, the temptations and dangers of tactical tilts, and why most investors should lean heavily strategic.
