ABSTRACT
This paper provides evidence of a significant exchange rate effect on stock index returns using data from seven selected countries practicing free-floating exchange rate regimes. This research uses parity and asset pricing theories, thus placing it within the monetary-cum-economics framework for international asset pricing. In this study, we apply a system of seemingly unrelated regression to control for unobserved heterogeneity and cross-sectional dependence. The findings constitute evidence of a statistically significant exchange rate impact on stock index returns across selected countries. These findings can be considered as falling under the arbitrage pricing approach of the international capital asset pricing model of Solnik who also used the parity-theoretical framework on exchange rate determination.

Notes
1 A number of theories and models have been developed since the 1960s, for individual asset valuation purposes: Williams (Citation1938) for bond valuation and Harvey, Liu, and Zhu (Citation2016), provided a review on this perspective. Apart from an economy-wide impact, a segmented market impact also exists in the individual stock impact. Ariff and Khan (Citation1998) considered each capital market as consisting of separately priced asset clusters. Accordingly, it is possible to model pricing behaviour away from the embedded practice of analysing individual stocks and towards macro-level markets (the latter was attempted by King (Citation1966), who showed that 52 percent of share price changes are due to macroeconomic factors). Studies on aggregate level are few: De Santis and Gerard (Citation1998) and Dumas and Solnik (Citation1995).
2 In this revised version, the coefficients reported for all variables are from rechecking as pointed out during the review process. This variable was one of them that had a changed size.
3 We followed a generalization of the model to estimate the system of equations so that the standard errors of each equation are made to rely on the actual data by entering the mean equation while any generated regressor appear only as instruments from the first step estimation. This application led to significant improvements in our estimation by deriving standard errors, which are robust to some kinds of misspecifications.
