What Contribution Can Behavioural Finance Make to the Explanation of Stock Market Bubbles and Crashes?

It is believed that Efficient Market Theory is based upon some fallacies and it does not provide strong grounds of whatever that it proposes. More importantly the Efficient Market theory is perceived to be too subjective in its definition and details and because of this it is close to impossible to accommodate this theory into a meaningful and explicit financial model that can actually assist investors in making the investment decisions (Andresso-O’Callaghan, B., 2007).

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

As an investor one needs to be immune to the emotions of greed and fear. In a bull market people fall victim to greed. They are afraid that if they don't sell

The stock Market crash was caused because the market was overrated, overbought and dominated. The economic conditions were not helping anyone. The Crash was due to the market opening of 11% or less. Financiers and institutions chipped in with proposals over the market price to stop the panic. Even though the losses on that day were smaller compared to the next two days. Yet, this loss was unreal, as the next Monday, commonly now known as Black Monday the losses were dropping 13% without provoking the margin calls. Afterward, the offers disappeared completely and the market fell again, another 12%. From this point on the market completely fell hitting rock bottom causing horrible things to go wrong. This was one of the factors that lead to the great depression.

Financial Assets: Robert Shiller, a Noble Prize winner in Economics, has the belief that our cultural and psychological thoughts influence our financial behavior. Shiller highlights the key factors of the irrational exuberance that exists in the financial market. In his book, Irrational Exuberance, he argues that investors often make irrational decisions. Throughout the book, he explains that there are twelve factors that impact the market behavior from 1995 to 2005 and that eventually led to a financial bubble. Some of these factors can be linked to the Black Thursday of 1929.

The irrational behavior in the stock market also precipitated the depression. There were cases in the late 1920s of ordinary citizens becoming very wealthy by purchasing stock. Some of these people were engaged in speculation, meaning

It is often said that perception outweighs reality and that is often the view of the stock market. News that a certain stock may be on the rise can set off a buying spree, while a tip that one may be on decline might entice people to sell. The fact that no one really knows what is going to happen one way or the other is inconsequential. John Kenneth Galbraith uses the concept of speculation as a major theme in his book The Great Crash 1929. Galbraith’s portrayal of the market before the crash focuses largely on massive speculation of overvalued stocks which were inevitably going to topple and take the wealth of the shareholders down with it. After all, the prices could not continue to go up forever. Widespread speculation was no doubt a

Miller is an adherent of fundamental analysis, an approach to equity investing he had gleaned from a number of sources. Miller’s approach was research-intensive and highly concentrated. Nearly 50% of Value Trust’s assets were invested in just 10 large-capitalization companies. While most of Miller’s investments were value stocks, he was not averse to taking large positions in the stocks of growth companies. Overall, Miller’s style was eclectic and difficult to distill.

Further to the argument that agents were ignorant of and failed to engage with new information, the formation of asset price bubbles has been offered as a cause for the GFC. Ball argues that it is inherently difficult to recognise the presence of an asset price bubble until after the event has affected the market and even by recognising that prices did not accurately reflect true value, this could never have indicated a nearing price bubble burst to investors because EMH suggested that all then available information was

Throughout the text of the book, you will read about different bubbles that occurred in history. Some of these bubbles have happened in the last ten years and some have happened in the last three hundred years. One of the most interesting bubbles that I read about was “The South Sea Bubble”. The South Sea Company in England was formed in 1711 to create confidence in the government’s ability to meet its debts and promises. This company took a government debt (IOU) for ten million pounds. In return, the government was given monopoly over all trade to the South Seas (Malkiel, Page 41). People thought there would be a lot of opportunity to make money during this time. In 1720, the entire national debt, which was thirty one million pounds, was capitalized. The stock rose from 130 pounds to 300 pounds when the bill was introduced to Parliament. After bill became the law, the South Sea Company sold a new issue of stock at 300 pounds. There were fights that broke out by investors who wanted to purchase this new stock price at a proposed installment offer.

investors are rational and risk averse, meaning they will always value securities with higher returns than securities with lower returns.

In regards to investing in stocks, bonds, currencies, or other investment products, it has always been a normal emotion to be happy when a stock price rose and upset when a stock price fell. Yet for Warren Buffet and his team at Berkshire they welcome these declining prices because of the opportunities it brings. According to Warren Buffet, a true investor would be buying stocks and businesses for their entire life, and “with these intentions, declining prices for businesses benefit us, and rising prices hurt us.” Understanding that the investor is going to be a buyer for eternity an investor should

Now that the two theories have been explained, let’s look at some historical examples from Malkiel that really paint the picture in chapter 2. The first speculative craze noted was over tulips in the seventeenth century in Holland. The tulips were brought from Turkey and the Dutch valued the beauty and rarity of the new flowers. Thus the prices for the flowers inflated. As the prices rose merchants would by stockpiles to sell to the public. The more expensive they got the more the public believed they were making smart investments. People would sell off the personal belongings to get their hands on the bulbs. The mania surrounding the bulbs created a bubble that would soon burst. The prices got so high some people decided to cash in and sell them to make a handsome profit. Soon others joined in causing a snowball effect and the prices tumbled. Eventually there was no demand and they were worthless. Many went

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

Gittman (2004, pp. 312) divided stock into two types, such as common stock and preferred stock. He also showed that dividends are the outcome of investment. So, common stocks are an ownership claim against primarily real or productive asset (Higgins, 1995), but he also said that if the company prospers, stockholders are the chief beneficiaries, if it falters, they are the chief losers. Smith (1988) presented that stocks are one of the most popular forms of investment. People buy stocks for various reasons: some are interested in the long-term growth of their investment by buying low priced stock of a new company in the hope of substantially growth of share price over the next few years. Another reason he suggested that in a well established firm stockholders expect the stock growth will be stable over the long run. (Smith,1988).
