In this paper, we explore the relationship of firm-size and book-to-market equity with stok returns and with firm-specific and macro-economic fundamentals in the Istanbul Stock Exchange (ISE). We apply two different popular asset pricing models, the one factor CAPM and the three-factor Fama and French (1993) model, to individual stock returns and to size/book-to-market sorted portfolios. We find both size and book-to-market effects to be significant, but the size effect has a higher explanatory power. We also evaluate additional firm-specific risk characteristics of our extreme portfolios and their returns in different states of the Turkish economy and relate the size and book-to-market related Fama and French factors to macro-economic indicators. Our results reveal some new empirical regularities in the ISE and support the Fama and French findings to justify models for additional risk factors in returns.
