| dc.description.abstract | A significant portion of the theories in economics arid finance are based on the assumption that markets are efficient and that individuals are rationalizing the current knowledge when investing. However, in daily life, the decision-making position of individuals exhibited irrational behavior and repeated trial errors have been revealed by many experimental studies. In particular, the adequacy of traditional theories has become debatable in explaining,, fin.a:ncil events since the 1980s. As a result of the studies of Kahneman and Tversky .(1979), behavioral finance, which entered into the literature, investigated the causes, effects and consequences of these irrational behaviors of individuals on investment decisions. In the first part of the study, traditional theorie and Kahneman Tversky's expectation theory were mentioned. In the second part;_ many ;fovestor tendencies such as overconfidence, optimism, uncertainty avoidance, avoidance of repentance, heuristics, cognitive dissonance, overreaction and low; reaction are explained in detail. In the last section, a survey was carried out to , determine whether the overreaction hypothesis, which has been validated in different countries, is valid in the stock market in 2010-2018. As a result of the study using De Bondt and Thaler (1985) method, it supports the excessive reaction hypothesis and statistically significant results were obtained. | en_US |
