In 1952, in the “Journal of Finance”, Harry Markowitz presented a theory that ultimately won him the Nobel Prize. It’s called Modern Portfolio Theory and it has been the bedrock for how financial institutions have built their portfolios for the past 50 years. But new research is now telling us that this industry bedrock concept for building a portfolio is nothing more than theory, and it turns out to not actually work in the marketplace.

Modern Portfolio Theory (MPT) requires a basic assumption, that over time, higher risk positions pay a higher return. Yet research throughout the world is providing evidence that the reverse is actually true.
“Veteran quantitative investment analyst and economist Robert Haugen studied every stock market in the world from 1990 to 2011 and found that the average return of the least volatile stocks outperformed the most volatile stocks by an average of 17 percentage points. We found that in every one of the world’s markets, higher volatility equals lower returns, Mr. Haugen said. Does this fly in the face of modern portfolio theory? You’re damn right it does.”
In previous posts, I’ve highlighted a ground-breaking study from the Putnam Institute (https://content.putnam.com/literature/pdf/PI001.pdf) that discusses how retirees should have no more than 25% of their portfolio in the stock market due to the fact that the extra potential returns are not worth the risk. When the Institute’s director, W. Van Harlow, was interviewed on the results of this study, he was quoted as saying that historically, when it came to asset allocation, portfolio managers were “just guessing”.
Well, this latest research seems to agree with Mr. Harlow.
Here’s the part that I find outrageous. You work hard all your life, you sacrifice to save some money. Over many years you finally build a nest egg so that you can achieve some measure of financial comfort in your older age. You turn over the management of your money to who you assume are professionals, and then we find out that these same professionals are basically investing your money in ways that are not proven. They are “just guessing”.
Don’t you deserve better than that?
I believe that this is a big part of what is fueling the tidal wave coming down on Wall Street. Through their actions, they think it’s ok to experiment with your hard-earned dollars. And when it goes wrong, like it did in 2008, they wash their hands and admit no fault. They don’t pay, you do.
And I believe you do deserve better.
