Sažetak

In this study, the relation between the coal firms that are traded in New York Stock Exchange
and S&P500 index is analyzed. The return of the coal firms and the market return are analyzed by
using traditional CAPM and two-state Markov regime switching CAPM (MS-CAPM). According to
the Likelihood Ratio test, two-state regime MS-CAPM gives better results and indicates a non-linear
relation between return and risk. It is found that beta shows variability in regard to low and high
volatile periods making linear CAPM to provide deviated results.
