      ? Ayman Bitar and W, " Book-to-Market, Size, and Industry Effect " , "Journal",Vol.3,No.2, International Journal of Economics and Finance, USA, 05/02/2011 :الملخص
      This paper aims to extend the paper by Saleh and Bitar (2009) by addressing whether variation in stock returns can be explained by differences in industry concentration. The paper concludes that firms operate in highly concentrated industries earn lower returns and less risk than those operate in highly competitive industries. Furthermore, the paper provides evidence to suggest that investors in Amman Stock Exchange cannot benefit from a trading strategy based on industry structure. Keywords: Book-to-market effect, Size-effect, Industry Effect, Three-factor model




      Ayman Bitar and Wali, " Book-to-Market, Size, and Distress Risk " , "Journal",Vol.6,No.5, Journal of US-China Public Administration, USA, 10/01/2009 :الملخص
      Fama and French (1992) argue that the book-to-market effect might be due to distress risk. Chan, Chen, and Hsieh (1985) show that a large portion of the size effect can be explained by a default factor. This paper examines the relationship between size and book-to-market effects and distress risk. The paper provides evidence suggesting that size and book-to-market effects are very importance in estimating the risk premium in Amman Stock Exchange (ASE). Furthermore, consistent with Dichev (1998) the paper concludes that the distress risk in unlikely to account for the size and book-to-market effects
