Abstract

Purpose – The purpose of this paper is to provide some insights into the exchange rate exposure of Australian stock returns. 

Design/methodology/approach – Using a dynamic econometric approach that allows for both asymmetry and timevarying risk exposures in both the exchange rate variable and the market variable, a large sample of Australian firms were tested over the period of January 2001 and December 2005. The data were analysed using three different classification methods, forming portfolios according to industry sector, size deciles, and censoring deciles. 

Findings – Although the evidence of exchange rate exposure is limited across the sample of industries, the following were found: a timevarying asymmetric effect primarily in the utilities sector, timevarying exposure in the materials and energy sectors, and an asymmetric effect in the technology sector. Further, some timevarying asymmetric exchange rate exposure was found across most size and censoring deciles and also substantial evidence of a positive asymmetric effect in the market beta across all three classification methods. 

Originality/value – This approach varies from previous studies in this area that only allow for asymmetry and time variation in exchange rate exposures. The paper also examines the Australian stock market, a market which has not been extensively tested in this area of empirical research.
