As a systematic risk parameter, the beta (β) coefficient shows the relation between stock and market. The aim of this study is to estimate the future value of beta coefficient. Accordingly, utilizing with the daily data, historical beta coefficients for 74 common stocks of Istanbul Stock Exchange (ISE) is computed on monthly quarterly, semiannually and annually for the period 2003 – 2011. Afterwards the panel unit root tests proposed by Levin, Lin and Chu (2002) and Im, Pesaran and Shin (2003) is employed to reveal if the betas are on a random walk. Meanwhile pooled regression analysis and limit theorem is utilized to estimate the future value of betas. The results of the study indicate that betas are not on random walk and they are on mean reversion. Consequently the expected beta result seems to increase with the increase in the period. These results could be considered as investing to the stock where betas under mean value for investors
