Robert A. Haugen's Modern Investment Theory (most recently updated in its 5th Edition
For decades, the bedrock of academic finance has been Modern Portfolio Theory (MPT) and the Efficient Market Hypothesis (EMH). Pioneered by luminaries such as Harry Markowitz and Eugene Fama, these theories posit that markets are rational, investors are utility-maximizing agents, and prices fully reflect all available information. Under this paradigm, the primary driver of a security’s return is its risk, typically defined as volatility or beta. However, the late Professor Robert Haugen emerged as one of the most vocal and data-driven critics of this established orthodoxy. Through his seminal work, most notably detailed in his book The New Finance: The Case Against Efficient Markets, Haugen constructed a formidable counter-argument. This essay explores Haugen’s critique of modern investment theory, analyzing his identification of market inefficiencies, the role of behavioral finance, and his compelling evidence that low-risk stocks actually yield higher returns—a phenomenon that fundamentally inverts the risk-return tradeoff.
