摘要：During the financial crisis 2007-2009 with certain impacts on the Viet Nam economy and especially, the stock exchange, there is un-diversifiable risk that influences the whole computer and electrical industries. Hence, the risk re-estimation for the listed firms in these industries becomes necessary. First of all, by using quantitative and analytical methods to estimate asset and equity beta of four (4) groups of listed companies in Viet Nam electrical, software, hardware and telecommunication industries with a proper traditional estimating model, we found out that the beta values, in general, for most companies are acceptable, excluding just a few cases. There are 88% of listed firms with lower risk, among total 64 firms, whose beta values lower than (<) 1. Secondly, through comparison of beta values among three (3) above industries, we recognized there are still 13% of total listed firms in the above group companies with beta values higher than (>) 1and have stock returns moving more than the market benchmark. Ultimately, this paper generates some results that could provides both internal and external investors, financial institutions, companies and government more evidence in establishing their policies in investments and in governance.
