1. Introduction: Manufacturing Dynamics & The Identification of Unsung Sectors

The enormous presence of the manufacturing sector in India has often invited many debatable research conclusions among researchers. It was Ahluwalia (1985) who observed that total factor productivity growth (TFPG) in the manufacturing sector in India was not robust during the post reform period of 1991. But the other research contributions have completely rejected the claim made by the former researcher. The research contributions of Balakrishnan & Pushpangadan (1994) claim that TFP growth in the Indian manufacturing sector stood strong and created a positive impact on the Indian economy. Several studies of such kind have disclosed that the manufacturing sectors that were liberalised in terms of FDI and Tariff, experienced 15 percent and 20 percent productivity growth during post reform period (Sivadasan, 2003).

This increase in productivity growth has led to a momentum of skill intensive industries in India which would gradually convert India to a manufacturing hub. In the study put forward by Sakhardande & Gaonkar (2021) twenty-five sectors were recognized to be under Make in India (MII). Apart from that, among these sectors, five sectors come under the category of superstar sectors (DPIIT, 2014). But there are many other performing sectors in the category of manufacturing sector in India, which does not find a place in above mentioned studies.

This has made the researcher think about such sectors and to study their growth prospect for the prospective investors to invest in them. The share prices are uncertain and there is all possibility of fluctuations. In this scenario, it would be useful for the investors in attaching the share price to a component that displays the strength of a company. The robust performance of a company is disclosed by its accounting variables, and this is made as a component in this research that establishes a relation with share price.

The Nine Unsung Manufacturing Sectors & Sample Selection

The researcher attempted identifying nine sectors based on the revenue they generated for the past 24 years (1997 to 2020). Among these nine sectors, eighty-four companies based on market capitalisation were selected. The market capitalisation indicates the total value of a firm, and is an indicator of business valuation preferred by the investors for their investment purpose (Jaya & Sundar, 2012). Further the market capitalisation also has a positive association with profitable accounting ratios (Prasad, 2015).

1. Aluminium
2. Cement
3. Commodity Chemicals
4. Heavy Electrical Equipment
5. Industrial Machinery
6. Other Electrical Equipment
7. Other Industrial Goods
8. Other Industrial Products
9. Plastic Products

CMIE prowess data for the period 1997 to 2020 displays an impressive performance of these sectors in terms of revenue generated by them for the Indian economy. Despite their supreme performance in terms of growth in revenue, even during the pandemic, they could not find a place in the studies that propagated future prospects of the manufacturing sector in India. Hence the researcher has coined the term unsung sectors for these nine sectors mentioned in the study.

Three-Fold Research Objectives:

  1. To determine the accounting variables that have an association with the share price of these unsung sectors.
  2. To determine the relation of share price and accounting variables on a pre and post analysis based on the global crisis which occurred in 2008 (the sub-prime crisis).
  3. To test the sufficiency of variables to remove multicollinearity and eliminate time-series autocorrelation.

Note: This study focuses its attention on the entire nine sectors as a whole rather than emphasising on a specific or individual sector.

2. Theoretical Framework & Literature Review

There are numerous studies that were performed in finding out the relation between share price and accounting variables. All these studies emphasised on several accounting variables. This has formed the basis for the researcher to select the accounting variables for the study.

Among the six accounting variables considered for the study, Book value per share (BPS), Earnings per share (EPS), Dividend per share (DPS) and profit were also considered in the landmark studies of Ball & Brown (1968) and Ohlson (1995). The study conducted by the former was wrapped with the conclusion that profit is value relevant towards the stock price. Whereas the latter in his study proved that all financial information disclosed in balance sheet and income statement has an impact on share price.

The other two variables used in this study are Return on Total Assets (ROA) and Return on Capital Employed (ROCE). These variables were used in the study conducted by Lev (1989), Penman (1992), and Marx (2010). All these studies exposed the fact that these accounting variables have explanatory power on stock price.

The Ohlson Valuation Model (1995):

The methodology used in the above studies for establishing an association with share price was the Ohlson Model. It has been framed as follows:

Pt = β0 + β1Bit + β2Xit + β3vit + eit

Based on this Ohlson equation, there were several studies that has established association with accounting variables and stock price. This equation was used in the studies of Ali & Hwang (2000), Barth, Landsman, & Lang (2008), Dong & Stettler (2011) and Clarkson, Hanna, Richardson, & Thompson (2011). In all these studies, accounting variables and share price are based on time elements. Hence time series analysis is implemented along with Ohlson Model for a conclusive solution.

3. Empirical Analysis, Model Estimation & Hypotheses

The hypothesis used in the study is based on the Ohlson Model, which describes the relation between accounting variables and share price. In this study, the accounting variables are independent variables and the share price is the dependent variable. The six primary hypotheses framed are as follows:

  • H1: There is a positive relation between Stock price and Book Value per share
  • H2: There is a positive relation between Stock price and Earning per Share
  • H3: There is a positive relation between Stock price and Net Profit to sales
  • H4: There is a positive relation between Stock price and Return on Capital Employed
  • H5: There is a positive relation between Stock price and Return on Assets
  • H6: There is a positive relation between Stock price and Dividend per Share

3.1 Application of Ohlson Model (Initial Regression)

Dividend Per share 15.440 2.137 .125 7.225 .000

a. Dependent Variable: Share Price of Companies

The above table indicates that the accounting variables that have significant values less than .05, has a positive relation with share price. In this case, Book value per Share, Net profit margin and Dividend Per Share would only be taken ahead for establishing an association with share price. As the data collected for the study relates to time series, there could be two obstacles that would hinder the progress of this research. These two obstacles are: 1) Multi collinearity and 2) Auto Correlation.

Collinearity Diagnostic Analysis (VIF & Tolerance)

Model Unstandardized Coefficients Standardized t Sig. Collinearity Statistics
B Std. Error Beta Tolerance VIF
1 (Constant) -189.984 16.049 — -11.838 .000 — —
Book value per share 4.263 .092 .746 46.266 .000 .647 1.546
Net Profit Margin -.027 .005 -.073 -5.611 .000 .984 1.016
Dividend Per share 14.057 1.978 .114 7.108 .000 .655 1.527

a. Dependent Variable: Share Price of Companies

If the VIF value lies between 1 to 10, then there exists no multicollinearity. At the same time if the VIF value is less than 1 or more than 10, then there is multicollinearity. In the above table, the three significant accounting variables so selected based on Ohlson have VIF values below 10 and not less than 1, hence they are not collinear.

Autocorrelation Test (Durbin–Watson Diagnostic)

The next obstacle is to ensure that there is no auto correlation among the residuals of variables used in the study. The problem of auto correlation arises if the residuals of the variables are correlated. To address this problem, the Durbin–Watson test is implemented:

Model R R Square Adjusted R Square Std. Error of the Estimate Durbin-Watson
1 .814a .662 .661 629.27000 .464

a. Predictors: (Constant), Dividend Per share, Net Profit Margin, Book value per share. b. Dependent Variable: Share Price of Companies.
The Durbin–Watson test states that if the result of DW is less than 1 and more than 3 then the residuals are correlated and time series analysis must be performed. In this case, the Durbin–Watson test is less than 1 (DW = .464), hence residuals are correlated. To solve this, Exponential Smoothing model is used.

3.2 Application of Exponential Smoothing & ARIMA Models

This table describes the time series model applied for each independent variable based on their respective nature of data:

Model Description: ARIMA Time Series Specification

Variable Model ID Model Type
Book value per share Model_1 ARIMA (1,0,0)(1,0,1)
Net Profit Margin Model_2 ARIMA (0,0,1)(0,0,0)
Dividend Per share Model_3 ARIMA (2,0,2)(1,0,1)

Model Statistics: Ljung–Box Q(18) Residual Independence Diagnostic

Net Profit Margin-Model_2 0 .013 .167 17 1.000 0
Dividend Per Share-Model_3 0 .242 15.100 13 .301 0

In these results, the p-values for the Ljung-Box statistics are all greater than 0.05, which states that the residuals are made independent. The study has overcome the second hurdle that the residuals of selected independent variables are not correlated. This enabled the data to overcome the issues of autocorrelation.

3.3 Re-Applying Ohlson Model on Deseasonalized/Stationary Series

a. Predictors: (Constant), Predicted value from DPS-Model_3, Predicted value from NETPROFITMARGIN-Model_2, Predicted value from BPS-Model_1.
This table indicates that the three accounting variables explain 45.1% of variations occurring in the stock price of unsung sectors in the manufacturing industry. Hence, it can be concluded that the share price of the sectors is predictable by 45% through these accounting variables.

3.4 Pre and Post 2008 Financial Crisis Analysis

This analysis is done to understand the stability of these sectors. The stability is understood through sturdiness in the share price. After finding out fundamental strength of these sectors by establishing a relation with accounting variables and share price, an attempt is made to understand the reliability of these sectors. The reliability on these sectors depends on stability of share price. The share price fluctuates even with a minute change in the economy.

In this context, to establish the robustness of these sectors, an analysis is done on the share price and accounting variables of these sectors with a comparison of pre and post crisis that occurred in 2008 which named as sub-prime crisis. During this crisis, many established companies went bankrupt. In this context, the stability and reliability of these sectors are analysed based on pre and post crisis comparison:

  • H1: There is no significant difference in the Accounting Variables between Pre and Post Crisis.
  • H2: There is no significant difference in the Share Price between Pre and Post Crisis.

The above table presents the paired sample ‘t’ test analysis. The P value or significance value of accounting variables like Book Value per share (.000) and Dividend per share (.008) is less than .05. Hence for these two accounting variables, the Null hypothesis is rejected, indicating a significant difference in BPS and DPS between pre and post crisis periods. Whereas other Accounting Variables (EPS, ROCE, ROA, Net Profit) and even Share price do not show any difference between pre and post crisis, hence alternate hypotheses are accepted.

4. Conclusion & Key Findings for Prospective Investors

The BPS, DPS, and Net Profit Margin have a positive relationship and explanatory power over the share price of unsung sectors. It is found that these three variables explain 45% of variations in the share price of these sectors. Hence the other 55% of variations in the share price could be due to factors like inflation, interest rate, exchange rate, industry life cycles, labour conditions, trend changes, and macroeconomic parameters.

Earnings Durability & Investment Implications:

When pre and post crisis comparison was made, it was revealed that the share price of these sectors were the same. Along with share price, the accounting variables also remained the same except BPS and DPS. The BPS and DPS were different in both comparison periods. This further discloses the fact that among three accounting variables that showed positive relationship, it is net profit margin that has more explanatory power on share price than DPS and BPS.

It further explains that it is the net profit and operational efficiency of these sectors in maintaining profit during adverse macroeconomic conditions that have made them more consistent and reliable. Hence, prospective investors can undoubtedly rely on these unsung manufacturing sectors from a fundamental investment viewpoint.
