Introduction In this research paper, we examine the distinct theories of traditional and behavioural finance, linking them to efficient market hypothesis. The scope of the paper covers market anomalies as well as behavioural biases of individuals/analysts and the impact of such on portfolio construction. Over the last two (2) decades, behavioural finance has been growing steadily. This growth is associated with the realization that investors rarely behave according to the assumptions made in traditional finance and economics. Traditional finance can be regarded as theories which are currently accepted in academic finance, in which the foundation is based on modern portfolio theory and the efficient market hypothesis. (Baker, 2013)Traditional finance has served to be the dominant paradigm for decades in which investors are guided with regards to decision making. In congruent with the traditional finance theory, the efficient market hypothesis is one of the most accepted theories by academic financial economist. This hypothesis postulates that markets will perform efficiently when there are large numbers of rational profit maximizing investors, who are competing amongst each other in the aim to predict future market values of individual securities. For efficient markets to operate, it is critical for current information to be available at no cost for all investors. The latter was postulated through tests performed by Manderlbort and Samuelson. Furthermore, Fama et al. (The father of modern finance) performed tests to determine whether stock markets are efficient with regards to how quickly they react to new information. The effect of stock splits on prices was studied by Fama et al. and from their observations, it was concluded tha... ... middle of paper ... ...aturdays and Sunday. Under the efficient market hypothesis there should be no difference with regards to the day of the week. Also observed is the holiday effect where there are unusually high stock returns before stock market holidays. A plausible explanation for this is that on a holiday people feel pleasurable which leads to a high purchasing power and as a consequence the high returns for the day before the holiday. With these anomalies that are present within the efficient market hypothesis, the question becomes should we negate the efficient market hypothesis with regards to portfolio construction or should behaviour finance be seen as an alternative to the efficient market hypothesis.

However, there is still a significant degree of uncertainty as to the effectiveness of one strategy over another amongst institutional investors and scholars alike. The vast majority of experienced investors believe that diversification, patience, and value are the three columns of successful investing. On the other hand, many researchers are still in disagreement about how viable other strategies such as growth, short-term and concentrated investing can be. Do all successful investors share this common thread of patience, value, and diversification in their investments or are there a plethora of investing techniques that investors utilize to achieve
Investors on Wall Street remembered October 24, 1929 as the day that the Stock Market plummeted. In just one day, 12,894,650 shares of stock were bought by investors in frantic hopes of stabilizing the market and avoiding bankruptcy. A week later, the New York Stock Exchange suffered another devastating loss, on what has been dubbed ‘Black Monday’. The total number of stock trades had mounted to 16,410,030 shares, setting off a financial panic that would soon sweep the nation (DeGrace). Wall Street, which had once stood as a national beacon of pride, had lost 50 percent of its value by the end of 1929. Although the market experienced a steady decline at the beginning of 1929, there was an expectation that stock prices would continue to boom as they did throughout the 20s (DeGrace). The sharp drop in stock prices came as a shock to most informed
A day after the negative financial news has a greater negative impact on the closing price
The stock market is a volatile, unforgiving battleground where fortunes can be made and lost within minutes. The first major stock exchange in the United States, The New York Stock Exchange (NYSE), dates back to 1792 when it acquired its first securities. Since then, the stock sarket has reached an astronomical size, with a market volume of over twenty trillion dollars. This success is not without its setbacks, though. The stock market crashes of 1929 and 2008 have single-handedly led to the worst economic recessions America has ever seen. Considering the sharp ramifications of a market crash, it is important to understand why
On the night of Monday, October 21st, 1929, margin calls were heavy and Dutch and German calls came in from overseas to sell overnight for the Tuesday morning opening. (1929…) On Tuesday morning, out-of-town banks and corporations sent in $150 million of call loans, and Wall Street was in a panic before the New York Stock Exchange opened. (1929…)
John Locke, a physiologist from the 1700s stated that children are born as a “blank slate” and are continually shaped by their experiences. The principles behind behaviourism explain, in this case, the conditioning of a child and how this is achieved. This is done so without regards to thoughts or feelings, and that psychological disorders are best treated by altering behaviour patters (Q. Faryadi 2007). Behaviourism is a key area in the teaching of children and allows for the conditioning of children. However, by around 1930, Watson’s behaviourism begun to arise doubts in the scholars of the time and many psychologists questioned if this was the correct method of controlling children. (J. Moore 2011). Modern, contemporary classrooms must be “up to date” and technologically advanced, however, it is the underlying importance of teaching methodology that is key. In this essay, the idea of the focus on the behaviouristic methods are assed as well as how it should be integrated into the modern day classroom.
A generation ago, it was generally believed that security markets were efficient in adjusting information about individual stocks and stock market as a whole (Malkiel, (2003)). However, we cannot deny the efficient market hypothesis has several paradoxes.
According to Perold (2004), ‘CAPM can be served as a benchmark for understanding the capital market phenomena that cause asset prices and investor behavior to deviate from the prescript...
The project is done to find out the impact of stock split on the stock market. In our project, we have made use of event study methodology to assess the accuracy of stock price reaction of 39 public listed Indian companies in National Stock Exchange (BSE) in the year 2006 and onwards. The abnormal returns (actual returns-returns from regression line) results were taken for 20 days before and after the announcement date to test whether the result is significant or not (Level of significance=5%). The project shows that there is no significance difference in the price level before the announcement date while after the announcement date, there was a significant difference in the price level for few days(level of significance being 5%) The project supports the hypothesis that Indian stock market is semi strong efficient.
Chapter 11 closes our discussion with several insights into the efficient market theory. There have been many attempts to discredit the random walk theory, but none of the theories hold against empirical evidence. Any pattern that is noticed by investors will disappear as investors try to exploit it and the valuation methods of growth rate are far too difficult to predict. As we said before the random walk concludes that no patterns exist in the market, pricing is accurate and all information available is already incorporated into the stock price. Therefore the market is efficient. Even if errors do occur in short-run pricing, they will correct themselves in the long run. The random walk suggest that short-term prices cannot be predicted and to buy stocks for the long run. Malkiel concludes the best way to consistently be profitable is to buy and hold a broad based market index fund. As the market rises so will the investors returns since historically the market continues to rise as a whole.
There is a lot of research work going on in this particular field, more so since the crisis of 2008. The purpose of this article was to make readers aware of the subject .Behavioral finance is an interesting mix of logics, psychology and economics. Budding investors and management students should look into this in more detail so that they are better equipped to make financial decisions.
The efficient market hypothesis has been one of the main topics of academic finance research. The efficient market hypotheses also know as the joint hypothesis problem, asserts that financial markets lack solid hard information in making decisions. Efficient market hypothesis claims it is impossible to beat the market because stock market efficiency causes existing share prices to always incorporate and reflect all relevant information . According to efficient market hypothesis stocks always trade at their fair value on stock exchanges, making it impossible for investors to either purchase undervalued stocks or sell stocks for inflated prices. As such, it should be impossible to outperform the overall market through expert stock selection or market timing, and that the only way an investor can possibly obtain higher returns is by purchasing riskier investments . In reality once cannot always achieve returns in excess of average market return on a risk-adjusted basis. They have been numerous arguments against the efficient market hypothesis. Some researches point out the fact financial theories are subjective, in other words they are ideas that try to explain how markets work and behave.
Since the originative works of Fama (1965 and 1970), where an efficient market from the informational execution point of view was defined as one where “stock prices ‘fully reflect’ all available information” (Fama 1970) and market efficiency was categorized into three levels: weak-form, semi-strong form and strong-form. First of all, the information set through weak form efficiency, reflects only the historical prices or returns. Second of all, the information set in semi-strong form efficiency, contains information available to all market participants. Lastly, in strong form efficiency, the information set consists of all information available to any market participant.
This paper will define and discuss five financial theories and how they impact business decisions made by financial managers. The theories will be the Modern Portfolio Theory, Tobin Separation Theorem, Equilibrium Theory, Arbitrage Pricing Theory (APT), and the Efficient Markets Hypothesis.
In the modern world, financial markets play a significant role, with huge volumes of everyday dealings. They form part of contemporary economic lifestyle and determine the level of success of many people. Humans have always been uncertain of what the future holds and thus, tried to forecast it. The forecast of course cannot omit the likelihood of “easy money” by forecasting the prices of equity markets in the future.
