Classical Finance : The Backbone Of The Financial World

Capital markets provide a function which facilitates the buying and selling of long-term financial securities to increase liquidity and their value, Watson & Head (2013). Hence, the Efficient Market Hypothesis (EMH) explains the relationship that exists with the prices of the capital market securities, where no individual can beat the market by regularly buying securities at a lower price than it should be. This means that in order to be an efficient market prices of securities will have to fairly and fully reflect all available information, Fama (1970). Consequently, Watson & Head (2013) believe that market efficiency refers to the speed and quality of how share price adjusts to new information. Nevertheless, the testing of the efficient markets has led to the recognition of three different forms of efficiency in which explains how information available is used within the market. In this essay, the EMH will be analysed; testing of EMH will show that the model does provide strong evidence to explain share behaviour but also anomalies will be discussed that refutes the EMH. Therefore, a judgment will be made to see which structure explains the efficient market and whether there are some implications with the EMH, as a whole.

The documentary, Mind Over Money, discusses the impact of emotions on financial decisions. Our behavior is bizarre when it comes to money. This video clearly shows this effect in its first example. When a 20-dollar bill was auctioned off, two buyers paid over the bill’s value. People do not use the information they should not be using, but use other information that is said to be crazy to use. The University of Chicago has given rise to the most Nobel prize winners in economics in the world. Here, the theory of economics shows that having rational behavior is one of the most relied on model of economics. Behavior is a very important concept since people are seen to work in their own self-interest.

On the other hand behavioural finance defines the market dynamics and movement in terms of psychology of the participants in the trading process. Behavioural finance proposes that the amount of information available in the market regarding the factors that determine the output or profitability of a particular investment actually serve to determine the movement and output of the market itself (Fama, E.F., 1998).

As Chapter 10 questions, if further evidence continues to surface that capital markets do not always behave in accordance with the efficient market hypothesis, then should we reject the research that has embraced the EMH as a fundamental assumption? In this regard we can return to earlier chapters of this book in which we emphasised that theories are abstractions of reality. Capital markets are made of individuals and as such it would not (or perhaps, should not) be surprising to find that the

Harry Markowitz 1991, developed a theory of “Portfolio choice”, that allows the investors to examine the risk as per the expected returns. In modern World, this theory is known as Modern portfolio theory (MPT). It attempts to attain the best portfolio expected return for a predefined portfolio risk, or to minimise the risk for the predefined expected returns, by a careful choice of assets. Though it’s a widely used theory, still has been challenged widely. The critics question the feasibility of theory as a strategy for

Investment analysis is said to be psychological in various aspects. The irregularity observed in financial markets in recent times has yet again brought to question the practical application of traditional financial theory and the Efficient Market Hypothesis. There is therefore the need to put this base of accepted finance theory under scrutiny. The foundation of one of the broadly examined problems with traditional financial theory is the effect of psychological influences on individuals’ behavior towards investment. According to Slovic (1972), Daniel, Hirshleifer ,Subrahmanyam (1998) and Hilton (2001), they believe that financial markets are functioning at a rapid and increasingly cut throat environment and have been transformed in several ways, one of which is technological. The growing rate of technology has had an immense effect on trading and investment. Technology has aided in allowing information to be easily accessible to investors, but there has been little focus on the issue of interpreting the information skillfully. It is important to note that the appropriate use of information is a crucial part in making investment decisions.

Behavioural economics is the study of the effects that psychology has on the decision making of the economy. This tends to be the way that people think and feel when they are spending money on a certain good or service. The great economist Adam Smith was the first follower of this idea through his book “The theory of moral sentiments” which dates back to 1759. However, it took over 100 years to get a more clarified meaning of how big of a role the psychology of a buyer plays in economics. In behavioural economics there are seven basic principles which all contribute to the decision making process. Behavioural economics can explain how people will react to different situations such as times when there are no economic problems and times when

The perseverance of this final paper is to evaluate the methods in which behavioral finance can be used to elucidate the mortgage crisis and stock market decline. There will be personages’ retorts, specifically investors in the stock market, evidential psychological biases, and a clarification of behavioral finance. In conclusion will be how I can use behavioral finance to overcome some of the psychological biases that ensue.

Keynes (1936, p155-56) describes the stock market using an analogy between professional investment and newspaper beauty contest: “Professional investment may be likened to those newspaper competitions in which the competitors have to pick out the six prettiest faces from a hundred photographs, the prize being awarded to the competitor whose choice most nearly corresponds to the average preferences of the competitors as a whole…It is not a case of choosing those which, to the best of one’s judgment, are really the prettiest, nor even those which average opinion genuinely thinks the prettiest. We have reached the third degree where we devote our intelligence to anticipating what average opinion expects the average opinion to be. And there are some, I believe, who practice the fourth, fifth, and higher degrees.” The Stock Market decisions work based on conventional values too, where each is not concerned with determining the real stock value, but the market value the community will place on the stock, before everyone else does.

The rationalist paradigm (e.g., microeconomics and finance) is focused upon the structure and processes of markets. The market is seen as dominating other potential

Professors George A. Akerlof and Robert J. Shiller are two recognized economists who made numerous pieces of research to emphasize the link between Economics and Psychology. In their book Akerlof and Shiller introduce the concept of “animal spirits” and how the world’s economy is driven by this. According with their view, these “animal spirits” are composed of: confidence, fairness, antisocial behaviour, money illusion and stories. Throughout the book, the authors aim to prove that economists tend to minimize the relevance of the emotional factors and they affirm that a lot of questions about the Finance industry can be answered if people took into consideration that the “animal spirits” had a strong impact on the economy overall.

In his book, Capital Ideas: The Improbable Origins of Modern Wall Street, Peter L. Bernstein examines the innovative financial work of various academics that helped shape modern Wall Street. Bernstein sets out to show that Wall Street is in fact a fundamental and useful model to follow, rather than something to be feared. He points out that, “By combining the linkage between risk and reward with the combative nature of the free market, these academics brought new insights into what Wall Street is all about and devised new methods for investors to manage their capital.” (2) These impressive scholars have incorporated scientific measurement to the art of finance, forever

The efficient market, as one of the pillars of neoclassical finance, asserts that financial markets are efficient on information. The efficient market hypothesis suggests that there is no trading system based on currently available information that could be expected to generate excess risk-adjusted returns consistently as this information is already reflected in current prices. However, EMH has been the most controversial subject of research in the fields of financial economics during the last 40 years. “Behavioural finance, however, is now seriously challenging this premise by arguing that people are clearly not rational” (Ross, (2002)). Behavioral finance uses facts from psychology and other human sciences in order to
