Eugene F. Fama and Kenneth R. French introduced their three-factor design enhancing the capital possession rates design (CAPM) almost three decades back. They proposed two elements in addition to CAPM to describe property returns: small minus big (SMB), which represents the return spread between little- and large-cap stocks, and high minus low (HML), which determines the return spread in between high book-to-market and low book-to-market stocks.
So how well has Fama and Frenchs five-factor design discussed returns over the years? According to our analysis, only one factor has really held up over all time durations.
The SMB or size aspect carried out very well up to about 1982, creating returns of about 600% over the time period. Then from 1982 to 2000, the pattern reversed and large-cap stocks outshined little caps. The factor rebounded a bit afterwards but has mostly stagnated over the last 10 or 15 years.
To gauge an elements performance, we constructed a $1 portfolio and after that tracked its growth as if we were an investor going long on the aspect in question. For example, the SMB portfolio represents $1 bought 1926 in a portfolio that is long a basket of small-cap stocks and brief among large-cap stocks.
Fama and Frenchs initial framework has actually considering that undergone numerous modifications and evolutions as other researchers included their own elements and put their own spin on the duos insights. For their part, Fama and French upgraded their design with 2 more elements to additional capture property returns: robust minus weak (RMW), which compares the returns of firms with high, or robust, running profitability, and those with weak, or low, running profitability; and conservative minus aggressive (CMA), which determines the difference between companies that invest strongly and those that do so more conservatively.
SMB Cumulative Returns
The HML elements plight is well documented. Value investing– purchasing high book-to-market companies and shorting their low book-to-market peers– had a historic run from 1926 to 2007. Over this time frame, a long-short HML portfolio produced over 4000% returns.
The tide has actually turned. Considering that 2007, the results have entirely turned. Following the Great Recession, this exact same long-short portfolio lost about half of its worth as development stocks removed. Numerous have actually composed the value elements obituary.
International markets have actually gone through lots of an advancement since the Roaring 20s. If we accept Occams razor that the easiest description is frequently the likeliest, Clifford Asnesss theory might have the most appeal: “There Is No Size Effect.”
HML Cumulative Returns
But Robert D. Arnott and his co-authors have offered a different story: “Reports of Value Death May Be Greatly Exaggerated.” They attribute the value elements current underperformance to two phenomena: the HML book-value-to-price definition, which they contend does not sufficiently represent intangible properties, and the plunge in valuations of value vs. growth stocks.
Support companies that invest conservatively worked well for more than 40 years. In particular, since 2013 the stocks of firms that invest aggressively have just netted 20% excess returns.
CMA Cumulative Returns
As Jason Hsu, Vitali Kalesnik, and Engin Kose have written, the meaning of quality has shown rather malleable, however “Profitability and investment-related characteristics tend to capture the majority of the quality return premium.”
Which brings us to the quality element, or RMW. RMW is the single factor that has regularly delivered excess returns. Over all economic cycles since 1963, going long high quality stocks, or rewarding companies, and shorting their low quality, unprofitable equivalents has been an excellent financial investment method. And the power of the aspect has not diminished.
RMW Cumulative Returns
Still, the crucial lesson of Fama and Frenchs five-factor design and recent market history is simple if not specifically revelatory: Investing in rewarding business has been a noise and tried and true technique.

Of course, when Fama and French proposed their three-factor model, the hunch was that the SMB and HML aspects would regularly provide value gradually just as the RMW has. That hasnt worked out. Whether RMW continues to be the gem element that always delivers excess returns moving forward stays to be seen. Its worth remembering that often this time actually is different.
