An analysis of the capital asset pricing model in the Egyptian stock market

This paper offers evidence confirming the validity of applying modern portfolio theory and capital asset pricing models to the emerging stock market of Egypt. The results indicate that market risk, as measured by beta and preference for skewness, seems to play a significant role in the returns dynamics in the Egyptian stock market. There is a significant and positive premium for companies with positive skewness. With regard to the return-risk trade off, the results indicate that a portfolio that was based on consumer staples and financial companies (mainly banks) with low betas had outperformed a portfolio containing construction, materials, hotels, and weaving companies with larger betas. Historically, the government's nationalizations that took place, between the mid fifties to the mid sixties, had adversely affected companies in the industrial and construction sectors more than consumer staples companies and banks. This could explain why lower beta companies were observed more in consumer staples, banks, and pharmaceuticals. (C) 2006 Published by Board of Trustees of the University of Illinois.
