1.1 Research background
Vietnam's stock market was launched in 2000, in the first 5 years, the market does not seem to really attract the attention of the wider public and the up and down movements of the market does not create social impact that may extend to affect theoperation of the economy as well as the lives of every citizen.But from the beginning to the mid of 2006, with growth reaching 60%, Vietnam stock market became the 2nd faster frowth “point” in the world anh the awakeing of the fledgling market is increasingly “fascinated” investers at domestic and abroad Many reasons are given to explain this strong growth, but the majority opinions, said that one of the main causes is psychological investing, investing with the movement of investors in domestic “Playing” the stock has been talking as a "fad", a "movement" spread with stunning speed After a time developextremely strongly and considered as one channel with highest interest, end of 2009 stock market peaked at 1,170 points and no brakes sliding bubble stock has burst, many investors were bankrupted… The sharp decline
of the VN-Index was affected by various factors such as tightening of monetary policies, especially lending for stock investment, high deposit interest rates, high inflation rate, and a recession of the US economy Lack of timely intervention of authorities was also areason why VN-Index fell dramatically Many comments and recommendations given by security companies or even global financial organizations did not match with what has really happened Belief in the growth of stock market did not help these analysts to save the VN-Index from remarkable declination After 13-year growth of Ho Chi Minh stock market, Vietnamese investors‟ decisions are still difficult
Trang 81.2 Problem statement
Every theory, every model of efficient markets seems pointless in Vietnam stock market Maybe it's time to use the theory based on basic human psychology to explain stock market anomalies Behavioral finance can be helpful in this case because
it is based on psychology to explain why people buy or sell stocks (Waweru et al., 2008)
Behavioral finance is a financial sector that proposes psychology-based theories
to explain the abnormal stock market In behavioral finance, it is assumed that the information structure and the characteristics of market participants affect system investment decisions as individuals and as a result of market Behavioral finance attempts to explain and increase understanding of the theoretical models of investors,
Trang 9including the emotional processes involved and the extent to which they influence the decision-making process Basically, behavioral finance attempts to explain what, why, and how of finance and investment, from the human perspective There has been controversy about the true meaning and effect of financial behavior since the field itself is still developing and perfecting itself This evolution continues to occur because many scholars have a wide range of such diverse specialties and academic and professional Finally, behavioral finance studies of psychological factors and sociological processes that affect financial decisions of individuals, groups and organizations
Noted by Daniel Kahneman in a speech entitled "Psychology and Market" at Northwestern University in 2000: "If you listen to financial analysts on the radio or on
TV, you quickly learn that the market has a psychology Indeed, it has character It has thoughts, beliefs, moods, and sometimes stormy emotions."
1.3 Scope
There are many psychological factors discovered through research that they have a significant impact on the behavior of investors Among those, there are four common psychological factors exist in almost every human being, there are: Overconfident, ExcessiveOptimism, Psychology of Risk and Herd Behavior
The research was conducted at some securities companies in Ho Chi Minh city and Bien Hoa city,
The goal of this research: prove there is existenceof psychological factors of investorsin Vietnam stock market and clarify the impact of psychological factors to investors‟ target?
This research focuses on understanding and analyzing the impact of the four
Trang 10psychological factors: over-confident, optimistic, attitude toward risk and herd behaviour to individual investors‟ target on Vietnam stock market
1.4Research questions
The research focuses on achieving the following questions:
• What are the behavioral variables influencing investors‟ target? The relationship between these variables
• Are there herd psychological effects on Vietnam stock market?
• At which impact levels (if any) do the behavioral factors influence the individual investors‟ target at the VietNam Stock market?
1.5 Research Structure
This thesis has five chapters
Chapter 1: Introduction, give the overview of the research and the problem need
Trang 11CHAPTER 2: LITERATURE REVIEW AND HYPOTHESES
This chapter presents a review of relevant literature related to factors affecting individual investors‟target This chapter also states the hypotheses and propose conceptual model for this study
2.1 Target of investors
In this study, target of investors was shown through their investment decision making: investors looking for short-term arbitrage or dividend income and capital
gains in the long-term
A long-term investment was defined is holding a stock over one year Theoretically, if you hold a stock for a long time, you will go through periods of volatility and eventually, then you can gain profits as the underlying company grows, with an assumption that a good company will grow increasingly and revenues over time Long-term investment also provides dividend income over the long-term
Short-term investment is not limited to day trading Short-term investment was defined as those that are hold their stock within one year and then take advantage of market volatility that produces a quick profit
Geist (2003) recognized the impact of psychology on investors‟ financial decision making He said that from the investing process however much we try to eliminate our psychology, we will finally fail, because our conscious and unconscious psychological convictions continually operate and influence our decision-making
Trang 122.2 Review of psychological factors and hypotheses
2.2.1Overconfidence
In the financial field, overconfidence is defined as the overestimating valuation
of a financial asset (Odean, 1998)
Investing is not an easy process Investors have to gather information, analyze the information, and making a decision However, investors used to misinterpret the accuracy of our information when they are overconfident and overestimate their skill
in analyzing it It happens after we get some success After getting some success in the market, investors may exhibit overconfident behavior
Many psychological researchers have found that investors used to overestimate their knowledge (Lichtenstein, Fischhoffs and Philips, 1982) and they also overestimate their ability and with the personal importance of the task, their overestimates increase
"People are overconfident Psychologists have determined that overconfidence causes people to overestimate their knowledge, underestimate risks, and exaggerate their ability to control events Does overconfidence occur in investment decision making? Security selection is a difficult task It is precisely this type of task at which people exhibit the greatest overconfidence." (Nofsinger, 2001)
According to Daniel and Titman (1999) overconfidence effects on the way that individual investors process information directly and indirectly The direct effect, discussed by Daniel, Hirshleifer and Subrahmanyam (1998) is that investors put too much weight on their own information because they tend to overestimate the precision
of their information The indirect effect occurs because investors filter information and bias their behavior in ways that allow them to maintain their confidence
Trang 13Barber and Odean (1999) also believe that overconfidence cause high levels of trading in financial markets They attest that overconfidence increases trading activity because it causes investors make sure about their own opinions and not consider sufficiently the other opinions In their paper, they test whether a separate class of investors, those with accounts at discount brokerages, trade excessively, in the case that their trading profits are not enough to cover their costs
In the precision of information, their method to test for overconfident was to determine whether the securities bought by the investors outperformed those they sold
by enough to cover the costs of trading They research return horizons of 4 months, one year and two years following each transaction (they calculated returns from the CRSP daily return files) The results showed that on average, the securities that investors bought underperformed those they sold
Several studies analyze the impact of gender on the confidence level and found that both men and women show overconfidence, but at men the level is higher (Barber and Odean, 2001), but women make the individual investment performance better than men Overconfidence leads to more transactions but hurt the investment performance
H1 Overconfidence has a positive impact on investor‟s target
2.2.2 Excessive Optimism
Althought there are many researchers have extensively studied the effect of overconfident, but the effect of optimism on individual economic choice has little attention Puri and Robinson (2007) is one of the first recorded the impact of optimism
on individuals economic decisions Distinguishing between reasonable and excessive optimism, they document that moderate amount of optimism is associated with better decision making They recorded that reasonably optimistic people work harder It is
Trang 14important to record that optimism is subjective awareness which depends on personality characteristic
In psychology and in finance, optimism took great attention and there has been
a lot of literature on the effect of optimism in decision making Optimism could be defined as the trend to expect the best possible outcome for a certain situation More detail, optimism in literature is defined as the generalized positive expectations about future events (Scheier and Carver (1985))
Optimism is a brainpower attitude that explains situations and events as being best optimized, meaning that in some way for factors that may not be fully comprehended, the present moment is in an optimum state The concept is typically expanded to encompass the attitude of hope for future conditions show as optimal as well This knowledge, although censured by counter views such as pessimism,
idealism and realism, leads peopel believes that everything will be good
A typical theoretical studies performed by Gervais, Heaton, and Odean (2002) found that excessive optimism often cause a positive impact because it encourages managers to conduct investment This effect is positive because the fear of risk causes the negative impact on the value of the company However, excessive optimism also causes a negative impact because it may lead companies or investors accept the opportunity to invest in negative NPV of the asset or the high risk assets
The status of the human psyche tends to rate themselves as superior than average This make them often outrageous optimistic about the market, economic systems and the investment potential Many excessive optimism investors said that bad investments would not have influence with them that could affect the portfolio because people failed to admit workers potentially detrimental in the investment decision
Trang 15The effect of psychological deviations due to excessive optimistic:
- The psychology of optimism might be the main reasons investors are too focused on the company and their investment because of the optimism can bring to them the thought that other companies in the low races with their companies
- The psychology of optimism may be the cause of making the investment trust's net gain from the market, when in fact they are faced with inflation, fees, and taxes
- The psychology of optimism may be the cause for people to invest more rosy reports about the prospects for the company from the analyst or the main listing In addition, those who invested excessively optimistic are generally less important to the bad news about their investments At the same time, optimistic sentiment could cause investors tend to invest in companies in close proximity to their geographic areas (local) because they may be overly optimistic about the local area overview
H2 ExcessiveOptimism has a positive impact on investor‟s target
2.2.3 Psychology of Risk
Since the 1960s, many researchers have used term of perceived risk to explain consumers‟ behavior Within the term of consumer behavior, perceived risk is the risk that a consumer believes it exists in the purchase of goods or services, whether a risk actually exists or not The notion of perceived risk has a strong basis in the term of consumer behavior that is rather similar with the discipline of behavioral finance, that mean between consumers and investors‟ decision making process, there are many similarities
In stock market, investors usually make many uncertain decisions due to
unclear informations, that why investing is really risky The perceived degree of
Trang 16uncertainty by individuals affects their decisions regarding investing, consumption and saving Perceptions include psychological and emotional aspects, which later on
instruct judgment and decision making
Research has shown there is consistency in the public‟s deviations from
objective risk evaluation and that emotional counters appear to drive perceived benefit and perceived risk (Alhakami and Slovic, 1994) They found that if a stock was
„liked‟, people tended to evaluate its riskwas low and its benefits was high and which stock was „disliked‟, the risk was high and benefit was low, which leads to a negative relationship between risk and return
Some studies have shown that attitude to stock market risk depends on the recent behaviour of the stock market (Clarke and Statman 1998; Shefrin 2000;
MacKillop 2003; Grable, Lytton and O'Neill 2004; Yao, Hanna and Lindamood 2004) The other perspective on that evidence can be proceededfrom research by Weber and Milliman (1997) who offered that risk preference may be stable, such as stock market performance, may be engendered by changes in perceptions of risk They further found that influences on investment choices simultaneously affected risk perceptions
When investors are happy, they don‟t like gamble, because they don‟t want to hazard their good mood Thus, we don‟t know exactly how emotional states affect risk preferences and translate into market pricing As with the evidence on the impact of mood on risk choices, experimental evidence concerning the relationship between risk endurance and depression does not provide a clear knowledge Some studies question the significance of perturbation and depression in explaining choices above risky alternatives Others infer that risk aversion is correlated with depressive trend
(Eisenberg, Baron, and Seligman 1998) More importantly, as these authors recognize,
Trang 17risk aversion is correlated with perturbation and depression Eisenberg, Baron,
andSeligman report that the correlation between depressive symptoms and risk
aversion result from the correlation with perturbation
Economic risks can be manifested in lower incomes or higher expenditures than expected The causes can be many, for instance, the hike in the price materials, the lapsing of deadlines for construction of a new operating facility, disruptions in a production process, emergence of a serious competitor on the market, the loss of key personnel, the change of a political regime, or natural disasters
H3 Psychology of Risk has a negative impact on investor’s target
2.2.4 Herd Behavior
Psychology herd or mob mentality describes the way that some people are affected by their close ones through certain behaviors, trends, and / or under the fulcrum The social psychologists study the related topics such as group intelligence, crowd wisdom, and decentralized decision
Psychology herd is mental phenomena of many individuals, arising from the interaction between the psychology of the crowd members or the community, or by certain psychological prominent, influential That is the conscious personality (individual consciousness) disappear and the emotional turning, thinking of the individuals is in the same direction
In the stock market, herd behavior involves the investors tend to ignore the nature of the personal information, incline the observed results (Bikhchandani and Sharma, 2001), incompatible with the basic elements and the foundation of the market
In financial market herding effect is identified as trend of investors‟ behaviors
to follow the others‟ actions Investors usually calculate carefully the present of herd,
Trang 18because investors rely on community information more than private information can conduct the price deviation of the securities from fundamental value; therefore, many good chances for investment at the present can be impacted Researchers also pay attention to herding; because its effect on stock price changes can inpact the attributes
of risk and return models and this has impacts on the viewpoints of asset pricing theories (Tan, Chiang, Mason & Nelling, 2008)
In the area of behavior, herding can engender some emotional biases, including conformity, congruity and cognitive conflict Investors may prefer herding if they believe that herding can help them to extract useful and reliable information In this instance, herding can contribute to the evaluation of professional performance because low-ability ones may mimic the behavior of their high-ability peers in order to develop their professional reputation (Kallinterakis, Munir & Markovic, 2010)
Follow Bikhchandani and Sharma, herd behavior exists in two basic forms of herd behavior is intentional herd behavior and unintentional herd behavior Perspective review on unintentional herd behavior, Christie and Huang (1995) defines that herd behavior is when small investors remove personal beliefs and conduct investment decisions primarily based on those behaviors collective market
H4 Herd Behavior has a positive impact on investor’s target
2.2.5 Moderator variables
The age
The psychologicalevidence shows that older people will react inappropriately with new information because they usually treat and collect new informationsslowly and inefficiently Older investors often have the effect of account allocation weaker
Trang 19(Dhar and Zhu, 2006)and level of confidence lower than the young investor (Barber and Odean, 2001) Research by Kumar (2006) also pointed out that investors were also less implicated in adventure investment activities (take gamble) on the stock market
At the same time, the author also clarified the relationship between age, investment experience and investment skills Research showed that the investment result after 70 years old declined, this demonstrated that the negative effects of age The regression estimates show that investment skills increase with experience due to the positive impact of learning over time but declines with age due to adverse effects of cognitive age At the same time, the decline occurred more rapidly in the older investors have lower levels and poorer
Gender
A number of studies have also clarified the relationship between gender and investment decisions on Vietnam stock market The relationship between gender and psychological confidence, Pulford (1997) concluded malesare more confident than females At the same time, research by Odean (1998) also pointed out that, the overconfident makes investors trade more often than other investors and as a result the transactions are often ineffective
Level
Level of investors help them implement and apply their competencies, talents, help improve the efficiency of investment, investors have a higher level, they aremore optimistic, more confident, less pessimistic and less herd behavior
Investors have low level tend to appreciate the important role of the elements
of macroeconomics in making individual securities investment decisions Beside, there are many factors: recommendations of analysts, market research;
Trang 20recommendations of the stock broker; recommendations from the amateur analysts; insider trading informations; intuition, rumors…also affect investors.The lower level, the impact of these elements stronger,vice versa This affirms, reviewed at a certain aspects, level of investors have a positive impact on the psychology of individual investors

Trang 21CHAPTER 3: METHODOLOGY
This chapter presents the research design process, data collection method and find out relationship between psychological factors and individual investors‟target in VietNam Stock Market
is chosen for some reasons The first reason is that as the research questions are defined clearly, questionnaire is the best choice to have standardized data, which is easily to process, and analyze As the respondents are investors, they may not have
Trang 22much time for interviews, thus, questionnaires may make them feel more comfortable because they can do it whenever they have free time Questionnaires also are more convenient for respondents in case they need to provide some sensitive information, in other words; they tend to be more honest than in an interview (Bryman & Bell, 2007)
3.3 Measurement items
This essay was based on the investigation results analysis by questionnaires to investors, consists 19 questionnaires to identify and measure the behavior of individual investors (Trần Thị Hải Lý & Hoàng Thị Phương Thảo, 2012)
These questions help assess the level of investor confidence:
Investors are confident that they have the ability to choose good stocks than others (c1)
Investors completely control their investment activities (c2)
Investors understand clearly about stocks in their portfolio (c3)
Investors fully understand the market (c4)
Investors have never done an impulsive transaction (c5)
Optimistic sentiment was reflected in the results answer of these questions:
Investors continued to invest in the market (in terms of market going slight increase when the survey was conducted) (o1)
Investors continued to increase capital in the market within the next year (o2)
Over the years, investors believe that the stock market will rehabilitate (o3)
If the VN-Index declined by 5%, the investor believes that the index will quickly recover (o4)
Vietnam stock market is still an attractive investment channel (o5)
Attitudes to risk are reflected in the results answer of these questions:
Trang 23 Investors liked the fluctuate sharply opportunity to receive higher profits (r1)
Investors prefer to invest in companies that are familiar or well-known about it (r2)
When prices fall, investors usually hold stocks longer to wait the prices increase again (r3)
Investors prefer to invest in companies that pay stable dividends (r4)
Herd mentality is shown by the results answer of these questions:
Does an investor consult others decision when investing or not? (ex: petition of broker, analysts…) (h1)
If investors have private information contrary the majority of other investors‟ transactions in the market, do they decide to keep their or not? (h2)
Do investors look at the trading volume on the electrical panel to make the investment decision or not? (h3)
Do investors trade according to foreign investors? (h4)
Investment objectives variable measured by the question:
- Investors looking for short-term arbitrage or dividend income and capital gains in the long term? (Y)
3.4Pilot study
Two phases of study were undertaken in this study: a pilot study and a main survey A pilot study was conducted before formal main survey in order to control errors such as ambiguous or repetitive questions In the pilot study researcher did a pilot survey of 30 people at some security companies The questionnaire was divided into two parts: personal information, behavioral factors influencing investment target
In the part of personal information, nominal measurement was used Nominal scales were used to classify objects: gender, age, educational level
Trang 24In the second part, the questions were designed by 5-point Likert scale (1:
strongly disagree, 2: disagree, 3: neutral, 4: agree, 5: strongly agree)
3.5Main survey
The main survey was distributed directly to investors at some securities companies in Bien Hoa city and Ho Chi Minh city, 400 surveys were given Beside, the author designed the questionnaires on docs.google.com, then posted onsome forums: Phutoan.com.vn, Vietstock.vn, Saga.vn…,The purpose of this survey was to validate the measures and to test the structural model.The detail of the questionnaire in Vietnamese version will be shown in Appendix 1
3.6Methodology of data analysis
3.6.1 Descriptive statistics
To count and evaluate the general information like Mode of data collection, gender, age, education level, of respondents, the descriptive statistics is conducted in this study
3.6.2 Reliability analysis
Thesis will perform verification scales to measure the psychological group through Cronbach's alpha coefficient to optimize the psychological scale Cronbach‟s alpha coefficient was used to test the scales on psychological groups In generally, the value of Cronbach‟s Alpha for acceptable reliability is 0.7, it could decrease to 0.6 in exploration research, and any variables, which have the value of Correlated Item-Total Correlation below 0.4, would consider to be rejected (Hair et al, 1998)
Trang 253.6.3 Exploration factor analysis (EFA)
In this study, EFA method was used mostly for data reductions reason and test validity of measurement scale.Factor analysis can be used to find meaningful patterns within a large amount of data.The goal of factor analysis is to reduce “the dimensionality of the original space and to give an interpretation to the new space, spanned by a reduced number of new dimensions which are supposed to underline the old ones” (Rietveld & Van Hout 1993).By performing EFA, the underlying factor structure is identified For this study, Exploration factor analysis will be conducted by Varimax rotation in condition of KMO value more than 0.5
3.6.4 Binary logistic regression
Binary logistic regression is a type of regression analysis where the dependent variable is a dummy variable (coded 0, 1), in this study, the dependent variable was the target of investors: Investors looking for short-term arbitrage or dividend income and capital gains in the long term? Code 0 is investors choose invest in short-term, code 1
is investors choose invest in long-term
Trang 26CHAPTER 4: RESEARCH RESULTS
This chapter shows the outcome of the questionnaire and analyses of their relevance to objective and the research questions.The data analysis & discussion part were divided into the following sections: descriptive analysis, reliability test, factor analysis, and binary regression analysis
4.1 The main characteristics of the sample
To identify and analyze the behavior of individual investors on Vietnam stock market, thesis author has organized the survey, investigated and interviewed 400 individual investors After checking the answer sheet, 186 votes were not enough reliable information, should not be included in the sample 214 remaining votes were eligible for the sample
