ABSTRACT
Since
the Dutch Tulip Mania of the 1630s, cycles of bubbles and bursts in stock
markets have become commonplace across the world, hence, this has gained a
reasonable academic attention. However answers as to what causes a particular
market crash remains context-specific and in most cases, weakly related to the
overall question of what causes stock market crash and how it can be prevented.
Consequently, the question of what causes a particular market crash remains
context specific which has to be answered for all dips in the stock market.
Recently, Nigeria Capital Market took a plunge downwards in March 2008 after
more than four years of consistent super performance. As is the case in many
other African countries, thus far, explanations are hardly empirics supported.
As a result, specific drivers of the markets given the peculiarities of poor
capitalization, weak underlying economic base and open capital accounts remain
unexamined. This study employs three approaches with two data sources with two data sources – one primary (analyzed using charts and tables as
well as estimates from a censored logit model) and the other secondary
(analyzed using error correction model incorporating macroeconomic indicators)
to examine the relationship between Nigeria Stock market and economic
fundamentals with a view to determining their impact on stock valuation. We
estimated two equations. The first equation showed the relationship of a long
run all share price index with major indicators in the economy and the second
showed a relationship of the actual value of the all share price index with
same set (augmented set) of indicators. The results from the two data sources
significantly corroborated each other. The findings largely indicate disconnect
between economic fundamentals and stock pricing. We explored the implications
on the economy and proffered solutions.
CHAPTER ONE
INTRODUCTION
1.1 Background to the Study
The
occurrence and existence of bubbles have gained reasonable academic attention
(examples include, Froot and Obstfeld, 1992; Allen and Gorton, 1993; Biswanger,
1999; Chen, 1999; Abreu and Brunnermeier, 2003). The existence of stock market
bubbles and crashes dates back to the 1600s. The Dutch tulip mania of 1630’s,
the South Sea bubble of 1719 – 1720 and more recently, the internet bubble,
which peaked in early 2000, are some notorious cases (Abreu and Brunnermeier,
2003). Time and again, both pundits and market makers have had difficulty
correctly foreseeing the direction of the market even in the medium term. For
example, when on March 10, 2000, the technology-heavy NASDAQ composite peaked
at 15, 048.62, very few expected what was to follow the next couple
of months. Even though such high movements were quite contrary to the trends in
the rest of the economy (particularly given that the Federal Reserve had raised
interest rates six times over the same period and that the rest of the economy
was already beginning to slow down), the fall still caught many analysts and
stakeholders unprepared. The bubble burst that followed (generally known as the
dot-com bubble crash) wiped out about 2$5 trillion in market value
of technology companies between March 2000 and October 2002. Many other
(non-technology) stocks followed in the wave of weak confidence in the market
and lost values. A number of reasons have been given for that particular market
crash, but as in many other times, such reasons often relate to market-specific
occurrences and are weakly related to the overall question of what causes stock
market crash and how these can be prevented. Consequently, the question of what
causes a particular market crash remains a context-specific one that must be
answered for all dips in the market.
Investors
sometimes, albeit temporarily, show excessive optimisms and pessimisms which
end in pulling stock prices away from their long term trend levels to extreme
points. Just before a major burst, experience has shown, the market will always
look so promising and attract
some late comers who are also somewhat new and inexperienced in the business.
Unfortunately, they are the most vulnerable in crisis times. However, even for
the more mature investors, there is evidence that following the market is a
very demanding job and hardly does anyone ever do a perfect job of correctly
predicting its direction. In particular, the cause of bubbles remains a
challenge to most analysts, particularly those who are convinced that asset
prices ought not to deviate strongly from intrinsic values. While many
explanations have been suggested, it has been recently shown that bubbles
appear even without uncertainty, speculation, or bounded rationality. For
instance, in their work, Froot and Obstfeld (1992) explained several puzzling
aspects of the behavior of the United States stock prices by the presence of a
specific type of bubble that they termed “intrinsic bubbles”. Bubbles are often
identified only in retrospect, when a sudden drop in prices appears. Such drop
is known as a crash or a bubble
burst. To date, there is no widely accepted theory to explain the
occurrence of bubbles or their bursts. Interestingly, bubbles occur even in
highly predictable experimental markets, where uncertainty is eliminated and
market participants should be able to calculate the intrinsic value of the
assets simply by examining the expected stream of dividends. Clearly, the existence
of stock market bubbles is at odds with the assumptions of Efficient Market
Theory (EMT) which assumes rational investor behaviour. Often, when the
phenomenon appears, pundits try to find a rationale. Literatures show that
sometimes, people will dismiss concerns about overpriced markets by citing a
new economy where the old stock valuation rules may no longer apply. This type
of thinking helps to further propagate the bubble whereby everyone is
investing.
Economic
bubbles are generally considered to have a negative impact on the economy
because they tend to cause misallocation of resources into non-optimal uses. In
addition, while the crashes which usually follow bubbles are momentous
financial events that are fascinating to academics and practitioners, they
often destroy large amount of wealth and cause continuing economic malaise. For
investors, the fear of a crash is a perpetual source of stress, and the onset
of the event itself always ruins the lives of some. Foreign portfolio
investments are withdrawn and/or withheld in order to service domestic
financial problems; prospects of reduced foreign direct investment are bound to
affect investor confidence and the economic health of countries with market
crash. In addition, a general credit crunch from lending institutions for
businesses requiring short-and-long-term money may also result and a protracted
period of risk aversion can simply prolong the downturn in asset price
deflation as was
the case of the 3Great Depression
in the 1930s for much of the world and the 1990s for Japan.
Not
only can the aftermath of a crash devastate the economy of a nation, but its
effects can also reverberate beyond its borders and beyond the time of its
occurrence. Market reversals and the damage they inflict tend to leave
deep-seated memories and emotional scars that are not easily healed with the
passage of time. Clearly, crashes (i.e. bubble burst) occur immediately after
market tops. The problem now arises as to what perennial parameters should be used
to measure the cutting edge of “boom harvest” to avoid unforeseen future market
crash. Osinubi and Amaghionyeodiwe (2002) observed that the securities industry
today is characterized by rapid growth and filled with complexities. New
instruments such as equity options, stock index futures and a host of other
derivatives are being traded throughout the world. The core of all these
activities is the stock market. The stock market, widely described as a
barometer of any nation’s economy, provides the fulcrum for capital market
activities and it is a leading indicator of business direction. An active stock
market may be relied upon to measure changes in the general economic activities
using the stock market index (Obadan, 1998). A robust stock exchange not only
promotes economic growth, but predicts it.
Indeed,
there are several benefits that follow the existence of a robust capital market
in a country. Claessens and Glen (1995) list a number of such benefits, most of
which define it as critical in the development process. For example, the market
remains a veritable source of long term capital for growing businesses,
government social investment among others. A well-managed stock market leads to
diversification of investment and the market provides opportunity to
domesticate wealth. In other words, the Market is a tool for holding back
capital flight. Privatization, regularly used as instrument for increasing the
stake and participation of the private sector in the economy, also cardinally
depends on the stock market. The successful implementation of the divestiture
programs under structural adjustment programmes in many African countries owes
large to the growing importance of the stock market.....
