At the same time, the study also evaluates current status of using and measuring the accuracy between Pooled OLS model, FEM, and REM.
Based on financial data and stock prices of 39 companies providing electricity from renewable energy resources listed on the Vietnam Stock Market during the period between 2016 and 2022, the author conducted multiple regression analyses of variables using the Feasible Generalized Least Squares (FGLS) to test the factors affecting stock price changes in the Vietnam Stock Market. Research results show that there are seven statistically significant impact variables to each model, which are: Company size (SIZE), dividends per share (DPS), earnings per share (EPS), financial leverage (LEV), price-earnings ratio (PE), gross domestic product growth rate (GDPG), and inflation rate (INF). In particular, company size (SIZE), dividends per share (DPS), earnings per share (EPS), and price-earnings ratio (PE) have the same effect, and the remaining variables have the opposite effect. Specially, the ii exchange rate variable (EXC) has a negative regression coefficient for stock price changes, but this variable is not statistically significant in the model.
Combining the results of the quantitative research method, the author provided suggestions and recommendations for investors and analysts on choosing and using models to make investment decisions in the Vietnam Stock Market, as well as advices for management agencies and businesses to improve the effectiveness of analyzing stock price fluctuations to increase corporate value sustainably. Simultaneously, the author also provided some limitations that the graduation thesis has not been able to resolve, then came up with directions for further research. Keywords: Stock price, changes, company size, dividends per share, earnings per share, financial leverage, price-earnings ratio, exchange rate, gross domestic product growth rate, inflation rate, electricity, renewable energy resources. iii DECLARATION OF AUTHENTICITY My name is Nguyen Thi Van Anh, class HQ8-GE05 under the guidance of lecturer Dr.
Luu Thu Quang with graduation thesis topic “Factors affecting stock price changes of companies supplying electricity from renewable energy resources listed on the Vietnam Stock Exchange.” The thesis is the author’s research work. The research results are honest, including no previously published content or content done by others except for fully cited citations in the thesis. I hereby declare and take full responsibility if any of the above is untrue! Ho Chi Minh, October 10th, 2023 Student Nguyen Thi Van Anh iv ACKNOWLEDGEMENT To complete this graduation thesis, I received the attention and help of Dr. Luu Thu Quang.
First of all, I would like to genuinely express my deep gratitude of Dr. Luu Thu Quang of Ho Chi Minh University of Banking in particular and to teachers from the Faculty of Banking and Finance in general for creating favorable conditions for me to carry out this research topic as well as enthusiastically imparting valuable knowledge helped me apply the theories I have learned into practice. With that valuable knowledge, I have presently completed my graduation thesis with the topic “Factors affecting stock price changes of companies supplying electricity from renewable energy resources listed on the Vietnam Stock Exchange.” Although I tried my best to study and research subjects in the Department of Banking and Finance, due to many restrictions in knowledge together with limited time to complete the topic, the graduation thesis was difficult to avoid shortcomings. I hope that Dr.
Luu Thu Quang can contribute more ideas to improve and enhance the graduation thesis. Finally, I want to wish Dr. Luu Thu Quang and the teachers of the Faculty of Banking and Finance more good health and much success in your work. I sincerely thank you!

Share of primary energy and electricity production from renewable resources in Vietnam from 2016 to 2022. INTRODUCTION ABOUT RESEARCH 1. Set research problem At the end of July 2000, there were only two stock symbols listed and traded on the Ho Chi Minh City Stock Exchange Center. The period 2000-2005 was a period of gradual promotion of Vietnam Stock Market when market capitalization during this period only fluctuated around 1% of GDP.
After that, statistics in 2006 showed a strong boom year when the number of listed businesses grew continuously, and under that influence, at the beginning of 2007, Vietnam Stock Market reached a scale of up to 43% of GDP. However, in 2008, the market started to get worse when uncontrolled US subprime mortgage lending activities affected the world. After that, the market gradually recovered slightly in the period between 2009 and 2010 when market capitalization reached 48% of GDP. The period from 2011 to 2016 was a period of outstanding development of the stock market, beginning with a series of state-owned enterprises conducting initial public share auctions.
Then, Vietnam‟s derivatives market was officially put into operation on August 10th, 2017. In 2018, while the Vietnam Stock Market was one of the fastest-growing stock markets in the world, the Vietnam Market became the market with the sharpest decline. In 2019, the Vietnam Stock Market continued to return with positive signs, but in 2020, when the COVID-19 pandemic occurred, the world stock market in general and Vietnam in particular faced an unprecedented decline (Le Hoai An, 2020). After 2020, the COVID-19 pandemic showed signs of drop, and the Vietnam Stock Market still has a positive direction.
Accordingly, the development of renewable energy in the electricity industry has been a new signal and been forecasted to be a promising industry group that will make the stock market more diverse and change for the better. The research problem is that despite playing an important role in the country‟s financial market, the unpredictable fluctuations of the Vietnam Stock Market since its inception have also posed many challenges for investors having difficulty in choosing investment stocks, especially in emerging industries such as renewable 2 energy. In that crisis, forecasting and measuring factors affecting stock prices has become necessary. In the world, there were many quantitative research articles on factors affecting stock prices.
However, with differences in geography, culture, and the characteristics of each country‟s stock market, such studies were difficult to apply in Vietnam.
