It’s been well-documented that, in equity investing, assets have earned premiums because they are exposed to the risks of a certain factor. Given that the literature provides us with a veritable factor “zoo” (there are more than 300), for investors to consider adding exposure to a factor, it should meet the following criteria: Persistent: It…
Robert Novy-Marx’s 2012 paper, “The Other Side of Value: The Gross Profitability Premium,” not only provided investors with new insights into the cross section of stock returns, it helped explain Warren Buffett’s superior performance—he bought value companies with higher profitability metrics. Key Findings About Profitability Novy-Marx’s study, which covered the period 1962 through 2010, used…
The world of finance and asset pricing used to be fairly simple. At first, there was just the single-factor capital asset pricing model, with market risk (beta) as the sole factor to explain the differences in returns of diversified portfolios. Over time, the working model evolved into a still relatively simple four-factor model, adding value,…
Hit by a “perfect storm” that combined a decade (2000-2009) in which the S&P 500 lost about 1% a year with a rising tide of pension obligations, public workers’ pension funds across the country increasingly began turning to riskier alternative investments (such as hedge funds) in an effort to boost returns and close the gaps…
As I’ve written about before, the goal of sustainable, or socially responsible, investing (SRI) can be characterized as “doing well by doing good.” The implication of such double-bottom-line investing is that you are seeking not only profitable investments, but also investments that meet your personal standards. SRI has gained a lot of traction in portfolio management in recent…
If investors were asked, “Who do you think is the greatest investor of our generation?” I’d bet an overwhelming majority would answer, “Warren Buffett.” If they were then asked, “Do you think you should follow his advice?” you might think that they would say, “Yes!” The sad truth is that while Buffett is widely admired,…
When I started writing books about a decade ago, I took the position that no one should rely on a broker for financial advice. My reasoning was simple. I had never met a broker who recommended a globally diversified portfolio consisting solely of low-management-fee index funds, exchange-traded funds or passively managed funds. It was my…
It has been well-documented that profitability is positively correlated with stock returns—firms with higher profits earn higher returns. The question that we will ask today about the profitability premium relates to its source: Is it based on risk? Or, is it an anomaly that results from persistent pricing errors? F.Y. Eric Lam, Shujing Wang and…
I’m getting more questions about what this election will mean for people’s personal financial situations than I’ve received in any previous election that I can remember. Financial advisers almost twice my age tell me the same thing. While I’m sure there are many reasons for these questions, I submit that the primary one is this:…
Money is an interesting actor that plays two roles in our lives. In the first, money equals money. It fits in a spreadsheet. It’s something to be calculated. In the other, money equals stories. It’s what we tell ourselves about our relationship with money. Let me share a story I’ve told myself. For six years,…
It seems that in the upcoming presidential election, American voters will be faced with choosing between two candidates with the highest unfavorable ratings in history. It’s either that (at least if the parties’ national conventions go as expected), or a choice not to vote. The unfavorable ratings of both candidates are creating a great amount…
For about three decades, the working asset pricing model was the capital asset pricing model (CAPM), with beta—specifically market beta—being its sole factor. Then, in 1993, the Fama-French three-factor model—which added size and value—replaced the CAPM as the workhorse model. By eliminating two major anomalies (the outperformance of small stocks and of value stocks), it…
Robo-advisors have had a significant — and generally positive — impact on the financial services industry. The term typically refers to services that use models and algorithms to invest client portfolios, often in exchange-traded funds (ETFs). A benefit much touted by some of these services is that there’s no interaction with a human advisor. The…
Perhaps you’ve heard the expression, “Only the paranoid survive.” Ring a bell? If so, it’s probably because that’s the title of a book by Andrew S.Grove, the former chairman and chief executive of Intel. When I read this book in late 1999, I bought into the need to always be looking for opportunities and to live my life…
