Behavioural finance is of interest because it helps explain why and how markets might be inefficient. For more information on behavioural finance, see Sewell (2001). 2 History Back in 1896, Gustave le Bon wrote The Crowd: A Study of the Popular Mind, one of the greatest and most influential books of social psychology ever written (le Bon 1896). Selden (1912) wrote Psychology of the Stock Market. He based the book ‘upon the belief that the movements of prices on the exchanges are dependent to a very considerable degree on the mental attitude of the investing and trading public’. In 1956 the US psychologist Leon Festinger introduced a new concept in social psychology: the theory of cognitive dissonance (Festinger, Riecken and Schachter 1956). When two simultaneously held cognitions are inconsistent, this will produce a state of cognitive dissonance. Because the experience of dissonance is unpleasant, the person will strive to reduce it by changing their beliefs.

...Management, Vol. 14, No. 1, 2007, 12–29 doi: 10.1111/j.1468-036X.2007.00415.x Behavioural Finance: A Review and Synthesis Avanidhar Subrahmanyam Anderson Graduate School of Management, University of California at Los Angeles, USA E-mail: subra@anderson.ucla.edu Abstract I provide a synthesis of the Behavioural finance literature over the past two decades. I review the literature in three parts, namely, (i) empirical and theoretical analyses of patterns in the cross-section of average stock returns, (ii) studies on trading activity, and (iii) research in corporate finance. Behavioural finance is an exciting new field because it presents a number of normative implications for both individual investors and CEOs. The papers reviewed here allow us to learn more about these specific implications. Keywords: behavioural finance, market efficiency, cross-section of stock returns JEL classifications: G00, G10, G11, G14, G31, G32, G34 1. Introduction The field of finance, until recently, had the following central paradigms: (i) portfolio allocation based on expected return and risk (ii) risk-based asset pricing models such as the CAPM and other similar frameworks, (iii) the pricing of contingent claims, and (iv) the Miller-Modigliani theorem and its augmentation by the theory of agency. These economic ideas were all derived from investor rationality. While these approaches revolutionised the study of finance and brought rigour into the field, many lacunae were left outstanding by...

...THE EVOLUTION OF STOCK MARKET EFFICIENCY OVER TIME: A SURVEY OF THE EMPIRICAL LITERATURE Kian-Ping Lim Universiti Malaysia Sabah and Monash University and Robert Brooks Monash University Background This paper provides an insight into the empirical literature as pertains the evolution of stock market efficiency over time, with a keen focus on the weak form Efficient Market Hypothesis (EMH). The authors provide a systematic review of the correlation between several financial factors namely: Adaptive Markets Hypothesis (AMH), Efficient Markets Hypothesis (EMH), Evolving Return Predictability, Stock markets and Weak-form EMH. The authors pay keen attention on how return predictability from past price changes is affected by key players and determinants on the stock markets. From the survey they conduct, the posit that the bulk of the empirical studies examine whether the stock market under study is or is not weak-form efficient in the absolute sense, assuming that the level of market efficiency remains unchanged throughout the estimation period. The authors acknowledge that one field that has drawn extensive investigation by scholars and other players alike is the predictability of stock returns on the basis of past price changes. This is partly due to its direct implication on weak-form market efficiency. They find that a vast majority of the literature implicitly assumes the level of market efficiency remains unchanged throughout the estimation period. However, the possibility...

...HYPOTHESIS Andrew W. Lo To appear in L. Blume and S. Durlauf, The New Palgrave: A Dictionary of Economics, Second Edition, 2007. New York: Palgrave McMillan. The efficient markets hypothesis (EMH) maintains that market prices fully reflect all available information. Developed independently by Paul A. Samuelson and Eugene F. Fama in the 1960s, this idea has been applied extensively to theoretical models and empirical studies of financial securities prices, generating considerable controversy as well as fundamental insights into the price-discovery process. The most enduring critique comes from psychologists and behavioural economists who argue that the EMH is based on counterfactual assumptions regarding human behaviour, that is, rationality. Recent advances in evolutionary psychology and the cognitive neurosciences may be able to reconcile the EMH with behavioural anomalies. There is an old joke, widely told among economists, about an economist strolling down the street with a companion. They come upon a $100 bill lying on the ground, and as the companion reaches down to pick it up, the economist says, ‘Don’t bother – if it were a genuine $100 bill, someone would have already picked it up’. This humorous example of economic logic gone awry is a fairly accurate rendition of the efficient markets hypothesis (EMH), one of the most hotly contested propositions in all the social sciences. It is disarmingly simple to state, has far-reaching consequences for academic theories and...

...Analysts estimate the value of stocks by calculating their net present value or by folding the future back into the present. In so doing, they are faced with the fundamental challenge identified by Frank Knight, that is, with the difficulty of making decisions that entail a future that is unknown. These decisions, as Knight wrote, are characterized by ‘neither entire ignorance nor complete . . . information, but partial knowledge’ of the world (Knight, [1921] 1971: 199). The finance literature has not examined the Knightian challenge faced by analysts. Indeed, existing treatments circumvent the problem by adopting one of two extreme positions. In the first, put forward by orthodox economists, it is assumed that Knightian uncertainty is non-existent and that calculative decision-making is straightforward. Analysts are presented as mere calculators in a probabilistic world of risk (Cowles, 1933; Lin and McNichols, 1998; Lim, 2001). In the second, put forward by neo-institutional sociologists and behavioural finance scholars, analysts face too much uncertainty to engage in individual calculation. Analysts confront this uncertainty by resorting to a lemming-like imitation of their colleagues’ opinions (see respectively Rao, Greve and Davis, 2001; Scharfstein and...

...are rational. Rational agents is agents which has a clear preferences, models uncertainty via expected values, and always chooses to perform the action that results in the optimal outcome from all the feasible actions. Their actions depend on their preferences, their information of the current situation; which may come from past experiences, the actions, duties and obligations available and the estimated or actual benefits that the agents can get after the actions. In reality, however, agents are not always rational; people’s decision does not always correspond to the concept of economic rationality. Most people, in fact, make their decision rather intuitively. This leads to an interesting new study of behavioural finance, a study that linked psychology with finance. It provides explanations to well-known market anomalies such as: the small firms outperform; in which the case...

...fully describe these words (finance and accounting) as both have very wide meanings and applications in the business world. Most business has an aim to make profit and to remain solvent and the above two concepts play an important role in achieving this objective. This paper aims to answer the above questions and further goes on to say why both should and are considered a vital part of business and their importance in the whole business set up. Literature Review Accounting has been defined as the soul of the business (Collin P, 2004). Accounting is described as the means by which information is communicated in a firm, and is thus known as the language of business. Accounting is described as a vital function in preventing fraud and corporate corruptions in organisations (Glautier, M.W.E. and B. Underdown, Accounting theory and practice). Accounting is important as it provides information to external parties (stakeholders) by providing a true picture on the business financial position. Finance is described as an administrative function aimed at raising funds for the business (B.B Howard. Introduction to Business Finance). Finance is aimed to maximise the value of the firm and attain the main objectives of the firm; I. Shareholders wealth maximisation II. Profit maximisation This is achieved by determining the optimum capital structure and the efficient utilisation of resources by analysing risk and return (B. B Howard. Introduction to Business Finance). Findings and analysis ...

...“When the price of a stock can be influenced by a “herd” on Wall Street with prices set at the margin by the most emotional person, or the greediest person, or the most depressed person, it is hard to argue that the market always prices rationally. In fact, market prices are frequently nonsensical.” ------------------------------------------------- This report will analysis the statement by Warren Buffett, and it considers the contrasting evidence on the validity of the observation on the Efficient Markets Hypothesis. The report briefly outlines the forms of the Efficient Market Hypothesis, the report also analysis’s the evidence both seminal and recent on the theory relating to the three forms of the hypothesis. It also examines the theoretical role and motivation of analysts in creating market efficiency; lastly it looks at alternative perspectives on the pricing of securities. Introduction In 1984 Warren Buffett penned an article titled “The Superinvestors of Graham-and-Doddsville”, based on a speech he had given on the occasion of the 50th anniversary of his mentor Ben Graham’s legendary textbook, Security Analysis. In it, Buffett rejected the then growing (and now entrenched) view in academia that markets are ''efficient'' because ''stock prices reflect everything that is known about a company’s prospects and about the state of the economy.'' Warren Buffett argued against EMH, saying the preponderance of value investors among the world's best money managers rebuts...

...The Australasian Accounting Business & Finance Journal, February 2007 Gaffikin: Accounting Research and Theory: the age of neo-empiricism. Vol. 1, No.1.pp. 1-19. Accounting Research and Theory: The age of neo-empiricism Michael Gaffikin, School of Accounting & Finance, University of Wollongong ABSTRACT The theorising in accounting prior to 1970 was rejected as not providing sufficiently general theories. Informed by theories in economics and finance (and other disciplines such as psychology) and with the aid of computers, attempts to theorise accounting took a new direction. Large data collection and analysis emphasized a purportedly more systematic empirical approach to developing theory. Key words: accounting; neo-empiricism; capital markets research; behavioural finance; efficient markets hypothesis; positive accounting theory INTRODUCTION Around 1970 there was a dramatic change in the approach to accounting research. Several reasons have been suggested for this change in methodological direction by those reviewing the development of accounting thought. To many, a major distinction is a change in direction away from attempts to prescribe a theory of accounting to developing theory from a description of extant practices. To advocates of the latter, previous attempts to develop a theory of accounting were futile as there could never be agreement over many of the inputs into a theory such as the postulates, principles but most specifically the assumptions. Although a...

...THE EFFECTS OF LONG-TERM AUDITOR - CLIENT RELATIONSHIP ON AUDIT QUALITY IN SMEs INTRODUCTION 1.1 BACKGROUND TO THE STUDY Small and medium-sized enterprises (SMEs) play a vital role in the economy of any country, and the impact of their growth is experienced positively across the overall economy. As stated by the European Commission report, Small and Medium-sized Entities (SMEs) represent 99% of all the entities operating in Europe, and have been important for both the social and economic developments in Europe. In Europe, micro-enterprises within the SMEs are considered to be the real giants of European economy, and are the ones with fewer than 10 employees. As per the stats of Eurostat, 67% of the privatesector jobs in Europe are created by SMEs, which represents a major share in the overall economy of a country (European Commission, 2008). Most SMEs encounter limited financial as well as non-financial resources. They depend upon the creditors like banks and other financial institutions, or private equity. In this regard, banks have become one of the major sources for SMEs fulfilling their financial requirements. However, banks are less likely to provide loans without any reasonable assurance of creditability of the firms. Banks generally rely on the financial information of the firms. They do prefer credible audited financial statements by independent auditors as a matter of assurance. In other words, most banks view auditing as a guarantee for the quality of information...

...CHAPTER 9 Behavioural Finance and the Psychology of Investing “The investor’s chief problem, and even his worst enemy, is likely to be himself.” —Benjamin Graham “There are three factors that influence the market: Fear, Greed, and Greed.” —Market folklore Be honest: Do you think of yourself as a better than average driver? If you do, you are not alone. About 80 percent of the people who are asked this question will say yes. Evidently, we tend to overestimate our abilities behind the wheel. Is the same thing true when it comes to making investment decisions? You will probably not be surprised when we say that human beings sometimes make errors in judgment. How these errors, and other aspects of human behaviour, affect investors and asset prices falls under the general heading of “behavioural finance.” In the first part of this chapter, our goal is to acquaint you with some common types of mistakes investors make and their financial implications. As you will see, researchers have identified a wide variety of potentially damaging behaviours. In the second part of the chapter, we describe a trading strategy known as “technical analysis.” Some investors use technical analysis as a tool to try to exploit patterns in prices. These patterns are thought to exist (by advocates of technical analysis) because of predictable behaviour by investors.
