MARTINEZ, Carlos E.; LEDESMA, Juan S.  e  RUSSO, Alfredo O.. Calculating beta models to apply in Capital Asset Pricing Model: The case of Argentina. estud.gerenc. [online]. 2014, vol.30, n.131, pp.200-208. ISSN 0123-5923.

Using a literature review, four methods are applied for calculating betas in a sample of eleven companies that, between 2010 and 2012, were listed on the Stock Exchange of Argentina. Using each method, it was identified that one can be relied upon to determinate the betas of Small Business not quoted on the Stock Exchange. It is concluded that to calculate the beta values and interpret the risk of each company, it is technically necessary to analyze the method used and the variability of the time series used, as well as having knowledge of the future prospects of both the company analyzed and the industryto which it belongs.
