The Volatility of Market Risk In Groups of Viet Nam Listed Hotel and Tourism Company Groups during the Financial Crisis 2007-2009

The financial crisis 2007-2009 with certain impacts on the Viet Nam economy and especially, the stock exchange, has affected systematic risk in the whole hotel and tourism industries. Hence, it is the reason to perform the risk re-estimation for the listed firms in these industries. First of all, by using a proper traditional estimating model to estimate asset and equity beta of three (3) groups of listed companies in Viet Nam entertainment, tourism, and hotel industries, we found out that the beta values, in general, for most companies are acceptable, excluding just a few cases. There are 77% of listed firms with lower risk, among total 22 firms, whose beta values vary in a range from 0 to 1. Secondly, through comparison of beta values among three (3) above industries, we recognized there are still 18% of total listed firms in the above group companies with beta values higher than (>) 1and have stock returns moving more than the market benchmark. Last but not least, 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.
