This study estimates market risk of total 45 listed companies in Viet Nam public utilities, natural gas and oil industry during the financial crisis period 2007-2009. Firstly, we found out in the research sample that there are 82% of firms, of total listed firms, with beta values lower than (<) 1, meaning with lower risk, and the systemic risk is acceptable. Secondly, there are 11% among total 45 listed firms, whose beta values higher than (>) 1, meaning having stock returns fluctuating more than the market benchmark. Thirdly, among three (3) groups, the systemic risk in the electric power industry is the smallest, shown by estimated values of equity and asset beta mean, and asset beta variance in this industry is also the smallest. Finally, this paper generates some analytical outcomes that enable companies and government to have more evidence in establishing their policies in investments and in governance.
