Introduction I first encountered Harry Markowitz’s Efficient Frontier Theory while studying portfolio optimization. The theory, introduced in his 1952 paper “Portfolio Selection,” revolutionized modern finance by quantifying the trade-off between risk and return. It laid the foundation for what we now call Modern Portfolio Theory (MPT). In this article, I break down the Efficient Frontier,

When I first encountered Markowitz Portfolio Theory, it struck me as one of those rare ideas that reshapes how we think about investing.
