Abstract 

This study examines the factors influencing stock prices of Bulgarian non-financial listed 
companies, employing descriptive statistics, correlation model, panel regression model, and 
Granger causality test for the period 2015-2022. The research investigates the impact of computer 
software assets, intellectual property rights, goodwill, earnings, book value, and dividend on stock 
prices. The results indicate that software products per share (SFS), book value per share (BVS), 
dividend per share (DPS), and earnings per share (EPS) have statistically significant impacts on the 
stock prices of non-financial publicly traded companies in Bulgaria. Intellectual property rights per 
share (IPS) and goodwill per share (GPS) do not significantly influence stock prices. Additionally, 
the study highlights the dynamic relationships and causality between these variables and stock 
prices over the examined period. This research not only contributes to the academic discourse on 
financial market dynamics but also offers pragmatic insights for investors and policymakers. As 
financial markets continue to evolve, this research provides a timely and relevant contribution to 
the ongoing dialogue surrounding stock price determinants and their implications for market 
participants. 

 
Keywords: Bulgarian stock exchange, Intangible assets, Panel data, Panel regression analysis, Stock prices.

1. Introduction 

The main purpose of financial reporting is to assist investors in making informed economic decisions and 
assessing the value of a company. Exploring and understanding the main factors that influence stock prices is 
paramount for investors, policymakers, and stakeholders.  Certainly, the correlation between accounting data and 
the financial markets is among the most extensively analyzed and debated subjects in the realms of financial and 
accounting literature. In particular, intangible assets such as computer software and intellectual property have gained 
unprecedented significance, especially in their contribution to the computerization of inventory management and 
production processes within the manufacturing sector. Intangible assets play a pivotal role in businesses' future 
growth and success. Companies with more intangible assets tend to exhibit greater innovation and competitiveness, 
resulting in augmented market values. Furthermore, the size of intangibles is positively correlated with the market 
value of a firm. Consequently, both companies and investors need to consider the extent of intangible assets when 
evaluating the market value of a company. Basheva (2017) suggests that the adoption of consistent and universal 
accounting standards will improve the effectiveness of capital markets by promoting the comparability of accounting 
information in financial statements. 

The main goal of this research is to examine the effect of intangible assets on the share prices of non-financial 
public enterprises listed on BSE (Bulgarian Stock Exchange). The following hypotheses are developed:  

H1: Computer software assets have a significant influence on the share prices of listed companies in Bulgaria. 
H2: Intellectual property rights have a significant influence on the share prices of listed companies in Bulgaria.  
H3: Goodwill have a significant influence on the share prices of listed companies in Bulgaria.  
H4: Earnings per share, book value per share, and dividend for share have a significant influence on the share prices of listed 

companies in Bulgaria.  
The research underscores the critical role of specific intangible assets and traditional financial metrics in shaping 

stock prices. These insights offer valuable implications for investors, policymakers, and stakeholders in 
understanding and predicting stock market behavior in emerging markets like Bulgaria. 

 
2. Literature Review 

Intangible assets have a significant impact on the market value of firms (Qureshi and Siddiqui, 2021; Pan, 2022; 
Lim and Jones, 2023).  Ionita and Dinu (2021) find that intangibles like R&D and patents do not have a positive 
impact on firm value, but IT programs do have a positive and significant impact on firm value.

Oryina and Suleiman (2020) investigate market value relevance of intangible assets in Nigeria and prove that 
computer software is positively related to market value. Also, intellectual property has a significant effect on the 
market price per share. Aulia et al. (2020) confirm that most investors use and pay attention to the earning value and 
more to intangible value as a basis for consideration of their investment decision making on the Indonesian stock 
exchange.  Paolone et al. (2020) find that intangibles are positively related to security prices of Italian stock market 
for the period 2010-2018. The results show that the role of intangibles increase. Kimouche and Rouabhi (2016) 
establish that goodwill and book values are more correlated with market values compared to intangible assets and 
earnings for French companies. The authors conclude that intangibles enhance the value relevance of accounting 
data. Similarly, Al-Ani and Tawfik (2021) confirm that intangible assets improve the value relevance of accounting 
data positively in UAE and negatively in Kuwait. The results suggest that intangible assets can improve the value 
relevance in emerging markets, such as GCC. 

Dancaková et al. (2022) examine the impact of intangible assets on a firm’s market valuation in France, Germany, 
and Switzerland. The results suggest that intangible assets have a positive effect on companies' market value 
although investors still prioritize profitability over intangible assets. Abdulhadi et al. (2022) prove that the effect of 
intangible assets on the stock prices of active firms in Iran is positive and significant, while it is negative and 
significant in the Iraq. Andersson and Saiz (2018) establish that that the significance of investment in intangible 
assets has grown in the euro area. Vasconcelos et al. (2019) examine the correlation between intangible assets, market 
value and the macroeconomic environment of German, Portuguese and English public firms spanning the period 
from 1999 to 2016. Their results indicate that the comprehension value is positively and significantly correlated to 
the market value of these companies. Furthermore, the researchers find that the intangible capital and the 
intangibles-driven-earnings exhibit positive correlations with research and development expenditures as well as 
general administrative procedures. Owiredu et al. (2014) investigate whether the concentration of intangible assets 
on a firm's balance sheet influences the volatility of its stock price. The results indicate that in the basic 
pharmaceuticals sector, there is a positive correlation between the concentration of intangible assets and stock price 
volatility. 

Pereira da Silva (2019) analyses value relevance of accounting indicators in European market. Results show 
strong evidence supporting value relevance of book value and earnings. Jaba et al. (2016) conduct a statistical 
evaluation of the value relevance of accounting data for companies traded on the Bucharest Stock Exchange. Their 
findings indicate that accounting information has value for investors. Glezakos et al. (2012) prove that earnings per 
share and book value per share have an influence on stock prices in the Athens Stock Exchange. 
 

3. Bibliometric Analysis 
Bibliometric analysis is a popular and reliable method for examining and interpreting vast volumes of scientific 

data. To construct and visually represent bibliometric networks, the VOSviewer software tool is used. Keywords co-
occurrence analysis is frequently employed to assess the strength of links between various keywords across numerous 
documents. Applying VOSviewer, we generate a map that illustrates the relationship between the keywords: „stock 
price“ and „ intangible assets“.  A total of 1 372 documents were retrieved from Scopus database in March 2024. The 
selection is limited to the following subject areas: Business, Management, and Accounting (1,080), as well as 
Economics, Econometrics, and Finance (770). The final number of documents found is 1 250. In all the literature 
collected, a total of 3 120 keywords emerged. VOSviewer software identified 176 keywords that appeared more than 
5 times.

Figure 1 presents the visualization map of the keyword network. The co-occurrence of keywords formed eight 
distinct clusters. There is a significant correlation between the keywords in each cluster. The main elements within 
these eight clusters are as follows: intangible assets; investments; value relevance; disclosure; research and 
development; intellectual capital; innovation; and financial performance. The distance between the two circles 
illustrates the proximity of the two keywords. The lines connecting them in the figure represent the relationships 
between the elements. Additionally, a thicker line indicates a stronger relationship between the items. The link 
strength of the keyword "intangible assets" is 148 points. 

 
4. Methodology and Data  

This research presents an empirical analysis of the effect of intangible assets on the share prices of the capital 
market in Bulgaria. It uses annual panel data spanning from January 1, 2015, to December 31, 2022. Employing panel 
data enables the observation of a particular variable at one specific moment and simultaneously observes another 
variable at another moment, facilitating the exploration of various relationships, interactions, and patterns 
(Kapitanov, 2021). 

Table 1 lists the accounting and financial variables used in the empirical analysis.

This study uses several accounting metrics, including intellectual property rights per share, software products 

per share, Goodwill per share, earnings per share, book value per share, and dividend per share. These variables were 
chosen based on previous research and data availability for computation (Stoykova, 2022). The accounting data were 
gathered from the individual annual financial statements of the examined companies. Moreover, the Bulgarian capital 
market mandates listed companies to disclose detailed quarterly and annual financial statements. Consequently, all 
accounting information was sourced from the Bulgarian Stock Exchange (BSE). Table 2 outlines the explanatory 
variables utilized in the regression equation along with the anticipated sign for each of their coefficients.

Goodwill per share (GPS) Positive + 

 

The sample for this study includes 20 individual joint-stock companies across various sectors in Bulgaria. 
Consistent with Hellström's (2006) methodology, financial firms are excluded due to notable differences in structure 
and accounting compared to non-financial entities (Hellström, 2006; Stoykova, 2021). All included companies are 
publicly listed on BSE. Market indices such as SOFIX, BGBX40, BGTR30, and BGREIT are based on the market 
capitalization of the common stock issued by chosen Bulgarian companies. These companies must meet specific 
criteria for liquidity, market capitalization, and shareholder count to be included in these indices. This study focuses 
on companies from diverse sectors of the Bulgarian economy, including manufacturing, professional activities and 
research, transport, storage and post, real estate operations, hotels and restaurants, extractive industry, and 
construction. These 20 companies were chosen because they provide complete accounting data spanning the analysis 
period from 2015 to 2022. 

Before conducting the empirical analysis regarding the influence of accounting data on share prices, it is 
necessary to apply a Panel Unit Root Test. This test is used to assess the stationarity of the analysed panel data, 
determining whether the panel is stationary or non-stationary.  

Correlation model and Granger causality test are employed to test the relationship between the examined 
variables. Regression analysis is commonly used to determine the presence and direction of relationships between 
two or more variables. For empirical analysis purposes, Ordinary Panel Least Squares Model is applied. The simple 
panel regression can be expressed by the following formula: 

 𝑦𝑖𝑡 = 𝛼 + 𝛽𝑋𝑖𝑡 + 𝜀𝑖𝑡              (1) 
The following explanatory legend applies to Equations (4): 

For i = 1, 2, ...., N и t = 1, 2, ...., T.

Where: 

𝑦 – dependent variable; х – independent variables; 𝑡 - reflects the time range; T - the number of periods; 

𝑖 - reflects the spatial range; N - the number of individual or spatial data; 𝑎 - intercept of the model; β - 

unknown parameter subject to calculation; ε - error. 

In panel regression, the model error ε𝑖𝑡 combines the error associated with temporal data and the error 
associated with spatial data (Nenova, 2020). 

 

5. Empirical Analysis 
First, the panel unit root test was applied. The results of Levin, Lin & Chu t panel unit root test show that all 

the panel time series are non-stationary at level (zero order), thus requiring acceptance of the null hypothesis 
indicating the presence of non-stationarity in the variables under study at level (0) (p-value > 0.05). Consequently, 
transformation into the first difference is necessary. The first difference of all examined variables is stationary, so the 
empirical analysis can be proceeded. 

Figure 2 presents graphically the mean values by date for each of the examined variables. 
The trend observed for software products is upward for the period 2018-2022, suggesting that enterprises are 

allocating increasing funds towards the implementation of digitalization and innovation (Figure 2). On the other 
hand, the mean values of intellectual property per share and goodwill per share are relatively stable and unchanged 
for the period 2018-2022. Moreover, the highest mean value was registered for book value per share (24.2 for 2022), 
whereas the lowest was observed for IPS (0.003 for 2020, 2021, 2022). The highest mean value of stock prices is 
observed in 2022 (17.1), while the lowest mean value of SP is registered in 2019 and 2020. This could be attributed 
to the COVID-19 pandemic that has started in March 2020, which negatively affected capital markets.  Table 3 
presents the descriptive statistics for the whole sample.

The mean stock price (SP) is 14.02913, indicating a relatively high average. The skewness value of 2.31 suggests 

a moderate positive skewness, implying a distribution that is slightly skewed to the right. The kurtosis value of 9.21 
indicates a distribution with heavier tails compared to a normal distribution. The median value is 6.20, indicating 
that half of the observations fall below this value. The maximum value is 112.00 and the minimum value is 0.135.  

The mean software product per share (SFS) is 0.0431, with a relatively low standard deviation of 0.1179. The 
skewness and kurtosis values are both high, indicating a distribution that is highly skewed to the right and has heavy 
tails. The standard deviation is 0.1179, suggesting a relatively low degree of variability. The Jarque-Bera statistic is 
844.69 with a p-value of 0.000, indicating a departure from normality. The mean intellectual property per share (IPS) 
is 0.0103, with a low standard deviation of 0.0533. The skewness and kurtosis values are extremely high, indicating 
a highly skewed and leptokurtic distribution. The maximum value is 0.48280.  The mean value for goodwill per share 
(GPS) is 0.037, with a moderate standard deviation of 0.1349. The skewness and kurtosis values suggest a 
distribution that is moderately skewed to the right and has moderate tails. The Jarque-Bera statistic is 1631.40 with 
a p-value of 0.000, indicating a departure from normality. The mean book value per share (BVS) is 13.22, with a 
substantial standard deviation of 28.38. The mean dividend per share (DPS) is 0.2758, with a moderate standard 
deviation of 0.8855. The skewness and kurtosis values of DPS show a distribution that is moderately skewed to the 
right and has moderate tails. The mean earnings per share (EPS) is 1.2095 and the maximum value is 57.87126. The 
Jarque-Bera statistic of EPS is 39436.49, indicating a departure from normality. Table 4 presents the correlation 
matrix. A strongest positive correlation is observed between stock price and dividend per share (0.572148). Also, a 
positive moderate correlation is revealed between stock price and software product per share (0.501062). The 
correlation coefficient between stock price and book value per share is 0.400182, suggesting that the relationship 
between these two variables is moderate and positive. Moreover, as the earnings per share rise, there is a 
corresponding increase in the stock price. The strongest correlations observed involve DPS, BVS, and SP.

The Ordinary Panel Least Squares model is applied and the results are presented in Table 5. The results of the 
panel regression show that the accounting variables can have a statistically significant impact on the stock prices 
(SP) of the Bulgarian Stock Exchange for the period 2015-2022.  The highest statistically significant coefficient in 
the model is for software products per share (SFS) and it is 44.96278. These results show that a one-unit increase in 
the SFS is associated with an increase in the dependent variable SP by approximately 44.963 units. The coefficient 
for this variable is positive, aligning with the expected sign (+). On the other hand, the coefficients for the other two 
intangible assets (IPS and GPS) are not statistically significant. This suggests that intellectual property rights per 
share (IPS) and goodwill per share (GPS) are not significantly related to the dependent variable (SP).  

The coefficient for BVS is 0.130089, and it is statistically significant at the 1% level (p-value = 0.0095). These 
findings suggest that book value per share is a significant accounting variable for determining stock prices alongside 
other accounting variables incorporated in the model. The sign of this coefficient is positive and it matches the 
expected sign. This implies that high BVS is directly related to stock price; that is, the higher the book value per 
share, the higher the stock price. These results reconfirm findings obtained by other researchers (Malhotra & 
Tandon, 2013; Almumani, 2014; Warrad, 2017). The coefficient for earnings per share (EPS) is 0.262823, and it is 
statistically significant (p-value = 0.0003). A one-unit increase in EPS is associated with an increase in SP by 0.262823 
units. The coefficient for EPS is positive, aligning with the expected sign.  Other researchers have also established a 
positive and statistically significant correlation between EPS and SP (Kwon, 2009; Khanna, 2014; Shehzad & Ismail, 
2014). The coefficient for dividend per share (DPS) is -2.829, and it is statistically significant. DPS has a negative 
impact on stock prices, indicating that high values of DPS are inversely correlated to stock prices (i.e. an increase in 
the dividend amount results in a decline in the stock price). The sign of this coefficient does not align with its 
anticipated positive sign. These findings align with those of numerous research papers (Srinivasan, 2012; Malhotra 
& Tandon, 2013; Neupane, 2020).  In summary, the results show that software products per share (SFS), book value 
per share (BVS), earnings per share (EPS), and dividend per share (DPS) are statistically significant predictors of 
stock price (SP). The regression model employed on the panel data can be expressed by the following equation (in 
the equation, the statistically significant coefficients for each individual variable are indicated in bold): 

𝐷(𝑆𝑃)  =  0.310009012703 +  44.962775713 ∗ 𝐷(𝑆𝐹𝑆)  +  16.5018171526 ∗ 𝐷(𝐼𝑃𝑆)  −  18.0060414184 ∗

These results validated the findings from the previous tests. Therefore, there is evidence to reject the null 

hypothesis that changes in software products per share (SFS) do not provide useful information about future changes 
in SP. In summary, software products per share (SFS), book value per share (BVS), dividend per share (DPS), and 
earnings per share (EPS) granger cause changes in stock price (SP). 

Considering the results from correlation matrix, panel regression model and granger causality test, we can except 
H1 and H4. SFS, EPS, BVS, DPS have an impact on stock prices. Contrarily, we have enough evidences to reject H2 
and H3 because GPS and IPS have no statistically significant impact on stock prices. 
 

6. Conclusion 
The relevance of accounting information describes how investors respond to its disclosure. This reaction 

demonstrates the importance of accounting information in the investment decision-making process, underscoring its 
value for investors (Scott, 2015). This empirical analysis assesses how intangible assets and other accounting 
variables affect the stock prices of non-financial listed companies on the Bulgarian Stock Exchange between 2015 
and 2022. The study employs descriptive statistics, correlation analysis, panel regression models, and Granger 
causality tests, to test the relationships between stock prices and key accounting variables. The results of the 
descriptive statistics reveal upward trends in software products per share (SFS) from 2018-2022, while intellectual 
property per share (IPS) and goodwill per share (GPS) remain relatively stable. The highest mean value is observed 
for book value per share (BVS), indicating its significance in market valuation. Correlation analysis reveals a moderate 
positive relationship between stock prices (SP) and variables such as dividend per share (DPS), book value per share 
(BVS), and software products per share (SFS). The results of the panel regression model show that software products 
per share (SFS), book value per share (BVS), earnings per share (EPS), and dividend per share (DPS) are statistically 
significant predictors of stock prices. The study affirms that these accounting variables are beneficial for investors 
and analysts in examining and assessing companies across various sectors, thereby aiding informed economic 
decision-making. The study results demonstrate the value of accounting information for investors, albeit with 
considerable variation over time and among different companies. However, the results also reveal that intellectual

property per share (IPS) and goodwill per share (GPS) lack statistical significance, challenging the hypotheses 
positing their impact on stock prices. Additionally, the results from the Granger causality test validated the findings 
from the previous tests (correlation matrix and panel regression model). In summary, based on the results obtained, 
Hypothesis 1 (H1) stating that computer software assets have a significant influence on the share prices of listed 
companies in Bulgaria is accepted. Hypothesis 2 (H2) positing that intellectual property rights have a significant 
influence on the share prices of listed companies in Bulgaria is rejected. Hypothesis 3 (H3) that goodwill has a 
significant influence on the share prices of listed companies in Bulgaria is rejected. Hypothesis 4 (H4) suggesting 
that earnings per share, book value per share, and dividend per share have a significant influence on the share prices 
of listed companies in Bulgaria is accepted. This research gives practical insights into the Bulgarian stock market 
and the findings help investors, policymakers, and analysts better understand the factors shaping stock prices.  The 
primary focus for future research related to this issue involves exploring the application of artificial intelligence (AI) 
in financial reporting and forecasting, leveraging AI techniques, such as machine learning algorithms and natural 
language processing.
