A survey of behavioral finance
By trying to establish rumors' credibility, people attempt to anticipate changes that are likely to occur in the financial market. This is possible when rationalization is taken as a limit to arbitrage. The way of spending variates from person to person is the phenomena might also explain the concept of January Effect anomaly, which is not related to the taxes as the model was tested in different countries, and the tax year of each country is different. Behavioral finance has basically emerged from the theories of psychology, sociology and anthropology the implications of these theories appear to be significant for the efficient market hypothesis, that is based on the positive notion that people behave rationally, maximize their utility and are able to prices observation, a number of anomalies irregularities have appeared, which in turn suggest that in the efficient market the principle of rational behavior is not always correct. The vast majority of money managers are categorized as either value managers or growth managers although a third category, market neutral managers, is gaining popularity these days and may soon rival the so-called strategies of value and growth. This essay also discusses about two main topics; limits to arbitrage and psychology. We discuss these two topics, and then present a number of behavioral finance applications: to the aggregate stock market, to the cross-section of average returns, to individual trading behavior, and to corporate finance.
Researches show that stock returns are typically unpredictable based on past returns where as future returns are predictable to some extent. According to the traditional view of Investment management, fundamental forces drive markets, however many other investment firms considers to be active and working out based on their experienced Judgment. Human behavior involves a tendency of free flow of ideas and thoughts exchange known as conversation, to exchange a wide variety of information: with the evolution of time, modern civilizations have come up with other structured environment for exchange of information e. The ownership society seems very attractive when people appear to make profits from their investments. It has been found that quite a few people foresee behavioral finance displacing the age old Efficient Markets theory.
In this part Barberis and Thaler summarize the psychology and summarize what psychologists have learned about how people appear to form beliefs in practice. References: Brav, Alon, Heaton, B. Regardless of the fact that their decision would change based on the information. Explaining the irrational effort to interpret the conflicting evidence. Secondly through the process of evolution, irrational decisions will eventually be eliminated in the long run. Market grades you on a daily basis. Whereas to analyze this risk taking behavior we further divided into two main factors: a Loss aversion Being more sensitive to losses than gains, while loss aversion only considers the investment behavior regarding losses, the disposition effect will take care of profits Results confirm the hypothesis that Herding Managers are More loss averse.
It has been proved in the past that people often make the errors that are represented by the cognitive dissonance theory. If we focus on the latter, we are able to see behavioral finance literature that highlights the superiority of such strategies in the ability of analysts to extrapolate results for investors. It is perhaps the most prominent bias on human information processing. Trading in the same direction of noisy traders and arbitrageurs can also caused problems. Framing is basically the problem of decision making where the decision is based on the point where there is difference in how the case is presented to the decision maker. Positively framed participants seemed to be more optimistic about the likely performance and profit of their assets.
These are discussed the rules of a polite conversation, which calls for the respect for common consensus on the topic of discussion. I would like to thank Ken Froot and Andrei Shleifer for sharing their data and ideas, and Rongbing Huang for research assistance. Representativeness leads to - base rate neglect: putting too much weight on the p description statement and too little weight on the base rate p statement. Sandroni further investigates that who will actually survive when the Bayesian and Non Bayesian agents learn to forecast correctly, and presents evidence that Bayesian agent will drive Non Bayesian agents out of the Market. Their task is to act as specialized investors on other peoples behalf.

However observing the day-to-day market behavior one would find that not all players act in this way and an observation of a longer period of asset price fluctuation makes one believe that there are rare people who act mathematically correct or rational with respect to classical utilitarian definition. The study fails to prove that investors systematically over extrapolate a consistent sequence of financial performance at long horizons; to some extent it is proved that investors under react to a one year trend in accounting performance. People when decide on the basis of the rules of thumb regardless of rationalizing suffer from Heuristics. We discuss these two topics, and then present a number of behavioral finance applications: to the aggregate stock market, to the cross-section of average returns, to individual trading behavior, and to corporate finance. Every member should be given a chance to communicate. Though it is not always possible to differentiate between overconfidence in one's own knowledge or overconfidence in one's own abilities. To many researchers the study of behavior in finance appeared to be a revolution.
So, the idea of analyzing other model of human behavior has came up. These assumptions have been challenged. Although future is unpredictable, we can not think a long term policy founded on such few can survive dispassionate analysis of the probability of a crash and the cost of guarding against one long. Behavioral Finance and Rational debate: The article by Heaton and Rosenberg,2004 highlights the debate between the rational and behavioral model over testability and predictive success. They may have very rational and logical expectations at some level for the likely outcome of their gamble. The survey done by Lutje, 2004 concludes that herding is induced by career concerns, as asset managers working effort is not monitored by the client and just by his supervisors; he has some opportunity to reduce his working hours. And we find that neither of them actually offers either of these measures of success.

People get psychological satisfaction when they realize themselves to be better than the rest and are uncomfortable when they know that the care is vice- versa Self is illusory. It is perceived to a large extent by a great majority of asset managers. There are two types of overconfidence: Overconfidence in one's own knowledge, Overconfidence in one's own ability. Aversion to regret leads to a preference for stocks of good companies. Differences across groups in such dimensions. Investors suffering from Representative bias initially overreact but again reconcile with the observations that confirm their bias or correct for the past overreaction when faced with disconfirming observations.

Because there are some risks and costs. In order to better understand the situation we must compare the two scenarios where One agents process information according to the Bayes rule Bayesian Paradigm and Second, agents who use behavioral rules to update beliefs Non-Bayesian Behavioral Models. Similarly these strategies may also limit arbitrage against mispricing, through the great risk associated with stocks. The field of psychology has its roots in empirical observation, controlled experimentation, and clinical applications. Bad news about this fundamental value causes the stock to fall even further.
Other researchers have also criticized the idea that the behavioral finance models tend to replace the traditional models of market functions. Take for instance the concept of mispricing when there is no arbitrage. Since objectively irrelevant information influenced market behavior, our findings violate expected utility theory and the invariance axiom. Hind sight: Hindshight bias leads people to exaggerate the quality of their foresight. Both the rational and behavioral approaches to finance have made progress in understanding the three puzzles singled out at the start of this section.
