What to Make of 10-Year Small-Cap and Value Results

Ken French’s recently updated global factor data shows the global size and value premiums were basically flat for the past 10 years (the value premium was actually about –1 percent per year over this span). This long-term historical result has surprised many people and naturally led some to ask whether these premiums can be expected in the future. Figure 1 graphs the one-, three-, five-, 10-, 15- and 20-year average size and value premiums using the global data set.

Over the full annual history of the size and value data in the U.S., the size premium has averaged 3.4 percent per year with 14 percent volatility, while the value premium has averaged 5.0 percent per year with 14.1 percent volatility. These equate to Sharpe Ratios of 0.24 and 0.36, respectively. This also means that it can be expected for these premiums to be flat in (very) roughly 20 percent of 10-year periods (or, more precisely, in about 20 percent of 10-year periods for the size premium and 15 percent for the value premium). While 10-year periods such as 2006–2015 shouldn’t happen frequently, one 10-year stretch like this within an investment lifetime is well within the realm of possibility. And it’s important to emphasize that periods like these don’t prove the premiums have disappeared precisely because they are well within the realm of possibility.
