Serial correlations in the trading volume of the US stock market are investigated in this paper. The use of the detrended fluctuation analysis implemented within a rolling window indicated that, for the period 1929–2011, the strength of correlations exhibits important temporal variations with a trend shift by the 1990s, and 4-year and 21-year cycles. These empirical findings are compared to those obtained for mature international stock markets (FTSE-100 and Nikkei) and discussed in terms of potential economic and financial implications.
► Serial correlations in the trading volume for the US stock market are studied in this work. ► 4-year and 21-year cycles in the trading volume dynamics are detected. ► It is argued that these cycles are related to the effects of inventory (Kitchin) and investment (Kuznets) business waves.
