Long-Term Memory in Stock Market Prices

Abstract
A test for long-run memory that is robust to short-range dependence is
developed. It is an extension of the "range over standard deviation" or
$R/S$ statistic, for which the relevant asymptotic sampling theory is
derived via functional central limit theory. This test is applied to
daily and monthly stock returns indexes over several time periods and,
contrary to previous findings, there is no evidence of long-range
dependence in any of the indexes over any sample period or sub-period
once short-range dependence is taken into account. Illustrative Monte
Carlo experiments indicate that the modified $R/S$ test has power
against at least two specific models of long-run memory, suggesting that
stochastic models of short-range dependence may adequately capture the
time series behavior of stock returns.
