In the financial markets, we often observe some phenomena which cannot be explained rationally. For example, we do not have any logical evidences on random walk in the post price movement while many fund managers use several behavioral concepts in their investment strategy. In corporate perspectives, company owners and managers do not rely only on logical elements to trade name critical decisions on mergers and acquisitions and new investment.Two of the key topics discussed in behavioral finance ar e the behavioral finance macro, which recognizes anomalies in the EMH that behavioral models can explain, and the behavioral finance micro, which recognizes individual investor behavior, or biases that are not explained by the traditionalistic models incorporating rational behavior. In particular, we go for the behavioral finance micro because it explains a number of all-important(a) support and investment patterns by using a behavioral approach, which expands on the research in the behavioral corporate finance field. This paper summarizes these two major topics in behavioral finance, which include behavioral corporate finance, and introduces evidence that adopts behavioral concepts in the echt financial market. It excessively describes challenges to behavioral finance by reviewing recent studies and surveys.Recently acknowledged theories in academic finance are called standard or traditional finance theories. Based on the standard finance paradigm, scholars have sought to und erstand financial markets using models that presume that investors are rational. MPT and the EMH form the basis of traditional finance models1). How1) Harry Markowitz introduced MPT in 1952,and he illustrated relationships between portfolio choices and beliefs in terms of the expected returnsvariance of returns rule. Ricciardi and Simon (2000) defined MPT as an expected return, while standard deviations of particular securities or portfolios are correlated with the other securities or mutual funds held within one portfolio. Another major concept is known as the EMH, which states that investors cannot consistentlyever, if researchers only use the MPT and EMH, individual investor behavior is not easily understood.In contrast, behavioral finance is a relatively new concept in the financial markets, and is not employed within standard finance models it replaces traditional finance models, and it offers a better model for homophile behavior. Although MPT and the EMH are considered as su ccessful in financial market analysis, the behavioral finance model has been developed as one of the alternative theories for standard finance. Behavioral finance examines the impact of psychology on market participants behavior and the resulting outcomes in markets, focusing on how individual investors make decisions in particular, how they interpret and act on specific information. Investors do not ceaselessly have rational and predictable reactions when examined through the lens of quantitative models, which means that investors decision-making processes also include cognitive biases and affective (emotional) aspects. The behavioral finance model emphasizes investor behavior, lead-in to various market anomalies and inefficiencies.This new concept for finance explains individual behavior and group behavior by integrating the fields of sociology, psychology, and other behavioral sciences. It also predicts financial markets. Research in behavioral corporate finance studies highlig hts investors and managers irrationality, and shows nonstandard preferences, and judgmental biases in managerial decisions. Currently, many companies apply behavioral approaches to determine important finance and investment patterns. Several theories under the banner of traditional finance develop specific models by assuming the EMH and they explainphenomena in markets however, in the factual financial market, many problems and cases cannot easily be explained via those standardizedmodels.In the cases involving managers or investors, unbiased forecasts about future events need to be developed and used to make decisions that best serve their own interests. In this type of situation, we need to entertain more realistic behavioral aspects, as there is evidence for irrational behavior patterns that cannot be explained by the traditional or standard financial theories. To be specific, Shefrin (2009) pointed out that the root cause of the globalachieve an excessive return over market re turns on a risk-adjusted basis because all publicly available information is already reflected in a securitys market price, and the trustworthy security price is its fair value.Financial crisis of 2008 was a psychological, not fundamental phenomenon. Risk-seeking behaviors were evident in the loss-dominant markets, while excessive optimism and confirmation bias acted as drive factors behind the crisis, and not fundamental factors such as terrorism, skyrocketing oil prices, or disruptive changes in the weather. We can understand, identify, and address psychological distortions in judgments and decisions by considering behavioral concepts, and then we can integrate both traditional and behavioral factors to be better prepared for dealing with any psychological challenges. As mentioned, managerial decisions are strongly affected by cognitive biases and emotional aspects in real financial markets, as human beings are not machines. Additionally, evidence ofmispricing and market anomali es that cannot be fully explained by traditional models, is prevalent.Thus, we would like to propose behavioral finance in this paper to clearly explain a number of important financing and investment patterns, aidinginvestors in understanding several abnormal phenomena by integrating behavioral concepts with existing.Ricciardi and Simon (2000) defined behavioral finance in the following manner Behavioral finance attempts to explain and increase understanding of the reasoning patterns of investors, including the emotional processes involved and the degree to which they influence the decision-making process. Essentially, behavioral finance attempts to explain the what, why, and how of finance and investment, from a human perspective (Page 2) (See figure 1). Shefrin (2000), however, mentioned the difference between cognitive and affective (emotional) factors cognitive aspects concern the expressive style people organize their information, while the emotional aspects deal with the way people feel as they register information (Page 29).We understand that there are several survey literatures on behavioral finance. However, this paper differs from the literature in several aspects. We introduce more recent papers in the field and expand the research scope to studies on Korean financial markets. We introduce more literature on behavioral corporate finance, provide statistics on the recent trends that are evident in behavioral finance papers, introduce the specific funds that are using behavioral finance techniques, and discuss the challenges of the behavioral finance model.Source Ricciardi and Simon (2000)particularly regarding market anomalies and investor behavior, which cannotbe explained by traditional finance paradigms. In section 2, we introduce two topics in behavioral finance cognitive biases and the limits of arbitrage. In section 3, we summarize the research on behavioral corporate finance. In section 4, we examine behavioral applications via two routes evi dence from real investments and specific evidence from the Korean financial market. In section 5, we analyze the recent developments in behavioral finance publications. Section 6 discusses several challenges to behavioral finance and ends with suggestions for future research.TWO TOPICS IN BEHAVIORAL FINANCEBehavioral finance is a study that combines psychology andeconomics, and it tries to explain various events that take place in financial markets. For example, from the behavioral financeperspective, some individuals limitations and problems are shown in the expected utility-grade theory and in arbitrage assumptions. In particular, there are two representative topics in behavioral finance cognitive psychology and the limits of arbitrage.2)Cognitive Biases downstairs the traditional and standard financial theories, investors are viewed as being rational. Basically, a rational economic person is an individual who tries to achieve discretely specified goals in the more or less compr ehensive and consistent way while minimizing any economic costs. A rational economic persons choices are determined by his or her utility function.
