Tips for Using Academic Research About Investing

There is a constant stream of new academic research about investing. Some of the papers attempt to explain the key drivers of returns. Some are more focused on investor behavior. Many papers are focused on realizing higher returns (“delivering alpha”). For an investor seeking new ideas, these papers can range along a spectrum from being very helpful to being completely useless to being somewhere in between. It depends on the paper and what specifically a person is looking for.

There are many of us who cite this research regularly. Larry Swedroe does so regularly on ETF.com. Jason Zweig often tweets out links to research. It’s also not unusual to see him reference academic research in his Wall Street Journal column, The Intelligent Investor. I mention papers in this weekly commentary and in the Briefly Noted section of the AAII Journal. The three of us are not alone in writing about academic research related to investing.

I’ll get to sources in a moment, but first I want to add some cautionary statements. When it comes to drivers of outperformance, such as for selecting stocks, it’s impossible for individual investors to mimic the stated performance in papers. The returns are often presented in some form of good versus bad, where the stocks with the “good” traits are purchased and the stocks with the “bad” traits are shorted. Furthermore, the returns calculated are typically based on a very large number of stocks grouped by deciles (10 groups) or quintiles (5 groups) ranked according to what’s being tested (e.g., lowest to highest valuation.) It’s impossible for individual investors to implement such strategies. Due to liquidity constraints, it’s not easy for institutional investors to do so, either. There is a work-around, though.

The portfolio continues to buck the trend of small-cap and value-oriented methodologies as the Vanguard Small Cap Index fund (NAESX) climbed 0.8% for the month and the DFA US Micro Cap fund (DFSCX) added 1.6% in April. The Model Fund Portfolio added 0.6% in April, compared to a 1.0% monthly gain for the SPDR S&P 500 ETF (SPY).
