INTRODUCTION

Most of the Indonesian people have carried out investment activities with the aim of having a

decent and sufficient life. However, Indonesian people usually allocate money or income in

several forms, such as consumption, savings and investment. Of these funds, the type of

distribution that is most preferred in the future is the type of investment. According to

(Pritazahara & Sriwidodo, 2015), personal financial management investment planning is vital

for everyone today, because investment is also included in the learning process in studying

current and future finances. Investment can be interpreted as sacrificing a source of income or

funds to buy a stock or product now in the hope of getting a profit in the future. Joko Salim

(2010: 7) states that a person's goals in investing are as follows: first, just in case, second, to get

a profit, third to beat inflation, fourth to have a wrong life in the future, and fifth to prepare a

pension fund.

Based on (Trinugroho & Roy, 2011), there are several investors in the capital market who tend

to show irrational behavior which is influenced by psychological factors that are contrary to

classical theory. Meanwhile, Monowar's (2013) study found that investors in the decision- making process show high or irrational opportunism. In research conducted by (Carolynne L J

Mason & Richard M S Wilson: 2000) regarding financial literacy which only makes a person

able to make decisions based on relevant information. Financial literacy does not guarantee

that the right decisions are made, because a person does not always make decisions based on

economic rationale. Then it can allow an investor to make decisions that are not quite right. An

investor who is prone to biased behavior causes systematic errors and choices of investment

decisions that only satisfy but do not maximize benefits and this event is known as behavioral

finance. When making an investment, it is necessary to make the right decisions where each of

the decisions can affect the investment results. In determining a decision, each individual will

behave rationally and irrationally, depending on the information obtained. Someone with good

financial literacy tends to have better control in determining a diversified investment because

they have a lot of financial information. For example, knowing the range of interest rates and

conditions on the market, understanding how their credit risk profile and personal situation

correspond to interest rates so that they can determine which investment is best for them

(Hilgert et al., 2003).

Basically, investment decisions that are made will affect success in the future, but there are

several factors that influence investment decisions, one of which is Behavioral finance, the

definition of Behavioral finance is a theory that focuses on the psychological influence of

investors in financial decision making and the investor market sometimes makes a decisions

when market conditions are bobbing or floating full of uncertainty. The psychological literature

finds that a person can make mistakes both systematically in thinking such as being too sure of

one's abilities or too dependent on past experiences (Ritter, 2003). Irrational investment

decisions occur under certain conditions of uncertainty and risk. In an uncertain investment

world, investors tend to take overconfidence decisions (Im & Oh, 2016). The content of

behavioral finance consists of Overconfidence, Representativeness, Familiarity bias, and risk

perception.

In general, overconfidence bias is often associated with and equated with optimism, however,

there is a difference between overconfidence bias and optimism bias. For Malmendier (2005),

overconfidence bias is related to the expertise of investors, on the other hand, optimism bias is

related to results originating from aspects outside the system (exogenous). Overconfidence

research on investment decisions carried out by (Bulent & Yilmaz, 2015) generally involves

male investors, young investors, investors with low portfolios and low income investors. For

Lakshmi (2016) Overconfidence is described as a belief that is too much in reasoning,

evaluation and cognitive skills. The concept of Overconfidence comes from a part of

psychological research that creates when people overestimate the expertise and truth of the

data they share. Some investors believe and think their expertise is above the average of other

investors and can complete tasks well and have an unrealistic level of self-assessment

(Pompian, 2006).

Another aspect that affects the attitude of investment decisions is Representativeness.

Representativeness is investment decision making based on stereotype thinking (Shefrin,

2007: 14). A stereotype is an investor's decision-making attitude based on past experiences and

data that match his mental reflection. A person with large Representativeness tends to

overreact when obtaining financial data or other data from colleagues or family who have

invested in the industry. Investors tend to be very vigilant in ensuring investment decisions. In

the research of Ravindra, et.al (2015), it is shown that human representativeness tends to be
