Abstract
Factor portfolios derived from phenomena identified in the cross-section of stock returns have become vital parts of modern investment products and financial models. Even though much has been learned about the properties of these portfolios in recent years, one issue still remains unaddressed. Are factor returns long-range dependent (LRD)? We seek to answer this important research question because if factor returns were LRD, optimal portfolio decisions and traditional asset pricing methods/tests based on these factors would be severely biased and the validity of a large strand of prior research would be compromised. Specifically, using Hurst exponent approaches within rescaled range and detrended fluctuation frameworks, we analyse the presence of LRD in the returns of factor portfolios formed based on size, book-to-market, momentum and beta characteristics. For the periods from 1931 to 2014 (US market) and 1990 to 2014 (20 international markets) and supported by several robustness checks, we find no systematic evidence of persistence or anti-persistence in the factor returns. This implies that the factor use can be considered unproblematic in both asset management and asset pricing.

Notes
1 We use the term ‘factor returns’ because we do not wish to take sides in the debate about whether they are anomalous returns or represent premia compensating for certain types of risk.
2 Also, note that the conclusions of some tests of the efficient market hypothesis or stock market rationality also hang precariously on the presence or absence of long-term memory (see Merton 1987).
3 A typical example of LRD is given by Granger-type fractionally differenced (FD) time-series models (see Campbell et al. 1997). Consider an AR(1) series with slope ϕ=0.5 and a FD series with differencing parameter κ=1/3. Although both series have first-order autocorrelation of 0.500, at lag 5 (10, 25) the AR(1) correlation is 0.031 (0.001, 0.000) whereas the FD series has correlation 0.295 (0.235, 0.173), declining to only 0.109 at lag 100.
5 There are some online sources offering international factor returns (e.g., the data library of Kenneth French). However, they often do not provide the beta factor and also do not cover as many countries as we do.
6 Individual issues are assigned to markets based on the location of the primary exchange. For companies traded in multiple markets, the primary trading vehicle identified by Compustat/XpressFeed is used.
7 Book equity is obtained as shareholders’ equity minus the preferred stock value (PSTKRV, PSTKL or PSKT depending on availability). Shareholders’ equity is measured by stockholders’ equity (SEQ) or, if not available, the sum of common equity (CEQ) and preferred stocks (PSTK). If both SEQ and CEQ are unavailable, shareholders’ equity is proxied by total assets (TA) minus the sum of total liability (LT) and minority interest (MIB).
8 For firms with fiscal year ending in December this approach of Asness et al. (2013a) delivers the same measure as in Fama and French (1992). For firms with fiscal year not ending in December, prices at the fiscal year end date are used while Fama and French (1992) use December prices for all firms.
10 For US securities, the size breakpoint is the median NYSE market equity. For international securities, it is the 80th percentile by country.
12 The momentum breakpoints are the 70th and 30th percentiles.
13 This choice of countries is motivated by a focus on developed markets listed in the MSCI market classification (see https://www.msci.com/market-classification). Some developed markets (Israel and Portugal), emerging markets and frontier markets in the MSCI classification cannot be considered because of insufficient sample sizes.
14 Note that the tail behaviour of this kind of GARCH specifications often remains too short (see Bollerslev and Wooldridge 1992). However, this is no disadvantage for our analysis because RRA is robust to heavy tails.
15 While this is the most frequently used procedure, there are also versions that differ in the sub-sample (distinct vs. overlapping) and scatter-plot construction (averages vs. all points) (see Mielniczuk and Wojdyłło 2007).
18 These intervals refer to minimum sub-sample sizes of n m i n >50. However, they are also good approximations for smaller n m i n . Detailed values for other sizes and confidence levels are tabulated in Weron (2002).
19 This is why a new strand of the literature seeks to construct new types of size factors that may revive the size effect. One prominent example in this field is the size factor of Asness et al. (2015). Its main idea is to control for ‘junk’, i.e., stocks of companies that are small, have low average returns and are typically distressed or illiquid.
20 For the sake of brevity, we do not report the filter results. However, they are available upon request.
21 Switching to a 95 % confidence interval causes a few breaches. However, a picture of insignificant LRD in most time-windows remains.
22 Note that Weron (2002) also constructs his simulated confidence intervals for the PRM and finds that the resulting values are close to the classic normality-based interval of the method.
24 To back up this result, we have extended the study of Kristoufek (2012), which compares the performance of various Hurst exponent approaches in a variety of different memory and distribution settings, by our filtered procedure. Our results show that (i) non-normal GARCH residuals do not bias the H estimator and that (ii) the application of the filter leads to more precise estimates (in terms of a lower mean absolute error) of the population H than the estimator of Lo (1991).
25 If one interprets cross-sectional effects as market anomalies, absence of long memory in factor returns does not imply efficient markets because the performance of the portfolios still originates from abnormal predictability.
