This document discusses traditional and modern approaches to portfolio construction. The traditional approach involves determining objectives, analyzing investor constraints like income needs and liquidity, determining the objective such as current income or capital appreciation, and selecting securities and their weights to minimize risk and maximize return. It involves four to six steps including analyzing constraints, determining objectives, selecting the portfolio, and considering factors like asset mix, growth, capital appreciation, safety, and diversification. The modern approach exemplified by Markowitz focuses more on risk and return analysis to minimize risk and maximize profit without considering individual needs.
