Testing the Capital Asset Pricing Model (CAPM) in the Vietnamese stock market: an analysis of two sub-periods from 2006 to 2016

Objectives The main objective of this study was to explore the relationship between the beta values of stocks and its actual returns in order to investigate CAPM validity in Vietnamese stock market in the last 10 years. The study also aims to provide investors with fundamental knowledge of this basic financial modelling technique therefore to contribute in helping them evaluate investments effectively. Moreover, the research attempts to provide some beneficial contributions to the study of the application of the CAPM. Summary To achieve the purpose of the study, the researcher collected historical daily/weekly/monthly stock prices in order to estimate the correlative beta values over two five-year periods in Vietnamese security market. The linear relationship of these rate of returns with betas was tested by conducting the simple regression analysis. The research implications were disclosed relying not only on previous literature but also on empirical findings. Conclusions The results of the thesis reject the positive linear relationship between beta and returns. That means, based on the main findings of the research, the CAPM model is not valid in the Vietnamese market from 2006 to 2016

Methods of using character and language in stories to teaching Vietnam history from 10th century to 18th century in high school

ECONOMIC RELATIONS BETWEEN VIETNAM AND THE SOVIET UNION (1986-1991)

On November 3, 1978, Vietnam and the Soviet Union signed the Treaty of Amity and Cooperation, signaling a fresh and significant development in many domains, both in breadth and depth, which had a significant impact on the development of the two countries. This is seen as a "golden period" in particular for business connections between Vietnam and the Soviet Union. When both Vietnam and the Soviet Union began the process of "reforming" and "renovating" their respective nations in 1986, the two nations' economic connections continued to experience qualitative advancements. Vietnam was able to begin the process of rehabilitation and national construction with a strong economic foundation thanks to the Soviet Union's backing and aid during the years 1986 to 1991.  Article visualizations

Antibacterial activity of Piper betle extracts on Helicobacter pylori and identification of potential compounds

Helicobacter pylori is one of the most common infectious bacteria in the world that causes gastric diseases leading to cancer. The increase of multiple antibiotic resistance rates of H. pylori have been reported worldwide. Thus, development of novel drugs is urgently required. Piper betle has many therapeutic values in traditional medicine. In this study, therefore, we investigated antibacterial activity of P. betle extracts and their fractions against a H. pylori strain isolated in Vietnam. The agar disk diffusion assay showed inhibition zone of ethyl acetate extract and methanol extract from P. betle leaf that of were 46 mm and 32 mm in diameter, respectively. After fractionation of the ethyl acetate extract through silica gel column chromatography, two peaks, PD2 and PD3, out of 12 fractions showed the strongest antibacterial activity. PD2 was sub-fractionated further by re-chromatography on the silica gel column, and subfraction TK12 gave best resolution on LC-MS analysis. Finally, 4 potential compounds, quercetrin, calodenin B, vitexin and plicatipyrone, were identified in TK12 fraction.

Factors contributing to animal health risks: Implication for smallholder pig production in Vietnam

In Vietnam, there are about four million households producing pigs of which more than half are producing at small scale, i.e., about one to two pigs per production cycle. One of the most critical constraints to pig production, especially for small scale, is the presence of animal disease. Many types of diseases have been reported by smallholder pig producers in Hung Yen such as diarrhea, pneumonia, fever, blue ear, head edema and pasteurellosis. The percentage of sick pigs is highest among piglets (27 percent), as compared with growing pigs and fatteners (five percent each). Diseases could lead to death of pigs, resulting in economic losses to the pig producers. Estimates of the cost of mortality in pig production in Hung Yen were about 3.3 million VND per household, accounting for about 13.6 percent of total income from pig production. Results of this study suggest that there are some practices that contribute to mitigating disease risk and those practices can be easily applied at small scale of pig production. These practices are related to applying a suitable production scale, isolating different age classes of pigs, designing pig houses and using specialized livestock farming tools and sanitation. The value of losses avoided from the above practices is estimated at 320.3 USD per household per year

Entrepreneurship Education in Vietnamese Universities: Multi-Dimensional Approach From Economic Law and Human Rights

Entrepreneurial spirit and issues of digital division have linked to SDGs 4 and 8.
