ABSTRACT
In this paper I will try to apply an algorithm of hierarchic classification of the economic and financial performance for a group of companies in the
chemical field, listed with the New York Stock Exchange (NYSE), a classification which will be performed taking into consideration the Return on Equity
(ROE), Net income, Economic Value Added (EVA), EVA/Equity and Stock Price. The classification will be performed using the cluster analysis.
KEY-WORDS: Return on equity (ROE), Economic Value Added (EVA), cluster analysis, Nearest Neighbor Method, Ward's linkage.
JEL classification codes: M21; M41; M49.
Introduction ˝The financial rate of return” is the result of the percentage ratio of the net income associated to accounting year (Romanian acronym Rn) and the
value of the firm-owned equity (Romanian acronym CP). The Anglo-Saxon equivalent is the “ROE” index - “Return on equity (return of company-owned
equity).˝1
Rrf = CP
Rn × 100˝
„Return on equity (ROE) is one of the major indexes monitored by investors and management. Using this rate, investors can appreciate to what
extent their investment is profitable or not. In the event that the return on equity is higher than the cost of the owned equity, then, by the performed activity,
the company creates an additional value for shareholders.”2
The economic value added (EVA). ˝The economic value added index (EVA) is a privileged index for performance evaluation, which integrates the
assembly of resource consumption (operational, cost of borrowed capital, and the cost of cost of the owned equity).
EVA simply requires the supplementation of calculation by taking into account the cost of the owned equity.3”
˝The recent disturbances in the financial world only increased the distrust in the „commercial” models used as a basis for measuring the performance
and hierarchy of companies.
A positive value of the EVA index signifies achieving wealth for shareholders in addition to the capital remuneration. A negative value shows the
fact that the company fails to cover the cost of capital from the achieved operational result. In other words, the company loses money even if it reports a
positive accounting result.˝4
„Any company has to achieve, following its activity, a mean rate of return on capital markets, a rate determined under comparable risk conditions. If
a company cannot generate a minimum value of return requested by shareholders, then the said shareholders will place their capital in other fields of activity
or other companies5”.
Distances between items. ˝A presentation of the usual methods for calculating the distances between items (elements or already constituted groups)
follows. The selection of a specific distance modifies the groups which are constituted.˝6
The cluster analysis. ˝The cluster analysis plays an important role within the methods of uncontrolled recognition of forms (also known as non-
supervised learning methods). The purpose of the cluster analysis is represented by data classification (observations or forms) in information structures which
are significant, relevant, called classes, groups or clusters.
Therefore, an essential notion used by the cluster analysis is the cluster. A cluster is defined as a subset of the initial aggregate of items (notes) the
property of which is that the degree of dissimilarity between any of two items which belong to the cluster is lower than the degree of dissimilarity between any
other item belonging to the cluster and any other item which does not belong to that cluster. It is necessary to mention a series of technical explanations.
Firstly, to evaluate the distance (dissimilarity) between items (companies listed in category I) or between clusters, the Manhattan distance will be used. The
Manhattan distance, also called the rectangular distance, the “City-Block“ distance or norm of type L1, is calculated as a sum of the absolute values of the
differences of coordinates of the two items or the two analyzed variables.

Secondly, we will use Ward’s method, as a method of hierarchic classification by aggregation. This method is considered the most efficient and the
highest performance method of all the “algorithms” of hierarchic classification as it the only one which explicitly treats the problem of classes
homogenization, that is of minimizing of intra-cluster variability: at every step the two clusters - for which the variability of the resulted cluster is the lowest
of all the possibilities of clusters fusion – are merged. An important premise of Ward’s method is represented by the break-out of the total variance into intra-
cluster variance and inter-cluster variance.˝7
The nearest neighbor method. ˝The distance between two groups is the minimum distance between two elements of the groups (distance between
the nearest elements of different classes). This method uses the calculation of the distance between two groups as the maximum distance between two
elements of the groups (distance between the farthest elements of different classes). The advantage of this method is that it does not agglomerate groups linked
by a chain. Also, the achieved grouping better corresponds to the intuitive grouping (performed by a human operator).˝8
Ward's linkage method. ˝Ward’s linkage is based on the growth of “sum of squares of errors” after the groups are merged into one single group.
Ward’s method selects the groupings which minimize the growth of sum of squares of errors.˝9
Dendrogram. ˝As a result of the algorithm, the classification ranking (dendrogram) is achieved. By the horizontal sectioning of the dendrogram, a
partition of the aggregate of the classified elements is obtained. The components of the partition are the needed classes.˝10
Study of case
To study the companies operating in the field of chemical production, I used the data of a sample of 31 companies, my purpose was to make the
classification of these companies dependant on 5 variables: ROE, Equity, Net income, EVA and Stock Price.
Descriptive Statistics N Range Minimum Maximum Mean Std. Deviation Variance Skewness Kurtosis
ROE 31 9.10 0.0003 9.15 0.50 1.608 2.588 5.439 29.974

Valid N 31
Table No.1. My own calculations For the considered 31-company sample, one can find that the mean value of the rate of return is about 50% (0.50), the minimum value being 3%,
reported for FLOTEK INDUSTRIES INC – KPI, and the maximum value is 910%, reported for DOW CHEMICAL – KPI, with a standard deviation of 1,60,
the studied sample displays positive asymmetry, which means that values of the ROE index are in excess of the mean reported value, that is the considered
companies form a heterogeneous group.
Also, the asymmetric distribution of the companies in the chemical industry has a leptokurtosis character, as resulted from the kurtosis, the value of
which is much higher than the same index specific to the perfectly symmetric normal distribution, the value of which is 3.
From the Equity variable standpoint, the analyzed companies report a mean of 5472,06 million $, having a value range from 92.00 million $ -
reported for company CHASE CORP- KPI and the maximum value of 84207.00 million $ - for company FLOTEK INDUSTRIES INC - KPI. The sample of
considered companies is very heterogeneous because the mean square deviation is very high, amounting to 14990.692 million $, the distribution being
asymmetric, and it advances to values higher than the mean liabilities, thus it has a leptokurtosis character, too.
Analyzing the Net income variable, the 31-company sample in the field of chemical industry reported a mean Net income of 1321.65 million $, with
a mean square deviation of 4109,13 million $, the minimum Net income being reported for company LANDEC CORP - KPI, and the maximum Net income
being reported by company DOW CHEMICAL - KPI, the distribution of values being asymmetric towards values higher than the mean Net income, having a
skewness of de 5.23, thus it has a leptokurtosis character with a kurtosis of 28.38.
For the EVA variable, the analyzed companies report a mean value of 337.53 million $, the minimum value being -68.49 million $, reported by
company ASHLAND INC – KPI, and the maximum value is 2331.34 million $, reported for company DU PONT (E I) DE NEMOURS – KPI. The value of
the mean square deviation is 523.317 million $, the value of skewness is 2.383 million $, and the value of kurtosis is 6.339 million $.
As the value of kurtosis is low, we can state that, from the EVA index standpoint, the sample is approximately symmetric, the form of distribution
having a mezzo-kurtosis character.
For the Stock Price variable, the analyzed companies report a mean value of 56.17 $, the value of the minimum Stock Price is 8.56 $ - being reported
by company LANDEC CORP – KPI, and the value of the maximum Stock Price maxim is 216.60 $, bei9ng reported by company NEWMARKET CORP –
KPI. The value of the mean square deviation is 48.285 $, the value of skewness is 2.002 $, and the value of kurtosis is 4.657 $.
From the Stock Price variable standpoint, the considered companies form a homogenous group.
For the sample of analyzed companies, the graphs below show that they have distributions different from the normal traditional distribution
considered in the classical econometrics theory.

Elimination of incongruous data
The intended purpose is to identify the classes of companies comprised of companies which are similar from the standpoint of the five tracked indexes,
which are different from the companied in the other classes. To perform a classification by classes, I have used the cluster analysis, the first stage being the
elimination of the dissimilar companies in the analyzed group which report high performance as compared to the rest of the companies. The first stage of the
scientific approach is to perform the classification of companies taking into account the single linkage method to detect the incongruous data in the initial data
matrix. As the variables initially analyzed are measured on different ranges as order of measure, to provide the comparability of information in the company area
(the 31 companies can be considered to form an area named as a rule area of individuals, the classification being done for its elements), I have performed the
standardization of the initial values.
Therefore, the classification process is performed for the standardized values, thus providing the comparability of companies dependant on the analyzed
variables.
Detection of incongruous data is done by applying the superior hierarchical classification, using the single linkage method, taking the square Euclidian
distance as a measure of the dissimilarity among companies.
Based on the classification table and dendogram in Annex No.1, one can find that, of the 31 analyzed companies, the prominent companies are DOW
CHEMICAL – KPI and FLOTEK INDUSTRIES INC – KPI, which are the highest performance ones of the initially analyzed aggregate. The research progress
continued by the elimination of these entities – as shown in the classification dendogram, using the single linkage method, each time the two companies will be
located in a different class, which, though allowed by the theoretical results obtained in the field of classification techniques, is not just from the interpretation
standpoint, as at the limit, each company can be included in a distinct class. In this way one will obtain a subset of the aggregate of the parts of the initial
company list, that is 31 subsets having each an element, however, the consideration of each company as being part of a specific class does not bring any
informational gain.
The classification of the 29 companies left in the initially analyzed 31-company sample is performed by using the classification method proposed by
Ward, taking the square Euclidian distance as the measure of the dissimilarities among the classified items, as this classification method is the best fit for
performing the distribution of companies by classes because it takes into account the variability inside classes, a company being allocated to the class toward
which the space density of companies is minimal .
