What Is It?
Asset allocation is the process of dividing investments among different asset categories—stocks, bonds, cash, real estate, and alternatives. It is widely considered the most important determinant of portfolio returns and risk.
Origin
Modern asset allocation theory emerged with Harry Markowitz (1952) and the development of Modern Portfolio Theory. The Brinson, Hood, and Beebower study (1986) demonstrated that allocation explains over 90% of portfolio return variation.
Why It Matters
Asset allocation drives long-term returns more than security selection or market timing. Proper allocation balances risk and return based on investor goals, time horizon, and risk tolerance. It is the foundation of portfolio construction.

Market Mechanics
Strategic allocation sets long-term targets based on risk-return objectives. Tactical allocation makes short-term deviations based on market views. Dynamic allocation adjusts systematically to market conditions. Rebalancing maintains target weights. Correlation and volatility affect diversification benefits.
How It Behaves
Asset classes have different risk-return profiles and perform differently in various economic regimes. Stocks offer growth but high volatility. Bonds provide income and stability. Alternatives add diversification. Correlations rise during crises, reducing diversification when most needed.
