ABSTRACT
In view of the significance and potential of the stock market toprovide the required capital for agro-based companies, a timeseries analysis of the performance of selected agricultural basedcompanies in the Nigerian Stock Exchange (NSE) was carried out.Monthly records of Volume of shares traded (VOL) as well as itsdeterminants such as Current Market Price (CMP), Dividend (DIV),Earnings Per Share (EPS), Price Earning Ratio (PER), EarningYield (EARN), and Dividend Yield (YIELD) were obtained from theNSE as an indicator of performance within a time frame of 10years (1998 – 2008). Due to the non-stationarity of the variablesunder consideration, the economic model was re–conceptualized asa Vector Auto – Regressive (VAR) system allowing for thepossibility of co– integration among the endogenous variables.Having established that more than one co–integrating vectorexisted in the data through the Johansen test, we estimated therestricted VAR using the Vector Error Correction Model (VECM)imposing normalization of VOL and PER. The result of the analysisrevealed that VOL is positively related to YIELD and CMP while itis inversely related to EARN, EPS and DIV. On the other hand PERincreases with increasing EPS and DIV but reduces with increasein EARN and CMP. Short run adjustment coefficients were generallylarge ranging from 4 months to 10 years. However, variablescoefficients were more elastic in the long run. Hence, a longterm investment in agriculture was recommended. Investors wereequally advised to play more to rules to raise their price

earnings ratio which has been identified as a veritable tool instock analysis.
KEY WORDS: Performance, Agro-based, Stock Exchange, Nigeria
Introduction
Arising from the nation’s practical experience in the
process of economic development and industrialization, it is now
being increasingly appreciated that agriculture constitutes the
solid and sound base upon which Nigeria’s stable, sound and
realistic economic superstructure could be erected and that its
pace of development will determine, to a very large extent, the
pace of the nation’s economic progress in the near and distant
future. Nigerian agriculture has, for too long, been starved with
the needed capital. For as long as the supply of capital to rural
activities remain scanty, talks concerning agricultural
improvement, the supply food and raw materials will continue to
be academic. The role of the agricultural sector in contributing
to economic development depends not only in creating a conducive
financial environment for the farming community alone, such
attempts must be extended to develop conditions that will enhance
the growth of the agro industrial sector which takes on the
excess that is not immediately consumed. The growth of these
industries depend to a large extent on access to finance which
can be gotten from a variety of sources, but to a large extent
from the equity shares sold on the stock exchange. The activities
2
of stock market are therefore of interest to both the consumers
and producers in planning their decisions. The performance of the
Nigerian Stock Exchange is regarded as an important indicator of
the ability of the economy to withstand shocks in monetary and
fiscal terms. This study thus attempts to give a picture of the
price, quantity and value movements of shares in selected
agricultural based companies in order to determine their
performance in the economy. In addition, Short run and Long
elasticities of performance (volume of shares traded) in response
to changes in key macroeconomic variables were duly investigated.
Theoretical and Methodological Framework
The usual approach to determining performance had been the
construction of econometric behavioural models involving relevant
variables, and the commonest approach to such models estimation
involved applications of the classical least square technique or
some variant of this to the level of the series (Greene, 1997). A
major presumption with econometric time series analysis by least
square regression is that the series are stationary: meaning that
they maintain constant means, variances and auto covariances over
time. The problem however, has been observed overtime that most
economic time series are not stationary. Furthermore, Granger and
Newbold (1974) had earlier reported that application of least
square regression to equations containing non-stationary series
results in spurious regression. They emphasised further that
3
while coefficient estimates from such model may appear to be of
correct signs and magnitudes, deeper investigations often reveal
flaws. The import of this is that standard inference procedures
do not apply to regression models that contain non-stationary
series. (Granger and Newbold, 1974)
The search for appropriate techniques for modeling economic
relations involving non-stationary series led to the emergence of
Error Correction Modeling (ECM) techniques of Engle and Granger
(1987), which permits incorporation of both the long-run and
short-run dynamics of a group of non-stationary series into
econometric models. For example, application of ECM would allow
estimation of both the short-run and long-run elasticities of
trade response, and the speed with which volume of shares traded
for example would return to its long-run equilibrium after short-
run disturbances. A major requirement for ECM, however, is the
test for cointegration, which seeks to verify whether or not a
linear combination of the non-stationary series is stationary,
and can thus describe long run or equilibrium relationships
(Engle and Granger, 1987). The problem however, has been that
multiple co-integrating relations often emerge in tests for
cointegration. This brings the identification problems of
simultaneous equation modeling into ECM such that the estimates
may not be unique nor be directly interpretable, unless some
identifying restrictions are imposed. This problem has however
been solved by more recent methodologies in co-integration and
4
ECM developed notably by Johansen (1991, 1995a,b), Johansen and
Juselius (1990, 1992, 1994), Hansen (2002), and we have what is
now known as Vector Error Correction Modeling (VECM). While co-
integration and vector error correction modeling (VECM) have
become the standard techniques for modeling economic relations
involving non-stationary time series (Hansen, 2002), only very
few applications have been undertaken in Nigeria. Thus, this
study applied the technique of co-integration and VECM in
analyzing the performance of shares of agricultural based
companies in the Nigerian Stock Exchange between 1998 and 2008.
Research Methodology
Scope and Data
The focus of this study is on three selected agricultural
based companies quoted in the Nigerian Stock Exchange (NSE). The
companies include Okomu Oil Palm PLC., Livestock Feeds PLC. and
Nestle Nigeria PLC. Okomu Oil Palm PLC was listed on the Nigerian
Stock Exchange on March 3, 1991, Livestock Feeds PLC was listed
in December 1978, while Nestle Nigeria PLC was listed on April
20, 1979. Data which was strictly time series were collected from
the NSE for a period of ten years from 1998-2008 on a monthly
basis. This resulted in a 396 data set for analysis. The data
were collected from the records of the daily official listings of
companies quoted in the NSE, information on Volume of share
traded, public quotation price, the current market price, the
5
earnings per share, price–earning ratio, and distributed
dividends of the aforementioned companies were obtained.
3.2 The Statistical Model and Estimation Procedure
The tests for statistical properties of the series were donein three stages:
(i) Test for Stationarity: this first stage of the analysis was
the test for stationarity of the individual economic series. This
test was conducted on each series using procedures for the two
variants of augmented Dickey-Fuller (ADF) tests, with one lagged
term, in EViews (Fuller, 1976).
(ii) Reconceptualisation of the Model as a Vector Autoregressive
System: having ascertained that all the series in the economic
model are non-stationary in their level, but stationary in their
first difference, it became obvious that least square technique
would not be appropriate for the estimation of the economic
model. Thus, bearing in mind the need to accommodate the
interdependence of relationships between most economic variables,
the economic model was re-conceptualised as a vector
autoregressive system (1), allowing for the possibility of
cointegration among the endogenous variables (Gujarati and
Sangeetha, 2007)
…………………………………………………...(1)
6
wherex is vector of deterministic variables, constant (C)
and/or trend;y is vector of I(1) endogenous variables – lnVOL, lnCMP,
lnDIV, lnEPS, lnPER, lnEARN, lnYIELD.B, and are matrices of coefficients to be estimated,
whilee is vector of stochastic residuals.
Terms in B give the influence of the associated deterministic
variables, while represent short-term elasticities of
response. And, where evidence of r<5 cointegrating relations
exists, by Granger causality theorem, ; in which is the
cointegrating vector (containing the long-run elasticities),
while elements of are the adjustment parameters in the vector
error correction model.
(iii) Test for Co – integration among Endogenous Variables: This
was implemented in EViews using procedures for Johansen (1992,
1995b) system based techniques. The test utilises a trace
statistic based likelihood-ratio (LR) test for the number of
cointegrating vectors in the system. In implementing the Johansen
technique however, two main issues were addressed. The first is
the choice of the optimal lag length in the VAR system, noting
that the lag length ought to be set long enough to ensure that
the residuals are white noise (EViews, 2009). Considering
limitations imposed by the data, this study stuck to the use of
one lag in the VAR. A second issue is whether deterministic7
variables such as a constant and trend should enter into the
long-run cointegrating space or the short-run model. EViews
provides facilities for conducting and comparing, cointegration
tests based on five scenarios that accommodates above
suggestions. These may be listed, from the most restrictive to
the least restrictive options, as follows:
Option A: Assumes no deterministic trend in the data, andallows no intercept nor trend in the cointegratingequation (CE) or test VAR;
Option B: Also assumes no deterministic trend in the data,and allows intercept (no trend) in the CE and nointercept in the VAR;
Option C: Allows for linear deterministic trend in the data,with intercept (no trend) in the CE and test VAR;
Option D: Allows for linear deterministic trend in the data,with intercept and trend in the CE but no trend inthe VAR;
Option E: Allows for quadratic deterministic trend in thedata, with intercept and trend in the CE and lineartrend in the VAR.
Since significant trends were not found in series in the
model (table 1), the final choice among the options was based on
application of the so-called Pantula principle (Johansen, 1992),
which permits joint test of the rank order of the long-run matrix
and the presence of deterministic components. This involved
estimating all the possible specifications, and conducting
8
Johansen's likelihood-ratio tests for the rank order of the long-
run matrix sequentially from the most restrictive to the least
restrictive specification. The first time the null hypothesis is
not rejected indicates both the rank order of the long-run matrix
and the appropriate specification for the deterministic
components (Gujarati and Sangheeta, 2007).
The final stage of the analyses, having established that more
than one cointegrating vector existed in the data, was to
estimate the restricted VAR in (1) using VECM facility in E-view
with two cointegrating restrictions imposed. The normalisation
adopted was in respect of the volume of shares traded and the
price earning ratio. This permits assessment of the long-run
influence of the dividend yield, earning yield, earnings per
share, current market price of shares, and dividend on these two
important variables.
(iv) Empirical ModelFollowing the usual approaches in literature, the long runperformance (volume traded) function adopted in this study isspecified in double logarithmic form as follows:
lnVOL = 0 + 1lnCMP + 2lnDIV + 3lnEPS + 4lnPER +
5lnEARN + 6lnYIELD + ………………………………………………………………………………….(2)
Where:
lnVOL = the logarithm of the volume traded of shares in eachmonth using volume traded at the end of each month as base value;
9
lnCMP = the logarithm of the current market price of shares usingthe current market price of shares at the end of each month asbase value;
lnDIV = the logarithm of the dividend. Dividend is also known asinterest. It is the interest on the invested capital.
Dividend (%) = Total Dividend attributable to ordinaryshare/Number of ordinary share ranking for dividend × 100%.
lnEPS = the logarithm of the earnings per share using the valuesat the end of each mont as base value;
lnPER = the logarithm of the price-earning ratio. PER indicatesthe number of years it would take for the share to earn theamount of its cost.
PER = Current Market Price /Earnings Per Share or Market Value ofShare/Total Earnings.
lnEARN = the logarithm of the earning yield. It is expressed as:
Earning Yield = earnings per share /current market price × 100%
Earnings = total earnings (profit after tax)/no. of ordinaryshare ranking for dividends.
lnYIELD = the logarithm of the dividend yield. Yield is thedividend paid by a company expressed as the percentage of thecurrent share price or calculated returns on invested capital.
Dividend Yield=dividend per share/current market price ×100%
js = are the coefficients of the jth variable in the model, while is the stochastic residual term
Results and Discussion
Unit Root and Co-integration Tests
10
The result of the Augmented Dickey-Fuller unit root tests is
summarised in table 1. The main evidence that emerged from the
ADF regressions of the unit root test is that all the variables,
except the index of dividend (lnDIV), price-earning ratio
(lnPER), and earning yield (lnEARN), had t-values that were lower
than the critical value for rejection of unit root at p<0.05 and
p<0.1, when examined at their levels. At their first difference
however, all the variables had t-coefficients greater than the
tabulated, which implied that the series are generally I (1)
series, and could not be appropriately included in their levels
in least square regressions. Thus, the appropriate modeling
technique for the performance of agricultural based companies in
the NSE would be to specify a VAR system as in 1, and since
evidence of co-integration exists, the relations was estimated by
VECM.
The results of the co – integration test for all possible
specifications supports the specification with no intercept and
no trend in the CE or VAR. An estimation of the specification in
Table 2 indicates that the null hypothesis of no co-integration
equation (CE) is rejected at 1% and 5% level of significance. The
null hypothesis of at most one CE is rejected at 1% and 5% level
of significance. However the null hypothesis of no more than two
CE could not be rejected at 1% and 5% level of significance. By
this and the specification stated by the Pantula principle, the
11
Johansen (1992, 1995a) based likelihood ratio tests revealed that
two co-integrating equations exist among the variables in the
economic model.
The Vector Error Correction Model
The normalised cointegrating vectors in the long run VECM are
presented in table 3, while table 4 presents the short run
components. The estimated coefficients in the equilibrium
performance model are quite plausible, and all variables had long
run elasticities that are consistent with economic theory. A 1%
change in dividend yield causes the volume of shares traded to
increase by about 536%, while inducing a reduction in price
earning ratio by 81%. This is expected since dividend yield
represents the financial returns on investment which after
adjustment for anticipated changes in the value of money and for
the degree of risk is the major criterion in the selection of
investment, so if the change is favourable, the share attracts
more buyers and consequently increases volume traded. As regards
price earning ratio which indicates the number of years which it
would take for the share to earn the amount of its cost, an
increase in dividend yield which leads to an increase in volume
of shares traded will expectedly result in a decrease in price
earning ratio. A 1% increase in earning yield leads to a decrease
in volume of shares traded by about 2.28% and also a decrease in
12
price earning ratio by 2.82%. This change in volume of shares
traded as a result of change in earnings is not too pronounced,
it occurs when there is a drop in the earnings of the company or
when buyers are skeptical about the financial statement of the
company even when it looks favourable. A 1% change in earnings
per share induces a decrease in volume of shares traded by about
0.44%, while increasing price earning ratio by about 3.06%. This
is so because earnings per share relate to earnings of the
company and it is necessary to examine a company’s asset
position: the real vital factor being its earning power which
provides valuable information to actual and intending
shareholders. The import of this is that a decrease in the
earnings per share will lead to a minute reduction in volume
traded and consequently increase the number of years which it
would take for the share to earn the amount of its cost. A 1%
change in current market price of shares causes an increase in
volume of shares traded by about 524%, while causing price
earning ratio to drop by about 80%; as long as there is an
increase in the volume of shares traded as a result of change in
any of the independent variables, a drop in price earning ratio
will be experienced. A 1% change in dividend decreases volume of
shares traded by about 548% while increasing price earning ratio
by about 85%.
Considering the VECM results in table 4, the variables considered
accounted for about 25.6% of the variations in the short run
13
volume traded. The adjustment coefficient for volume traded
(0.25) implies that adjustment to any disequilibrium caused by
shocks to the volume of shares traded is corrected within about
1/0.25 months (4 months). Such shocks may be due to fraudulent
acts of the company management who may send out their own
personnel to buy up the shares in such volumes as to give the
impression that the shares are doing well in the market in order
to attract unwary customers (buyers). The adjustment coefficient
for dividend yield as it affects volume traded (0.0082) implies
that adjustment to any disequilibrium caused by shocks to the
dividend yield is corrected within about 1/0.0082 months (122
months or about 10 years).
Comparing the short run and long run volume traded response
elasticities, results in this study show that the long run
effects of earning yield, earnings per share, and dividend
depreciation are generally larger (and relatively elastic) than
the short run response which is inelastic. When this result is
appraised against the background that the adjustment
coefficients in the VECM are tending more towards zero, it
becomes obvious that initial changes (reduction) in volume of
shares traded that may arise from earning yield or dividend
depreciation tend to take so many months before they steady out.
This situation has always over time been the bain of attracting
investment to the agricultural sector even in the Nigerian Stock
Exchange.
14
Summary, Conclusion and Recommendations
Modeling of performance (volume traded) of shares in the
agricultural sector of the Nigerian Stock Exchange are better
cast within the simultaneous equations frameworks, such as the
VAR or VECM, so as to appropriately incorporate the structural
interdependence among the variables. The adjustment coefficients
associated with error correction terms in the model were very
much less than zero. Thus, the variables do not adjust very
quickly to short run shocks in equilibrium performance relations,
taking about four months to ten years to adjust. This is in
agreement with happenings in the stock market towards the end of
2007 and for the better part of 2008
(www.stockmarketnigeria.com). To this effect, investors in agro
based companies are advised to engage in long term investment
rather than short term investment as the slide in the capital
market is the normal trend in the capital market, and the bearish
period will soon give way to the bullish (rise in market) times.
The agricultural sector any day provides opportunities for long
term investment. This work has drawn attention to the price
earning ratio as a veritable tool in stock analysis. This is
because happenings in the stock market towards the end of 2007
and in the year 2008 have shown that more than ever, investors
now would realize that to thread a safer path is to ‘play more to
the rules’. As such some of the basic techniques that have been
15
tested by time and established as best practice should guide
every investment decision. This would enable a healthy allocation
of financial assets for the most advantageous gains. The use of
basic mechanics of stock analysis would help in achieving that.
Now that a ‘moving with the crowd’ strategy has dealt a blow to
the undiscerning, there is the need to take on a more purposive
stance in allocation of assets, this will help to prevent over
concentration of investments in the banking and oil sectors.
