Abstract:
Following its introduction in the seminal study of Osborne (1959), a voluminous literature has emerged examining the returns–volume relationship for financial assets. The present paper revisits this relationship in an examination of the FTSE100 which extends the existing literature in two ways. First, alternative daily measures of the FTSE100 index are used to create differing returns and absolute returns series to employ in an examination of returns–volume causality. Second, rolling regression analysis is utilised to explore potential time variation in the returns–volume relationship. The findings obtained depict a hitherto unconsidered complexity in this relationship with the type of returns series considered and financial crisis found to be significant underlying factors. The implications of the newly derived results for both the understanding of the nature of the returns–volume relationship and the development of theories in connection to it are discussed.
