Asset allocation involves diversifying investments across different asset classes such as equities, fixed income, gold, real estate, and commodities. Since different asset classes perform well at different times, diversification helps to ensure positive returns from some asset class at all times. This is similar to how Emirates Airlines diversifies its flight staff across different languages to serve a diverse customer base. Proper asset allocation is therefore essential to financial planning as it is the starting point for designing an investment portfolio that aims to perform well under different market conditions.
