This represents a set of optimal portfolios that offer the highest expected return for a defined level of risk. Portfolios falling below the efficient frontier are sub-optimal because they do not provide enough return for the amount of risk taken.

Robert Haugen was a pioneer of quantitative finance and a fierce critic of the Efficient Market Hypothesis (EMH) and the Capital Asset Pricing Model (CAPM). First published in the late 20th century, Modern Investment Theory was designed to provide a comprehensive overview of investment mechanics while simultaneously introducing behavioral and empirical counter-arguments to mainstream academic theory.

Haugen’s critique wasn't just theoretical; it was intensely practical. His empirical research uncovered the , showing that less volatile stocks consistently outperform more volatile ones. This is a clear violation of the CAPM's core prediction. He also documented other quantitative factors like value and momentum that can be used to build superior portfolios. In The New Finance , he showed how factor-based investing could reliably beat the markets using sophisticated regression analyses and a wide range of factors. His work paved the way for what is now a multi-trillion dollar industry known as factor or smart beta investing.
Robert Haugen’s Modern Investment Theory is far more than a dry collection of mathematical proofs. It is a critical, investigative look at the financial system. It teaches readers the elegant mathematics of Markowitz, Sharpe, and Lintner, but immediately arms them with the empirical tools necessary to question those very models.

Perhaps the most intellectually rigorous section of the book, Part III dives into the competing theories of how financial assets should be priced. provides a detailed examination of the Capital Asset Pricing Model (CAPM) , carefully distinguishing between its economic assumptions and its definitional properties. Chapter 9 presents "Empirical Tests of the Capital Asset Pricing Model," where Haugen's critical perspective begins to emerge as he presents evidence both for and against the model's validity. Chapter 10 explores the Arbitrage Pricing Theory (APT) as an alternative, multi-factor approach to asset pricing. Chapters 11 and 12 address the practical problem of "Measuring Portfolio Performance," both with and without the aid of formal asset pricing models.
