ABSTRACT
In finance, there is widespread agreement that the Capital Asset Pricing Model (CAPM) and
Whitbeck-Kisor Model (WKM) are good predictors of share price movements in stock
markets. While the above assertion had been empirically validated in several stock markets in
developed economies, there have been few such studies in the stock markets of developing
economies like Nigeria. Such studies have now become imperative given the recent
developments that have seen the Nigerian stock market capitalization increasing from N276,
111,743,197.30 on January 2, 1998 to N10, 180,292,984,225.00 on December 31, 2007
without a relative increase in the volume of stocks being traded. To this effect, the major
objective of this study is to examine the relevance of some of the established models that
guide stock price movements in the Nigerian context. For this study, particular reference is
placed on the banking sector, which dominates other sectors in terms of market capitalization
and volume traded in the Nigerian Stock Exchange market. Data for this research were
collected mainly from secondary sources such as audited annual reports of sampled banks,
periodicals, various publications of Central Bank of Nigeria such as annual reports and
statistical bulletins, Daily official lists and statistical year books of Nigerian Stock Exchange,
different publications of Securities and Exchange Commission and Nigerian Deposit
Insurance Corporation. The data set for the study consists of all the 23 pre-consolidation
and 20 out of the 21 post-consolidation bank equity stocks quoted on the Nigerian Stock
Exchange. Spring bank was not included because it has not published any financial
statements after the bank consolidation exercise. The study covered an eight year period
(2000-2007), pre and post bank consolidation periods. Three hypotheses were tested using
the Capital Asset Pricing Model (CAPM) and Whitbeck-Kisor Model (WKM), multiple linear
regression model, and Pearson product moment correlation coefficient. The findings of the
study show that the application of the Capital Asset Pricing Model(CAPM) to Nigerian

dividend payout ratio, and the variability of earnings of the sampled stocks in the Nigerian
Stock Exchange market from 2000-2007.
1. Introduction
1.1 Background of Study
As we know, Research is an organized enquiry or investigation into any subject area of
interest with the aim of providing information for solving identified problem(s). It can be a
revision of accepted theories in the light of new facts or practical application of such new or
revised theories. A research interest can come up from assertions that are subject to validation
or phenomena characterized by controversy and need investigation to find out more.
In the field of finance there are so many such assertions. In finance, there is widespread
agreement that the Capital Asset Pricing Model(CAPM) and Whitbeck-Kisor Model(WKM)
are good predictors of share price movements in stock markets. While the above assertion
had been empirically validated in several stock markets in developed economies, there have
been few such studies in the stock markets of developing economies like Nigeria. Such
studies have now become imperative given the recent developments that have seen the
Nigerian stock market capitalization increasing from over N276billion on January 2, 1998 to
over N10trillion on December 31, 2007 without a relative increase in the volume of stocks
being traded. The fluctuations in stock prices at times do not make economic sense given the
economic reality of the companies. Sometimes stock prices get ahead of what the underlying
business would earn, just as sometimes they fall below. The model(s) that guide this cycle are
quite hazy and there is need to unravel the mystery surrounding the issue of share price
movement.
1.2 Statement of Problem
In Nigerian stock exchange, the appropriate valuation and pricing of securities have remained
problematic. As it were, there seems to be no clear-cut method of fixing share prices in the

Which of the valuation models better explains the price movement of the subject-banks’
stocks in the Nigerian stock exchange?
H1: From the perspective of the Capital Asset Pricing Model(CAPM), the subject-banks
stocks were not correctly valued.
H2: From the perspective of the Whitbeck-Kisor Model(WKM), the subject-banks stocks
were not correctly valued.
H3: None of the valuation models guides the valuation and pricing of ordinary shares of the
subject-banks in the Nigerian stock exchange.
1.6 Scope of Study
Companies quoted on the Nigerian stock market are segregated into many sectors but the area
of interest to the researcher is the banking sector. The decision to research only on banking
stocks is informed by the fact that banks are the major financier of other sectors and hence
banking stock prices should influence the price of stocks in other sectors. The banking sector
also dominates other sectors in terms of market capitalization and volume of equity traded in
the market. Therefore, the findings and conclusions to be derived from this work were as
related to the banking stocks in Nigeria. The study covers the period of eight years (2000-

overall gross domestic product of the nation is bound to increase, as more income will be
generated by the investors. For an investor, it represents a pivotal area around which sensible
investment and financing decisions revolve. The profitability of trading on financial
instruments depends on proper valuation. Therefore when deciding on the investment
structure of an investor, the findings from this study become helpful to the investor. When
deciding on which stock to transact in order to have a justifiable reward valuation is needful.
This work will bring to light and remind potential investors the valuation status of the
Nigerian banking stocks. This knowledge will help them to make informed investment and
financing decisions that can enhance their investment value, which is a sure way to wealth
creation and poverty eradication. Undoubtedly, the study will provide a basis upon which
other researchers in the capital market issues can explore other sectors of the market.
1.8 Limitations of the Study
One major limitation of this study is the unavailability of complete data for 2008 and 2009.
The inclusion of the two years data would have made the work a more recent study and
perhaps would have generated a better result.
2.0 Review of Related Literature
Recall the modern theories underlying the value and market price of securities. Fama(1970)
supported by Patell and Wolfson (1984), Seyhun (1986), Gosnell, Keown and Pinkerton
(1996) are of the view that under efficient market share prices fully and fairly reflect all
relevant available information about the stock. They termed a situation like this efficient
market hypothesis(EMH). Their view was punctured when some anomalies which cannot be
explained within the paradigm of the EMH were detected in the behaviour of stock market
prices as evidenced by a number of research findings such as January effect by Rozett and
Kinney(1976); Weekend or Monday effect by French(1980), Agrawal and Tandon(1994),
Lakonishok and Maberly(1990); Turn of the month effect by Cadsby and Ratner(1992),
Haugen and Lakonishok(1988), Ariel(1987); Pre-Holiday effect by Ariel(1990), Cadsby and
