The goal of this paper is to examine the impact of an overall market factor,
the factor related to the firm size, the factor related to the ratio of book
to market value of companies, and the factor of liquidity risk on expected
asset returns in the Serbian market. For this market we estimated different
factor models: Capital Asset Pricing Model (CAPM by Sharpe, 1964),
Fama-French (FF) model (1992, 1993), Liquidity-augmented CAPM (LCAPM) by Liu
(2006), and combination LCAPM with FF factors. We used daily data for the
period from 2005 to 2009. Using a demanding methodology and complex dataset,
we found that liquidity and firm size had a significant impact on equity
price formation in Serbia. On the other hand, our results suggest that the
factor related to the ratio of book to market value of companies does not
have an important role in asset pricing in Serbia. We found that Liu?s two
factor LCAPM model performs better in explaining stock returns than the
standard CAPM and the Fama-French three factor model. Additionally, Liu?s
LCAPM may indeed be a good tool for realistic assessment of the expected
asset returns. The combination of the Fama-French model and the LCAPM could
improve the understanding of equilibrium in the Serbian equity market. Even
though previous papers have mostly dealt with examining different factor
models of developed or emerging markets worldwide, none of them has tested
factor models on the countries of former Yugoslavia. This paper is the first
to test the FF model and LCAPM with FF factors in the case of Serbia and the
area of ex-Yugoslavia.
