Recent literatures in empirical finance are surveyed in its relation to underlying behavioral principles, principles which come primarily from psychology, sociology and anthropology. Behavioral finance encompasses research that drops the traditional assumptions of expected utility maximization with rational investors in efficient markets. Herd behavior would be considered one of investors´ behaviors that can affect the stock market efficiency. What is the herd behavior and how it comes into? More researchers think the cognitive bias would result in herd behavior. This article contains three parts. The first part --introduction-we provide a brief introduction of herd behavior; The second part --a case study- (1) A small scale experimental questionnaire investigation, only 99 samples, mainly supplies some cognitive bias evidences in stock market. Through analyzing of questionnaires we can simply certify that the psychogenic characters, social cognition and anthropological characters maybe result in bounded rationality during stock investment. (2) We notice some special information, and their affection would be enlarged by media, and then stock price would fluctuate abnormally. But we discuss, simply, the relationship between the information and stock price fluctuation, without any positive method. The third part: conclusion part. We list the investigation conclusions and explains the possible reasons --conformity pressure, trade-off difficulty and person cognition, incidence of information, neural simulation--why - he endowment effect, sunk cost, house-money effect would effect the person decision and bounded rationality.
